为达到PET无菌瓶轻量化的目的，对“肋骨”式加强筋、“真空板”、“五爪”瓶底等结构设计进行研究，在此基础上，设计出合理拉伸率的瓶胚，并进行吹瓶应用测试。结果表明，“肋骨”式加强筋可提高16%以上的瓶子顶压，“五爪”式的底部设计可降低17%以上的瓶底积料，“真空板”可加强瓶子的抗负压能力。对于PET-500mL轻量化无菌瓶，与旧瓶型相比，每个瓶子可减重3.0g，按年产2亿瓶计，年可节约600吨PET原料。

In order to achieve the lightweight of PET bottle,the effects of“rib”,“vacuum-plate”,“five claws”on bottle structural strength were investigated. On this basis,the reasonable tension ratio of the perform was designed,and the bottle blowing application was tested. The experimental results showed that,the bottle strength was enhanced 16% by“rib”structural design,and the material accumulation at the bottle bottom was reduced 17% by“five claws”bottom design. What's more,the ability of anti-negative pressure was strengthened by“vacuum-plate”at the middle bottle. For the aseptic light-weighted PET-500mL bottle,each bottle can be reduced 3.0g. According to an annual output of 2million bottles,600 tons of PET raw materials is saved every year.
