Food grade PP+PC plastic cups are safe, and there is no problem in drinking water. 1. Both PC and PP can be used as food grade plastics. Many people say that only PP is food grade, which is a conceptual issue. Food grade refers to the relevant certification. For example, it is FDA in the United States, and other European Union and Japan also have certification, but it is the FDA that has the widest applicability. Therefore, it cannot be proved that PP is more healthy from this angle. There are many products of both
2. The harm of PC comes from BPA, that is, bisphenol A. This problem is well known. The harm of bisphenol A is not as great as the legend. The completed animal experiments have also proved that the harm is aimed at the development stage, and there is no need to alarmist. Therefore, the pregnant and young groups should pay due attention. The reason for this is because the opportunity to contact bisphenol A is not the same occasion, In addition, the dose of animal experiment is very large, and the trace bisphenol A in PC plastic can be carried by our human body
3. PP is not absolutely safe, and PP from suspicious sources is much more harmful than PC from regular channels. Many PP plastic products on the market use recycled materials, and the worst hit areas use straws and disposable products. In addition, PP also uses catalysts in the production process, which generally contain titanium and aluminum
4. PC has excellent performance and is an important class of engineering plastics. It has good resistance to temperature. There is no problem that it cannot be filled with hot water. PP has average performance, but there is no problem in filling hot water
5. Ceramics and glass are safer than plastics, which is also based on the reliable source. Some porcelain clay or glaze contain heavy metals, and will precipitate because the firing process is not up to standard. This does not mean that plastics are good, but that there are deficiencies in any material, which cannot be generalized. The same is true of the relationship between PC and PP.
