Modified atmosphere packaging, also known as MAP packaging, replacement gas packaging, inflatable packaging, etc., is to use packaging materials with gas barrier properties to package food, and add a certain proportion of oxygen, carbon dioxide and nitrogen mixture to the packaging. PP Tray packaging prolongs the shelf life of food and improves the quality of food by preventing or slowing down the physical, chemical and biological quality of food. At the same time, EVOH Barrier PP Trays can prevent the penetration of oxygen, so that he can always control the proportion of gas inside the package. For example, Fresh Meat MAP Tray keeps fresh raw meat always bright red by adjusting the oxygen concentration in the package to maintain at 60%-80%, and the partial pressure is 32kPa. PP PE Tray can be sealed by PE, and it will be better when used with Tipack brand MAP Tray Lidding Film.
After vacuum packaging, the packaged items are subject to a certain pressure due to the unbalanced internal and external pressure, which is easy to stick to a block. Crispy and fragile foods such as fried potato chips are easy to be crushed, and irregularly shaped foods are vacuumed. Wrinkled and unsightly, food with sharp corners is easy to puncture the packaging bag. The use of modified atmosphere packaging can solve these shortcomings of vacuum packaging, so that the internal and external pressures of the packaging tend to be balanced, so as to protect the bagged food and the packaging is also beautiful.
