Abstract
Abstract A hollow blow-moulded bottle-shaped container of a biaxially oriented mixture resin material comprising a poyethylene terephthalate resin and a xylene group-containing polyamide resin, wherein the mixture resin material contains 5 to 50% of xylene group-containing polyamide resin to the polyethylene terephthalate resin. In this container, inner and outer surface layers of the container are formed of the polyethylene terephthalate resin, and the intermediate layer of the container is formed of the mixture resin material. In this manner, the gas barrier property of the container can be enhanced.
