1.Look: When choosing disposable paper cups, don’t just look at whether the paper cup is white or not. Don’t think that the whiter the color, the more hygienic it is. In order to make the cups look whiter, some paper cup manufacturers add a large amount of fluorescent whitening agents. Once these harmful substances enter the human body, they will become potential carcinogens. Experts suggest that when choosing a paper cup, it is best to take a photo of it under a lamp. If the paper cup appears blue under a fluorescent lamp, it means that the fluorescent agent exceeds the standard, and consumers should use it with caution.

2.Knead: The cup body is soft and not firm, so be careful of water leakage. In addition, choose paper cups with thick and stiff walls. Paper cups with low body hardness will be very soft when pinched. After pouring water or beverages, they will be severely deformed when picked up, or even unable to be lifted, which affects use. Experts point out that generally high-quality paper cups can hold water for 72 hours without leaking, while poor-quality paper cups will leak in half an hour.

3.Smell: The color of the cup wall is fancy, be careful of ink poisoning. Quality control experts pointed out that paper cups are mostly stacked together. If they get damp or contaminated, mold will inevitably form, so damp 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 cup will inevitably affect the inner layer of the paper cup wrapped around it. The ink contains benzene and toluene, which is harmful to health. Buy paper cups with no ink or less printing on the outside.

4.Use: Distinguish between cold cups and hot cups. They “each have their own duties.” Experts finally pointed out that commonly used disposable paper cups can generally be divided into two types: cold drink cups and hot drink cups. Each has its own role. Once “misplaced”, it may have an impact on consumers’ health.
