Two-piece type closure liner

Abstract

The present application provides a two-piece type closure liner, which includes: a backing layer, which is a cardboard or a foaming board film; a sealing laminated layer, which sequentially from top to bottom includes an electromagnetic induction heating layer and a sealing layer; a weak adhesive layer, which is located between the backing layer and the sealing laminated layer, so that a peeling strength between the backing layer and the sealing laminated layer, measured by a standard of ASTM D903, is 0.05N/15 mm or more and 2.26N/15 mm or less. By the above-mentioned two-piece type closure liner, the effect of carbon reduction and saving energy consumption can be achieved.
