COEXTRUDED MULTILAYER FILM AND LAMINATED FILM USING THE FILM

摘要

PROBLEM TO BE SOLVED: To provide a coextruded multilayer film which can be used as sealant film for a pillow packaging bag, has easy openability to be opened easily by hand, and has enough sealability even when used for gas packing packaging and a laminated film using the film.;SOLUTION: The coextruded multilayer film in which a surface layer A, an intermediate layer B, and a seal layer C are laminated in turn i.e. A/B/C is constituted. The intermediate layer is a resin layer comprising low density polyethylene b1 and an ethylene/α-olefin copolymer b2. The seal layer C is a resin layer comprising a propylene/α-olefin copolymer c1 produced by using a metallocene catalyst and linear low density polyethylene c2.;COPYRIGHT: (C)2007,JPO&INPIT
