Abstract:
An ethylene-vinyl alcohol copolymer resin composition, including: an ethylene-vinyl alcohol copolymer (A); acetic acid and/or a salt thereof (B); an aliphatic carboxylic acid (C) other than acetic acid; and an aliphatic carboxylic acid metal salt (D), wherein a metal species of the salt (D) is at least one selected from long Periodic Table 4th-period d-block elements, and wherein respective contents of the acetic acid and/or the salt thereof (B), the acid (C), and the salt (D) satisfy the following formulae (1) and (2) on a weight basis is provided. The resin composition is excellent in impact resistance and adhesive strength even without being blended with any other resin: 0.001≤(content of (D) in terms of metal ion/content of (B) in terms of acetic acid ion)≤1.30  (1)0.11≤(content of (D) in terms of metal ion/content of (C) in terms of carboxylic acid ion)≤100  (2).
