Generally, most commercially available paper cups are made of fibrous pulp, and then the inner layer is coated with plastic film for use; therefore, the heat resistance temperature is within 100 degrees. If the cup body is thinner, the heat resistance is even less than 70 degrees. Spend.

paper cup hazards
Low-quality paper cups are made of recycled polyethylene, which will produce many harmful compounds. Almost every family and unit will prepare disposable toilet paper cups. Once one person uses it, throw it away after use, which is hygienic and convenient. Dong Jinshi, vice president of the International Food Packaging Association, pointed out that disposable paper cups are "the most unsanitary".
Expert analysis
Dong Jinshi introduced that there are generally three types of paper cups on the market. One is made of white cardboard, which is impermeable to wax. It is mainly used for dry things, which is relatively safe, but the disadvantage is that it cannot hold water and oil.
Raw material problem
In the past, the wax-coated paper cup was the most used. It was soaked in wax. It can only hold cold drinks, not oily things, because oil can dissolve wax. Wax melts at around 40°C, and wax contains carcinogenic polycyclic aromatic hydrocarbons.
Now the most commonly used is a paper-plastic cup, which is a layer of paper on the outside and a layer of coated paper on the inside, which is an inner polyethylene plastic film. Although the outer layer is paper, the inner layer of plastic film is in contact with the food, so it is controversial whether this cup is defined as a paper cup or a plastic cup. In terms of testing, both paper and plastic quality are tested.
Without wax, people may feel safe in paper-plastic cups. In fact, it has the most risk factors. The health hazards of the outer layer of paper are very prominent. If the outer layer contains water, mold will form. The paper cups are stacked together, and mold on the outside will inevitably contaminate the inside. When using paper cups, be sure to see if they become damp and moldy. Secondly, the ink printed on the outer layer has a strong irritating taste, generally the taste of the ink, and the large taste may not meet the standard. Many ink components contain benzene and toluene, and benzene is a recognized carcinogen. Countries such as the United States and Japan are using non-benzene inks, and my country is still using benzene-containing inks.
