How long is the shelf life of disposable paper cup?

At present, the quality of disposable paper cups on the market is uneven, with great hidden dangers, and most families keep them improperly, so that makes the cups damp and moldy, causing the breeding of bacteria and fungi. If we use these cups, it will be harmful to our body and easily cause respiratory diseases. When buying disposable paper cups, the most important thing is to look at the production date and shelf life.


Generally, the shelf life of disposable paper cups is 2-3 years, but some disposable paper cups are labeled, so we need to identify carefully.


In order to make the cups look whiter, some paper cup manufacturers add a large of fluorescent whitening agents, which can mutate cells and become potential carcinogens if they enter the human body. In order to make the paper cups be water-proof, a layer of polyethylene water-proof film will be coated on the inner wall. Polyethylene is the safest chemical substance in food processing. However, if the raw materials are not good or the processing technology is not qualified, the polyethylene may be oxidized to carbonyl compounds during hot melting or coating on the paper cup. Carbonyl compounds are not easy to volatilize at normal temperature, but they may volatilize when pouring hot water into a paper cup, so people will smell odor. Long term ingestion is harmful to our body.
