HS (HEAT SEAL)

Induction sealing is a no contact heating process that accomplishes the hermetic sealing of a container with a closure that includes a heat-sealable foil laminate. The typical induction innerseal begins as a multi-laminate liner inside a closure. It consists of a polymer that is compatible with the bottle material and capable of heat-sealing to the lip of the container when the closure is placed onto the container and is passed through a heat source - usually an electromagnetic field produced by an induction heater.
