Abstract

A resin composition can be formed into a product excellent in coloration resistance even if being subjected to a melt-forming process and the like a plurality of times and hence frequently subjected to thermal history. A product formed from the resin composition, and a multilayer structure are also provided. The resin composition contains: (A) a saponified ethylene-vinyl ester copolymer; and (B) a sorbic acid ester; wherein the sorbic acid ester (B) is present in a proportion of 0.001 to 10 ppm based on the total weight of the saponified ethylene-vinyl ester copolymer (A) and the sorbic acid ester (B).

Claims (6)

1. A resin composition comprising:

(A) a saponified ethylene-vinyl ester copolymer; and

(B) a sorbic acid ester;

wherein the sorbic acid ester (B) is a methyl sorbate, and is present in a proportion of 0.001 to 10 ppm based on a total weight of the saponified ethylene-vinyl ester copolymer (A) and the sorbic acid ester (B).

2. A product comprising the resin composition according to claim 1 .

3. A multilayer structure comprising at least one resin composition layer comprising the resin composition according to claim 1 .
