MAP Tray

What is a MAP Tray?

A MAP tray refers to a Modified Atmosphere Packaging tray used to extend the shelf life of perishable foods.
These trays are designed to hold products in a sealed environment where the air inside is replaced with a gas mixture—typically oxygen, carbon dioxide, and nitrogen.
This packaging method is widely used for fresh meat, seafood, poultry, and ready-to-eat meals.

How does a MAP tray work?

MAP trays work by maintaining a specific gas composition around the food product.
This modified atmosphere slows microbial growth and oxidation, preserving the freshness, color, and texture of food.
The tray is typically sealed with a high-barrier film to retain the internal environment until opened by the consumer.

What materials are used in MAP trays?

MAP trays are made from high-barrier materials such as PET, PP, or PS, often with multilayer structures or coatings to prevent gas permeability.
Some trays include an EVOH (Ethylene Vinyl Alcohol) layer for superior gas retention.
These materials are selected to ensure product safety, durability, and compatibility with sealing machines.

What types of food are commonly packaged in MAP trays?

MAP trays are widely used for fresh meat, poultry, fish, seafood, sausages, cheese, fresh-cut fruits, bakery items, and pre-cooked meals.
They help retailers offer extended shelf life without the use of preservatives, making them ideal for chilled food packaging.

Are MAP trays recyclable?

Many MAP trays are partially recyclable, depending on their material composition and local recycling facilities.
Single-material trays like mono-PET or mono-PP are more eco-friendly and recyclable compared to multi-layer trays.
Recyclable MAP trays are increasingly in demand as part of sustainable food packaging solutions.

What sealing films are used with MAP trays?

MAP trays are sealed with high-barrier lidding films that are puncture-resistant and gas-tight.
These films may feature anti-fog properties, easy-peel functionality, or printed branding.
Proper film selection is critical to maintaining the modified atmosphere and ensuring product visibility and convenience.

Can MAP trays be used with automated packaging machines?

Yes, MAP trays are compatible with automatic tray sealing machines and vacuum gas flush systems.
They are engineered for high-speed packaging lines, ensuring a consistent and hygienic sealing process.
This makes MAP food trays a top choice for industrial food processors and large-scale meat packers.

Are MAP trays suitable for frozen storage?

While MAP trays are primarily designed for refrigerated storage, many types are also freezer-safe.
Freezer-compatible trays are made from materials like CPET or specially formulated PP that resist cracking at low temperatures.
Always confirm material specifications before using MAP trays for frozen food packaging.

What sizes and shapes are available for MAP trays?

MAP trays come in a wide range of standard and custom sizes, including rectangular, square, and compartment-style trays.
Sizes are typically selected based on portion weight, product type, and retail shelf requirements.
Custom MAP tray packaging can be tailored to meet branding or functional goals, such as stackability or tamper-evident features.

Do MAP trays meet food safety standards?

Yes, all MAP trays used in food applications must comply with food-grade regulations such as FDA, EU 10/2011, or other national standards.
They are made in cleanroom environments and are safe for direct food contact.
Many manufacturers also provide traceability documentation and quality certifications upon request.
