ABSTRACT:
An improved inner sealing material, which is fitted in a cap of a container has basically a membrane layer having at least a metal layer and a reseal layer having at least an elastic sheet layer, with said membrane and reseal layers being superposed in such a way that one can be separated from the other. The topmost part of the membrane layer is formed of a release layer that is made of a mixture of an acrylic resin and a chlorinated vinyl acetate base resin and which is overlaid with an adhesive layer made of a chlorinated polypropylene base resin whereas the bottommost part of the reseal layer has a polypropylene base resin layer. The inner sealing material can be subjected to high-frequency sealing without losing the inherent capability of assuring smooth separation between the membrane and reseal layers.
