Abstract
A resin composition includes: an ethylene-vinyl ester copolymer saponified product (A); and fatty acid metal salts, wherein the fatty acid metal salts include at least two fatty acid metal salts selected from a fatty acid metal salt having 3 to 12 carbon atoms (B), a fatty acid metal salt having 13 to 20 carbon atoms (C), and a fatty acid metal salt having 21 to 29 carbon atoms (D), and wherein at least one of the fatty acid metal salts selected from the fatty acid metal salts (B), (C), and (D) includes a zinc salt. The resulting resin composition is capable of forming a multilayer structure that has suppressed occurrence of appearance failure and minimized color tone deterioration at the time of its melt molding.

A resin composition, comprising:
- an ethylene-vinyl ester copolymer saponified product (A),
- fatty acid metal salts, and
- optionally, an antioxidant (H),
- wherein the fatty acid metal salts comprise at least two fatty acid metal salts selected from the group consisting of
- a fatty acid metal salt having 3 to 12 carbon atoms (B),
- a fatty acid metal salt having 13 to 20 carbon atoms (C), and
- a fatty acid metal salt having 21 to 29 carbon atoms (D),
- wherein the at least two fatty acid metal salts selected from the fatty acid metal salts (B), (C), and (D) comprise a zinc salt,
- wherein a total content of the zinc salt is from 0.0005 parts by weight to 0.03 parts by weight with respect to 100 parts by weight of the ethylene-vinyl ester copolymer saponified product (A) in terms of metal, and
- wherein, if the antioxidant is contained, the antioxidant (H) is contained in an amount of less than 0.008% by weight based on the resin composition.
