Multilayered article and multilayered container

Abstract

Provided are a multilayered article and a multilayered container comprehensively excelling in oxygen barrier properties, delamination resistance, and transparency. The multilayered article includes a layer containing a polyester resin as a main component and a layer containing a polyamide resin as a main component; wherein the polyamide resin included in the layer containing a polyamide resin as a main component includes from 90 to 60 parts by mass of a polyamide resin (B) per 10 to 40 parts by mass of a polyamide resin (A). The polyamide resin (A) is an aliphatic polyamide resin. The polyamide resin (B) includes a structural unit derived from a diamine and a structural unit derived from a dicarboxylic acid, 70 mol % or more of the structural unit derived from a diamine being derived from xylylenediamine, and of the structural unit derived from a dicarboxylic acid, from 30 to 65 mol % being derived from an am-linear aliphatic dicarboxylic acid having from 4 to 20 carbons, and from 70 to 35 mol % being derived from isophthalic acid, a total of which does not exceed 100 mol %.
