Remember not to use hazardous chemicals in food packaging materials [China Packaging News] no matter what kind of plastic packaging is used, the requirements of green packaging should be met: reduce waste pollution; Solve the environmental protection problems of solvents; Recycling. Environmental friendly and pollution-free green packaging will be paid more and more attention by the society. Therefore, we should vigorously develop green packaging, do a good job in packaging waste treatment and resource recycling, and realize the requirements of sustainable development

food contact materials: beware of potentially dangerous chemicals

remember bisphenol? At present, China's economy is facing downward pressure, increasing a? It has been nearly three years since bisphenol A in baby bottles may induce premature puberty, and the national standard for the safety of baby bottles is still far away. Recently, the enterprise alliance standard of "safety requirements for baby bottles" compiled by the China toy and baby products association was finally released, filling the gap in the national and industrial safety standards for baby bottles in China

recently, American scientist Joe adtongji published a paper in the Journal of epidemiology and public health, saying that chemicals used in food packaging, storage and processing may cause long-term harm to human health

adtongji said that many potentially dangerous chemicals were found in food contact materials, including the inner coating of cans, the coating of folding cartons and the sealing cover of glass bottles. A small amount of chemical components will penetrate into food through these materials. With the rise of temperature, the extension of food storage time and the use of certain types of packaging materials, the diffusion rate of chemicals will be faster

according to adtongji, more than 4000 chemicals have been found on food packaging materials. For example, asbestos can be used in rubber as an indirect food additive in the United States, while the carcinogen formaldehyde is widely used in PET plastic bottles, but the content is low. PET plastic bottles are the most commonly used packaging materials for carbonated beverages. In addition, formaldehyde can also penetrate into food through tableware made of melamine formaldehyde

some experts think it is exaggerated

some experts do not agree with adtongji's point of view. Ian Musgrave, a pharmacologist at the University of Adelaide, believes that adtongji's paper exaggerates the harm of formaldehyde in food packaging. He said: many foods contain natural formaldehyde. Decomposing the formaldehyde in 100g apples requires mineral water in at least 20L polyester bottles. According to this, fresh fruits and vegetables should also be noted for possible cancer. We cannot underestimate the potential pollution of harmful packaging materials on food when leaving the factory, but this possibility is very small. This paper does not pay attention to physiology and other health hazards, but blindly emphasizes the harm of formaldehyde micro penetration, which is easy to cause unnecessary concern

the research on low-dose chemicals is not in-depth.

Ian REI, an honorary professor at the University of Melbourne, said that although the harm of chemicals has long been known, people have not done much in-depth research on the long-term harm of low-dose chemicals. But many manufacturers have felt the pressure from the market and consumers. For example, baby bottles containing bisphenol A can no longer be sold, and the plasticizer phthalate has also disappeared from the packaging of many foods

Both bisphenol A and plasticizer are caused by food packaging. So far, the source and harm of plasticizer are still unclear

the national food safety risk assessment center said that the sources of plasticizer in food are relatively complex, and this substance itself has the characteristics of easy migration. After many rounds of investigation, investigation and in-depth analysis, it mainly comes from two aspects: one is the migration of plastic containers, pipes, packaging materials and sealing materials in contact with food into food. The second is plasticizers in the environment, but not all experimental machines are suitable for the impact of flexible packaging materials on food. For example, plasticizers in soil and water may also enter the food chain to affect food
