Disposable Cup Process

At present, almost every family and unit will prepare disposable cups, which can be thrown away once used by one person. 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 contain water and oil.

The second is a wax-coated paper cup. As long as the water temperature exceeds 40°C, the wax will melt, releasing the carcinogenic polycyclic aromatic hydrocarbons. The third type is paper-plastic cups. If the selected materials are not good or the processing technology is not enough, the process of hot-melting or applying polyethylene to the paper cups will cause cracking changes and produce carcinogens. In order to increase the toughness and rigidity of the cup, the paper cup will add plasticizer. If the dosage is too large or illegal plasticizers are used, the hygienic condition is difficult to guarantee.
