Automatic Induction Sealing Machine

The process of Induction Cap Sealing is based on the principle that a conductive material i.e. Al Foil heats up on exposure to high frequency magenetic field generated by an Induction Unit. This is a non contact process without direct heat transfer.Due to this, the sealable closure liner can be placed in the cap by the manufacturer. The Wad consists of a board packing material, a wax layer, aluminium foil and a sealable film. The screw cap combination passes through the induction unit after closure of the container.when the container is under the induction head, heat is developed into the aluminmium layer.The wax layer starts to melt and penetrates into the board layer.The Sealing layer also melt & forms a tight seal against the lip of container. The necessary pressure is provided by the liner/screw cap combination.On opening the container, the board remains inside the cap and serves as a seal on further use, whereas the aluminium foil is permanently sealed on the rim of the mouth of container.

Innerseal can be used on containers made of PET,PVC,Polythene,Glass and other thermoplastics.They are suitable for use with screw type Snap On,Child resistant and other customer closures as long as the seal is in positive contact with the neck of container. A uniform neck finishing is required for good Induction Sealing.The sealing are not to be very wide.The small 50 ml to the big 200.Its Drum having a neck size of 10 mm opening to the wide mouth of 120 mm can be Induction sealed.Induction Sealing liners for HDPE,LDPE,PET & PP in the different thickness locally available
