When consumers choose disposable paper cups, there are no microbiological, physical and chemical testing equipment, but they can use the steps of seeing, smelling, photographing and kneading to judge whether the quality and safety of paper cups are qualified.
To select a qualified paper cup, the first thing is to see whether there is QS production license mark, manufacturer information and production date on the outer package of the paper cup. In addition, the scope of application indicated on the package should be checked. Regular disposable paper cups are marked with the applicable temperature of paper cups.
Then check the appearance of the paper cup. The mouth of the paper cup should not be sunken or wrinkled; the coating layer and waxing layer should be uniform, and the cup body should be clean and free of foreign matters. The more simple the printing appearance pattern and color of paper cup, the better. The printing pattern shall be clear in outline, uniform in color and free from obvious color spots. According to the provisions of the recommended national standard "paper cup" (GBT 27590-2011) which was implemented on June 1, this year, the paper cup should not be printed within 15mm from the cup mouth to the cup body and within 10mm from the cup bottom to the cup body. Although because of the protection of the film, ink components will not necessarily be brought into the food, but choose the cup with no printing at the bottom of the cup will be safer.
