What kind of plastic cup is the safest? What kind of plastic cup is the healthiest?

1, PP material is also called (polypropylene). PP material is the safest plastic cup material at present, and PP cups are non-toxic and tasteless, with low density.

2. The processing temperature during production is 180~240℃, and the boiling water will not decompose. PP has good heat resistance, melting point 164- 170℃, and the product can be sterilized at the temperature above 100℃. It will not deform at 150℃ without external force. The brittleness temperature is -35℃. Moreover, the chemical stability of PP (polypropylene) is very good, except that it can be corroded by concentrated sulfuric acid and concentrated nitric acid, and it is relatively stable to other chemical reagents. PP is the only material that can be heated by microwave oven.
