The Induction cap sealing technology helps to form hermetic seals on the neck of the container. The seal formed is strong, flexible and can be removed easily. Induction Sealing Liners are useful in providing protection against cross-contamination and also form an effective tamper-evident layer. An Induction cap sealing Machine((also called Induction Cap Sealer or Induction Liner Sealing Machine) makes use of induction heating for the purpose of sealing caps which helps the bonding process of thermoplastic material. It includes heating electrically conducting objects; this includes use of electromagnetic induction and the heat generated in the object by eddy currents. This type of induction sealing liner has many applications. One of the most common application is sealing caps by induction method, which involves heating the inner seal and ensure the top of the plastic seal. There is no-contact method performed after the container has been filled with the product. Induction sealing liners are suitable for use on the containers which are made of PET, PVC, Polythene, Glass, and other thermoplastics. Induction Cap Sealers are also used with screw-type Snap-On, Child-resistant, and other customer closures provided that the seal is in positive contact with the neck of container. A good Induction Sealing requires a uniform neck finishing. Induction sealing liners are available in different materials for HDPE, LDPE, and PET & PP, and so on. The Induction Cap Sealing Machine operates on the principle that a conductive material i.e. Al Foil heats up when exposed to a high-frequency magnetic field, which is generated by an Induction Unit. The entire process is a non-contact without any direct heat transfer. This allows the sealable closure liner to be placed in the cap by the manufacturer. The Wad consists of a board packing material, a wax layer, aluminum foil, and a sealable film. As the container closes, the screw cap combination passes through the induction unit. As the container is placed under the induction head, the Aluminium layer starts developing heat. The wax layer starts to melt and penetrate into the board layer. The Sealing layer also melts & forms a tight seal against the lip of the container. The liner/screw cap combination provides the required pressure. When the container is opened, the board continues to remain inside the cap and it acts as a seal on further use. On the other hand, the aluminum foil is permanently sealed on the rim of the mouth of the container.
