Whether at home or in restaurants, disposable cups is used more and more. People think it is both healthy and convenient. However, the sampling results of paper cup products recently announced by the General Administration of Quality Supervision, Inspection and Quarantine show that the sampling pass rate of paper cup products is 86.9%. Although the qualified rate is high, a few paper cups contain a lot of harmful substances-fluorescent agents, which can mutate cells and become potential carcinogenic factors. Therefore, be extra careful when choosing paper cups.
According to the quality inspectors of AQSIQ, one of the problems of disposable paper cups is unqualified hygiene and safety. A few paper cup manufacturers will add a lot of fluorescent brighteners to make the cups whiter. According to national standards, the maximum fluorescent area on a paper cup cannot exceed 5 square centimeters.
The hardness of the cup is not up to standard, so it is very soft to knead by hand. After pouring water or drinks, it will be seriously deformed and even unable to lift, which will affect the use. The main reasons for the disqualification are the poor quality of raw materials and the low and thin base paper used.
Water leakage or seepage phenomenon, after pouring water, water will leak or ooze from the gap or bottom of the cup, so this product can not be used. The unqualified reason is that the seams of paper cups are not completely bonded during processing, resulting in water leakage or seepage.
The correct choice of disposable cups should be based on the standards and health knowledge of the national quality supervision department. First, look at the packaging. The product packaging shall indicate the name and address of the manufacturer, product implementation standards, production date and expiration date. In addition, the packaging bag should be completely sealed and not damaged, otherwise it will be easily polluted by the environment during transportation and sales, and the hygiene cannot be guaranteed.
