2022-07-30 15:45

PET bottle refers to a plastic material called polyethylene terephthalate (PET) contained in the bottle, which is a polymer produced by the combination of terephthalic acid and ethylene glycol. PET plastic has the characteristics of light weight, high transparency, impact resistance and not easy to break. It can also prevent carbon dioxide gas and keep the steam water "gas".


PET bottles have strong applicability and are widely used in daily necessities, daily chemical packaging and other fields. From mold processing to machinery and equipment, it is very picky, easy to get started and difficult to do precision.


Due to its light weight, good preservation, and the technical trend of emphasizing heat resistance, pressure resistance and other functions, PET bottles have become the mainstream of today's drinking packaging. Many beverages that need high-temperature sterilization to be filled, such as flavored water, fruit juice, dairy products, sports drinks, etc., have also been packaged in PET bottles, and PET bottles have become the main packaging materials of beverage products. Due to its low environmental pollution and energy consumption, PET bottles are gradually replacing traditional packaging materials in today's environment-friendly society. With its heat-resistant and pressure resistant functions, it has become the packaging material with the greatest growth potential, replacing all PVC bottles, bags, aluminum cans, iron cans, glass bottles, etc.


PET bottles are re processed by blow molding to form plastic bottles, including bottles used for packaging cosmetics, medicine, health care, beverages, mineral water, reagents, etc. this bottle making method is called two-step method, that is, the method of forming preforms by injection molding and forming PET plastic bottles by blow molding again.
