Paper cup hazards

The use of recycled polyethylene for inferior paper cups will produce many harmful compounds. Almost every family and unit will prepare disposable toilet paper cups, which can be thrown away once used by one person. Hygienic and convenient. Dong Jinshi, vice president of the International Food Packaging Association, pointed out that disposable paper cups are "most unhygienic."

According to Dong Jinshi, there are three types of paper cups on the market. One type is made of white cardboard, which is impervious to wax. It is mainly used to dry things and is relatively safe, but the disadvantage is that it cannot hold water and oil. In the past, wax-coated paper cups were used the most. It was soaked in wax. It can only be filled with cold drinks, not oily things, because oil can dissolve wax. The wax melts at around 40°C, and the wax contains the carcinogen polycyclic aromatic hydrocarbons.
