The harm of paper cups

At present, the quality of disposable paper cups on the market is uneven, the hidden danger is greater. Some makers of paper cups add fluorescent brighteners to make them look whiter. The fluorescent substances cause cells to mutate and become potentially carcinogenic once they enter the body. In order to make the cup water-proof, the inside of the cup is coated with a polyethylene water-proof film. Polyethylene is the safest chemical in food processing, but if the material chosen is not good or the processing technology is not up to standard, carbonyl compounds may be oxidized during the melting or coating of polyethylene into a paper cup, and carbonyl compounds do not volatilize easily at room temperature, but may evaporate when a paper cup is filled with hot water, so people can smell it. Although there are no studies to confirm the carbonyl compounds released from paper cups will bring about any harm to the human body, but from the general theory analysis, long-term intake of this organic compounds, it must be harmful to the human body. More worrying is that some poor-quality paper cups using recycled polyethylene, in the reprocessing process will have cracking changes, resulting in a number of harmful compounds, in the use of water migration more easily. The state explicitly prohibits the use of regenerated polyethylene in food packaging, but because of its low price, some small factories to save costs, still use illegal.

In order to achieve the paper cup in the production of water-resistant effect, will be coated with a layer of polyethylene water-resistant film on the inner wall. Polyethylene is a relatively safe chemical in food processing, it is difficult to dissolve in water, non-toxic, tasteless. But if the selected material is not good, or processing technology, in the polyethylene hot melt or coating into the cup process, may be oxidized to carbonyl compounds. Carbonyl compounds don’t evaporate easily at room temperature, but they do when paper cups are filled with hot water, so people smell funny. Long-term ingestion of this organic compound is harmful to health. Some low-quality paper cups are made of recycled polyethylene, which will produce many harmful compounds in the process of reprocessing. The state explicitly prohibits the use of regenerated polyethylene in food packaging, but because of its low price, some small factories to save costs, still use illegal. At present, the national standard for the quality of paper cups only needs to test for microorganisms, but there is no test for chemicals, because the test is very complicated and difficult to do. Some paper cups due to poor pulp quality, white products for the figure on the large addition of fluorescent bleach, which has cancer risk. She suggested that disposable paper cups can not be used more, such as the best with cold water, to reduce the volatilization of harmful chemicals.
