Application of high barrier PET sheet in MAP

MAP/CAP (modified atmosphere packaging) uses packaging materials with gas barrier properties to package food. According to the actual needs of customers, a certain proportion of O2+CO2+N2, N2+CO2, O2+CO2 mixed gas is filled into the package to prevent the food from being In physics, chemistry, biology, etc., quality degradation occurs or slows down the speed of quality degradation, thereby prolonging the shelf life of food and enhancing the value of food.

MAP is widely used in the packaging of fresh foods such as meat, poultry, fish, fruits and vegetables, cooked meat products, breads and pastries and other bakery products. Foods that have passed MAP have been more and more recognized by food processing manufacturers and consumers because they better maintain the original taste, color, shape and nutrition of the food, and can achieve a longer shelf life.

The body part of the MAP box is currently widely used in blister molding after compounding of PET sheet and barrier film. High-barrier PET sheets not only have good barrier properties and can be effectively recycled and reused, but also can be mixed with ordinary PET raw materials after the barrier sheets are crushed.
