Disposable paper cups used in daily life are not easy to bubble bad when exposed to water, the main reason is the paper cup manufacturing materials and manufacturing process.
At present, disposable paper cups on the market are generally made of two kinds of materials, one is coated with wax layer inside, which is coated with a thin layer of wax. Of course, this kind of wax is different from industrial wax and belongs to food grade wax. This kind of paper cup can only be used for cold drinks, because the wax will melt when the temperature reaches 40-50 degrees Celsius, causing water leakage and burns. Wax, even if it is food grade, is not good for you, so be sure not to misuse it.
The second is the paper cup that can hold hot drinks, which is made of PE film technology, outside is a layer of paper, inside is a layer of film, this is a polyethylene plastic film, the material is edible grade polyethylene, polyethylene is the safest chemical substance in food processing, but if the material is not good or the processing technology is not qualified, it will also produce harmful substances. So before you drink out of a paper cup, smell it for any odors.
