Problem description:
It is said that there is a layer of wax on the disposable paper cup, which will melt and release toxins after pouring hot water. It is very bad for people to use it for a long time. Is there any evidence? Which plastic one? Pour hot water will also soften, will it be toxic?
Analysis:
Do you know that?/You know what? Paper cups are divided into cold drinks and hot drinks. It is very harmful to people's health if hot drinks are often filled with cold drinks. At present, the paper cups on the market are rarely clearly marked as cold drinks or hot drinks. Therefore, if relatives and friends come at home, try to entertain them with glasses and porcelain cups.
The surface of the cold drink paper cup is treated by spraying wax or dipping wax. When the temperature is between 0℃ and 5℃, the wax is very safe, but as long as the water temperature exceeds 62℃, the wax will melt and the paper cup will absorb water and deform.
The content of impurities in molten paraffin is high, especially polycyclic aromatic hydrocarbons (PAHs), which may cause cancer and enter the human body with drinks.
. A special film will be attached to the surface of the hot drink paper cup, which is not only good in heat resistance, but also non-toxic and harmless. Therefore, it is recommended that you remember to classify when buying and using disposable paper cups.
In addition, paper cups should be stored in a ventilated, cool, dry and pollution-free space, and the shelf life should not exceed 2 years from the date of production.
