In recent years, by adding 0.1% to 0.4% of sorbitol xylene nucleating agent in general PP, high clarity PP plastic packaging bottles can be produced through methods such as blow extrusion, blow stretching, injection molding, and kneading. PP plastic bottles have good heat resistance, flexible bottle shape design, and perform well in terms of safety, hygiene, and maintaining the taste of the contents. Their price is lower than that of PET, PS, PE and other materials.
In recent years, by adding 0.1% to 0.4% of sorbitol dimethyl xylene nucleating agent in general PP, high clarity PP plastic packaging bottles can be produced through methods such as blow extrusion, blow stretching, injection molding, and kneading. PP plastic bottles have good heat resistance, flexible bottle shape design, and perform well in terms of safety, hygiene, and maintaining the taste of the contents. Their price is lower than that of PET, PS, PE and other materials.
The application scale of PP plastic bottles in the beverage packaging market has gradually approached that of PET bottles. The continuous development of modified resins, light transmittance enhancers, and mechanical equipment technologies has enabled PP containers to replace glass, PET, and PVC containers, presenting broad market prospects. PET bottles are the mainstream in beverage packaging. In China's beverage packaging materials market, PET chip particles should hold a dominant position. So far, no better packaging material has been found to replace PET.
PP bottles are mainly molded in one-step injection stretch blow molding and two-step heating stretch blow molding machines. PP bottles have the advantages of transparency, strength and heat resistance, and their prices are lower than those of traditional materials. They can be filled at 100℃, while the filling temperature of general PET bottles cannot exceed the glass transition temperature of 76℃. The moisture barrier property of PP is about five times that of PET. The production equipment for PP preforms is cheaper than that for PET preforms. The recycling time of PP plastic bottles is longer than that of PET bottles.
