How much benzene in the hottest food packaging thr

How much benzene in food packaging threatens health

yesterday, Captain Liu of the Inspection Brigade of Lanzhou Bureau of quality and technical supervision revealed to this newspaper that in a recent industry inspection, in the sampling items of benzene content, 3 of the 5 samples did not meet the national regulations, of which the benzene content of Senda packaging exceeded the standard by more than 10 times. From April to June this year, the quality and technical supervision bureaus of Gansu Province and Qinghai Province successfully jointly recovered this batch of inferior milk powder packaging bags with benzene content exceeding 10 times the standard, and none of the 60200 inferior milk powder packaging entered the market

food packaging pollution can not be ignored

in fact, it is not only the packaging enterprises in Lanzhou that have quality problems. A senior person in the industry disclosed to this newspaper yesterday that it is inevitable to modify the benzene content in food packaging after more than 90% of the positive parameters in China are confirmed in the experimental scheme, because it will appear in ink diluents and adhesives. If the manufacturer does not leave enough time for benzene to volatilize in the packaging production process, benzene will continue to remain in the finished products, and if it exceeds a certain amount, it will pose a threat to human health

it is understood that the detection cost of benzene is quite high, and a package will cost more than 1000 yuan. However, most of the packaging production enterprises in China are small enterprises. Due to the restriction of funds and the expulsion of profits, a considerable number of enterprises will not detect the residue of benzene content and will not have the ability to detect benzene content

an insider revealed to this newspaper that since this kind of flexible packaging is mostly composite materials, glue must be used in the composite materials. There are many impurities in Fenxiang and aliphatic glue. In the process of food manufacturing, high-temperature cooking environment is often encountered. In these cases, these harmful substances will free out, form the harmful substance GDI (isocyanate) and penetrate into the food

trace control is difficult to achieve

Wen Xiusong, Secretary General of the professional committee of composite film products of China Plastics Processing Industry Association, said that China allows the use of food packaging materials containing harmful substances such as benzene in trace amounts, but this trace control is difficult to achieve

at present, the vast majority of food enterprises do not allow packaging enterprises to put their own logo on their own packaging. This makes consumers unable to identify good and bad packaging

food enterprises decide whether to buy a certain package based on the low cost and price, and whether to use harmful materials such as benzene, with a price difference of more than 50%. Driven by interests, many manufacturers have chosen this kind of cheap but harmful packaging materials

in addition, according to director Han of the national (Tianjin) packaging quality inspection center, at present, China's law enforcement departments actually do not pay enough attention to food packaging safety. At least within the scope of his knowledge, he has not seen the national quality supervision department actively and systematically carry out hydraulic experiments in this industry, including industrial and mining enterprises, building materials, quality inspection centers, water conservancy and hydropower, bridge engineering, scientific research institutes The ideal experimental equipment for mechanical laboratories in Colleges and universities is to attack and inspect

the way out is to keep up with international standards

Europe and the United States and other countries have not allowed the use of raw materials containing benzene and heavy metals in food packaging. The Japanese government also stipulated three years ago that benzene should not be contained in food packaging materials. It is not only necessary to fundamentally transform the plastic granulator process. Wen Xiusong, Secretary General of the professional committee of composite film products of China Plastics Processing Industry Association, said in an interview with this newspaper yesterday: the relevant standards of our country should be revised, which may be in recent years. It was also learned that China's packaging industry has drafted the "food packaging quality standard", which can be issued as soon as this year

the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China (AQSIQ) has issued a notice on this matter to the local quality and technical supervision departments, requiring that non-ferrous metals such as aluminum alloy and special metal materials and printing materials are sometimes used to reduce the amount of food packaging materials, so as to prevent packaging containing harmful substances from polluting food.
