Black PP Modified Atmosphere Packaging Tray

Modified atmosphere packaging (or inflatable packaging) is to seal meat food in a changed gas environment with gas barrier materials, thereby inhibiting the growth, reproduction and biochemical activity of spoilage microorganisms and extending the shelf life. The gases used in MAP Trays are usually carbon dioxide, oxygen and nitrogen, or various combinations thereof. The three gases must be maintained in the proper ratio to keep the meat for a long time. The preservation effect of each gas on fresh meat is as follows:
     (1) Oxygen can maintain the bright color of the muscles, and the oxygen in the mixed gas is generally more than 50% to keep the meat bright red.
     (2) Carbon dioxide is colorless and odorless, and its main function in inflatable packaging is to inhibit bacteria. It has a certain inhibitory effect on the oxidative rancidity and mold growth of meat.
     (3) Nitrogen is generally used in inflatable packaging, with stable properties and no effect on the color and microorganisms of meat. It is mainly used as a filler.

MAP Trays, Fresh Meat MAP Tray, and MAP PP Tray are all packaging solutions used in the food industry to preserve the freshness and quality of perishable products such as meat, fish, fruits, and vegetables.

MAP (Modified Atmosphere Packaging) Trays: These trays are made of materials such as PET, PP, or PS, and are designed to modify the atmosphere around the product. The packaging process involves the removal of air from the tray and replacing it with a gas mixture that is tailored to the specific product. The modified atmosphere can help extend the shelf life of the product by slowing down microbial growth, oxidation, and other deterioration processes.

Fresh Meat MAP Tray: This type of MAP tray is specifically designed for packaging fresh meat products. The trays are typically made of PET or PP, and the gas mixture used in the packaging process is tailored to the specific meat product. Fresh Meat MAP Trays help preserve the color, texture, and flavor of the meat, while also extending its shelf life.

MAP PP Tray: This type of MAP tray is made of polypropylene (PP) and is commonly used for packaging a wide range of food products, including meat, fish, fruits, and vegetables. The packaging process involves removing air from the tray and replacing it with a gas mixture that is tailored to the specific product. MAP PP Trays are lightweight, durable, and can be easily stacked and transported, making them a popular choice for the food industry.
