1. Look: When choosing disposable paper cups, don’t just look at the color of the paper cups. Don’t think that the whiter the color, the more hygienic. Some paper cup manufacturers add a lot of fluorescent whitening agents to make the cups look whiter. 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 the lamp. If the paper cup appears blue under fluorescent light, it proves that the fluorescent agent exceeds the standard, and consumers should use it with caution.
2. Pinch: The body of the cup is soft and not firm, be careful of water leakage. In addition, choose 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 picked up, or even unable to be picked up, 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 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 polluted, mold will inevitably form, so damp paper cups must not be used. In addition, some paper cups from paper cup manufacturers will print 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 outside. The ink contains benzene and toluene, which is harmful to health. , it is best to buy paper cups with no ink printing or less printing on the outer layer.
