Food heat sealing
Heat sealing is the process by which a thermoplastic is welded to another thermoplastic or any other material that allows it through the application of pressure and heat. The direct contact method of heat sealing uses a hot sealing die or bar to apply heat to a specific contact area to seal or weld the thermoplastics together, while induction sealing uses electromagnetism to generate the heat needed for sealing. welding.
At Ródenas y Rivera we have different types of traysealers according to their sealing system and their purpose. However, all traysealers have the same purpose, to protect the food in order to carry out a safe transfer.
