Summary: | Provided is an ethylene-vinyl-alcohol-based copolymer resin composition that has a superior gas barrier property under a high humidity condition, in particular, an oxygen barrier property under a high humidity condition, said composition containing an ethylene-vinyl-alcohol-based copolymer (X) and a metal compound and satisfying formula (1). (1): [Delta]A2=A2-A2,0 > 0 (A2 represents the second virial coefficient when a static light-scattering measurement of the ethylene-vinyl-alcohol-based copolymer resin composition is performed by using hexafluoroisopropanol as a solvent, and A2,0 similarly represents the second virial coefficient of the ethylene-vinyl-alcohol-based copolymer (X) in the ethylene-vinyl-alcohol-based copolymer composition.). |
