Summary: | Provided is an ethylene-vinyl alcohol copolymer resin composition comprising an ethylene-vinyl alcohol copolymer (X) and a metal compound, wherein the composition satisfies the following formula (1), as an ethylene-vinyl alcohol copolymer resin composition having an excellent gas barrier property in the high humidity environment, particularly an excellent oxygen barrier property in the high humidity environment: ΔA2=A2−A2,0>0 where A2 represents the second virial coefficient when the ethylene-vinyl alcohol copolymer resin composition is subjected to static light scattering measurement using hexafluoroisopropanol as a solvent, and A2,0 represents the second virial coefficient of the ethylene-vinyl alcohol copolymer (X) in the ethylene-vinyl alcohol copolymer resin composition measured in the same manner. |
