Modified Atmosphere Packaging (MAP) trays are used to package perishable food items while modifying the composition of the air inside the tray to extend the shelf life of the product. There are several types of MAP trays available in the market. Here are some commonly used ones:
- Foam MAP Trays: These trays are typically made of expanded polystyrene (EPS) foam and are commonly used for packaging meat, poultry, seafood, and produce. The foam provides insulation and helps maintain the desired modified atmosphere within the tray.
- Plastic MAP Trays: Plastic MAP trays are made of materials like polyethylene terephthalate (PET) or polypropylene (PP). They are widely used for packaging various food products, including fresh produce, deli items, bakery products, and ready-to-eat meals. Plastic trays provide good visibility and can be easily sealed to maintain the modified atmosphere.
- Aluminum MAP Trays: These trays are made of aluminum and are commonly used for packaging ready-to-eat meals, convenience foods, and bakery products. Aluminum trays offer good barrier properties, ensuring that the modified atmosphere is effectively maintained.
- Paperboard MAP Trays: Paperboard MAP trays are made from paper-based materials, often with a coating or lamination to provide moisture resistance and enhance the barrier properties. They are commonly used for packaging fruits, vegetables, salads, and other perishable food items.
- Biodegradable MAP Trays: With increasing focus on sustainability, biodegradable MAP trays are gaining popularity. These trays are made from bio-based or compostable materials such as bagasse, PLA, or other plant-based materials. They offer similar functionality to traditional MAP trays while being more environmentally friendly. Custom bagasse MAP trays are becoming one of the most popular choices or replacements for those plastics. Reducing plastic creates a green world.
It’s important to note that the availability and specific types of MAP trays may vary depending on the region and specific market. Different tray materials and designs are chosen based on the specific needs of the food products being packaged and the desired modified atmosphere requirements.
