Polyester vessel for drink and process for preparation thereof |
摘要 |
In preparing the draw-blow-formed polyester vessel, the inner surface and outer surface temperatures of a starting preform are adjusted at specific levels at the preliminary heating step, and the drawing speed in the circumferential direction is adjusted at a level of at least 350 %/sec and a specific relation is established between the area draw ratios on the inner and outer surface sides at the draw-blowing step. A polyester vessel having a reduced shrinkage with time and a high pressure-resistant strength is obtained according to this process. |
