MANUFACTURING METHOD OF LAMINATE FILM

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a favorably tearable laminate film (having easily tearing properties) excellent in adhesion. SOLUTION: In the manufacturing method of the laminate film for pasting a heat fusible plastic film to a plastic film with an inorganic layer formed thereon applied by a laminate adhesive prepared by blending a hydroxy group-terminated polyurethane resin (A) with a polyisocyanate curing agent (B) under the mass ratio of (A):(B)=100:30 to 100:100 and then thermally curing them, (A) has a substantial average functionality of 2 and a number average molecular weight of 10,000-50,000 and (B) is an isocyanurate-modified polyisocyanate of hexamethylenediisocyanate having a substantial average functionality of 2-10.
