Professor Yang of Polymer Materials Science, Linyi Normal University, Shandong Province, said that qualified beverage bottles and mineral water bottles are required to be made of food grade plastics, ie PET bottles, but these food grade PET bottles cannot withstand high temperatures and need to be used at low temperatures. It is safe to use below 70 degrees Celsius. When the consumer repeatedly uses the bottle, there is no hygienic procedure, and the bacteria may repeatedly multiply in the bottle. Professor Yang reminded that the triangular symbol of the bottom of the plastic bottle is a plastic recycling mark, which is usually marked with numbers, each of which represents a different material. The bigger the number, the safer it is. If the number is 5 or higher, it means that the plastic bottle can be recycled. If it is less than 5 or even no number, it can no longer be used. On the 10th, the reporter visited several supermarkets in Linyi City and found that the bottom of the mineral water bottle on the market basically has the number "1" mark. The number "2" is visible on the bottom of most yogurt. In addition, some plastic water bottles do not clearly mark the high temperature and low temperature range, and the bottom of the plastic water bottle is usually covered by a large trademark, and the plastic material is not visible at all. The horse who is giving the bottle to the child said that he does not know that there is a sign on the bottom of the plastic bottle. When purchasing, he will only pay attention to the appearance and price. The reporter learned in the interview that many consumers still have many misunderstandings when using plastic catering products. Experts suggest that the number at the bottom of plastic catering products should be recognized and used separately. Ms. Wang, a citizen of Linyi, Shandong, told the reporter that the bottle of juice that the son had finished drinking juice would often be used to hold water when going out. The heat of the bottle would not be deformed, which was convenient and “hygienicâ€. Ms. Wang said she was unaware of the safety hazards of recycling plastic bottles.
