Tray sealing machines are an essential part of the food packaging industry, ensuring freshness, safety, and extended shelf life for perishable goods. These machines provide a secure seal on trays using various materials, protecting contents from contamination and leakage. Whether you’re in the food, medical, or industrial sector, understanding how tray sealing machines work and how to choose the right one is crucial.
How Tray Sealing Machines Work
Tray sealing machines operate by placing a plastic or film seal over pre-filled trays. The process generally involves:
- Tray Placement: Trays are loaded into the machine manually or automatically.
- Film Application: A film or plastic sheet is positioned over the tray.
- Heat Sealing: Heat and pressure are applied to bond the film to the tray.
- Trimming and Cutting: Excess film is cut off for a neat and secure finish.
- Cooling and Ejection: The sealed tray is cooled and then ejected from the machine.
