Nowadays, disposable tableware represented by paper cups has entered people's lives, and its safety issues have also attracted much attention. The state stipulates that disposable paper cups cannot use recycled waste paper as raw materials, and cannot add fluorescent bleach. However, many paper cups use recycled paper as raw material, and add a large amount of fluorescent bleach to make the color white, and then add some industrial calcium carbonate and talc to increase its weight.In addition, in order to withstand high temperature, the paper cup is covered with a layer of coated paper. According to the regulations, standard non-toxic polyethylene should be selected, but some manufacturers use industrial polyethylene or waste plastics for chemical packaging instead.
We can distinguish the pros and cons of paper cups through the following four steps, so as to select high-quality paper cups.
The first step is "see". When choosing a disposable paper cup, don't just look at the color of the paper cup.Some paper cup manufacturers have added a large amount of fluorescent whitening agents in order to make the cups look whiter. Once these harmful substances enter the human body, they will become potential carcinogens. Experts suggest that when people choose paper cups, it is best to look under the lights. If the paper cups appear blue under fluorescent lights, it proves that the fluorescent agent exceeds the standard, and consumers should use it with caution.
The second step is "pinch". If the cup body is soft and not firm, be careful that it will leak. It is necessary to choose paper cups with thick walls and high hardness. After pouring water or beverages into paper cups with low hardness, the cup body will be seriously deformed, which will affect the use. Experts point out that generally high-quality paper cups can hold water for 72 hours without leakage, while poor quality paper cups will seep water for half an hour.
The third step is "smell". If 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 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 on the outside. The ink contains benzene and toluene, which are harmful to health, so It is best to buy paper cups with no ink printed on the outer layer or with less printing.
The fourth step is "use". A big function of paper cups is to hold beverages, such as carbonated drinks, coffee, milk, cold drinks, etc. Beverage paper cups can be divided into cold cups and hot cups. Cold cups are used to hold cold beverages, such as carbonated beverages, iced coffee, etc. Hot cups are used to hold hot beverages such as coffee, black tea, etc. Experts point out that the disposable paper cups we usually use can generally be divided into two types, cold drink cups and hot drink cups.
