Abstract
A melt-formable ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an alkali metal compound; and (C) an iron compound; wherein the weight ratio of the alkali metal compound (B) to the iron compound (C) on a metal basis is 10 to 100,000. The viscosity of the melt-formable ethylene-vinyl alcohol copolymer composition decreases with time during melt forming, rendering it excellent in long-run formability.
