The inner wall of the disposable cup has a slightly transparent brightness, which is coated with a thin layer of wax to prevent the water in the cup from penetrating the paper.
Paper cups produced in regular factories will use food grade wax to make the inner wall coating of the paper cup. Therefore, even if the water temperature is high and the wax on the paper cup is dissolved, there is no safety problem. However, some unscrupulous processing plants use low-cost industrial paraffin to coat the inner wall of the paper cup. Industrial paraffin contains substances such as stupid and polycyclic aromatic hydrocarbons harmful to the human body, which will damage the nervous system and hematopoietic system of the human body. Frequent use of inferior paper cups for boiling water, inevitably eat harmful substances in industrial wax, leading to disease.
This paraffin. According to national standards, paraffin is a safe material that can be in contact with food. The melting point of paraffin is quite high, and the high can reach more than 200 degrees. If the hot water is said to be rumored, then you can immediately see the wax as a wax oil floating on the water with the naked eye. The more common PVC used is also very resistant to temperature and the cost is not high. It also has a very prominent feature, that is, the purity is very high, almost no chemical additives, plasticizers, bisphenol A and the like, all have nothing to do with it.
But whether it is food wax or industrial wax, our consumers are really difficult to distinguish, I do not know how to distinguish. Therefore, we can only recommend that you do not use paper cups for hot water, and it is best to use less disposable paper.
