ADHESIVE FILM AND CONTAINER MADE OF POLYESTER RESIN

摘要

PROBLEM TO BE SOLVED: To provide an adhesive film that can be easily peeled off in hot water, and a container that is made of a polyester resin and has the adhesive film attached thereto. SOLUTION: The adhesive film has a substrate layer, an adhesive layer and a release sheet successively stacked in this order. The adhesive layer contains an adhesive resin obtained by crosslinking a copolymer obtained by reacting a monomer of formula (1) and a monomer containing a carboxyl group or a sulfone group and neutralized with an alkali. The adhesive layer has a tanδof≤0.43 at 85-90°C. The release sheet has a release-treated surface having a center line average roughness of 0.8-2.5μm. COPYRIGHT: (C)2007,JPO&INPIT
