Foodline MAP packaging machine for fresh food

The automatic tray sealer machine is a type of food packaging equipment that seals products inside pre-formed trays using heat and sealing film. It is combined with Modified Atmosphere Packaging (MAP) technology to prolong shelf life, minimize spoilage, and enhance product presentation.

How Does a Tray Sealer Machine Work?

The tray sealing process generally involves these steps:

  1. Product Loading: Food items are placed into trays either manually or automatically.
  2. Vacuum or Air Removal: The machine extracts oxygen from the tray.
  3. Gas Flushing (MAP): Protective gases are introduced into the package.
  4. Heat Sealing: A top film is heat-sealed onto the tray, creating an airtight package.
  5. Output Inspection: Finished packages are examined for seal quality, gas retention, leaks and Correct label placement.
