MAP Seafood Tray: Extend Shelf Life with Modified Atmosphere Packaging

MAP seafood trays are advanced packaging solutions utilizing Modified Atmosphere Packaging (MAP) technology to preserve the freshness, quality, and shelf life of seafood products. These trays are designed to create an optimal gas environment—typically a mixture of carbon dioxide (CO₂), nitrogen (N₂), and sometimes oxygen (O₂)—that inhibits bacterial growth, slows oxidation, and prevents spoilage, which is critical for seafood due to its high perishability. Constructed from high-barrier plastics like PET (polyethylene terephthalate) or PP (polypropylene), the trays are rigid enough to protect delicate seafood such as fish fillets, shrimp, and shellfish from physical damage during transportation and display. They are sealed with a gas-impermeable film that maintains the modified atmosphere, while remaining transparent to allow consumers to view the product clearly, assessing freshness and quality. MAP seafood trays come in various sizes, from small individual portions to large family packs, with features like raised edges to contain moisture and prevent leakage of seafood juices. The gas mixture is tailored to specific seafood types: for example, oxygen is often excluded for fatty fish to prevent rancidity, while some shellfish may benefit from minimal oxygen to maintain color. Manufactured in hygienic conditions, these trays comply with strict food safety standards, ensuring that seafood remains safe for consumption. By extending shelf life by 2–3 times compared to traditional packaging, MAP seafood trays reduce waste, improve inventory management for retailers, and provide consumers with fresher, longer-lasting seafood.
