How to choose a paper cup?

Paper Cup For Hot Drink Double Wall.jpgA paper cup is a paper container which is obtained by mechanically processing and bonding a base paper made of chemical wood pulp, and has a cup shape. Paper cups for frozen foods can be coated with ice cream, jam and butter. Paper cups for hot drinks are coated with plastic, resistant to temperatures above 90 °C, and even bloom in water. The paper cup is characterized by safety, hygiene, lightness and convenience. It can be used in public places, restaurants, restaurants, and is a one-off item.

When selecting 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 in order to make the cup look whiter. Once these harmful substances enter the human body, they become potential carcinogenic factors. Experts suggest that the public should take the photo under the lamp when selecting the paper cup. If the paper cup is blue under the fluorescent light, it proves that the fluorescent agent exceeds the standard and consumers should use it with caution. The cup is soft and not strong, and it is leaking carefully. In addition, it is necessary to use a paper cup with a thick cup wall. The cup with a low cup hardness is very soft. After pouring into water or a drink, it will be severely deformed when it is put up, and it will not end up, which will affect the use. Experts pointed out that generally high-quality paper cups can hold water for 72 hours without leakage, and poor quality will leak water for half an hour.

The color of the cup wall is fancy, beware of ink poisoning. Quality supervisors pointed out that paper cups are stacked one on top of the other. If they are wet or contaminated, molds must form, so the paper cups that are damp should not be used. In addition, some paper cups will print 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 outside, and the ink contains benzene and toluene, which is harmful to health. Purchase paper cups with no ink printing or less printing on the outer layer. Experts finally pointed out that the disposable paper cups we usually use can be divided into two types: cold drink cups and hot drink cups. They all have their own functions. Once they are misplaced, they may have an impact on consumers' health.
