Modified Atmosphere Packaging Tray for Food Freshness & Long Shelf Life

Modified atmosphere packaging trays, commonly referred to as MAP trays, are specialized packaging components designed to work with Modified Atmosphere Packaging (MAP) technology, which extends the shelf life of perishable foods by controlling the gas environment surrounding the product. These trays are engineered to hold food items while maintaining a precise mixture of gases—typically carbon dioxide (CO₂), nitrogen (N₂), and oxygen (O₂)—that is tailored to the specific food type, such as meats, fruits, vegetables, cheeses, or prepared meals. The modified atmosphere inhibits microbial growth, slows oxidation, and reduces respiration in fresh produce, thereby preserving the food's quality, color, texture, and flavor for significantly longer periods compared to traditional packaging. Constructed from high-barrier materials like PET (polyethylene terephthalate) or PP (polypropylene), modified atmosphere packaging trays are rigid and durable, providing physical protection to the food during transportation, handling, and display. They are often paired with a gas-impermeable film that is heat-sealed to the tray, creating an airtight seal that prevents gas exchange with the external environment, thus maintaining the integrity of the modified atmosphere. These trays come in various sizes and configurations, including flat trays for thin cuts of meat, deep trays for liquid-containing products, and compartmentalized trays for mixed foods. Many are transparent, allowing consumers to view the food clearly, which is essential for assessing freshness and quality. Modified atmosphere packaging trays are compatible with automated packaging lines, making them suitable for high-volume production in food processing facilities. They are also designed to withstand refrigerated or frozen storage conditions, as many MAP-packaged foods require cold temperatures to maximize shelf life. Manufactured from food-grade materials, these trays comply with strict food safety standards, ensuring they are safe for direct contact with food. By enabling the use of MAP technology, modified atmosphere packaging trays contribute to reducing food waste, improving supply chain efficiency, and providing consumers with access to high-quality, longer-lasting food products.
