ABSTRACT:
A laminated cap liner that, when subjected to an induction heating cap sealing process, can simultaneously release a container sealing material, such as aluminum foil, for adhering to a container and render the cap leak-resistant through the polymerization of a settable and/or a crosslinkable adhesive composition, such as an adhesive composition including a crosslinkable ethylene-vinyl chloride copolymer, that releasably secures the container sealing material to a pulpboard backing.
