What is the material of plastic bottles? Will plasticizers be produced?
The stability of PET is determined by the degree of polymerization of the material. Generally, when the temperature is less than 120 degrees centigrade, the PET material is very safe. In addition to PET, plastics often used in daily use, such as PP and PE, do not add plasticizers. The addition of plasticizer in the making of PVC, PVC as the raw material for the production of some film, plastic film, children's toys, disposable gloves and other products, plastic additives products should be more strict selection of production enterprises, shall comply with the provisions of the relevant EU and national products of environmentally friendly plastics.
At present, 90% of plastic bottles in the market are polyethylene terephthalate (PET) as a bottle body material. Professor Jiang Pingping of the school of chemical and materials engineering at Jiangnan University said that the substance in the bottled water PET generally does not contain plasticizers, which are determined by the manufacturing process of PET.
Plastic bottles are made of polyethylene or polypropylene and added a variety of organic solvents. Most of the beverage bottles are made of plastic. The two materials, polyethylene and polypropylene, are non-toxic and tasteless. They are used for filling drinks and so on. They are very safe for the human body. But once the polyethylene is subjected to high temperature or acid corrosion, it dissolves slowly and releases organic solvents, which can cause harm to the human body.
