Conduction Sealing Machines
A conduction sealer uses electricity to heat the metal conduction head. When the head comes into contact with the container topped with aluminium foil, the combination of pressure and heat causes the foil to be hermetically sealed to the container.
In the process of Conduction Sealing, heated surface (platen) makes direct contact with foil seal.Its purpose is to cause the foil seal to become hot and the heat seal laminate to be activated.
Pressure, Temperature and Dwell Time are key variables to properly seal the container.
