An adhesive resin composition useful for bonding a resin having gas barrier properties and a hydrophobic thermoplastic resin which comprises an ethylene-acrylate or methacrylate copolymer grafted with an ethylenic unsaturated carboxylic acid or its acid anhydride; and 0.02 to 0.6 equivalent to the ethylenic unsaturated carboxylic acid or its acid anhydride of a periodic table group Ia or IIa metal hydroxide, or said metal hydroxide and an ethylene-acrylate or methacrylate copolymer. A laminated material of a resin having gas barrier properties and a hydrophobic thermoplastic resin laminated with the adhesive resin composition and a resin composition comprising the adhesive resin composition, a resin having gas barrier properties and a hydrophobic thermoplastic resin are also disclosed.

Adhesive resin composition, laminated material using it and resin

There is provided a laminate structure comprising (A) a layer of saponified product of ethylene-vinyl acetate copolymer and (B) a layer of hydrophobic thermoplastic resin, with (C) a bonding interlayer placed therebetween which comprises a composition of (X) a polymer of ethylene-acrylate ester-ethylenic unsaturated carboxylic acid or anhydride thereof and (Y) a polymer of ethylene-acrylate ester. The laminate is superior in interlaminar adhesion and gas barrier properties, and is suitable for food packaging.
