The reporter visited several supermarkets near Dieshan Road in Nanchang City and found that there are still a large number of paper packaging and paper containers sold without QS certification on the market. Nearly two-thirds of the packs of 50-packed paper cups have no QS certification at Volkswagen. The salesperson told the reporter that she is also not sure whether QS certification is required on the packaging. In Xiangshan North Road MasterCard Supermarket, nearly half of the paper cups have no QS certification. Some consumers also said in an interview with reporters that it is not known that QS certification is required for the outer packaging of paper cups, and buying paper cups is generally considered only in terms of price and appearance.
During the interview, the reporter found that most brands of ice cream and instant noodles are printed with QS certification on the paper packaging.
According to the person in charge of the Food Department of the Quality Supervision Bureau of Nanchang City, the inner layer of the qualified paper cup is made of polyethylene resin, and the unqualified paper cups are mostly replaced with waste plastics. The paper used in the paper cup itself also uses a lot of recycling. Waste paper, the cost of such inferior paper cups is less than one-eighth of the quality products.
It is reported that disposable cups currently sold on the market are mainly divided into three types: one is made of white cardboard, which is mainly used to hold things dry and cannot hold water and oil; the other is a waxed paper cup. Soaked with wax, so as long as the temperature of the water in the cup exceeds 40 degrees Celsius, the wax melts, and the wax contains carcinogenic polycyclic aromatic hydrocarbons; the third is a paper plastic cup that is commonly used nowadays, with a layer of paper outside. The inside is a layer of coated paper. If the material selected during the production is not good or the processing technology is not closed, harmful substances will be produced during the production process. In addition, some manufacturers add a large amount of fluorescent whitening agents to make the cup look whiter, and use it for a long time, which is harmful to the human body.
Experts said that poor quality paper cups are well-differentiated. The main methods are: one look, two pinch, and three smells. Inferior paper cups generally have impurities on the surface, the cups are soft, and they tear when lightly, and they give off a pungent smell of ink, indicating that the paper cup contains benzene. Select QS certified paper cup quality is more assured.
"A paper container is not conspicuous, but it is a type of consumer product that is most commonly touched by the public. It is important to pay attention to the purchase in the future," said the person in charge of the Food Department at the Nanchang Quality Supervision Bureau.
