Abstract
The present invention relates to a resin composition having gas barrier properties, which has excellent low-temperature characteristics and resistance to hydrogen brittleness without greatly detracting from gas barrier properties, and which can contribute to improve durability when used as a resin tube for high-pressure gas or as a resin liner for a composite container. Provided is an EVOH resin composition comprising: a fluororesin (A) having a functional group capable of interacting, or reacting, with a hydroxyl group; a thermoplastic resin (B) having a carboxyl group or an acid anhydride group (however, the fluororesin (A) and a saponified ethylene-vinyl ester copolymer (EVOH) having a carboxyl group or an acid anhydride group are excluded); and an EVOH (C).
