Modified Atmosphere Film

Modified atmosphere film is a kind of functional packaging material. It
achieves the preservation and protection of packaged items by regulating the
gas environment inside the package. It is widely used in the packaging fields
of food, agricultural products, and some industrial products.​
Working Principle​
Modified atmosphere film has the characteristic of selective gas permeability.
It allows different gases to pass through at specific rates. For example, it
can let gases such as oxygen, carbon dioxide, and nitrogen enter and exit the
package in a certain proportion. When packaging food, the modified atmosphere
film can adjust the internal gas composition according to the characteristics
of the packaged food. Generally, it reduces the oxygen content to inhibit the
growth and reproduction of aerobic microorganisms and the oxidation reaction of
food. It appropriately increases the carbon dioxide concentration to inhibit
the growth of bacteria and regulate the respiration of food, thus extending the
shelf life of food.
