About Tray Sealing Machine for Plastic Food Trays & Boxes | Food Tray Sealer with Film Lid

A tray sealing machine presses a heated plate onto a film lid to seal it hermetically onto plastic food trays and boxes made of PET, PP or PE, giving a leak-proof, tamper-evident package that extends shelf life. It is used for ready meals, fresh meat, poultry, seafood, salads, cut fruit, dairy, bakery and prepared vegetables, with modified atmosphere packaging versions flushing the tray with a gas mix before sealing. Seal strength, easy-peel opening and anti-fog film can be matched to the product, and machines run from single-cavity manual units to multi-cavity automatic lines.

How to Choose

  • Tray material and flange size to match your PET, PP or PE trays
  • Cavity count and sealing speed for your production volume
  • Modified atmosphere or gas-flush function if you need extended shelf life
  • Seal type: easy-peel for consumers or lock seal for leak resistance
  • Sealing temperature, pressure and dwell settings plus anti-fog film options

FAQ

Q: What trays can a tray sealing machine work with?
A: It seals film lids onto plastic trays such as PET, PP, PE and CPET, as long as the tray flange is flat and the film is matched to the tray material.

Q: What is modified atmosphere packaging?
A: MAP replaces the air inside the tray with a food-grade gas mixture before sealing, which slows spoilage and extends the shelf life of fresh products.

Q: Can the lid be opened easily?
A: Yes, easy-peel film gives consumers a clean opening, while lock-seal film provides a stronger closure for leak resistance in transport.

Q: How do I choose easy-peel or lock seal?
A: Choose easy-peel for retail convenience such as salads and ready meals; choose lock seal where leakage resistance matters, for example meat, seafood or liquid products.
