Alert: cheap plastic bags contain toxins
at the science and Technology Salon held by the Shanghai Association for science and technology a few days ago, the "green packaging" technical experts and the relaxation experimental machine horizontal horizontal horizontal pull structure food experts reminded that part of the plastic packaging bags that people use daily and most of the "free packaging bags" provided by small vendors are made of waste recycled materials, and the harm of this "black pollution" is even greater than "white pollution". Therefore, experts suggest that the use of food packaging bags produced from waste recycled materials should be completely prohibited
the production level of processing workshops is low
a survey shows that at present, the Shanghai farmers' market consumes more than 24000 tons of plastic packaging bags a year, with an average consumption of 1.7 kg per person per year. Such a large demand and supply comes from hundreds of waste plastic film processing sites around Shanghai, and the production raw materials of these processing sites are plastic waste. These plastic wastes sorted and recycled from garbage have complex components, and some have even been used to contain pesticides, fertilizers, or as agricultural mulch, which inevitably contain toxic and harmful substances. These small workshops have poor equipment, weak technical force and poor sanitary conditions, and it is impossible to meet the requirements of producing food packaging materials
according to expert analysis, food packaging bags are often in direct contact with food in use. Toxic and harmful substances in waste recycling and industrial pigments, talc powder and other components added in processing are easy to separate out, thus polluting food. Although the harm caused by this kind of packaging bag is not as strong as the work a consumed by reading the impulse sample from the dial reading as the bacterial infection, it is mostly imperceptible chronic poisoning
toxic packaging bags are extremely difficult to identify
China's "measures for the hygienic management of plastic products and raw materials processed by grinding machines on the surface of food materials" clearly stipulates that "recycled plastics shall not be used for processing plastic tableware, containers and food packaging materials." It is learned that in the production of regular food packaging bags, plastic packaging materials for food, such as polyethylene, are used. So, how do ordinary consumers distinguish between formal packaging bags and "toxic packaging bags"
some people have given sensory detection method, shaking detection method, combustion detection method and other detection methods, but relevant experts of Shanghai Packaging Technology Association believe that these methods can not effectively identify "toxic packaging bags"
the recycling of waste plastics does pose a problem for food hygiene supervision. Because the sources of waste plastics are unknown and the ingredients are complex, it is impossible to formulate targeted health standards. Therefore, the health quality of food packaging bags produced from waste plastics can not cope with trade protectionism and can not be effectively supervised
spend a little more money on health
at present, there is no effective means to regulate "toxic plastic bags", how should citizens protect their health
to put an end to "toxic plastic bags", first of all, citizens need to consciously resist "toxic plastic bags". In order to reduce costs, businesses that use "toxic plastic bags" buy cheap "toxic plastic bags" from salesmen at waste plastic film processing sites. In fact, the cost of regular packaging bags is only 1-3 cents less than that of such miscellaneous goods, that is, customers can use hygienic and healthy food packaging bags as long as they spend a few more cents
at the same time, resisting food packaging bags produced by waste recycling does not affect the recycling of waste plastics, which can be used for processing garbage bags, packaging of building materials and industrial utilization
expert suggestions 1. Customers should ask merchants to provide regular food packaging bags, and merchants can also charge appropriate packaging fees
2. Animal food, such as poultry, animal meat, fish and shrimp and other aquatic products, must use formal food packaging bags
3. For vegetables, fruits and other commodities that are not easy to produce cross pollution, citizens are encouraged to bring their own packaging baskets and bags and try to use less recycled plastic bags provided by vendors
