PP bottles have a longer cycle time than PET bottles. After blowing, blowing, injection, kneading, etc. The insulation function of PP against moisture is about 5 times that of PET. The production equipment of PP preforms is cheaper than the production equipment of PET preforms.
The use of PP bottles in the beverage packaging market has gradually approached PET bottles.4% of sorbitol Plastic Basins xylene nucleating agent has been added to general PP. It can be stored at 100°C for hot filling, while the filling temperature of general PET bottles cannot be higher than the glass transition of 76°C. So far, no better or better packaging material has been found to replace PET.
The PP bottle has good temperature resistance function, sensitive bottle shape description, excellent performance in safety, hygiene and taste persistence of the content, and the price is cheaper than PET, PS, PE and other materials. PP bottles are mainly molded in one-step injection stretch-blow molding machines and two-step heating stretch-blow molding machines. PET bottles are the main stream of beverage packaging.
PP bottles have the advantages of transparency, robustness, and heat resistance, and the price is lower than traditional materials.1%-0..This year, 0. The leading position in Chinese beverage packaging materials should be PET chip particles. The continuous development of modified resins, anti-reflection agents, and mechanical equipment makes PP containers able to replace glass, PET and PVC containers, and has a broad market prospect., high transparent PP packaging bottles can be produced
