MAP Trays for Modified Atmosphere Food Packaging | Extend Shelf Life

MAP trays, or Modified Atmosphere Packaging trays, are specialized packaging components designed to work with MAP technology to extend the shelf life of perishable foods. These trays are engineered to hold food products while creating and maintaining a controlled gas environment—typically a mixture of carbon dioxide (CO₂), nitrogen (N₂), and oxygen (O₂)—that is tailored to the specific food type. The modified atmosphere slows down spoilage by inhibiting bacterial growth, reducing oxidation, and slowing respiration in fresh produce, thereby preserving the food's freshness, color, texture, and flavor. Constructed from high-barrier materials like PET (polyethylene terephthalate) or PP (polypropylene), MAP trays are rigid and durable, providing physical protection to the food during handling, transportation, and display. They are often sealed with a gas-impermeable film that locks in the modified atmosphere, while remaining transparent to allow consumers to view the product clearly. MAP trays come in various sizes and designs, including flat trays for meats, deep trays for liquid-containing foods, and compartmentalized trays for mixed items. Many are compatible with automated packaging lines, making them suitable for high-volume production. They are also designed to withstand refrigerated or frozen storage, as cold temperatures enhance the effectiveness of the modified atmosphere. Manufactured from food-grade materials, MAP trays comply with strict safety standards, ensuring safe contact with food. By extending shelf life, MAP trays reduce food waste, improve inventory management, and provide consumers with longer-lasting, high-quality products.
