Foodline Modified Atmosphere Packaging Machine for Sale

This machine is also called a MAP packaging machine. It packages products using trays and a top sealing film. The process involves evacuating a portion of the air from the tray, flushing it with a specific gas mixture, and finally heat-sealing the package.

The gas inside the package helps delay oxidation and slow down quality degradation. This packaging method is widely used for food products that require an extended shelf life and an attractive retail appearance.

Foodline offers various types of MAP food packaging machines:

• 2-tray MAP machine – packs 2 trays in one cycle
• 4-tray MAP machine – packs 4 trays in one cycle

We also provide continuous and rotary MAP packaging machines for different production setups.

Working Principle of Food MAP Packaging Machine

The basic process is:

Place Food in Tray → Remove Air → Fill Protective Gas → Heat Seal → Output Packed Tray

This map packing machine first reduces the air inside the tray and then injects a specific gas or gas mixture. Common gases include:

• Nitrogen (N₂): Reduces oxygen content; suitable for meat, nuts, snacks, and other foods.
• Carbon Dioxide (CO₂): Helps inhibit the growth of certain microorganisms; commonly used for packaging meat and other foods.
• Oxygen (O₂): Used in some fresh meat products to maintain a bright red color.

The gas mixture ratio depends on the food type, packaging materials, and desired shelf life. Food manufacturers can select the appropriate gas mixture ratio based on specific products and packaging conditions.
