What are the hazards of the paper cups that are not up to standard?


First of all, the cups that are not up to standard are not stiff enough. After adding hot water, it is easy to cause burns. Secondly, the non-standard paper cups have fluorescent substances that endanger human health, and the fluorescent substances are not easily decomposed and eliminated. Affect the normal growth and development of cells, excessive exposure, toxicity accumulation will form a potential cancer risk; In addition, the paper cup body ink that does not meet the standard is easy to decolorize, and will enter the human body when drinking water.




How to tell if the paper cup is qualified?


If the commercially available paper cup has a noticeable irritating taste after opening the outer packaging bag, or the paper cup has a strange smell during use, it may be that the manufacturer uses recycled plastic or inferior paraffin wax when producing the paper cup, and it is not recommended to purchase it.




How to choose to use paper cups?


First, look for the QS mark. According to the requirements of the AQSIQ, products such as food paper packaging containers must have the QS (Food Quality and Safety Market Access Mark) mark to be sold.


Second, the product identification needs to be complete. The complete product identification of the paper cup product includes the name, trademark, implementation standard number, production date and shelf life or production batch number and limited date, product type, specification, grade and quantity, product conformity mark, name of the manufacturer (or agent) and address.


Third, rather health is not gorgeous. If the color of the paper cup is poor or the printing technology is not enough, it will cause the ink to come into contact with the paper cup through the mouth and cause damage to the body, or stick to the hand when the hand touches, which may cause health hazards. Therefore, it is recommended that consumers choose not to choose too many patterns and too bright and rich paper cups when purchasing paper cups. If you open the package and smell a pungent smell, it is also recommended not to buy.


Fourth, the cup is firm and guaranteed. Due to the different paper materials used, the cup body hardness of the commercially available paper cup products is not the same. It is recommended that consumers can lightly pinch when purchasing, and try to buy a cup of hard paper cup.




Tips


Try not to use a disposable paper cup to fill the water. To prevent water penetration, the inner wall of the paper cup is coated with a thin layer of wax. When the water temperature exceeds 40 ° C, this layer of wax will melt. Therefore, do not pack more than 40 ° C water in the paper cup. Paper cups produced by regular manufacturers use food-grade wax to make the inner wall coating of the paper cup. Therefore, even if the water temperature is too high, the wax on the inner wall of the paper cup is dissolved, and there is no safety problem. However, there are also unscrupulous processing plants that use low-cost industrial paraffin to coat the inner wall of paper cups. Industrial paraffins contain substances such as benzene and polycyclic aromatic hydrocarbons that are harmful to humans, which can damage the nervous system and hematopoietic system of the human body. Therefore, when purchasing, you must choose paper cups produced by regular manufacturers.
