    摘要: A container made of synthetic resin which does not cause whitening or clouding in an unstretched portion even after long-period storage and which has excellent barrier properties. A PET bottle comprising a substrate layer made of PET and a barrier layer having a gas permeability lower than that of the substrate layer, wherein the barrier layer is made of a barrier material prepared by incorporating a polyamide containing m-xylene groups with an amorphous polyamide comprising both m-xylene isophthalamide structures and hexamethylene isophthalamide structures. A copolyamide composed of both a copolymer of m-xylenediamine and isophthalic acid and a copolymer of hexamethylenediamine and isophthalic acid is used as the amorphous polyamide. The content of the amorphous polyamide in the barrier layer is adjusted to 15 to 25 wt %.
