It is a colorless and translucent thermoplastic lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high-wear-resistant processing properties, etc., this has made polypropylene rapidly available in machinery, automobiles, electronics, construction, textiles, and packaging since its inception. , Agriculture, forestry, fishery and food industry have been widely developed and applied.

Polypropylene material is also widely used in the water cup industry, because of its "chemical resistance" and "heat resistance" and other characteristics, it has become a more suitable material for plastic water cups. The Shangtai plastic cup made of polypropylene has a transparent body and bright color. It will not deform when poured into hot water, and it is non-toxic and harmless.
