    Vacuum Packed VS Nitrogen Flushed: Which Is Better?

    Vacuum Packed VS Nitrogen Flushed: Which Is Better?

    For the past few decades, many industries have been manufacturing high volume products and shipping it all around the world. These products have to go through the manufacturing process, packaging process and finally transported to their final destination. These products need strong and durable protection to prevent their interaction with external factors such as oxygen, moisture, dust, sunlight and other harmful pollutants. For this reason, there are two popular methods used to seal these products which ensures their safe and secure transportation. These are vacuum packaging and nitrogen flushing.

    What is the difference between vacuum packaging and nitrogen flushing? What are their unique features which makes them different from each other? Which is more economical? Does one of them have certain qualities which makes it better than the latter? To answer these questions, let us discuss in detail which type of packaging prevails over the other.

      Add a header to begin generating the table of contents

      1.What is vacuum packaging?

      vacuum packaging

      Vacuum packaging is a method which is used to seal products such as food items, pharmaceutical drugs, chemical products in a hermetic seal to protect them. This process is extremely important since it provides protection against any harmful factors.

      These factors include oxygen which can serve as breeding ground for fungi and bacteria to grow, thus spoiling the products. Moreover, dust, moisture and other pollutants can damage these products as well since their interaction with them can chemically degrade these products, making them unusable.

      Vacuum packaging is a popular method to increase the shelf life of your products. It uses plastic bags, jars, containers and bottles to package these items in a vacuum like environment.

      2.What is nitrogen flushing?

      nitrogen flushing

      Nitrogen flushing, like vacuum packaging, is a method which is used to seal and package many industrial goods such as pharmaceutical medicines, chemical products, food items etc. this method uses nitrogen gas which replaces oxygen to increase the shelf life of the products and prevent them from decaying. Since nitrogen gas is heavier than oxygen, it can easily replace it and take its place.

      Nitrogen flushing too is a popular method which provides a strong and safe packaging to the products. It forms a protective barrier between the product and the harmful factors such as oxygen, air, dust and moisture which can degrade it and make it unusable.

      3.What arethe differences between vacuum packaging and nitrogen flushing when it comes to?

      1)Working principle

      Working principle

      In vacuum packaging, the container is filled with the desired product. After that, the air inside the container is sucked out, making the environment inside vacuum like. Immediately after this, the container is sealed to prevent the oxygen from rushing inside. As a result, no oxygen is left inside the container, making the environment inside completely non-reactive.

      Working principle-1

      However in nitrogen flushing, when the container is filled with the desired product inside, the oxygen inside the container is replaced by nitrogen gas. Since the nitrogen gas is heavier than oxygen, it easily replaces it. Moreover, nitrogen is an inert gas, that is, it is non-reactive and would be unable to interact with the product inside.

      Thus in vacuum packaging, all the gases inside the container are sucked out, leaving only vacuum like environment behind. However in nitrogen flushing, one gas is being replaced with another gas. Moreover, in vacuum packaging, there are no traces of oxygen left inside but in nitrogen flushing, you can find minute quantities of oxygen inside, thus making it possible to interact with the product.

      2)Structure

      a)The main structure of vacuum packaging machine is as follows:

      structure of vacuum packaging machine

      • Stainless steel: this is the main body of the machine which contains all the parts and is resistant to corrosion.
      • Vacuum chamber: this is the main compartment where the air is sucked out. A vacuum like environment is made where the package is then sealed.

        require packaging that can accommodate these sizes and shapes, such as bags or boxes.

        Other snacks, such as candy or chocolate, come in smaller sizes and shapes, so they may require packaging that is designed to hold multiple items, such as a translucent plastic container with a lid.

        • Target Market Size

        Target-Market-Size

        Different types of packaging can be used to target different market segments or to create a specific brand image. For example, eco-friendly packaging materials may be used to target environmentally conscious consumers, while sleek and modern packaging may be used to appeal to a younger demographic.

        Barrier-Protection

        It is important to understand the barrier protection factor of snack packaging as environmental influence can directly affect the freshness and quality of snacks. It is important to consider the oxygen, light, gas and moisture transmission rate before packaging of a particular snack in its packaging material.

        • Warnings And Alerts

        Warnings-And-Alerts

        The manufacturer should clearly mention all the warnings and alerts on the packaging material related to use of snacks. It will allow the consumer to get all the information related to the snacks product. Also mentioned expiry date on packaging can help the consumer to use the material within its shelf life.

        Vacuum-Packaging-VS-Nitrogen-Packaging-6

        Vacuum Packaging VS Nitrogen Packaging

        Vacuum Packaging VS Nitrogen Packaging

        In nowadays, vacuum packaging and nitrogen packaging plays a vital role in packaging industries and they are the mainstream packaging methods now. Here you will learn about their similarities and differences in some ways. Let’s figure it out together!

          Add a header to begin generating the table of contents

          1.What Is Vacuum Packaging and Nitrogen Packaging?

          Have you ever noticed any vacuum-packaged product or nitrogen-packaged product in your daily life?

          Vacuum Packaging-1

          Vacuum packaging also called decompression packaging. By extracting all the air in the packaging container and sealing it, the bag is kept in a highly decompressed state. This method is called vacuum packaging. By maintaining low levels of oxygen inside the packaging, there is no chance for microorganisms to survive. This keeps food fresh and resistant to spoilage.

          Nitrogen Packaging

          Nitrogen packaging pumps out all the air in the packaging container to make the air in the packaging bag reach a predetermined vacuum degree, and then fills it with nitrogen, carbon dioxide, oxygen, ethylene and other gases. Finally, the sealing process is completed. Nitrogen packaging can well make up for the packaging of some fragile items that cannot be vacuum-packed, such as puffed food.

          2.In What Industries Are Vacuum Packaging and Nitrogen Packaging Mostly Applied?

          Vacuum packaging and nitrogen packaging are mostly applied in food industry, pharmaceutical industry, chemical industry. In different industry, the application of them are different.

          Food Industry

          Food Industry-1

          Vacuum packaging and nitrogen packaging are mostly applied in food industry.

          Vacuum packaging is often used to package pickled products, such as sausage, ham, bacon, salted duck, etc., pickled vegetable products, such as pickled mustard, dried radish, kohlrabi, kimchi, etc., soy products, such as dried tofu, vegetarian chicken, red bean paste, etc.

          Nitrogen Packaging in Food Industry

          Nitrogen packaging is often used to package puffed, fragile and squeezed foods, such as potato chips and biscuits. When the packaging bag is filled with inert gas, it can also keep the food crisp and fresh without any harm to the body.

          Pharmaceutical Industry

          Pharmaceutical Industry

          Vacuum packaging uses special pharmaceutical vacuum bags to package drugs. Some special medicines, or tools such as surgical forceps that need to be used during the operation, will be sterilized and vacuum-packed to ensure the sterility of the equipment.

          Nitrogen Packaging in Pharmaceutical Industry-1

          Nitrogen packaging is used in pharmaceutical packaging, pharmaceutical replacement gas, pharmaceutical nitrogen-filled packaging, transportation, and Chinese herbal medicine moth prevention, anti-corrosion protection, scientific research and medical deep low temperature and cryotherapy, etc.

          Chemical Industry

          Chemical Industry

          Vacuum packaging and nitrogen packaging can also be applied in chemical industry. Vacuum packaging can be applied in sealing the solid and semi-solid chemicals and chemical reagents. Nitrogen packaging is often used to encapsulate electronic components and contact lenses, etc.

          In different industries and fields, both vacuum packaging and nitrogen packaging have different uses. But their biggest use is still in the food industry.

          3.What Are The Packaging Principles For Vacuum Packaging and Nitrogen Packaging?

          The vacuum packaging and the nitrogen packaging are the same working principle in the first step which is taking out the oxygen from the packaging bags and containers. Then the second step of the vacuum packaging is sealing the bag or the container. And the second step for the nitrogen packaging is to inject inert gases like nitrogen or carbon dioxide, etc.

          Packaging Principles For Vacuum Packaging

          Packaging Principles For Vacuum Packaging

          The principle of vacuum packaging is to extract all the air in the package, and cooperate with the packaging material with extremely low oxygen transmission rate, so that the outside oxygen cannot penetrate into the inside. Reduce the rate of oxidation and rancidity of food to ensure the freshness of food.

          Vacuum-packed food can be stored for about 14 to 20 days at 0±1°C. The shelf life of vacuum packaging itself is about 5 to 7 days longer than that of pallet packaging.

          Vacuum Packaging Principles-2

          However, vacuum packaging cannot inhibit the growth of anaerobic bacteria and the deterioration and discoloration of food caused by enzyme reactions. Therefore, food preservation also needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, radiation sterilization, microwave sterilization, etc.

          Packaging Principles For Nitrogen Packaging

          Packaging Principles For Nitrogen Packaging-1

          The working principle of Nitrogen packaging includes the process of vacuum packaging, that is, the food is packed into the bag, and then the air in the bag is extracted. When the food bag reaches the predetermined vacuum degree, nitrogen, carbon dioxide, and other gases are filled in the packaging bag, and then the sealing process is completed.

          Nitrogen Packaging Principles-2

          The working principle of Nitrogen packaging is relatively simple, that is, the oxygen that microorganisms depend on for survival is taken out, which makes the growth and reproduction speed of microorganisms drop sharply.

          Some people may confuse vacuum packaging with nitrogen packaging. In fact, nitrogen packaging includes the part of vacuum packaging, but nitrogen packaging has one more part that injects other inert gases than vacuum packaging. Nitrogen packaging procedures are a little more complicated than vacuum packaging procedures.

          4.Why Food Need To Be Vacuumed Packaged Or Nitrogen Packaged?

          Have you noticed that why most of the raw meat in the supermarket are in vacuum-packaged but some are not. That is because the vacuum-packaged meat is suitable for you to place in the refrigerator for your convenience after purchase. Other meats that are not vacuum-preserved are for you to eat fresh.

          Benefits For Both Vacuum Packaging and Nitrogen Packaging

          Improve Appeal

          Nitrogen Packaging Improve Appeal

          The nitrogen-filled packaging of the items has a beautiful and generous appearance, and you can directly see the true shape of the items, which is convenient for you to choose.

          Keep Fresh

          Keep Fresh

          Vacuum nitrogen-filled packaging is suitable for some fried foods or fruit and vegetable chips, which can not only maintain the crispness of the food. At the same time, it can effectively prevent food rancidity or extrusion. This preserves the freshness of the food.

          Prolonged Storage Time

          Prolonged Storage Time

          Vacuum nitrogen-filled packaging can choose hot-melt packaging materials at will. This kind of packaging material is low in cost, and after being filled with nitrogen, it can prevent the intrusion of external gas and moisture, and can effectively prolong the storage period of food.

          Food Safety

          Food Safety

          The survival of microorganisms is very dependent on the concentration of oxygen. After oxygen is extracted from vacuum packaging and nitrogen-filled packaging, the reproduction of anaerobic bacteria will be inhibited. In an oxygen-depleted environment, anaerobic bacteria can thrive, potentially causing food safety issues. Vacuum packaging and nitrogen-filled packaging can maintain food safety.

          Benefits of Vacuum Packaging

          Preventing Freezer Burn

          Freezer burn can occur when food is frozen without preparation. This happens when the surface of food dehydrates, which results in a dry and tough appearance. Freezer burn can also change the taste and texture of food. Vacuum bags reduce freezer burn by preventing food from being exposed to cold, dry air.

          Benefits of Nitrogen Packaging

          Vacuum nitrogen-filled packaging is most suitable for packaging of fragile materials that are not easy to squeeze, such as flowers, puffed food, snack food, etc. This just makes up for the shortcomings of vacuum packaging.

          By understanding the advantages of vacuum packaging and nitrogen packaging, you can choose the packaging way that suits you most according to your own products.

          5.What Are The Differences Between Vacuum Packaging and Nitrogen Packaging?

          Vacuum packaging and nitrogen packaging have many similarities but also have many differences. The difference between vacuum packaging and nitrogen packaging is mainly in these aspects, including packaging principles, product appearance, quality check.

          Vacuum Packaging-4

          Packaging Principles

          Vacuum packaging is mainly used to extract all the gas in the product packaging. The main machine is vacuum packaging machine. And it includes various types like single chamber vacuum packaging machine, double chamber vacuum packaging machine, etc.

          Vacuum Packaging-6

          Nitrogen-filled packaging is mainly to extract all the gas in the product packaging and fill it with other inert gases, including nitrogen, carbon dioxide, etc. The main machine is nitrogen packaging machine. And it includes various types like vacuum nitrogen flushing sealing machine.

          Vacuum Nitrogen Flushing Sealing Machine-7

          Product Appearance

          For products that are vacuum-packed, the outer packaging material of the product will collapse, making its own shape appear around the product. The appearance of vacuum-packed products will be distorted, deformed, and may cause the product to lose its physical characteristics.

          Product Appearance

          Nitrogen-filled packaging uses nitrogen or other inert gases instead of oxygen, so that the shape of the outer packaging does not change. It can well maintain the original shape of the product. Therefore, nitrogen-filled packaging is very suitable for packaging fragile products, such as puffed products.

          Product Appearance-2

          Quality Check

          There is no gas in the sealed package of vacuum-packed products, which makes the leak test impossible and needs to be tested manually. Makes quality control difficult.

          Quality Check

          Nitrogen packaging can continuously monitor the gas content in the packaging during the packaging process of the product. After the sealing of the product is complete, any leaks can be detected to ensure the integrity of the seal.

          Quality Check-1

          There may be some way more differences in the vacuum packaging and nitrogen packaging, like cost, packaging materials, packaging rolls, etc. If you want to know more, then you are free to come to us.

          6.What Are The Product Shelf Life By Vacuum Packaging and Nitrogen Packaging?

          The shelf life of different products is different. Here we focus on food. Because the shelf life of food is shorter than that of anything else. At the same time, the shelf life of the same kind of food is different when vacuum packaging and nitrogen packaging are used respectively.

          Nitrogen Packaging-6

          Product Shelf Life By Vacuum Packaging

          The main function of product vacuum packaging is to remove the oxygen inside the product. This can prevent food from spoiling and also prolong the shelf life of food. The shelf life of different foods is different. Among them, we mainly discuss meat, fruits, vegetables, dry food, powdery food.

          Meat Vacuum Shelf Life

          Meat Vacuum Shelf Life

          Meat is one of the most commonly vacuum-packed foods. Because meat is very important in your life and meat is very perishable. To keep meat fresh, meat should be vacuum-packed and stored in the refrigerator. This will maximize the freshness of the meat.

          Vegetables Vacuum Shelf Life

          Vegetables Vacuum Shelf Life

          Vegetables have a slightly shorter shelf life because they contain too much water inside. And the vegetables will continue to respire in the vacuum packaging, resulting in loose sealing. Therefore, vacuum-packed vegetables should be eaten as soon as possible.

          Fruits Vacuum Shelf Life

          Fruits Vacuum Shelf Life

          Fruits have an even shorter vacuum shelf life than vegetables. Because fruits contain more water than vegetables. And if the fruit is left for too long, the water in the body will evaporate, causing the loss of nutrients in the fruit. It will also damage the taste of the fruit. Fruit that has been vacuum-preserved should therefore be consumed as soon as possible.

          Dry Food Vacuum Shelf Life

          Dry Food Vacuum Shelf Life

          Dry food including rice, beans, nut, etc. have a longer vacuum shelf life. Because this type of food contains less water in the body. And this kind of food is more suitable to be preserved in vacuum.

          Powdery Food Vacuum Shelf Life

          Powdery Food Vacuum Shelf Life

          Vacuum packaging can effectively prevent powdery food from hardening and deterioration due to air absorption during storage. The vacuum shelf life of Powdery food can be extended by 2 to 3 times.

          Product Shelf Life By Nitrogen Packaging

          Product Shelf Life By Nitrogen Packaging

          Oxygen is a substance that microorganisms depend on for survival. By using nitrogen, like carbon dioxide and other inert gases to replace the oxygen in the packaging bag. This delays the growth and development of microorganisms very well, and prolonged the shelf life of food

          Nitrogen Packaging Shelf Life-2

          The extension of the shelf life of food by Nitrogen packaging is longer for foods with lower moisture content, such as snack foods, coffee, dry goods, etc. For fresh fruits and vegetables with higher moisture content, etc., the extended period of shelf life is shorter. For meat products, the preservation effect of cooked food is far better than that of ready-to-eat meat.

          Nitrogen Packaging Shelf Life-3

          In addition to vacuum packaging and nitrogen packaging, there are other packaging ways. These packaging ways have completely different effects on the shelf life of food. These methods include air-permeable over-wrap, master pack low oxygen, master pack high oxygen, etc. These methods have completely different effects on the shelf life of food.

          Nitrogen Packaging Shelf Life-4

          Different products have different storage and packaging methods. But you can choose the best or most suitable packaging way for your product. However, how to choose the most suitable packaging way according to your product? The following questions are perfect for your deep thinking.

          7.How To Choose Vacuum Packaging and Nitrogen Packaging?

          How to decide whether you should adopt vacuum packaging or nitrogen packaging according to your products? With this in mind, you need to think about it from several point views of the packaging costs, the packaging materials, packaging machines.

          Packaging Costs

          Packaging Costs

          During the packaging process of nitrogen packaging, additional inert gas, such as nitrogen, carbon dioxide, oxygen, ethylene, etc., needs to be filled. Some of these noble gases are very expensive to manufacture. Will increase your production costs. Therefore, if you can use vacuum packaging products, try not to choose nitrogen packaging.

          Packaging Materials

          Packaging Materials

          Especially for fragile snack foods or puffed foods, nitrogen packaging must be used. Because of the use of nitrogen packaging products, the extrusion, breaking and sticking of food can be well avoided. It is more convenient for food storage and transportation. At the same time, it can ensure the crispness of puffed food.

          Packaging Machines

          Packaging-Machines-6

          If you have many series of products that need to be packaged. Then you need to consider vacuum packaging machine or nitrogen gas flushing machine. Among them, there are many product lines of vacuum packaging machine. There are more options. You can choose whether to consider vacuum packaging or nitrogen packaging from the perspective of the machine.

          8.What Products Can Not Be Vacuum Packaged or Nitrogen Packaged?

          Though vacuum packaging and nitrogen packaging are goods ways fr packaging different things and products, there are also a lot things that you can not pack with these packaging ways.

          Products Can Not Be Vacuum Packaged

          Quilt or Clothing

          Quilt or Clothing

          Some quilts or clothes will have a lot of wrinkles after being vacuum-packed. Even if these folds are taken out or re-watered, there is no way to restore them to their original shape. Therefore, such quilts and clothing are not recommended to be vacuum packed.

          Sharp Product

          Sharp Product

          Vacuum packaging mainly uses transparent film outer packaging bags to vacuum seal things that need to be vacuumed. Therefore, if the outer surface is very sharp, it is easy to scratch the outer packaging bag. Such items are not suitable for vacuum packaging. For example, among the fruits are durian and so on. Knives, forks and the like are included in the kitchen utensils.

          Liquid Supplies

          Liquid Supplies

          When liquid supplies are vacuum packaged, they need to be completed in a sealed vacuum working chamber or studio. When the liquid in Liquid products is placed in a sealed vacuum working chamber or studio, it is prone to overflow and other phenomena. Therefore, Liquid products are not suitable for vacuum packaging.

          Products Can Not Be Nitrogen Packaged

          Non-food Product

          Non-food Product

          First of all, most liquid, semi-fluid, solid granular, powdery, pasty foods, fresh fruits, vegetables, rice, flowers, chemicals, precious medicinal materials, valuable calligraphy and paintings, electronic components, etc. are suitable for nitrogen packaging. However, nitrogen packaging is a method with a higher cost than vacuum packaging. Therefore, non-food or low-cost products are not suitable for nitrogen packaging.

          When you are choosing related machines for vacuum packaging and nitrogen packaging, you should also pay attention to these points.

          Conclusion

          When you are applying the vacuum packaging and nitrogen packaging to your business, it will do a great job and bring good prospect to your business. If you have any need or any question about this type packaging ways or packaging machines, you are welcome to come to us anytime, and we will do our best to fulfill your quests.

            Thickness

            Thickness

            Actually,the most common thicknesses of vacuum seal bags in the market are 3 Mil,4 Mil and 5 Mil.Maybe you will be confused about what’s the meaning of Mil,or maybe you thick it refers to millimeters ,this cognition is wrong,in fact,1 Mil is 1/1000th of an inch.

            The thickness of the vacuum seal bag can represent its strength in a certain degree,it can represent how durable it is.The thicker the bag is,the more durable it is,and the longer storage time it can provide.

            One thing which is less known is that,in most cases,the thicknesses of the two sides of vacuum seal bag are different,the back side is always thicker than the front side.Maybe you will ask why,well,the surface of back side of vacuum seal bag is textured,for the purpose of blocking the air.
            It has already been mentioned in the last question that there are three types of common thickness of vacuum seal bags:3 Mil,4 Mil and 5 Mil,and in this part,they will be compared with each other.

            Size

                9. What Is the Working Principle of a Food Vacuum Packaging Machine?

                Sealing-Process-Table

                Sealing Process Table

                The main function of the food vacuum packaging machine is to remove oxygen, which is beneficial to prevent the food from spoiling.

                The working principle of the food vacuum packaging machine is relatively simple.

                Because food spoilage is mainly caused by the activity of microorganisms, and most microorganisms (such as molds and yeasts) require oxygen to survive.

                Food-Vacuum-Packaging-Line-Chain

                Food Vacuum Packaging Line Chain

                Vacuum packaging uses this principle to remove the oxygen in the food in the packaging bag, so that the microorganisms lose the environment for survival.

                Experiments have shown that when the oxygen concentration in the packaging bag is less than 1%, the growth and reproduction speed of microorganisms will drop sharply. When the oxygen concentration is lower than 0.5%, most microorganisms will be inhibited and stop multiplying.

                Oxygen Content Table

                (Note: Vacuum packaging cannot inhibit the reproduction of anaerobic bacteria and the deterioration and discoloration of food caused by enzymatic reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickled etc.)

                In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum oxygenation is to prevent food oxidation.

                Because oily foods contain a lot of unsaturated fatty acids. Unsaturated fatty acids are easily oxidized by the action of oxygen, thus making the food taste bad and spoiled.

                Carbondioxide-Content-Table

                Carbon dioxide Content Table

                In addition, oxidation can easily cause the loss of vitamin A and vitamin C. The unstable substances in food coloring are exposed to the action of oxygen, darkening the color.

                Therefore, oxygenation can effectively prevent food spoilage.

                In addition to the function of oxygenation and quality preservation, vacuum packaging mainly has the functions of anti-pressure, gas resistance, and preservation. This can more effectively keep the original color, aroma, taste, shape and nutritional value of the food for a long time.

                In addition, there are many foods that cannot be vacuum-packed, but must be vacuum-inflatable packaged. Such as crunchy and brittle food, and food that is easy to agglomerate and easy to deform and lose oil; food with sharp edges and corners or high hardness that will pierce the packaging bag, etc.

                Potato-Chips-Vacuum-Packaging-Machine

                Potato Chips Vacuum Packaging Machine

                After the food is vacuum inflated, the inflation pressure in the packaging bag is stronger than the atmospheric pressure outside the packaging bag. This can effectively prevent the food from being crushed and deformed under pressure, making the appearance of the packaging bag more beautiful.

                The vacuum inflatable packaging is filled with a single gas such as nitrogen, carbon dioxide, oxygen, or a mixture of two or three gases after vacuum.

                Among them, nitrogen is an inert gas, which plays a filling role to maintain a positive pressure in the bag. In this way, the air outside the packaging bag can be prevented from entering the bag, which has a protective effect on the food.

                Nitrogen-Vacuum-Packaging

                Nitrogen Vacuum Packaging

                Carbon dioxide can be dissolved in various fats or water to form carbonic acid that is less acidic. This carbonic acid can effectively inhibit the activity of microorganisms such as mold and spoilage bacteria.

                Oxygen can inhibit the growth and reproduction of anaerobic bacteria, and can maintain the freshness and color of fruits and vegetables. High concentrations of oxygen keep fresh meats bright red.

                10. What Are the Components of a Food Vacuum Packaging Machine?

                There are 5 parts of the commercial food vacuum packaging machine:

                Whole steel structure: The shell of food vacuum packaging machine is usually made of stainless steel or carbon steel.

                Stainless steel material is not easy to corrode and rust, and it can be used for a long time. It is more suitable for a relatively humid working environment; the vacuum chamber is made of glass.

                Stainless-Steel-Shell

                Stainless Steel Shell

                 Vacuum pump: The vacuum pump is the main component of the food vacuum packaging machine, and it is the heart of the food vacuum packaging machine. Generally, the bigger the vacuum pump is and better the food vacuum packaging machine will be, and of course the more expensive it is.

                Therefore, considering the cost-effectiveness factor, the configuration of the vacuum pump is configured according to the size of the vacuum chamber.

                Vacuum Pump(1)

                Vacuum Pump

                Electronic components: The electronic components of general food vacuum packaging machines are mainly composed of solenoid valves, frequency converters, relays and computer control panels.

                Sealing Ring

                Wearing parts: The main wearing parts of the food vacuum packaging machine include heating strips, insulation cloth, etc. Usually these wearing parts need to be replaced regularly.

                Sealing ring: The vacuum chamber is equipped with upper and lower sealing rings. If the machine doesn’t have seals, then the vacuum can’t be finished.

                11. What Should You Consider Before Buying a Food Vacuum Packaging Machine?

                Food Vacuum Packaging Machines are divided into commercial and household use. You can judge from the following differences: machine size, price, power, energy consumption, vacuum weight, vacuum times, efficiency, etc.

                If you need a common household small food vacuum packaging machine, then the price does not need to be expensive. But you’ll need to choose a textured bag so you can vacuum it. You can easily buy it online, TV shopping and offline or contact us.

                Size(1)

                Size

                 If you need a commercial food vacuum packaging machine, the price is generally higher. And the vacuum bag for packaging needs to be thicker, but does not need a textured bag.

                Packaging Bags Without Texture

                And you need to consider the following principles:

                Packing speed: In order to improve production efficiency, a double-chamber or multi-chamber vacuum packaging machine can be selected to improve the progress of the entire production.

                Whether the packaged items need to be filled with other protective gases: Optional multifunctional vacuum packaging machine with inflation device. For example, potato chips need to be filled with nitrogen during vacuum packaging to maintain good freshness and taste.

                 Requirements for the vacuum degree of the packaged items: If the packaged items need to be well preserved under the condition of high vacuum degree, you need to choose a Chamber Vacuum Packaging Machine.

                Chamber-Vacuum-Packaging-Machine(1)

                Chamber Vacuum Packaging Machine

                The requirements of the state of the components of the packaged items for the vacuum packaging machine. Such as solids, granules, cooked food, liquids, etc.

                When you are buying food vacuum packaging machine, when packing solids, granules and other dry and non-corrosive materials, you should choose a vacuum packaging machine made of aluminum alloy.

                When packaging with soup, materials with high salt and acid content, you should choose a vacuum packaging machine made of stainless steel or aluminum-magnesium alloy.

                12. Why Does the Vacuum Packaging Machine Leak Air During Packaging?

                Air-Leaking-of-Bad-Sealed-Packaging-Bag

                Air Leaking of Bad Sealed Packaging Bag

                There are many reasons why the vacuum packaging machine cannot be vacuumed cleanly. The main reasons are: the vacuuming time is too short. The vacuum pump is aging or not properly maintained.

                The vacuum studio is not well sealed, and there is air leakage when vacuuming. The power of the vacuum pump is too small and the actual pumping speed ratio does not match, and the vacuum cannot be fully pumped.

                The solution is as follows:

                You should prolong the vacuuming time.

                You should replace the vacuum pump, and pay attention to maintaining and replacing the vacuum pump oil timely.

                If the vacuum pump has not been maintained for a long time, you should first clean up the waste oil in the vacuum pump before replacing it.

                (Generally, the first maintenance is after the vacuum packaging machine has been working continuously for 300 hours.

                After that, the maintenance will be carried out after the vacuum packaging machine has been working continuously for 500 hours.)

                Proper-Operation

                Proper Operation

                 You should check the vacuum chamber for leaks. If there is an air leak, you must replace the sealing strip in time.

                If the vacuum pump is too small to achieve the desired vacuum effect, you need to replace it with a higher-power vacuum pump.

                After the mechanical equipment is bought and used for a period of time, you must pay attention to its maintenance.

                Just like a car, it needs regular maintenance. If maintenance is not in place, no matter how good the equipment is, it cannot be used for a long time.

                13. How Long Can Vacuum-packed Food Generally be Stored?

                Vacuum-packed food can generally be stored for about 1 to 12 months. The storage time varies depending on factors such as the type of food and the processing before packaging.

                Different types of food after vacuum packaging have different storage times at room temperature.

                In general, fresh agricultural products or lightly processed meat products can be kept at room temperature for 2 days. But after vacuum packaging, it can be extended to 6 days, and some can be extended to 18 days.

                 Dried fruit vacuum-packed food can be stored for a long time, even more than twelve months.

                Storage-Time-TableStorage Time Table

                Cooked vacuum-packed food will keep for a shorter period of time. Typically, it stays fresh for around 15 days in winter and spring. And in summer and fall, it will only keep for about 4 days to about a week, but preferably needs to be refrigerated.

                14. How to Vacuum Pack Food With Liquid?

                At present, the most common vacuum packaging of pure liquids on the market is Tetra Fino Aseptic, which is what we see as boxed milk. This is the vacuum packaging of pure liquids.

                Tetra-Fino-Aseptic

                Tetra Fino Aseptic

                 When the food with soup is vacuum packed, you can choose a liquid vacuum packing machine. This machine is provided with a groove. This allows the liquid to sink without spilling during vacuum packaging.

                There is a double-chamber concave liquid vacuum packaging machine and a rolling vacuum packaging machine. By adjusting the angle of the machine, a certain angle of inclination can be created to prevent the soup from spilling.

                15. Can You Eat the Leaking Vacuum-packed Food?

                Vacuum-packed-greens

                You would better not eat food that is leaking air.

                It is best for you not to eat food that leaks air, because the vacuum packaging is for the purpose of preventing air from entering, preventing oxidation, and preventing corrosion.

                If the vacuum packaging leaks, it proves that the air enters, so the items may deteriorate.

                Inflatable packaging is generally filled with nitrogen and carbon dioxide, which can protect fragile food and prevent corrosion.

                Once air leaks, the food will be oxidized with the air, and it is likely to deteriorate.

                If the air leaks for a long time, it is impossible to judge whether the food is edible or not. It is likely to cause symptoms of abdominal pain, bloating, and diarrhea.

                Similarly, food that has no air leakage but has expired is also inedible.

                16. What Should You Do When Choosing Food Vacuum Packaging Bags?

                Food-Vacuum-Packaging-Bags

                Food Vacuum Packaging Bags

                The outer packaging of food vacuum packaging bags needs to be marked with text. Label the factory name, factory address, and product name. And the words “for food” should be clearly marked.

                Products are accompanied by a product inspection certificate after leaving the factory. This food vacuum packaging bag is relatively safe.

                Colored vacuum bags (dark red or black, etc. currently on the market) cannot be used for food packaging. Because these vacuum bags are often made of recycled plastic.

                Food-Vacuum-Packaging-Bags(1)

                Food Vacuum Packaging Bags

                Food vacuum packaging bags are odorless when they leave the factory. Vacuum bags with special odors cannot be used as food vacuum bags.

                Try to use food vacuum packaging bags that are not coated or plated.

                In the current packaging design, in order to make the packaging bag more beautiful and corrosion-resistant, many manufacturers have used a large number of materials with coating.

                This not only brings difficulties to the recovery and reuse of materials after the products are scrapped. And most of the coating material itself is toxic, if you use these food packaging bags, it will bring great harm to your health.
