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 will be. Some paper cup manufacturers have added a lot of fluorescent whitening agents in order to make the cup look whiter. Once these harmful substances enter the human body, they will become potential carcinogenic factors. Experts suggest that citizens should take a photo under the lamp when choosing paper cups. If the paper cups are blue under fluorescent lamps, it proves that the fluorescent agent exceeds the standard, and consumers should use it with caution.
2. Pinch If the cup is soft but not firm, be careful of water leakage. In addition, paper cups with thick and stiff walls should be selected. Paper cups with poor stiffness are very soft to pinch. After being poured into water or drinks, they will be severely deformed or even unable to be lifted, which will affect the use. Experts pointed out that generally, high-quality paper cups can hold water for 72 hours without leakage, while poor-quality paper cups will seep in half an hour.
3. Smell The wall color of the cup is fancy, so beware of ink poisoning. Quality supervision experts pointed out that most paper cups are stacked together. If they are wet or contaminated, mold will inevitably form, so the wet paper cups 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 cups will inevitably affect the inner layer of the paper cups wrapped around it. However, the ink contains benzene and toluene, which is harmful to health. It is best to buy paper cups with no ink or less printing on the outer layer.
4. Use Distinguish between cold cups and hot cups. They "have their own functions." Experts finally pointed out that the disposable paper cups we usually use can generally be divided into cold drinks cups and hot drinks cups. They each have their own functions. Once they are "misplaced," they may threaten consumers' health.
