Paper Cups: Use Less Disposable Paper Cups

At present, almost every family and unit prepares disposable toilet paper cups, which are used by one person and thrown away after use. It is hygienic and convenient, but such a common cup hides many problems. There are three types of paper cups on the market: the first one is made of white cardboard and cannot hold water and oil. The second is a waxed paper cup. As long as the temperature of the water in it exceeds 40°C, the wax will melt and release carcinogenic polycyclic aromatic hydrocarbons. The third type is paper-plastic cups. If the selected materials are not good or the processing technology is not good enough, in the process of hot-melting or applying polyethylene to paper cups, cracking changes will occur and carcinogens will be produced. In order to increase the toughness and rigidity of the cup, plasticizers are added to the paper cup. If the amount of additives is too large or illegal plasticizers are used, hygiene will be difficult to guarantee.
