Induction Heat Sealing

Induction heat sealing is now used extensively in the packaging industry. It involves one-step heat sealing, either continuous heat sealing before encapsulation or static heat sealing before encapsulation. Several types of systems can be used. An example of induction heat sealing is its use in the food and pharmaceutical industries for cap sealing containers. A layer of aluminum foil is placed over the bottle or jar opening and heated by induction to fuse it to the container. This provides a tamper-resistant seal, since altering the contents requires breaking the foil.
