By using an induction cap sealing machine, thermoplastic materials are bonded together. A capped bottle is passed beneath the induction sealer in a non-contact process to establish a hermetic cap seal. By deterring oxygen and moisture from penetrating the packing, the induction cap seals protect the contents inside and act as tamper evidence.
The seal strengthens and secures the entrance of the package in order to stop leaks. The foil liner inside the cap is heated by an electromagnetic field created by the sealing head of the aluminum foil sealer machines. The wax is melted by the heat and is absorbed into the pulp board backing, which discharges the foil from the cap.
Additionally heated, the polymer film pours onto the container’s surface. When the temperature drops, the polymer bonds with the container to produce a hermetically sealed cap. The container or its contents are not negatively impacted by this sealing procedure.
