摘要： PURPOSE:To obtain a bottle with an excellent heat resistance and gas barrier property by setting the density of a bottle body part not less than the specific value, which comprises a polyester resin composite compounded with polyethylene terephthalate having a specific wet.% and liquid crystal polyester, and obtained by performing a biaxial oriented blow mold. CONSTITUTION:A polyester resin composite is formed by compounding polyester terephthalate 95-99.5wt.% and liquid crystal polyester 5-0.5wt.%. Herein, the liquid crystal polyester is of polyester which is obtained by polymerizing P-hydroxybenzoic acid and/or ester-formation derivative thereof, and 6- hydroxy-2-naphthoic acid and/or ester-formation derivative thereof. Upon forming the bottle comprising polyester resin composite, the bottle with 1.375g/cm more in its body density obtained performing a biaxial oriented blow mold is formed by the use of blow molds kept not less than the glass transition temperature of polyethylene terephthalate.
