ABSTRACT:
An inner seal for sealing containers by heat induction, especially when the inner seal may be in contact with the contents of the container during sealing. The inner seal includes a metallic foil layer which heats up almost instantaneously, and a foam layer which thermally insulates the foil layer from the contents of the container which may be in contact with the inner seal. The foam layer is compressed, and is consequently a poorer thermal insulator, where it contacts the land area of the neck of the container to which it is being sealed.
