A paper cup that is easy to carry and use, and is inexpensive. It is a common tool for drinking water or beverages in many homes and public places. But in the process of using, we will find that some hot drinks have a higher temperature, or cold drinks have a lower temperature, which will not be comfortable for us to hold, so at this time we need the help of a Paper cup sleeve .

The inferior paper cup sleeve uses recycled polyethylene, which will undergo cracking changes during the reprocessing process, and produce many harmful compounds, which are more likely to migrate into the water during use. Polyethylene is the safest chemical substance in food processing. However, if the selected material is not good or the processing technology is not good enough, the polyethylene may be oxidized to carbonyl compounds during the process of hot melting or applying it to the paper cup. Carbonyl compounds are not easy to volatilize at room temperature, but when hot water is poured into a paper cup, they may volatilize, so people will smell a strange smell. From a general theoretical analysis, long-term intake of this organic compound must be harmful to the human body. Therefore, the material selection of the paper cup sleeve and paper cup is still very important.

And the Ps lid is the same, it is something we often use, so the material is very important.
