Abstract

An ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) a styrene derivative; and (C) an iron compound; wherein the iron compound (C) is present in an amount of 0.01 to 5 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition. The ethylene-vinyl alcohol copolymer composition has ultraviolet absorbability even without a known ultraviolet-absorbing agent blended therein, and is excellent in heat stability and reduced susceptibility to coloration.
