According to the standard, it is not allowed to print patterns or use recycled materials to make paper cups within the range of 15mm from the edge of the cup to the body and 10 mm from the bottom of the cup to the body. Yesterday, reporters randomly selected three kinds of disposable paper cups of different brands and sent them to the Provincial Quality Inspection Institute for identification. Experts from the provincial quality inspection institute bought paper cups for the public on the spot.
Do not print near the mouth and bottom of the cup
The new paper cup national standard officially implemented on June 1 is the recommended national standard. The Provincial Quality Supervision Bureau said that the new national standards are more standardized than the current industry standards or enterprise standards, and there are no other national standards for paper cups at present. After the implementation of this standard, the paper cup quality inspection is basically carried out in accordance with the new national standard.
The new national standard clearly requires that the printing pattern of paper cup should be clear on the outline, uniform color and no obvious color spots, and "the cup should not be printed on the cup body of 15 mm cup mouth and 10 mm cup bottom, cup body".
Guo Yongmei, an engineer at the plastic and chemical products inspection institute of the Provincial Quality Inspection Bureau, said that when people drink coffee and their lips touch the edge of the cup, the ink in the printed pattern may be swallowed. At present, the ink used in China is basically benzene containing ink, which is harmful to human health. At the same time, if there is a printed pattern on the bottom of the paper cup, it is easy to rub the color against another cup on the wall.
In addition, the standard states that recycled materials shall not be used to make paper cups. The standard also specifies the hardness and permeability of paper cups. The bottom and side of the paper cup shall be free from water leakage or seepage.
The paper cups on sale have patterns on them
Recently, when visiting supermarkets, small shops and food outlets, reporters found that most of the printed patterns of paper cups cover the whole cup body, some of which are too soft, poor in quality and uneven in price. If judged according to the requirements of the new national standard, most paper cups are not up to the standard.
Reporters in New Huadu, Yonghui and other supermarkets found that when selling paper cups, the packaging was marked with manufacturer information, QS certification, implementation standards, materials, production date, shelf life, storage conditions and other relevant information. Reporter bought a disposable paper cup in a convenience store on Yangqiao Road, 3 yuan for a bag, 50 yuan for a bag. The paper cup is very soft and deformed. Only the manufacturer's information, contact information, production date and shelf life are on the outer package.
Raw material or waste paper of paper cup with yellow color
Among the paper cups selected and purchased by reporters, one of them has a yellow surface. Guo Yongmei, an engineer at the provincial quality inspection institute, said that the yellow water cup may be caused by the selection of raw materials. On the one hand, it can process and recycle waste paper. On the other hand, sugarcane pulp can be used instead of wood pulp. The surface of the paper cup made of these two materials will be yellow.
Another optional cup, a pinch deformation, Guo Yongmei introduced that the hardness of this paper cup is not enough, which is not caused by the selection of materials, and may be generated by using waste materials.
