  An ethylene terephthalate type polyester resin for forming containers, having an intrinsic viscosity in a range of 0.65 to 0.85 dL/g, a total content of a monohydroxyethyl terephthalate and a bishydroxyethyl terephthalate of less than 0.005% by weight, (a) a heat of fusion of not more than 50 J/g, a end temperature on melting peak on not higher than 270°C and a crystallinity of less than 0.48, or (b) an acetaldehyde concentration of 2 to 10 ppm, and satisfying at least either one of (i) a peak time of crystallization is not longer than 360 seconds and the crystallization energy (ΔH) is not less than 30 J/g in the isothermal crystallization at 210°C, or (ii) components having molecular weights of not larger than 10000 are contained in not less than 8%. The polyester resin effectively prevents the problems such as a fouling of the metal mold in forming containers or a decrease in the productivity. A decreased acetaldehyde concentration provides excellent flavor-retaining property. Further, the heat-setting and mouth portion crystallization can be efficiently conducted making it possible to produce heat-resistant containers maintaining good productivity.

  一种用于制造容器的对苯二甲酸乙二醇酯类聚酯树脂，其固有粘度范围为 0.65 至 0.85 dL/g，对苯二甲酸单羟乙基酯和对苯二甲酸双羟乙基酯的总含量小于 0.005%（按重量计），(a)熔融热不大于 50 J/g，熔融峰值的最终温度不高于 270℃，结晶度小于 0.48，或(b)乙醛浓度为 2 至 10 ppm，并至少满足以下条件之一：(i)结晶峰值时间不超过 360 秒，且在 210°C 等温结晶时结晶能 (ΔH)不低于 30 焦耳/克，或(ii)分子量不大于 10000 的成分含量不低于 8%。聚酯树脂能有效防止容器成型过程中金属模具结垢或生产率下降等问题。降低乙醛浓度可提供出色的保香性。此外，还可以有效地进行热固和口部结晶，从而可以生产出耐热容器，并保持良好的生产率。
