¿What is heat sealing?

Heat sealing is the process in which the trays are sealed by applying heat and pressure, thus allowing them to be completely sealed and avoiding air and liquid leaks.

The tray sealers machines are used to heat seal food in trays.

There are different heat sealing systems depending on the product to be packaged: conventional heat sealing, gas flushing system heat sealing, heat sealing with vacuum and gas (MAP - Modified Atmosphere Packaging), heat sealing with Skin Pack ISO ( in trays) and Skin up heat sealing (flat cartons).
