Abstract:
An ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer including two or more types of ethylene-vinyl alcohol copolymers having different ethylene structural unit contents; and (B) an iron compound; wherein the iron compound (B) 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 is substantially free from coloration and excellent in heat stability.
