What material is good for plastic water bottles?

1.PP material
PP is polypropylene with a high melting point of 167°C and is the only plastic that can be put in a microwave oven and can be reused after careful cleaning. The cup made of PP has good heat resistance and stable chemical properties. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is relatively stable to other chemical reagents.
At present, bisphenol A is only found in PC material, but not in PP material. Of course, this is not to say how good PP plastic water cups are, because some relevant institutions have detected that PP plastic water cups will The release of bisphenol S at high temperatures is similar to that of bisphenol A, but as long as it is not used at high temperatures, there will be no problem.

2.Tritan material
The safest plastic cup material is Tritan material. It is the formula material for baby products in Europe and the United States. It not only does not contain bisphenol A and bisphenol S, but also does not contain any bisphenols. It can be said to be the safest at present. Plastic material.
