How to choose paper cups? Many customers who buy paper cups don't know this very well. I think that there is not much knowledge in cup, so you can buy it casually. In this way, you are very wrong. In fact, how to choose paper cups is also a learning. Here, Wang will explain to you:
1. When selecting disposable paper cups, do not only look at the white or white paper cup color, do not think that the whiter the color is, the cleaner the more sanitary the color is. Some paper cup manufacturers add a large number of fluorescent brighteners to make the cup look whiter. Once these harmful substances enter the human body, they will become potential carcinogens. Experts suggest that when choosing paper cups, the public should take a light under the lamp most. If the paper cup is blue under the fluorescent lamp, it is proved that the fluorescent agent is over standard and consumers should use it carefully.
2. The cup body is not firm and soft. In addition, the paper cup with thick and hard wall should be selected. The paper cup with poor stiffness of cup body is very soft. After pouring water or drink, it will be severely deformed when it is put up, and even cannot be ended, which will affect the use. Experts point out that the general high-quality paper cup can hold water for 72 hours without leakage, and the poor quality of half an hour will leak.
3 smell the color of the cup wall, and be careful of ink poisoning quality supervision experts pointed out that the paper cups are stacked together. If they are wet or polluted, mould will inevitably form, so the paper cup affected by moisture must not be used. In addition, some cups will be printed with colorful patterns and words. When the cups are stacked together, the ink outside the paper cup will inevitably affect the inner layer of the paper cup wrapped outside the cup. The ink contains benzene and toluene, which is harmful to health. The outer layer of paper cup without printing ink or printing less is the most purchased.
4. The experts who distinguish cold cups and hot cups, they have their own duties, and finally point out that the disposable paper cups we usually use can be divided into two types: cold drink cup and hot drink cup. Each of them has its own duties. Once "misplaced", it may threaten the health of consumers.
