The Modified Atmosphere Packaging Machine is designed to extend the shelf life of fresh food by replacing the air inside the package with a protective gas mixture. This MAP packaging machine integrates vacuum extraction, gas mixing, and heat sealing to create an optimal preservation environment for food.
Our gas-flushing packaging machine supports multiple tray sizes and can achieve 2–6 cycles per minute, depending on tray size and product type. The machine is widely used for packaging fresh meat, seafood, fruits, vegetables, ready meals, and cooked food products.
With a gas-replacement accuracy of up to 99%, this tray-sealing packaging machine effectively slows microbial growth and reduces oxidation, extending product shelf life by 2–5 times compared with traditional packaging.
Working Principle of the MAP Packaging Machine
The MAP packaging machine uses modified atmosphere packaging to preserve food freshness.
Packaging Process
Vacuum Extraction
The machine first removes the air from the tray to reduce oxygen content.
Gas Mixing and Filling
A gas mixing system injects a controlled mixture of CO₂, N₂, and O₂.
Heat Sealing
The tray is sealed with high-barrier film to maintain the gas composition inside the package.
Role of Different Gases in MAP Packing
CO₂ (Carbon Dioxide)
Inhibits bacteria and mold growth.
N₂ (Nitrogen)
Replaces oxygen and prevents package collapse.
O₂ (Oxygen)
Maintains the natural color of fresh meat and certain foods.
