摘要： An object of the present invention is to provide an EVOH-containing resin composition which has superior appearance characteristics and long-run workability in melt molding and enables occurrence of yellowing etc., in melt molding to be inhibited particularly, even in melt molding at high temperatures of, for example, no less than 260° C. Further provided is a multilayered structure molded from the composition. The present invention provides a resin composition containing (A) an ethylene-vinyl alcohol copolymer, (B) a carboxylic acid and/or a carboxylate ion, and (C) a metal ion, wherein the component (B) includes (B2) a multivalent carboxylic acid and/or a multivalent carboxylate ion, and the molar ratio (B2/C) of the multivalent carboxylic acid and the multivalent carboxylate ion (B2) to the metal ion (C) is 0.002 or greater and 2 or less.
