When you replace the air in a traditional bag with a gas or a mixture of special properties, the food in the bag will last longer and be more palatable. In addition, the quality of the food packaged in this adjusted atmosphere will also be enhanced by the action of the gas.
These gases are derived from the natural components of air, such as carbon dioxide, oxygen, nitrogen, and Shanghai Chen can meet the highest quality standards.
In general, the adjustable atmosphere package eliminates the oxygen required for the survival of bacteria and mold by replacing the air, and begins to inhibit the growth of bacteria and mold when the carbon dioxide content is as low as 20%. On the contrary, when you want to pack fresh meat and prevent it from being affected by anaerobic bacteria, you need to solve the problem by making the oxygen content as high as 70%-80%. If necessary, you can also add nitrogen as auxiliary gas.
