Flasche aus Polyester und Verfahren zur Entfernung von sich auf der Flasche befindenden Stoffe |
摘要 |
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 to 150 DEG C or bringing the bottle into contact with water or water vapor heated at 40 to 150 DEG C. |
