Abstract

The present invention provides a resin composition having a high level of processability, which is a resin composition including a saponified ethylene-vinyl ester-based copolymer (A), a layered inorganic compound (B), and a carbonic acid salt (C) (provided that the carbonic acid salt (C) excludes the layered inorganic compound (B)).

First claim

The invention claimed is:

1. A resin composition comprising: a saponified ethylene-vinyl ester-based copolymer (A), a layered inorganic compound (B), and a carbonic acid salt (C), provided that the carbonic acid salt (C) excludes the layered inorganic compound (B),
wherein the content of the carbonic acid salt (C) is, in terms of metal of the carbonic acid salt (C), from 10 to 1,000 ppm relative to the total amount of the saponified ethylene-vinyl ester-based copolymer (A) and the layered inorganic compound (B).

2. The resin composition according to claim 1 , wherein the weight ratio of the carbonic acid salt (C) to the layered inorganic compound (B) is from 0.001 to 0.3, with respect to (C)/(B).

3. A molding material comprising the resin composition according to claim 1 .

4. A multilayer structure comprising a layer comprising the resin composition according to claim 1 .
