1) PVDC casing film is mainly used for packaging ham sausage, high temperature resistance and sterilization. It is suitable for industrialized mass production of ham sausage on high-frequency welded automatic enema machine. China has become the region with the largest consumption of PVDC casing film. Now, PVDC casing film is used in the packaging of high-temperature ham sausage in China, and the product retention period can reach more than 6 months. China's Shuanghui group has done quite well in this regard.
