PURPOSE: To provide a flexible laminated wrapping material which is free from the deterioration of gas barrier properties even due to severe flexing fatigue by providing a thin film of a copolymer saponification of ethylene and acetic acid as an intermediate layer and a straight-chain low density polyethylene layer as a surface layer.
CONSTITUTION: The laminated wrapping material consists of an EVOH film as an intermediate layer and a surface layer arranged on both sides, each layer being arranged through an adhesive resin layer. In this material, the surface layer is formed using a straight-chain low density polyethylene layer. The straight-chain low density polyethylene to be used is a straight chain low density polyethylene which has substantially no long-chain branch. The adhesive resin is preferably either a denatured product containing a carboxyl group of an etylene-vinyl acetate copolymer or a denatured product containing a carboxyl group of an ethylene-ethylester acrylate copolymer.
