MAP Packaging Trays: Extend Food Shelf Life with Modified Atmosphere Technology

MAP packaging trays are specialized trays designed for use in Modified Atmosphere Packaging (MAP), a technology that extends the shelf life of perishable foods by altering the gas composition within the packaging. These trays serve as the base for holding food products while working in conjunction with a gas-impermeable film to maintain a controlled atmosphere—typically a mixture of carbon dioxide (CO₂), nitrogen (N₂), and oxygen (O₂)—tailored to the specific food type. The modified atmosphere inhibits bacterial growth, slows oxidation, and reduces respiration in fresh produce, all of which contribute to preserving the food's freshness, color, texture, and flavor for longer periods. Constructed from high-barrier plastics such as PET (polyethylene terephthalate) or PP (polypropylene), MAP packaging trays are rigid and durable, providing physical protection to the food during handling, transportation, and display. They are available in a wide range of sizes and shapes to accommodate different food products, from small trays for individual portions of cheese or deli meats to large trays for whole chickens or bulk produce. The trays are designed to be compatible with automated MAP equipment, allowing for efficient filling, gas flushing, and sealing in high-volume production settings. Many MAP packaging trays are transparent, enabling consumers to view the product clearly, which enhances its appeal and helps in assessing quality. They may also feature raised edges to contain liquids, such as meat juices or marinades, preventing leakage and maintaining the integrity of the packaging. Manufactured from food-grade materials, these trays comply with strict safety regulations to ensure they are safe for direct contact with food. By facilitating the use of MAP technology, these trays play a crucial role in reducing food waste, improving inventory management for retailers, and providing consumers with longer-lasting food products.
