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.

In fact, the choice of paper cups and buy food is the same, need to see the paper cup packaging there is no clear QS logo, manufacturer information, production date.

In fact, the proper choice of paper cups is the same as buying food, need to see the paper cup packaging there is no clear QS logo, manufacturer information, production date. Do not covet cheap and buy unlicensed paper cups. Also want to see clearly the scope of application on the package, a regular disposable paper cup is to indicate the applicable temperature of the paper cup, if you buy a cold drink cup should never be used to fill hot water, so as not to leak and burn. Some large fast food restaurant paper cups are safe to use when dining out. The environment is poor, no health permit restaurants, the use of paper cups are difficult to protect. Moreover, in such a place to eat, food safety is not guaranteed, even if the”5-minute disinfection method” is really effective is useless, or do not eat in such a place as well.
