For achieving advance level packaging Gas flush packaging is a handy tool that can assist you in many ways and you will get highly effective packaging.

To know everything about gas flush packaging machine you need to look into this healthy article that explains all about Gas flush packaging machine and its different technical abilities.

Gas Flush Packaging Machine

Gas Flush Packaging Machine

Gas flush packaging machine is an efficient packaging and sealing machine that is used for packaging the products through gas flush.

The unique ability of Gas flush involves injecting and removing an inert gas (carbon dioxide, nitrogen, helium etc) repeatedly in order to remove all the oxygen present inside the package.

After that process gas flush packaging machine then seals pack your package to save your products from contamination.

The gas flush packaging machine has been gaining popularity because of its efficiency and versatility. Some of the advantages of the gas flush packaging machine are discussed below.

High Efficiency

High Efficiency

High Efficiency

Efficient removal of oxygen or any other unwanted compound present inside the packaging material is very important because if they are not removed efficiently, your product has chances of getting expired or contaminated.

The packaging and sealing efficiency of the gas flush packaging machine is also very high that adds to the value of this machine.

Maintains Quality of Products

In industries such as food and pharmaceutical industry, maintenance of quality of the products in the intended shelf life is very important.

The gas flush packaging machine, through proper flushing and sealing makes sure that there is no unwanted gas present inside the package and no chance of contamination from the outside is present.

In this way, your products remain fresh and in good state of quality in their intended shelf life.

Highly Productive

Optimum Productivity

Optimum Productivity

The gas flush packaging machine is a very productive machine and can do a lot of work on its own in a very short interval of time.

This saves you time and increases your production and sales. In this way, the gas flush packaging machine increases your income.

You do not need to spend money to hire any professionals. In this way, the gas flush packaging machine saves your precious money.

Versatile Machine

The gas flush packaging machine is a very versatile device. It finds its application extensively in the food and pharmaceutical industries.

The role of gas flush packaging machine in various industries is discussed later in this article.

Easy Maintenance

The gas flush packaging machine is very easy to maintain. You have to make sure that the machine is cleaned regularly, the old and worn out parts are changed timely and the electrical supply to the machine is proper.

The gas flush packaging machine is widely and extensively used in different industries. Some of these industries are discussed below.

The Food Industry

Gas Flush Packed Food

Gas Flush Packed Food

The gas flush packaging machine finds its most common and wide application in the food industry. The reason behind this lies in the fact that the gas flush packaging machine preserves the quality of food during the intended time period.

As already discussed, the gas flush packaging machine eliminates all the oxygen or any other foreign particle present inside the packaging.

The oxygen present in the atmosphere actually play a significant role in food spoiling. It can do it in various ways such as oxidation reactions and provision of suitable conditions for microbial growth and contamination.

These reactions or processes lead to a very off flavor and a foul order of food. The gas flush packaging machine actually saves the food from all this because of its efficient operation.

Many different kinds of food products such as sea food, poultry items, meat and cheese are packed using the gas flush packaging machine.

The Pharmaceutical Industry

Gas Flush Packaging

Gas Flush Packaging

The gas flush packaging machine is also used in the pharmaceutical industry for packaging the drug products that are prone to damage due to atmospheric oxygen, moisture or microbial contamination.

The environmental damage to the drug can reduce its efficacy to such a low level that it fails to achieve minimum effective concentration in the blood. The contaminated drug also has an increased toxicity which can lead to severe side effects.  

The gas flush packaging machine saves the drug product from any damage during the intended shelf life. In this way, the efficacy and effectiveness of the drug product is conserved throughout the shelf life.

Gas Flush Packaging Machine-1

Gas Flush Packaging Machine

The gas flush packaging machine is a very simple machine and its working is not too complicated. It does an amazing job by following just a few simple steps.

First step in the working of the gas flush packaging machine is flushing off the gases (especially oxygen) present inside the package. For this purpose, of gas such as nitrogen or carbon dioxide is frequently injected in and evacuated out of the package many times.

The density of the gas used for flushing is usually greater than oxygen. This causes the forceful elimination of oxygen from the package. This step reduces the oxygen concentration inside the package to a significantly low level.

The second step involves the vacuum packaging. The gas flush packaging machine creates a vacuum inside the package and then the package is sealed.

Vacuum sealing ensures prolonged quality preservation of the products by reducing the chances of microbial growth.

These two steps briefly explain the working of the gas flush packaging machine.

Gas Flush Packaging Machine-2

Gas Flush Packaging Machine

The working of the gas flush packaging machine greatly depends upon the type of gas you are using for flushing purpose. Choosing the right gas for your intended purpose is a very crucial step. Different types of gases used in the gas flush packaging machine are discussed below.


Being a non-reactive and an inert gas, nitrogen is used in the gas flush packaging machine for eliminating the air from the package. Oxygen is the main target of nitrogen.

Nitrogen also finds its application as a filler gas for prevention of the collapse that may be caused in the packaging of the products which tends to absorb carbon dioxide.

Nitrogen (100%) is also used for preventing the oxidative rancidity in the packaging of the dry snacks.

Carbon dioxide

Carbon dioxide is the most efficient gas for inhibiting the microbial growth. Therefore, using carbon dioxide for flushing purpose can be very beneficial.

Generally, the greater the concentration of carbon dioxide used, the greater is the preservation of products inside the package. But the level of carbon dioxide must not exceed limit because it can lead to package collapse, tainting of flavor and drip loss.

The lower limit of the concentration must also be considered. For example, minimum concentration of carbon dioxide for controlling the growth of molds and bacteria must be greater than 20%. Any concentration below 20% will not do the job effectively.

Visual look of Aragon gas

The properties of argon are same as nitrogen. Argon is non-reactive, odorless, tasteless and an inert gas. The molecular weight of argon is greater than that of nitrogen.

Argon can replace nitrogen in the controlled atmosphere in various applications because of its similarity with nitrogen but a greater weight.

The solubility of argon is twice as compared to that of nitrogen. These factors make argon a preferred gas for usage with the plant products.

It is believed that argon inhibits microbial growth, harmful chemical reactions and enzymatic activities.


Surprisingly, oxygen is also sometimes used as a MAP gas. Although oxygen has destructive reactions with food that cause its spoiling but in some cases, oxygen may prove to be beneficial.

For example, oxygen can inhibit microbial growth in some vegetables and fruits. It can also maintain respiration in plant products and freshness in meat.

Carbon Monoxide

Carbon monoxide is harmful, flammable, colorless, odorless and a toxic gas. Carbon monoxide is also used in gas flushing along with carbon dioxide for increased shelf life and preservation of red meat.  

The properties of carbon monoxide that make it a worthy candidate for its use in gas flushing include its stability at higher temperature and its ability to inhibit the growth of many harmful bacteria
