Kind Code:
A1
Abstract:
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.
