MAP Tray Modified Atmosphere Packaging EVOH packaging trays

Modified Atmosphere Packaging

Modified Atmosphere Packaging (MAP): Change the composition of the gas inside the package by means of gas replacement, that is, artificially increase or decrease the concentration index of the gas in the internal atmosphere or evacuate some gases, so that the food inside is different from the air composition. (Basic composition ratio of air: nitrogen 78%, oxygen 21%, carbon dioxide 0.031%, rare gas 0.939%, other gases and impurities 0.03%), by preventing and weakening the production of chemical or biochemical reactions in the food inside To achieve the effect of food preservation and prolong shelf life, the gas components inside the EVOH Barrier MAP Tray usually include one to three kinds. The use of high barrier Lidding film can further extend the shelf life of the package.

In addition, it should be noted that: 

1) It is impossible to achieve an absolutely anaerobic environment inside the package. 

2) Carbon dioxide has limited preservation effect on fresh food. 

3) Therefore, the actual application process of the modified atmosphere packaging scheme for fresh food often needs to be combined with the cold chain (relying on gas and low temperature environment) to achieve ideal results.

Moreover, Tipack also provides packaging machines for MAP Trays to customers.Please leave us a message or send an email to get the latest quotation and samples.
