An Induction Sealer Machine is used to hermetically seal the opening of a container, typically made of plastic or glass, with an aluminum foil liner. The process is non-contact and uses electromagnetic induction to generate heat in the foil, which melts the sealant layer of the liner, bonding it to the container’s rim. This creates a tamper-evident, airtight seal that helps protect the product from contamination, preserve freshness, and prevent leaks. Induction sealing is widely used in industries like food and beverage, pharmaceuticals, cosmetics, and chemicals.
