Patent ID: 11248112

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≤((D)/(C))≤30  (1)0.0005≤{(D)/[(B)/((B)+(C))]}≤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.
