Abstract

An ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) a long Periodic Table 4th-period d-block metal compound; 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 exhibits improved impact resistance and heat stability (color tone deterioration-suppressing effect and coloration-suppressing effect).
