Abstract
Provided are a multilayered article and a multilayered container excelling in oxygen barrier properties, delamination resistance, and transparency. The multilayered article has a polyester resin layer and a barrier layer. The polyamide resin contained in the barrier layer includes (A) a polyamide resin derived from xylylenediamine and adipic acid, (B) a polyamide resin derived from xylylenediamine, a linear aliphatic dicarboxylic acid, and isophthalic acid, and as necessary, (C) a polyamide resin derived from hexamethylenediamine, isophthalic acid, and terephthalic acid, and (D) an aliphatic polyamide resin. In the barrier layer, a ratio of the mass of the polyamide resin (A) to the total mass of the polyamide resin (B) and the polyamide resin (C) is from 98:2 to 15:85, the total content of the polyamide resin (A) and the polyamide resin (B) is 60 mass % or more, the content of the polyamide resin (B) is from 1 to 65 mass %, and the content of the aliphatic polyamide resin (D) is from 3 to 40 mass %.
