The first cup of disposable paper cup is the most deadly! Disposable paper cups look hygienic and convenient, in fact, the product qualification rate cannot be judged. Some paper cup manufacturers add a large amount of fluorescent whitening agent to make the cup look whiter, and this fluorescent substance can cause the cells to mutate and enter the human body, which becomes a potential carcinogenic factor.
In addition, the inner wall of the disposable paper cup is often coated with a layer of wax. If the water temperature exceeds 40 ° C, the wax will melt. If you unfortunately encounter a paper cup made of industrial paraffin coating by the unscrupulous manufacturer, this harmful substance enters the body, the human nervous system and the hematopoietic system. Both will be seriously damaged! Therefore, do not use a disposable paper cup to drink water. If there is no way, it is recommended not to drink the first cup of water in a disposable paper cup. After four or five minutes, the water is poured off to make the harmful substances volatilize.

The colorless glazed embossed ceramic mug cup is the safest. Drinking water is preferred to ceramic cups painted without color glaze, especially if the inner wall is colorless. Not only material safety, high temperature resistance, but also relatively good insulation effect, drinking hot water or drinking tea is a good choice.

The glass is the healthiest. The glass mugdoes not contain organic chemicals during the firing process.
