Abstract
An ethylene-vinyl alcohol copolymer resin composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) an aliphatic carboxylic acid; (C) an aliphatic carboxylic acid metal salt which is a metal salt of the aliphatic carboxylic acid (B); and (D) an alkali metal compound; wherein the aliphatic carboxylic acid metal salt (C) contains a metal moiety that is at least one element selected from the group consisting of long Periodic Table 4th-period d-block elements; wherein the amounts of the aliphatic carboxylic acid (B), the aliphatic carboxylic acid metal salt (C), and the alkali metal compound (D) on a weight basis satisfy the following expressions (1) and (2):0.01≤(()/())≤30  (1)0.0005≤{()/[()/(()+())]}≤1  (2).The ethylene-vinyl alcohol copolymer resin composition is excellent in impact resistance and adhesive strength even without a resin other than an ethylene-vinyl alcohol copolymer blended therein.
