METHOD FOR PRODUCING ADHESIVE LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an adhesive laminate 10, which is produced by an extrusion molding that does not use a solvent, has a few production steps, excellent molding processability and excellent economic efficiency.SOLUTION: The inflation film formation method includes forming a film using a back layer 11 of low-density polyethylene, a foam layer 13 composed of a low-density polyethylene and a chemical blowing agent and an adhesive layer 19 of an ethylene-methyl methacrylate copolymer having a melt flow rate (MFR) of 1.0-8.0 g/10 minutes and containing 10-25 mass% of a methyl methacrylate component by a multilayer coextrusion molding method and simultaneously foaming the film in an expansion ratio of 1.1-3.0 times. The adhesive layer has a total thickness of 100-500 μm and the adhesive layer is 2.0-40% of the total thickness.
