The PP layers provide strength and stiffness, while the EVOH layer provides a gas barrier, which helps to extend the shelf life of food products. The PE layer on the outside of the film provides a barrier against water and oil.

PP/EVOH/PP or PE food packaging is used for a variety of food products, including fresh produce, meat, poultry, seafood, and dairy products. It is also used for non-food products, such as cosmetics and toiletries.

The main advantage of PP/EVOH/PP or PE food packaging is its ability to extend the shelf life of food products. This is due to the EVOH layer, which provides a gas barrier that helps to prevent food from spoiling.

Another advantage of PP/EVOH/PP or PE food packaging is its ability to maintain the quality of food products. This is due to the PP layers, which provide strength and stiffness, and the PE layer, which provides flexibility and toughness.

PP/EVOH/PP or PE food packaging is also a sustainable option. This is because it is made from renewable resources, such as PP and PE.

Overall, PP/EVOH/PP or PE food packaging is a versatile and sustainable option for packaging food products. It offers a number of advantages, including an extended shelf life, the ability to maintain the quality of food products, and the use of renewable resources.
