MAP Food Trays: Extend Shelf Life with Modified Atmosphere Packaging

MAP food trays are packaging solutions that utilize Modified Atmosphere Packaging (MAP) technology to preserve the freshness and extend the shelf life of various food products. These trays are designed to create an optimal gas environment—typically a blend of carbon dioxide (CO₂), nitrogen (N₂), and oxygen (O₂)—that is tailored to the specific type of food, such as fresh produce, meats, cheeses, or baked goods. The modified atmosphere slows down the natural processes that cause spoilage, including microbial growth, oxidation, and enzymatic activity, thereby maintaining the food's quality, color, texture, and flavor for longer periods. Constructed from high-barrier plastics like PET (polyethylene terephthalate) or PP (polypropylene), MAP food trays are rigid enough to protect food from physical damage during transportation and display. They are often sealed with a transparent, gas-impermeable film that maintains the modified atmosphere while allowing consumers to view the product clearly. The trays come in various sizes and designs to accommodate different food items: small trays for berries or diced cheese, medium trays for sandwich components or sliced meats, and large trays for family-sized portions of salad or roasted vegetables. Some MAP food trays feature perforations to allow controlled gas exchange, which is particularly important for fresh produce with high respiration rates, such as leafy greens. The trays are also compatible with refrigerated or frozen storage, as cold temperatures work in conjunction with the modified atmosphere to further extend shelf life. Manufactured in hygienic conditions, MAP food trays comply with strict food safety standards, ensuring they are safe for direct contact with food. By preserving food freshness, these trays reduce waste, improve inventory management for retailers, and provide consumers with longer-lasting, high-quality food options.
