Common sense of paper cup identification when customers order
When purchasing disposable cups, we should pay attention to the following points:
First, the product packaging should be noted with the name of the manufacturer, QS production license and number, address of the manufacturer, product implementation standards, production date, validity and other information. If the packing is too poor and the printing is too rough, you'd better not buy it.
Second, you should choose products with full shape, no wrinkling, certain thickness and no deformation. If the cup body is too soft or the cup is easy to crack after tearing, most of them are unqualified products.
Third, smell whether there is a peculiar smell, if you open the cup packaging, it is mostly due to the use of inferior toxic ink.
Fourth, don't be greedy for the paper cup with too white color. The paper cup with too white color is likely to be added with fluorescent substances. It is not easy to be decomposed and eliminated. Accumulation in the body will affect the normal development and growth of cells. In serious cases, it will cause cell mutation, weaken immunity and endanger human health. Therefore, experts suggest: paper cup, or a little lighter color is better.
Fifth, consumers should pay attention to whether the paper cup is a cold water cup or a hot water cup. There is a layer of food wax on the surface of the cold water cup, which is safe at 0 ~ 5 ℃. However, as long as the temperature of the water exceeds 62 ℃, the wax will melt, which may lead to diarrhea and other diseases after being eaten by human body.
