A tough translucent film made by scraping the large and small intestines of livestock. It is divided into pig casings, sheep casings and cattle casings according to animal types, and can be divided into small casings and large casings. It is mainly used as a coat for filling sausages and enema; sheep casing can also be made into gut for making tennis racket string, bow string, instrument string and surgical suture, etc. China has been processing casings for more than a hundred years. Pig casings are mostly produced in Eastern and Central China; sheep casings are mostly produced in North China, Northeast China and Inner Mongolia. Initially it was only used for bowstrings and cotton strings, and the output was limited. At the beginning of the 20th century, factories were set up in Tianjin, Beijing and other places for processing and production, which soon became an important export material for China. \"Constitution\" The intestine can be divided into four layers: mucosa, submucosa, muscle layer, and serous membrane from the inside to the outside. When processing the salt casings of pigs and sheep, only the submucosa is left and the other 3 layers are scraped; when processing the dry casings of pigs and sheep, part of the mucosa is retained in addition to the submucosa; when processing salt and dry casings of cattle, only the mucosa is removed and Read More

The rationality of casing structure: The reasonable structure design of casing can provide an ideal packaging for sausages. 3. Casing film strength: good mechanical strength can meet the requirements of various filling and punching machines, thereby reducing the loss of casing film during use. 4. The stability of the shrinkage rate: refers to the consistency of the shrinkage rate of the same roll or the same batch of casings. If the shrinkage rate fluctuates greatly, the length and thickness of the sausage of the same specification will be uneven, which will be boxed and sold for you A lot of trouble. 5.
