Compared with new materials, these substandard secondary materials are even less than half the price. Some plastic bottle manufacturers use or mix them with new materials in order to reduce costs. If these plastic bottles are circulated to the packaging fields of food, medicine, etc., they will be more harmful to people if they come into direct contact with food and medicine. At the same time, he also created unfair competition for manufacturers who use new materials to produce plastic bottles. In addition, the production of these secondary materials often creates harsh environmental problems.
