Abstract
(EN) The present invention provides: a gas barrier resin composition which uses a starting material derived from biomass and still has high gas barrier properties and high formability equivalent to those of materials derived from fossil fuels; and a molded body, a film or sheet, a packaging material, a film or sheet for industrial uses, a heat molded container, a cup shaped container, a tray shaped container, a blow molded container, a fuel container, a bottle container, a tube, a multilayer pipe and a paper container, each of which uses the above-described gas barrier resin composition. A gas barrier resin composition that contains a saponified ethylene-vinyl ester copolymer, wherein the ethylene and the vinyl ester, which are starting materials of the saponified ethylene-vinyl ester copolymer, are derived from biomass.
(FR) La présente invention concerne : une composition de résine barrière aux gaz qui met en œuvre un matériau de départ issu de la biomasse et conservant des propriétés de barrière aux gaz élevées et une formabilité élevée équivalentes à celles de matériaux issus de combustibles fossiles ; et un corps moulé, un film ou une feuille, un matériau d'emballage, un film ou une feuille à usage industriel, un contenant moulé à chaud, un contenant cupuliforme, un contenant en forme de plateau, un contenant moulé par soufflage, un réservoir de carburant, un contenant de type bouteille, un tube, un tuyau multicouche et un contenant en papier, chacun d'eux mettant en œuvre la composition de résine barrière aux gaz décrite ci-dessus. L'invention concerne une composition de résine barrière aux gaz qui contient un copolymère d'éthylène-ester vinylique saponifié, l'éthylène et l'ester vinylique, qui sont des matériaux de départ du copolymère éthylène-ester vinylique saponifié, étant issus de la biomasse.
