1. Look: When choosing a disposable paper cup, don't just look at the color of the paper cup. Don't think that the whiter the color, the more hygienic it is. In order to make the cup look whiter, some paper 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 paper cup, citizens should take a photo under a lamp. If the paper cup is blue under a fluorescent lamp, it proves that the fluorescent agent exceeds the standard, and consumers should use it with caution.
2. Pinch: The cup body is soft and not firm, be careful of water leakage. In addition, use paper cups with thick and stiff walls. Paper 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.
Experts pointed out that generally high-quality paper cups can be filled with water for 72 hours without leakage, while the poor quality will see water within half an hour.
3. Smell: the color of the cup wall is fancy, be careful of ink poisoning. Quality supervision experts pointed out that paper cups are mostly stacked together. If they are damp or contaminated, mold will inevitably form. Therefore, paper cups that are damp must not be used.
In addition, some paper cups will be printed with colorful patterns and words. When the paper cups are stacked together, the ink on the outside of the paper cup will inevitably affect the inner layer of the paper cup wrapped around it. The ink contains benzene and toluene, which are harmful to health. Buy paper cups with no ink or less printing on the outer layer.
4. Use: distinguish cold cups and hot cups, each has its own role. Experts finally pointed out that the disposable paper cups we usually use can generally be divided into cold drink cups and hot drink cups, each of which has its own role. Once "displaced", it may have an impact on the health of consumers.
