EVOH MAP Tray Modified Atmosphere Packaging

EVOH Barrier MAP Tray is commonly used for packaging fresh or frozen meat, seafood, poultry, and other perishable food products. The barrier properties of the EVOH layer prevent oxygen from penetrating the packaging, thereby reducing the growth of bacteria and increasing the shelf life of the product.

EVOH Barrier PP Trays are also microwaveable and can be used in a wide range of temperatures, making them ideal for food products that require heating or cooling. They are also recyclable and have a low carbon footprint, making them an environmentally friendly packaging option.

What is 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 packaging container usually include one to three kinds. 

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.

Overall, EVOH PP MAP Trays are a cost-effective, durable, and environmentally friendly option for food packaging that provides an extended shelf life for perishable food products.
