Because of its convenience practicality, disposable paper cups have become the common drinking utensils used by many families units to entertain guests. Many consumers go to supermarkets street shops to buy at will, they don't care about the phenomenon of water leakage peculiar smell. They don't realize that they are buying unqualified paper cups. Paper cups are disinfection products, which need to be strictly approved before they can be produced sold. However, the quality of disposable paper cups on the market is uneven. How to buy qualified paper cups to make our drinking safer? The staff of Yantai health supervision institute offered advice to the public to identify the quality of products the senses.

1、 Look at the health license number marked on the label: according to the relevant regulations of the state, disposable paper cups can be used for production only after obtaining the health license issued by the provincial municipal health administrative department, so the format of the health license number marked on the label should be (abbreviation of province, autonomous region, municipality directly under the central government) wxzz (year of issue) No. XXXX.

2、 Look at the marked production date: disposable paper cup belongs to disinfection product has a shelf life (more than two years). But in fact, many products on sale are marked with the production date, some of them are also difficult to see. Consumers must check whether the product is clearly marked with the production date when purchasing.

3、 Check whether the packaging is tight: during the inspection, it is found that the packaging seal of many paper cups is just a simple adhesive tape, which can be easily opened by consumers, so it is difficult to ensure the sanitary condition of the paper cups.

4、 Look at the appearance: don't think that the whiter the color, the more sanitary it is. Some paper cup manufacturers add fluorescent whitening agent to the base paper in order to make the cup look whiter. Once these substances enter the human body, they are harmful to the health of the body.

When choosing a paper cup, you can use your hands to squeeze gently on both sides of the cup to roughly know the stiffness of the cup body.

6、 According to the use judgment: the disposable paper cup for daily use can be divided into cold cup hot cup, can be divided into wax coating, film coating film coating according to different coating materials. Generally, there is a layer of food wax on the surface of cold cup. When the temperature is 0 ℃ - 5 ℃, the wax is very stable safe, but as long as the water temperature is over 62 ℃, the wax will melt, which is suitable for boiling water to make tea; the surface of hot cup is pasted with a special film, which is only heat-resistant, but also non-toxic harmless under the immersion of high temperature drinks. The staff of the health supervision institute suggested that the public should pay attention to distinguish when purchasing, so as to make appropriate choices according to the purpose.
