A PET bottle refers to a plastic material called polyethylene terephthalate, or PET for short, 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 resistance to chipping, and it can also prevent carbon dioxide 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, they are very picky, easy to get started, but difficult to do. PET bottles are reprocessed by blow molding to form plastic bottles, including bottles used for packaging cosmetics, medicines, health care, beverages, mineral water, reagents, etc. This kind of bottle making method is called a two-step method, that is, a preform is formed through injection molding, and then through Blow molding process to form PET plastic bottles.
Due to its light weight, good storage properties, and the technical trend of emphasizing heat resistance and pressure resistance, PET bottles have become the mainstream of today's drinking packaging. Many beverages that require high temperature sterilization to be filled, such as flavored water, juice, dairy products, sports drinks, etc., are also packaged in PET bottles one after another.
PET bottles have become the main packaging materials for beverage products. Due to its low environmental pollution and energy consumption, PET bottles are gradually replacing traditional packaging materials in today's rising environmental awareness. With its heat-resistant, pressure-resistant functions, it has replaced various PVC bottles, bags, aluminum cans, iron cans, glass bottles, etc., and has become the packaging material with the most growth potential.
