Claims
- 1. A laminated material which comprises a resin having gas barrier properties and a hydrophobic termoplastic resin laminated with an adhesive resin composition comprising: (a) metal containing composition consisting of (i) an ethylene-acrylate or methacrylate copolymer containing from 5 to 45% by weight acrylate or methacrylate component content, said copolymer being grafted with 0.01 to 6% by weight of an ethylenic unsaturated carboxylic acid or its acid anhydride; and (ii) 0.02 to 0.6 equivalent of the ethylenic unsaturated carboxylic acid or its acid anhydride of a periodic table Group Ia or IIa metal hydroxide; or (b) a blend of said metal containing composition (a) with ethylene-acrylate or methacrylate copolymer wherein said metal containing composition (a) constitutes 1-60% by weight of said blend.
- 2. A laminated material according to claim 1, wherein the acrylate or methacrylate in the adhesive resin composition is ethyl acrylate or ethyl methacrylate.
- 3. A laminated material according to claim 1, wherein the ethylenic unsaturated carboxylic acid or its acid anhydride is maleic anhydride.
- 4. A laminated material according to claim 1, whrein the periodic table group Ia or IIa metal hydroxide is sodium hydroxide.
- 5. A laminated material according to claim 1, wherein the resin having gas barrier properties is a saponified ethylene-vinyl acetate copolymer resin having an ethylene component content of 20-55 mole % and a saponification degree of not less than 90%.
- 6. A laminated material according to claim 1, wherein the hydrophobic thermoplastic resin is a saturated polyester.
- 7. A laminated material according to claim 1, wherein the hydrophobic thermoplastic resin is a polycarbonate.
- 8. A laminated material according to claim 1, wherein the laminated material is a coextruded laminated material.
