PVDC film may be the first choice for food preservation

recently, the safety of PVC food preservation film has been questioned. So, what kind of products are used to replace PVC food preservative film without affecting human health? At the 2005 National Symposium on new products and deep processing technology in the plastic packaging film industry held from November 21 to 23, lichengxin, deputy general manager of the Sino foreign joint venture Xingtai Weite Plastic Industry Co., Ltd., said that the national environmental protection department had asked the company to provide samples of its polyvinylidene chloride (PVDC) food packaging film in order to understand the characteristics of this product, When the extensometer mobile arm is under force, this kind of PVDC food preservation film with high barrier performance may be launched in large supermarkets in Beijing

the special inspection results of PVC food fresh-keeping film recently released by the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China can reduce the cost. It shows that some PVC fresh-keeping films used for food packaging contain DEHA plasticizer. Driven by the market, they will have an impact on human health under specific conditions. The PE and PVDC food preservative films tested at the same time are safe

Xingtai Weite Plastic Co., Ltd., a Sino foreign joint venture, is the only enterprise in China that has PVDC coextrusion equipment, and the film blowing equipment meets the requirements of normal application and can be mass produced. Lichengxin said that the national environmental protection department has just asked them to provide samples of PVDC food preservative film by fax, and said that the cooperation between the two sides will have a broad prospect, because at present, PE food preservative film can not meet the requirements of customers, and the safety of PVC food preservative film with two circulating oil tanks closed has been questioned. Only PVDC film can achieve the use effect of PVC film. At present, Wal Mart, Carrefour and other large supermarkets in Beijing are looking for the national environmental protection department to ask what can be used as a substitute, and the environmental protection department found their company

lichengxin said that the additives of PVDC film and PVC film are very different. The former does not contain heavy metals and meets the requirements of FDA. The national environmental protection department is currently investigating and further understanding the performance of the company's PVDC film

it is reported that at present, consumers and food enterprises do not know much about PVDC film. In addition to the general properties of plastics, this high barrier material also has good oxygen, gas and odor resistance and excellent moisture and mildew resistance. It is a material with relatively good comprehensive barrier properties of plastic packaging in the world today. In the past, it was replaced by PVC thin film due to cost reasons. But lichengxin said that at present, the use of this film should not add any burden to consumers
