After several months of "Silence" in Japan and South Korea, the concern that advanced steel material film used in transportation, marine engineering, energy and petrochemical, and key basic parts and components in Zhejiang Province may cause cancer is again rampant. Yesterday, some media reported that due to restrictions in China, Japan and South Korea cancer causing polyvinyl chloride (PVC) food preservative film has been transferred to China. At present, this kind of fresh-keeping film is widely used in supermarkets for packaging, which is just opposite to the short-term development of vehicles. When it is not conducive to the analysis and control of the trend of long-term groove conditions, high temperature or wrapping oily food (such as cooked food) may cause certain harm to human body. Does PVC fresh-keeping film contain carcinogenic potential? According to Dong Jinshi, deputy director of China Packaging Resources Comprehensive Utilization Committee, at present, there are three main raw materials for domestic production of food preservative film, namely polyethylene (PE), polyvinyl chloride (PVC) and polyvinyl chloride (PVDC). Most of the fresh-keeping films sold on the market use PE as the raw material, which is recognized as the safest because it does not add any plasticizer in the production process. It is understood that PVC is a hard plastic. To pull it into a transparent and soft fresh-keeping film, a large amount of plasticizer must be added. The main component of plasticizer is ethylhexylamine (de-ha). As ethylhexylamine (DEHA) is easy to be separated out in PVC fresh-keeping film, it will cause carcinogenesis to human body after food is brought into human body, especially causing endocrine and hormonal disorders, so it will cause great harm to human body. Dong Jinshi said that most domestic supermarkets are willing to use PVC fresh-keeping film for packaging because PVC fresh-keeping film has good transparency, viscosity and is not easy to crack, and machine packaging can also be used. "Although there is no harm in wrapping raw and cold food with PVC cling film, DEHA is not suitable for packaging cooked food or food heating because it can be dissolved in oil or precipitated at high temperature." PVC fresh-keeping film is not unusable. After yesterday's investigation, it was found that many supermarkets in Beijing used sticky PVC fresh-keeping film when packaging fresh vegetables, fruits, cooked food and other products. An unnamed person in charge of a large supermarket in Beijing said that the food preservative film used in the supermarket came from two Japanese suppliers. The person in charge of the supermarket admitted that at present, the country has not restricted the use of PVC fresh-keeping film. Even if it is prohibited abroad, it is only "legal and unreasonable" at most in China. "Moreover, the national authority has not clearly announced the harmfulness of PVC fresh-keeping film, so consumers need not worry too much." The staff of Beijing plastic products quality supervision and inspection station said that as the national inspection standards for such products have health requirements, as long as they meet the standards, they should be said to be safe. However, according to Dong Jinshi, the use of PVC as a food packaging material was banned in Europe as early as a few years ago. The United States, Japan, Singapore and South Korea have now completely banned the use of PVC packaging materials.
