Abstract of the Disclosure A system is disclosed for sealing a metal foil membrane on the end of a container such as a composite container using a rotating turret having a plurality of spindles in it with non- metal rotating heads on the splindles for pressing a closure and foil membrane against the container sealing surface and rotating the container-closure assemblies about the axis of the container as they are moved through a magnetic field produced by an induc- tion heating coil disposed at least partway around the turret. The container-closure assemblies may be moved through the magnetic field in less than one second to heat the sealing area of the foil membrane and metal foil liner in the container to the required sealing temperature while minimizing heating of the membrane beyond the area of sealing contact with the container. Either the foil membrane or container liner or both have a heat seal resin thereon which is softened or melted by the induced heata in the membrane and seals the membrane to the container when the container-closure assemblies are removed from the magnetic field.
