According to Luo Fenghui, secretary general of the Xiaohe District Consumers Association, there are three types of disposable paper cups currently on the market: one is made of white cardboard, mainly used for drying things, not for water and oil; It is a waxed paper cup. Because it is soaked with wax, it is waterproof and thick. But as long as the temperature of the water in the cup exceeds 40 °C, the wax will melt, and the wax contains carcinogenic polycyclic aromatic hydrocarbons; It is a paper-plastic cup that is commonly used nowadays. It is a layer of paper on the outside, and a layer of coated paper inside. If the material used in the production is not good or the processing technology is not enough, it will produce harmful substances. In addition, some paper cup manufacturers have added a large number of fluorescent whitening agents in order to make the cup look whiter. Once these harmful substances enter the human body, they will become potential carcinogenic factors.
Luo Fenghui advised consumers to use disposable paper cups with caution. If you want to use paper cups, you should also choose thick and stiff cups, and you only need to install cold water, don't buy "three no" paper cups.
