ABSTRACT:
Anti-gas permeation property and impact strength of a container such as a bottle which is made of polyethylene terephthalate resin by biaxially orienting blow molding are improved by using a multilayered structure of the polyethylene terephthalate and the other polyester of a dicarboxylic acid component containing a specific amount of isophthalic acid and a glycol component. The container is made preferably by preparing a preform which is a laminate of the polyethylene terephthalate and the other polyester in the molten state under pressure, and by biaxially orienting blow molding the preform.
