How induction seal works :
The closure is supplied to the bottle with an aluminum foil layer liner already inserted. Although there are various liners to choose from, a typical induction liner is multi-layered.
The top layer is a paper pulp that is generally spot-glued to the cap.
The next layer is wax that is used to bond a layer of aluminum foil to the pulp.
The bottom layer is a polymer film laminated to the foil.
After the cap or closure is applied, the container passes under an induction coil , which emits an oscillating electromagnetic field.
As the container passes under the induction coil (sealing head) the conductive aluminum foil liner begins to heat due to eddy currents. The heat melts the wax, which is absorbed into the pulp backing and releases the foil from the cap. The polymer film also heats and flows onto the lip of the container.
When cooled, the polymer creates a bond with the container resulting in a hermetically sealed product. Neither the container nor its contents are negatively affected; The heat generated does not harm the contents.
Benefits of induction vs. conduction sealing
Conduction sealing requires a hard metal plate to make perfect contact with the container being sealed. Conduction sealing systems delay production time because of required system warm-up time. They also have complex temperature sensors and heaters.
Unlike conduction sealing systems, induction sealing systems require very little power resources, deliver instant startup time, and have a sealing head which can conform to “out of specification” containers when sealing.
Induction sealing also offers advantages when sealing to glass: Using a conduction sealer to seal a simple foil structure to glass gives no tolerance or compressibility to allow for any irregularity in the glass surface finish. With an induction sealer, the contact face can be of a compressible material, ensuring a perfect bond each time
