    POF and PVC shrink wraps have a maximum gauge thickness of around 150 gauge. PE shrink wraps have a high thickness of up to 1200 gauge which is ideal for marine use. However, it does not have a high shrink rate.

    8.What are Centerfold Shrink Wrap and Single Wound Shrink Wrap and Their Thicknesses?

    There are two common types of shrink wraps depending upon their arrangement on the roll. These are discussed below:

    Centerfold Shrink Wrap

    Centerfold Shrink Wrap and Single Wound Shrink Wrap

    Centerfold Shrink Wrap

    This type of shrink wrap is typically folded in half and then wrapped around a centre to form a large film roll. For instance, a 10 cm centrefold shrink wrap is unwounded to give a 20 cm shrink wrap. This shrink wrap is available in 35-100 gauge thicknesses while 60 and 75 gauge are commonly used.

    Single Wound Shrink Wrap

    It is also known as single-layered shrink wrap. It is available as a flat sheet wound around the core. However, this type of shrink wrap is twice as heavy as centrefold shrink wrap. It comes in a 35-150 gauge range. Ultra-thin single-wound shrink wrap ranging between 35-50 gauge is favoured by users.

    9.Is There a Difference Between Heat Shrink Wrap Thickness and Stretch Wrap Thickness?  

    Heat Shrink Wrap Thickness

    Heat shrink wrap and stretch wrap differ in their mode of application. Heat shrink wrap shrinks on applying heat and adapts to the curves of the product being wrapped. Stretch wrap is applied by stretching and completely envelops the product.

    Consequently, both these wraps also differ in their thickness. Stretch wrap is way thinner than heat shrink wrap. It is because with stretch wrap not much protection is needed.

    When packing smaller items, the heat shrink wrap of 1 Mil (100 gauge) thickness is used while stretch wrap of thickness 0.75 Mil (75 gauge) is utilized for the same function.

    Similarly, when bundling large cargo pallets, the thickness of heat shrink wrap could be as high as 12 Mil but for palletizing purposes, the stretch wrap with a thickness of up to 5 Mil is utilized.

    Furthermore, the highest thickness level of heat shrink wrap is 12 Mil (1200 gauge) and for stretch wrap maximum thickness is 5 Mil (500 gauge).

    10.What Is The Relationship Between Gauge And Shrink Wrap Thickness?

    Relationship Between Gauge

    Gauge and Shrink Wrap Thickness- Picture Courtesy: Cantwell Cleary

    The gauge has paramount usage in industrial settings and is commonly used for mentioning shrink wrap thickness. The value of the gauge is directly proportional to the thickness of the shrink wrap. This means that if the shrink wrap has a lower gauge value it means that it is thinner and vice versa.

    For instance, 40 gauge shrink wrap is thinner while 140 gauge is thicker. Moreover, thinner gauge shrink wrap contracts and encloses around the product without needing much heat. However, the shrink wraps with higher gauges necessitate a significantly higher amount of heat for wrapping.

    11.How Does The Thickness Of Shrink Wrap Impact Its Price?

    Thickness Of Shrink Wrap Impact Its Price

    The price of the shrink wrap is directly influenced by its width, type, and, thickness. Generally, the thicker shrink wrap has a higher price cost than the thinner shrink wrap. This is because the manufacturing cost of thicker shrink wrap is higher.

    The thick shrink wrap demands more starting material and is fabricated with more quantities of plastics, resins, and additives. Furthermore, the thick shrink wrap needs specialized equipment for extrusion that runs on high power. The equipment running cost also influences the price of shrink wrap.

    In addition to these factors, the application of thick shrink wrap is also a deciding aspect when it comes to its purchase price. Thick shrink wraps are heavy-duty thus their buying cost is higher.

    Thinner shrink wraps are fabricated using fewer raw materials and are not processed with specialized machines, therefore, these shrink wraps are fairly inexpensive than their thick counterparts.

    12.Do the Size and Weight of Products Affect Shrink Wrap Thickness?

    Size and Weight

    Heavier Objects and Shrink Wrap Thickness- Picture Courtesy: The Wickery

    Yes, the size and weight of products are pivotal factors that impact the shrink wrap thickness. Heavier and larger objects such as boats, and pallets have large surface areas, consequently, they are enclosed in thicker shrink wrap as there is a higher chance of their damage during rough transportation and treatment. These thicker shrink wraps offer products ultimate protection.

    Thicker shrink wraps are more robust and long-lasting. They can endure higher strain and do not rupture or tear due to heavier loads. Thinner shrink wraps are normally for lightweight and smaller items that do not need heavy protection.

    Besides size and weight, the contours and designs of products impact the thickness of shrink wrap. Usually, objects with sharp corners and irregular designs are packed in thicker shrink wraps. These sharp corners of products can rip the shrink wrap, so, they are enveloped in thicker shrink wraps because the latter withstand the tearing or puncture.

    13.How Do Environmental Conditions Influence The Durability Of Shrink Wrap Thickness?

    Yes, environmental conditions significantly impact the durability of shrink wrap thickness. These harsh surroundings can degrade the shrink wrap and affect its protectiveness. The relation between environmental conditions and durability of shrink wrap thickness is listed below:

    Temperature

    Temperature

          Compare to shrink sleeve labeler, traditional labeling machine is composed of fewer parts. These are:

          Product Sensor

          It senses the presence of containers and sent the signal to controller for preceding the process.

          Controller

          It counts the numbering of items and order command to release the labels accordingly.

          Supply Reel

          Labels are combined in unified form as a roller on supply reel.

          Peel Bar

          It peels the label from laminated liner and pushes it towards bottle.

          Labeling Head

          Parts associated with labels are located in labeling head. Labels are delivered until machine realizes the gap between containers thus stop labeling and wait for another one.

          Applicator Brush

          When label is peeled off by peeling plate the brush pasted it on bottle and exert some pressure to get the label stick to the bottle.

          Procedure

          Shrink Sleeve Labeler

          Shrink Sleeve Labeler

          The process of shrink sleeve labeling is a little bit lengthy. It starts when unlabeled containers are transported through in feed conveyor. Rotating screw feeder meters the product.

          On the other side, unwinding of film from reel initiates the movement and the film is produced in form of continuous web. During this mechanism label registration sensor detect the registration code on each label after which the label is turned into round shape.

          The labels are then carried out by shooter motor which accurately place it over product and the container is then passed through heat tunnel where the film shrinks and transform into the shape of bottle. Eventually the operation completes and material is discharged.

          Traditional Labeling Machine

          Traditional Labeling Machine-3

          In contrast to shrink sleeve labeler, traditional labeling method is quite simple with few steps. These are:

          Once machine is switched on after fixation of parameters the operation begins. Bottles kept on conveyor belt are sensed by controller and the process of labeling initiates. The controller allows the labeling reel to release labels and the blade cuts them for separate containers.

          When label is applied on container a light pressure is applied due to which the label simply adheres to the surface of object.

          Pros

          Pros

          Shrink Sleeve Labeler

          Shrink Sleeve Labeler-4

          Efficient

          The process of shrink sleeve labeling is fast as the product just passes through the heat tunnel and film itself shrinks to the shape of bottle.

          Adaptable

          Shrink sleeve labeler is highly flexible as it conforms to irregular shaped bottles and easily transforms the label to shape of containers. It creates perfect shrinkage without wrinkles in unusual shapes. It is also capable of labeling and decorating on complex shaped containers.

          Size

          Shrink sleeves are mostly of big size they cover the entire body of bottles and offer 360 degree area to print labeling content. Thus provide enough space to manufacturers for displaying the important information which they want to deliver to customers.

          Attractive Appearance

          Its use can benefits you in so many ways among which the prominent one is the beautiful look which it gives to your products. This ultimately catches the attention of buyers and increases their interest in such products.

          Durable Seal

          Shrink sleeve labeling works as anti tamper agent and provide strong rigid seal which is difficult to damage.

          Cons

          Cons

          Shrink Sleeve Labeler

          Expensive

          Expensive

          Shrink sleeve labeler is expensive in nature as the machine comprised of various parts with complicated structure.

          Traditional Labeling Machine

          Slow

          Slow

          The process of traditional labeling is slow due to the peeling of labels and the gap between containers which stops the process until container is close to labeling head.

          Small Size

          Small Size

          Traditional labels are often small in size due to which only product or company names can be printed.

          4.Composition Of Shrink Sleeve Labeler Vs Traditional Labeling Machine?

          Traditional Labeling Machine-6

          There is huge difference between shrink sleeve labeling and traditional labeling on the basis of their composition. Material from which these two are made is described below separately:

          Shrink Sleeve Labeling

          Shrink Sleeve Labeling-7

          Plastic

          Shrink sleeve labeling is always made from strong plastic because the film has to pass through the heat which other material cannot endure. Plastic used in such labeling is durable, tamper resistant and 100% recyclable. As plastic is more flexible compare to paper, it can be transformed into any type of bottle shape covering it from top to bottom.

          Traditional Labeling Machine

          Paper

          Paper

          Compare to shrink sleeve labelling, traditional labeling is mostly produced from paper, cards or rarely from light plastic. Although it cannot be recycled due to deterioration caused by moisture but its fast decomposition makes it environmental friendly.

          5.Which Machine Is More Cost Effective-Shrink Sleeve Labeler OR Traditional Labeling Machine?

          Cost Effective-Shrink

          How the cost of shrink sleeve labeler and traditional labeling machine differs one from another is what we have explained below:

          Shrink Sleeve Labeler

          Shrink sleeve labeler is 25% more costly than traditional labeling machine. The reasons are; use of strong plastic to endure the heat pressure, the large amount of films as whole body of containers are to be covered and complex components of machine which are expensive.

          Traditional Labeling Machine

          Traditional labeling machine is less expensive than shrink sleeve labeler because of the less parts requirement and its use of paper labels which are relatively cheaper than plastic. Thus it is more economical and suitable for processing number of products.

          6.Which Labeling Machine Is Popularly Used Between Shrink Sleeve Labeler Machine And Traditional Labeling Machine?

          Shrink Sleeve Labeler

            Thankfully, the working of the shrink wrap tunnel machine is simple as compared to its complex design. Well, that is not true as it designed in a completely different way so it also has different working process.

            Initial stage

            Initial stage

            At the initial stage when the product enters into the machine it moves towards the tunnel where all the processing takes place.

            Once the product started its movement the wrapping film goes down towards the tunnel and adjust itself according to the size of the product.

            Middle Stage

            It is a crucial stage in which the wrapping process takes place as once the product enters into the tunnel it gets wrapped and when the product is wrapped with the plastic film.

            Then there comes the heating system into action which simply perform the heating operation and heat the wrapped product to give the wrapping a shape according the design and size of the product.

            You can say that in this stage multiple processes takes place all at once.

            Whereas, a plastic wrap machine just simply wraps the product with a plastic film and seal it at the end.

            You can give desired shape to your product using the shrink wrap tunnel machine but you can not do that by using a plastic wrap machine.

            8.Why heat is necessary in shrink wrapping?

            shrink wrapping

            Heat is very important element in a shrink wrap tunnel machine processing because it plays a vital role to wrap the product.

            For example, once you wrap the product with a PVC or polyolefin film then how you are going to shrink it that is the reason heat is important.

            And by using hot air you can perfectly wrap the product with a plastic film so it is a kind of main piece of shrink wrap processing. You will get quality wrapped product while using heat in the form of hot air.

            9.What types of materials you can use to work with shrink wrap tunnel machine?

            You can basically work with three main plastic wrapping films while using shrink wrap tunnel machine.

            PVC

            PVC

            Polyvinyl Chloride is a plastic film that comes in multiple kinds of flexibility and rigidness depending upon the business requirement you can select that best suit your needs.

            It comes in such a thin quality and visibility that you can stretch it up to a limit and also see through or your can choose the invisible one.

            PE

            Polyethylene film is extracted from some natural resources such as hydrocarbons that we get rom or daily life elements like gasoline or petroleum elements.

            It is one of the widely used film most of the plastic bags are formed with PE.

            POF

            POF

            Polyolefin is a polymer based plastic film which is taking over the wrapping industry in all most every sector.

            POF is very effective when it comes to shrink wrapping and most of the shrink wrap tunnel machine workers use this film because of its shrinkable ability.

            10.Can a shrink wrap product get wet?

            shrink wrap product

            No way, once the product is wrapped by using a shrink wrap tunnel machine then it is very hard for water to get inside.

            But in some cases this can happen if there is any kind of tampering happen during the wrapping then may be there are some holes left on the wrap so make sure that no tempering happen while wrapping the product.

            Once the wrapping is done the shrinking of the film left no holes open to make sure that the item inside remain safe, secure and durable in the best possible way.

            11.How to troubleshoot shrink wrap tunnel machine problems?

            As a fact,there are two common packaging methods in the market-shrink packaging and vacuum packaging,if you always go to the supermarket,maybe you will find that some products are respectively packaged by these two different packaging methods.

            But,have you really thought about the two packaging methods?Why some products are shrink packaged while others are vacuum packaged?What are the differences between them?Which one is suitable for your demand?Now please explore the answers from this article.

              Add a header to begin generating the table of contents

              1.What is shrink packaging VS vacuum packaging?

              At the first part,we need to resolve the basic problem,what is shrink packaging and what is vacuum packaging,in other words,what are the definitions of them.

              Shrink Packaging

              Shrink Packaging

              Shrink packaging is to wrap product with a plastic film which is accord with the size of it,then begin the operation of heat-sealing,under the influence of the heat,plastic film is shrinking constantly until it fit tightly to the surface of product.

              Shrink packaging originated in the mid-1960s and developed rapidly in the 1970s,it is widely used by some economically developed countries.

              Vacuum Packaging

              Vacuum Packaging

              Distinct from shrink packaging,vacuum packaging is to extract the air from the container of product,to make it under a low-oxygen condition in which microorganism can not survival and reproduce.

              The appearance of vacuum packaging is earlier than shrink packaging,it first appears in the 1940s,and after 1950s,it has developed in a fast speed.

              2.What are the effects of shrink packaging VS vacuum packaging?

              In the basic case,the purpose of shrink packaging and vacuum packaging is to storage products for longer time,and besides,they also have other effects,which are as follows:

              Effects of Shrink Packaging

              Effects of Shrink Packaging

              Moistureproof and Waterproof

              Moistureproof and Waterproof

              Because of the leakproofness of shrink packaging,you can ensure that there is no moisture inside the packaging film,therefore,shrink packaging is moistureproof and waterproof.

              Anti-pollution

              Anti-pollution

              Through shrink packaging,the products are sealed in plastic films so they will not contact with dust in the air or other environmental elements,as a result,shrink packaging achieves the function of anti-pollution.

              Avoid Shock

              Avoid Shock

              In fact,when the product is stuck, the plastic film which is wrapped around it can plays a role in buffer,protects the product to a certain degree.Moreover,if the product which is shrink packaged is a fragile object,the film can prevent splashes when the product is broken.

              Effects of Vacuum Packaging

              Effects of Vacuum Packaging

              Prevent food oxidation

              Prevent food oxidation

              Sometimes,there are some fatty foods,they contain a lot of unsaturated fatty acids,which are easy to influenced by oxygen and come to oxidation.Vacuum packaging extract the air,so it can effectively avoid food oxidation.

              Prevent Pollution

              Prevent Pollution

              The reason why vacuum packaging can prevent products from pollution is that,by using vacuum packaging,the products is wrapped in the packaging pouch and don’t touch outside environment,so possible pollution is avoided.

              Keep a Good Appearance

              Keep a Good Appearance

              The same as others,principle of this is also because vacuum packaging can keep food in a low oxygen condition,which inhibits the survival and reproduce of the microorganism,so that the food can keep in a original appearance.

              Crush Resistance

              Crush Resistance

              During the vacuum packaging,after extracting the air, there are other gases filled into packaging pouch,then the air pressure in the pouch is greater than the air pressure outside the pouch, which can effectively prevent the crushing deformation of the food and does not affect the appearance of the pouch.

              3.How many types of shrinking films and vacuum packaging pouches there are?

              In general,there are different types of shrinking films and vacuum packaging pouches,which are made of different materials and are adapted to different products.

              Shrinking Films

              Shrinking Films

              PE Film

              This kind of film is suitable for wine, cans, mineral water, all kinds of beverages, cloth and other products of the whole collection packaging,it takes advantages of flexibility and tear resistance ability.

              In addition,the PE film is hard to be damaged and the shrinking percentage of it is high.

              PVC Film

              The PVC film has features of high transparency,high glossy and high shrinking percentage.

              POF Film

              POF refers to multi-layer co-extruded polyolefin thermal shrinkage film,it has high surface gloss, good toughness, high tear strength, uniform thermal shrinkage.

              OPS Film

              OPS film is type of shrinking film which is standard to the environmental protect requirements,it has high strength, high rigidity, stable shape, and has good gloss and transparency.And the OPS film is convenient in processing,coloring and printing.

              Pet Heat-shrinkable Polyester Film

              This film is stable under normal temperature,but while the temperature up to glass transition temperature,it starts to shrink.It has many advantages,and the most special one is that there is no renaturation of it, which makes it has a certain anti-counterfeiting function.

              Vacuum Packaging Pouches

              Vacuum Packaging Pouches

              Aluminum Foil Vacuum Pouch

              The material of this vacuum pouch is generally PET/AL/CPE or PET/NY/AL/CPE,This product has good performances such as anti-static, oxygen, shielding, moisture-proof, shading function and excellent heat sealing.

              Aluminum foil vacuum pouch is widely used in food, electronics, chemical and other industries. Because the raw material of aluminum foil itself is expensive, the cost of vacuum will be relatively high.

              Nylon Co-extrusion Vacuum Pouch

              Nylon co-extrusion vacuum pouch is made of PA, EVOH and PE, PP, TIE and other resins.It has the characteristics of pollution-free, high barrier,low cost, small capacity ratio, high strength, flexible structure and so on,and it makes the production process of food packaging materials realize pollution-free.

              Nylon Composite Vacuum Pouch

              The material of nylon composite vacuum pouch is similar to nylon co-extrusion vacuum pouch,the difference between them is the technology,the composite pouch is made up of multiple layers of materials.

              PE Vacuum Pouch

              PE vacuum pouch is the most widely used vacuum pouch in the market because the price is cheap,that is,high cost performance.But,it has disadvantages of high breathability and low leakproofness,as a result,it’s easier to be broken.

              4.What are the pros and cons of shrink packaging VS vacuum packaging?

              Certainly,nothing in the world is perfect,both the two packaging methods have their own pros and cons,which will be explained in detail to the below.

              Pros of Shrink Packaging

              Pros of Shrink Packaging

              Adaptable

              As is mentioned above,shrink packaging to heat the film which is cover around the product,then it is wrapped tightly to the products,so that it is adapted to products of various shapes and sizes.

              Transparency

              The film which is around the product is transparent,so people can directly see the appearance of the product,which is convenient for purchase.

              Stable

              The close and tight contact between the film and the product can increase the stability of the product,prevent it from moving position.

              Save Labor

              Both the packaging technology and packaging equipment of shrink packaging are simple,which makes it convenient for shrink packaging realizes automatically production,save the investment of labor.

              Cons of Shrink Packaging

              Cons of Shrink Packaging

              Can Not Be Recycled

              One of the cons of shrink packaging is that it is hard to recycle,as the shrink packaging is to tightly wrap the product itself,the recovery rate is relevantly reduced.

              Not suitable For Heat Sensitive Products

              If there are some heat sensitive products,shrink packaging is not appropriate for them.So,in fact,shrink packaging isn’t suitable for all kinds of products.

              Energy Consumption

              In addition,the precondition of shrink packaging is heat,to reach the required temperature,there is much energy that consumed.

              Pros of Vacuum Packaging

              Pros of Vacuum Packaging

              Retain the Original Taste

              Vacuum packaging can make sure that food is sealed in packaging pouch,it will not contact with air,so it can keep the same condition as when it is packaged.As a result,the taste of food is also retained.

              Save Space

              Vacuum Packaged products are compact and organized,when you put them into your refrigerator or other places,they will not occupy too much space,in other word,vacuum packaging can save your space.

              Reduce Cost

              By the way,vacuum packaging can reduce the cost which you spend in packaging food or other products because its packaging procedure and raw material are simple.

              Convenient

              Similar to the last point,the whole operation process of vacuum packaging is more simple than shrink packaging,it doesn’t have so many complex procedure,so vacuum packaging is convenient.

              Cons of Vacuum Packaging

              Cons of Vacuum Packaging

              Not Environmental Friendly

              Generally,vacuum packaging uses disposable packaging pouches,which are unfriendly to the natural environment.

              Easy to be Affected by Temperature

              Although vacuum packaging can lengthen the shelf life of food,it often thanks to the help of refrigerator,if food is exposed to the high temperature condition,it still be affected.

              Not Adapt to Liquid

              There are a few kinds of liquid such as beverage and milk can be vacuum packaged,but when it comes to soup or congee,it seems not so convenient to operate.

              5.What is the application range of shrink packaging VS vacuum packaging?

              Even if both shrink packaging and vacuum packaging are suitable for many fields,they also have their own applications.

              Application Range of Shrink Packaging

              Application Range of Shrink Packaging

              Vacuum packaging applied in electronic components industry,to prevent the components from being damaged by statics.

              The all above is the main applications of shrink packaging and vacuum packaging,of course that these are not the whole application range,the applications of shrink packaging and vacuum packaging is large more common than you can image.

              6.What is the working principle of shrink packaging VS vacuum packaging?

              After reading the all above content,I believe that you have a general understand of the two packaging methods,the next part is to tell you the working principle of them.

              Working Principle of Shrink Packaging

              Working-Principle-of-Shrink-Packaging

              In detail,the working principle of shrink packaging is that,heating the shrinking film at a high temperature, the irregular arrangement of atoms has undergone drastic changes.

              Then under the use of infrared radiation light, plastic molecules move again, the arrangement changes, so that through atomic rearrangement, resulting in a large reduction of the area of the film.

              In this way, it can more closely fit the finished products to be packaged and processed by the manufacturer, that is the working principle of shrink packaging.

              Working Principle of Vacuum Packaging

              Working Principle of Vacuum Packaging

              The working principle of vacuum packaging is simple,it solves the problem from the origin.At first,you need to consider,why does food go bad?The chief culprit is microorganism,it is because of the survival of microorganism that the food would be mildewed,however,what if microorganism disappears?

              Vacuum packaging achieves this,the survival of microorganism depends on oxygen,so we extract the oxygen of the packaging pouch,means that the microorganism loose its survival condition,it can not survive and multiply,so the function of vacuum packaging is realized.

              7.What is the technologicalprocess of shrink packaging VS vacuum packaging?

              Besides the working principles,you also need to know the technological process of shrink packaging and vacuum packaging,that is,how does a shrink package or vacuum package create.

              Technological Process of Shrink Packaging

              Technological Process of Shrink Packaging

              There are two types of shrink packaging method:manual shrink packaging and mechanical shrink packaging.

              If you choose manual shrink packaging,you need to wrap the product with film by hand,and then use heater blower gun to blow hot air on the product to complete the shrink packaging process,but this method consumes too much time and energy,so it just suitable for family needs.

              On the contrary,the mechanical shrink packaging is to assist the help of shrink packing machines,process of this shrink packaging method is also simple,just divided to two steps:wrap in advance and heat shrink.

              The first step,you need to wrap the products with plastic film,and leave the necessary seam for the heat shrink step.And then is the next step,put the wrapped products on the heat shrinking equipment,when the heating starts,the film begins to shrink until it closely fit the product.

              Technological Process of Vacuum Packaging

              Technological Process of Vacuum Packaging

              Vacuum packaging needs to use vacuum packaging machines,although there are many types of vacuum packaging machines,their working process is similar.The whole packaging process can be divided into three parts:extracting out air,filling into other gases,hot-sealing.

              At the beginning,put product into the chamber of vacuum packaging machine,then the machine start work,extract the air of the packaging pouch until the vacuum index in the pouch is up to requirement.

              After this step,the machine fills other gases such as nitrogen, carbon dioxide, rare gas and other single gas or a mixture of two or three gases into the packaging pouch,to guarantee that the pouch is under the positive pressure,which makes the product hard to be damaged.

              The final step is hot-sealing,the chamber inflates and the hot pressure frame presses the mouth of packaging pouch to complete the hot-sealing operation.Until now,vacuum packaging process is finished.

              8.What are the similarities of shrink Packaging VS vacuum packaging?

              Even though shrink packaging and vacuum packaging are two different type of packaging methods,they also have some similarities,which are to the below:

              similarities

              Transparency

              In common,either shrink packaging or vacuum packaging uses transparent films or pouches to package products,this is one of their similarities.

              Heat-sealing

              During the packaging process,both shrink packaging and vacuum packaging have a heat-sealing step to ensure the products are sealed into the package.

              Neat Packaged Appearances

              Moreover,products which are shrink packaged or vacuum packaged all kept in a good and neat appearance,they looked compact,clean,exquisite and beautiful.

              Widely Used in Food Packaging

              The most similar point of shrink packaging and vacuum packaging is that both of them are widely used in food packaging field because they can make food keep fresh.

              9.What are the differences between shrink packaging and vacuum packaging?

              Certainly,when there are similarities,there are differences,now lets start to explore the differences between shrink packaging and vacuum packaging.

              differences

              Thickness of Packaging Material

              As is known,the packaging material of shrink packaging is plastic film while vacuum packaging uses packaging pouch,in many cases,the packaging pouch maybe a little thicker than plastic film.

              Packaging Machine

              It is mentioned a little bit in the previous article that the two packaging methods all have their own packaging machines:shrink packing machine and vacuum packaging machine,the two types of packaging machines have different function and working process.

              Presence of Oxygen

              The most essential difference is the presence of oxygen,shrink packaging uses high temperature to realize heat-sealing,it doesn’t affect by whether there is air,on the contrast,vacuum packaging needs low oxygen,it has a high requirement of vacuum.

              That is the most obvious distinction of shrink packaging and vacuum packaging.

              10.Which one is better-shrink packaging or vacuum packaging?

              After reading all above text,you may find that the shrink packaging and vacuum packaging have their own advantages and disadvantages separately,you can not absolutely say which of them is better,how about just say which one is better in specific situations?

              shrink packaging or vacuum packaging

              When you need to pack liquid product,it is better to put the product in proper container and use shrink packaging cause vacuum packaging isn’t suitable for all kinds of liquid products.

              When you need to pack products which is in a large size,such as furnitures,cartons,or even larger objects,it seems hard to find packaging pouches in such a large size,in this case,shrink packaging is a better choice.

              If you need to pack products which are sensitive to high temperature,choose vacuum packaging is better,the reason is that the process of shrink packaging is in a high-temperature condition,may cause damage to this type of products.

              shrink packaging or vacuum packaging-1

              And there are some products which will release toxic substances when they are under high temperature,it is obviously you can not use shrink packaging to pack them,vacuum packaging is better in this situation.

              Of course that there are many other situations,you need to consider the real condition,choose more proper one of the shrink packaging and vacuum packaging.

              Conclusion

              Totally speaking,both shrink packaging and vacuum packaging are useful and convenient for your daily life,you can choose each of them according to your actual requirement.After reading this article,if you still have some confusions,welcome to contact us.
