PP plastic bottles have a longer recycling time than PET bottles

Mar 23,2023


This year, 0.1% -0.4% sorbitol xylene nucleating agent has been added to general PP, and high-pass PP plastic packaging bottles can be produced by blowing, pulling, injection, kneading and other methods. PP plastic bottles have good temperature resistance, sensitive bottle shape, excellent performance in safety, hygiene and consistency of contents, and the price is cheaper than PET, PS, PE and other materials.

The use scale of PP plastic bottles in the beverage packaging market has gradually approached that of PET bottles. The continuous development of modified resins, anti-transparency agents and mechanical equipment skills has enabled PP containers to replace glass, PET and PVC containers, and have broad market prospects. PET bottles are the main stream of beverage packaging. PET sliced particles should dominate the beverage packaging industry in China. So far, no better or better packaging materials have been found to replace PET.

PP bottles are mainly molded in one-step injection, pull-blowing and two-step heating, pull-blowing molding machines. PP bottles have the advantages of transparency, robustness and heat resistance, and the price is lower than that of traditional materials. It can be stored at 100 ° C for hot filling, while the general PET bottle filling temperature cannot be higher than 76 ° C of glass transition. PP has about 5 times the moisture isolation function of PET, and the production equipment of PP preforms is lower than that of PET preforms. PP plastic bottles have a longer recycling time than PET bottles.
