At the beginning of the school year, students receive many new textbooks, and in order to make the appearance of their new books better and to make them more resilient, parents choose to provide their children with books in their school bags. On the other hand, a number of parents indicated that they would choose paper materials. As to the reasons for the preference for paper-based paper, parents expressed concern that plastic wrappings were toxic and could affect the health of children. In recent days, the jiangsu provincial quality inspectorate has issued a quality monitoring and risk analysis report on the products, and four of the 36 batches monitored found problems. According to the expert, four batches of sheeted film found problematic, with the main problem being benzene solvent residues and the detection of benzo- and diphenyl. This is mainly due to the absence of fully removed volatile compounds during the process, which can be used in a manner harmful to humans through the odour of stinging。
So, in chengdu, what happened to the sale of book skin? At 10 a. M., journalists first visited the stationary shop around the west temple primary school in the city's capital city, where they searched the bookskin, and when they arrived in front of the shop, the boss enthusiastically marketed it to us. According to the owner of the stationary shop, there is no need to process any of the books currently being sold on the market, so that books can be embedded and easily used. The breakdown by material is broadly divided into plastics, paper and plastic membranes at a price of one dollar. When journalists expressed concern about the quality of these bags, the bosses indicated that their products were marked with the manufacturer's and the production number, and were marked as pp materials, which were tested as eligible products by the national centre for monitoring the quality of educational materials. And what about the stationary store near the other school? At 1 p. M., the journalist returned to a stationery store near the chengdu nan gate. In this stationary shop, we found a piece of “three-nil” paper that did not contain any factory site, and the owner of the store said that he had arrived at a wholesale market in chengdu and had not noticed those aspects. Subsequently, he also indicated that he would immediately return the merchandise to the shelf. So, what should we pay attention to when choosing the book? First: when buying a bag of paper, the packaging can be removed to smell if there is an irritating smell, and if there is a heavier irritant smell, the purchase should be avoided. Second: good quality book skins are flat, clean, luminous and resilient, while low quality book skins are light blue or yellow, easily torn and light is poor. In addition, parents should remind the child not to suck on the finger of the skin and develop hygiene habits for washing hands after reading。
