This question is about 7 types of plastics, and 7 types of plastics. It refers to the 7 types of recycling marks for plastic products formulated by relevant institutions in the US plastics industry. Its main function is to serve as a recycling mark for easy sorting and recycling, and does not represent the level of food safety. ???????The logo for the seven recyclable plastics is shown above. In turn, they are No. 1 PET (polyethylene terephthalate), No. 2 HDPE (high density polyethylene), No. 3 PVC (polyvinyl chloride), No. 4 (low density polyethylene), and No. 5 PP ( Polypropylene), No. 6 PS (polystyrene), No. 7 other types (mainly PC polycarbonate, PA nylon). ???????Among the seven signs, those that can be used as water cups or beverage packaging are: No. 1 (PET): mineral water bottles, soda bottles, etc. Above 70 degrees, it is easy to deform, so it cannot be used for hot water, and it can not be placed in the car to expose to the sun. In addition, after using the No. 1 bottle for 10 months, the carcinogen DEHP may be released, so try not to use it repeatedly. In particular, some frugal elderly people are used to using old mineral water bottles to pack oil or wine, and it is best to let them use glass bottles instead. No. 5 (PP): common soy milk bottles, yogurt bottles, fruit drink bottles, microwave oven lunch boxes, etc. Because the PP material can withstand a high temperature of 167 ° C, the plastic container made of No. 5 can be used in a microwave oven, and it can be cleaned and reused. Therefore, No. 5 PP plastic bottles can be used for hot water and can be used multiple times, but long-term use is not recommended. ???????No. 7 (other): PCs commonly used in other plastics can be used as water cups. Basically, the water cups and space cups sold in the mall are mainly made of PC materials. The material used by the famous American cup brand Tupperware is also PC material. PC materials are non-toxic and generally resistant to high temperatures of 130 ° C. However, the quality of PCs produced by different companies, places of origin or different brands will be different. Some PC materials may leave carcinogenic bisphenol A in the production process. Therefore, most countries now prohibit the direct use of PC materials for infant products. ??????????????????????????? ????????The higher the temperature of bisphenol A remaining in PC, the more it is released and the faster the speed. Therefore, use PC material as little as possible for boiling water. If the water cup you use is made of PC, then the following methods can reduce the risk: Do not use it with heat, and do not expose it to direct sunlight. Do not use a dishwasher or dishwasher. When using for the first time, wash with baking soda powder and warm water, and dry naturally at room temperature. It can be seen that only the bottle made by PC No. 7 can be used as a drinking cup for a long time, and in actual life, we mainly use it.
