POLYAMIDE-BASED RESIN FILM LAMINATE HAVING READY SLIPPERINESS

摘要

PROBLEM TO BE SOLVED: To obtain the subject laminate excellent in slipperiness even under high humidity and useful as a packaging material by providing a slippery layer having ready slipperiness and consisting essentially of a graft copolymer of a polyester with an acrylic polymer onto a polyamide-based resin film substrate. SOLUTION: This resin film laminate is obtained by using a polyamide-based resin film as a base layer, providing a layer having ready slipperiness, which is the outermost surface layer directly above the base layer and laminating at least adhesive layer and undermost sealant layer, under the base layer. The layer having ready slipperiness is constituted by using a copolymer of the polyester with the acrylic polymer as a main component and a coefficient of static friction between the layers having ready slipperiness is preferably controlled to <=0.6 at 65% humidity.
