Abstract
The refillable polyester bottle of the invention has a mean crystallinity of 32 to 70% at the bottle body, a methanol adsorption of 1,500 ppm or less at the same portion and a paraxylene adsorption of 300 ppm or less at the same portion. Therefore, the bottle is excellent in non-adsorptivity and heat resistance. According to the method of removing adsorbates on a polyester bottle of the invention, the adsorbates can be rapidly desorbed by holding the bottle in air of 40.degree. to 150.degree. C. or bringing the bottle into contact with water or water vapor heated at 40.degree. to 150.degree. C.
