Which cup is better, ps or pp? Healthier ...

1: The cup is indeed the most PP-PP material, and now it belongs to the safest food packaging material. Because the cocatalyst system is relatively safe and its temperature resistance is relatively high, PP products are especially suitable for food packaging. But PP cup is not as transparent as PC.

2.PC polycarbonate material has high temperature resistance and excellent transparency. If the light transmittance of PC is 100, then the light transmittance of PP is only 80. And the strength of PC material is also high. However, PC materials are easy to release a small amount of bisphenol A, and now the focus of international debate is here.

3.PC, PET, PS and other cups can make special transparent products, which is the main reason for choosing these materials in the past. The disadvantages of PET and PS are brittleness, low temperature resistance, and boiling water cannot be poured too many times.

At present, it is still recognized as PP material. PE polyethylene has good hygienic performance, but it is soft, and is mainly used for soft packaging such as film products and cosmetics.
