How the Modified Atmosphere Packaging Machine Works
This MAP packaging equipment uses a simple three-step process. First, the machine places a filled tray inside the sealing chamber. Second, it pulls out most of the air from the tray. Third, it injects a precise blend of nitrogen, carbon dioxide, and oxygen. Finally, the machine seals the tray with a strong film. This gas mixture protects the product, slows bacterial growth, and keeps the natural color.
