When some consumers buy Single Wall Coffee Cups, they generally think that the whiter the paper cup, the cleaner it is. This actually has a misunderstanding.
Some cups look white because of the use of fluorescent brighteners, which are harmful to the human body.
In addition, disposable paper cups are generally divided into cold drink cups and hot drink cups, which will be marked on the standard paper cups. Do not hold hot drinks in the cold drink cup, because the surface of the cold drink cup generally has a layer of food PE film. If the water temperature is too high, the PE film will melt into the body. Long-term large quantities of consumption will endanger human health.
Disposable paper cups are often stacked together and sealed in plastic packaging for sale. Although they are visible and tangible, consumers do not know the quality of the paper cups. Generally, price is the key factor. This buying behavior To a large extent, it provides a market for products of inferior quality. So when choosing disposable paper cups, we need to pay attention to the following aspects.
1. Look at the packaging and labels. Generally, paper cups should be sealed in plastic packaging, and the packaging bag should not be damaged. The product packaging should indicate the name, address, and telephone number of the manufacturer. Also pay attention to whether the product's implementation standard, production date, expiration date, etc. are indicated on the packaging.
2, check whether the appearance is deformed. Paper cups with poor cup body stiffness are very soft when pinched by hand. After pouring water or beverages, they will be severely deformed when held up, or even cannot be held up, which seriously affects the use. At the time of purchase, you can use your hands to gently squeeze both sides of the cup to judge the cup's body stiffness.
3. Test the fluorescent agent through light. The paper cup can be placed under an ultraviolet lamp or a currency detector. If the surface of the paper cup is obviously brighter and appears blue-violet, it can be determined that the paper cup contains a fluorescent whitening agent.
4. Paper cups cannot contain alcoholic beverages. Because alcohol contained in alcoholic beverages will dissolve the coating on the surface of the paper cup.
