In order to achieve the water barrier effect during the production of paper cups, a polyethylene water barrier film is coated on the inner wall. Polyethylene is the safest chemical 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 to the paper cup. Carbonyl compounds are not volatile at room temperature, but when hot water is poured into a paper cup, they may volatilize, so people will smell strange smells. From a general theoretical analysis, long-term intake of this organic compound must be harmful to the human body.

The earth-friendly disposable cups of Soton use corn starch as the raw material. The product has a light popcorn fragrance, good sealing performance, and no leakage. It is non-toxic, pollution-free, and odorless, and will not damage the soil structure after degradation. It is truly "from nature and returning to nature".
