摘要 |
A blown plastic container of a type normally blown from a single resin preform, such as PET, wherein the bases of a three layer construction with at least one layer either being PET having a high IV or a resin which has a high Tg. The secondary resin may either be in the form of a core layer injected into the base of the injection molded preform or in the form of initially injected inner and outer base layers. By utilizing a small amount of the second resin, greater strength can be obtained together with a greater resistance to cracking at higher temperatures as well as the reduction in the overall weight of the resultant container. |
