Induction Sealer Machines

Induction sealing machines are a non-contact heating process (sealing) that welds a foil laminate (called an inner seal) to the lip of jars and bottles. It is the process of bonding thermoplastic materials by induction heating. This involves controlled heating of an electrically conducting object (usually aluminum foil) by electromagnetic induction, through heat generated in the object by eddy currents. Induction sealing is used in many types of manufacturing. In the packaging it is used for package fabrication, such as forming tubes from flexible materials, attaching plastic closures to package forms, etc. Probably the most common use of induction sealing is cap sealing, a non-contact method of heating an inner seal to hermetically seal the top of plastic and glass containers. This sealing process takes place after the container has been filled and capped.
