Abstract
An ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an alkali earth metal compound; and (C) a sorbic acid ester; wherein the sorbic acid ester (C) is present in an amount of 0.00001 to 10 ppm based on the weight of the ethylene-vinyl alcohol copolymer composition; wherein the ratio (B)/(C) of the weight of the alkali earth metal compound (B) on a metal basis to the weight of the sorbic acid ester (C) is 10 to 30,000. The ethylene-vinyl alcohol copolymer composition is less susceptible to coloration.
