Multilayer laminate film

摘要

A multilayer laminate film comprising (A) a first layer comprising a propylene polymer and oriented in at least one direction, (B) a second layer comprising a propylene copolymer having a melting point lower than the melting point of the propylene polymer of the first layer, (C) a third layer comprising a polymer composition comprising a graft modified olefin polymer in which an unsaturated carboxylic acid or a derivative thereof is grafted, and (D) a fourth layer comprising an ethylene vinyl alcohol copolymer, these four layers being laminated in the above order. The above multilayer laminate exhibits excellent interlaminar adhesion and has excellent heat resistance.
