A melt-formable ethylene-vinyl alcohol copolymer composition and a multilayer structure are substantially free from heat coloration. The melt-formable ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an alkali earth metal compound; and (C) an iron compound; wherein the iron compound (C) is present in an amount of 0.01 to 20 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition.

Provided are an ethylene-vinyl alcohol copolymer composition and a preparation method therefor. The composition includes an ethylene-vinyl alcohol copolymer, an alkali metal element and a carboxyl-containing material, characterized in that the carboxyl-containing material includes a mono-saturated carboxylic acid and a carboxylic acid containing a carbon-carbon double bond.
