<P>PROBLEM TO BE SOLVED: To provide a multilayer structure excellent in gas barrier performance even after being applied with hot-water treatment, and to provide a resin composition which can suppress an increase of viscosity at the time of melting and mixing. <P>SOLUTION: The resin composition contains (A) a saponified product of an ethylene-vinylester copolymer, and (B) a complete dehydration product or a partial dehydration product of polyvalent metal hydrosulfate hydrate. It is preferable that the (B) component is a complete dehydration product or a partial dehydration product of divalent metal hydrosulfate hydrate. At the manufacturing of the resin composition, and even at the manufacturing of the multilayer structure, an increase of the viscosity is suppressed, and stable manufacturing is enabled. After being applied with the hot-water treatment, particularly even after retort treatment, the obtained molded product is high in the speed of the recovery of the gas barrier performance, and also the excellent gas barrier performance can be maintained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
