为保证包装产品的质量，通过对普通瓶型和加强筋瓶型PET瓶进行壁厚测定、抗压试验和跌落试验来比较瓶身结构对瓶子的抗压性能及标签完好性的影响。结果表明，加强筋瓶型的瓶子更厚，垂直抗压能力更好，对标签的保护程度优于普通瓶型的，且瓶子质量的改变不影响其性能。综上，选择加强筋瓶型的PET瓶更有利于保证包装产品的质量。In order to ensure the quality of the packaged products, through wall thickness measurement, compression test and drop test of ordinary PET bottle and reinforced PET bottle, the influences of bottle body structure on the compression performance of bottles and label integrity were compared. The results showed that the reinforced bottle was thicker, its vertical compression resistance and label protection were better than the ordinary bottle, and the change of bottle mass did not affect its performance. In conclusion, choosing reinforced PET bottle is more conductive to ensure the quality of the packaged products.
