Food Packaging Blister PP Plastic Tray

PP MAP tray is a type of packaging tray that is commonly used in the food industry to extend the shelf life of fresh food products. The acronym "PP MAP" stands for "Polypropylene Modified Atmosphere Packaging". PP MAP Trays are made of polypropylene, which is a thermoplastic polymer known for its durability, strength, and resistance to moisture and chemicals.

The modified atmosphere packaging (MAP) technology involves modifying the air inside the packaging to create an optimal environment for the food product. This is done by using gas barriers, such as the polypropylene material in PP MAP trays, to create a controlled atmosphere. The atmosphere inside the MAP PP Tray is then modified by adjusting the gas composition, usually with a mixture of nitrogen, oxygen, and carbon dioxide. This helps to slow down the growth of bacteria and other microorganisms that can cause spoilage.

Fresh Meat MAP Tray is commonly used to package fresh meat, poultry, seafood, fruits, and vegetables. They are designed to maintain the quality and freshness of the product, extend its shelf life, and reduce food waste. The EVOH Barrier PP Trays are also transparent, which allows consumers to easily see the product inside.

Overall, PP MAP trays are an effective packaging solution for fresh food products that require a controlled atmosphere to maintain their quality and freshness.

Study on Preservation Technology of Pork Modified Atmosphere Packaging

In this experiment, the fresh-keeping technology of pork modified atmosphere packaging was studied under the condition of -2℃ micro-freezing. The results showed that: in the range of 40% concentration, the higher the concentration of CO2, the more obvious the antibacterial effect, but CO2 will also make the meat sour and produce unnatural brown color; 02 can make the pork appear bright red, but it will also accelerate Corruption; through the C02 and O2: combined test results, it is determined that the gas ratio of modified atmosphere packaging for pork under slightly frozen conditions is 40% C02 + 60% O2, and its fresh-keeping period can reach 24 days.

The effect of packaging materials on the fresh-keeping effect of pork slightly frozen modified atmosphere packaging In this experiment, the effects of different barrier properties of packaging materials on the fresh-keeping effect of pork were studied under the conditions of -2℃ slightly frozen and 40%CO2+60%O2 modified atmosphere packaging. The results show that the PET/CPE packaging bags with medium barrier properties have a good preservation effect, and the preservation period can reach 27 days, followed by PE/PA/EVOH/PA/MPE packaging bags with high barrier properties, and PA, ff'E with low barrier properties. The preservation effect of the packaging bag is very poor.
Based on the above research results, a good process for the preservation of pork micro-freezing modified atmosphere packaging is: use medium barrier PET/CPE packaging bags for modified atmosphere packaging, the gas ratio is 60% 02 + 40% C02, and directly put in after the packaging is completed. Store at -2°C in a slightly frozen condition.
