Observe: When choosing a single wall cup, don't just look at the color of the single wall cup. Don't think that the whiter the color, the more hygienic it is. In order to make the single wall cup look whiter, some single wall cup manufacturers add a lot of fluorescent whitening agent. Once these harmful substances enter the human body, they will become potential carcinogens. Experts suggest that when choosing a single wall cup, you should take it under light. If the single wall cup is blue under a fluorescent lamp, it proves that the fluorescent agent exceeds the standard.
Pinch: If the single wall cup is soft and not firm, be careful of water leakage. In addition, use single wall cups with thick and stiff walls. Single wall cups with low body hardness are very soft when pinched. After pouring water or beverages, they will be severely deformed when held up, or even unable to be held up, which affects the use. Generally, high-quality single wall cups can be filled with water for 72 hours without leakage, while the poor quality will leakage in half an hour.
Smell: If the color of the outside of single wall cup is fancy, be careful of ink poisoning. If single wall cups are damp or contaminated, mold will inevitably form. Therefore, single wall cups that are damp must not be used. In addition, some single wall cups will be printed with colorful patterns and words. When the single wall cups are stacked together, the ink on the outside of the single wall cup will inevitably affect the inner layer of the single wall cup wrapped around it. The ink contains benzene and toluene, which are harmful to health.
Use: Distinguish cold cups and hot cups, each has its own role. Disposable paper cups we usually use can generally be divided into two types: cold drink cups and hot drink cups, each of which has its own role. Once being displaced, it may affect the health of consumers. Cold drink cups are usually single wall cups with wax inside, while hot drink cups are usually double wall cups with PE film.
The quality of single wall cups on the market is uneven with the greater hidden dangers. In order to make the single wall cup look whiter, some single wall cup manufacturers have added fluorescent whitening agents. This fluorescent substance can cause cell mutations. Once it enters the human body, it will become a potential carcinogen.
In order to achieve the water barrier effect of the single wall cup, a polyethylene water barrier film is applied to the inner wall during production. 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, polyethylene may be oxidized into carbonyl compounds when it is hot melted or applied to single wall cup. Carbonyl compounds are not volatile at room temperature, but when hot water is poured into the single wall cup, they may volatilize, which will cause strange smell. Although there is no research to confirm what kind of harm the carbonyl compounds released from the single wall cup will bring to the human body, long-term intake of this organic compound must be harmful to the human body.
What is more worrying is that some inferior single wall cup use 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. The state has banned the use of recycled polyethylene for food packaging, but because recycled polyethylene is cheap, some small factories still use it in violation of regulations to save costs.
