Can be used, casings are mainly used as outer coatings for stuffed sausages and enemas; sheep casings can also be made into catgut, which is used to make tennis racket strings, bow strings and surgical sutures.

Casings are divided into pig casings, sheep casings and cattle casings according to animal types. According to the parts, they are divided into large casings and small casings. The intestine is divided into 4 layers from the inside out: mucosa, submucosa, muscularis and serosa. According to the different requirements of animal types and processed products, the processing of the upper four layers is also different. Good quality casings should be tough and translucent. What is emerging now is collagen edible casings.

Extended information:

There is no unified understanding in China regarding the determination of casing membrane thickness. With reference to several major foreign casing processing manufacturers and our own test results, 50um is a more reasonable thickness design when the structure is reasonable and the materials are scientifically selected. At this thickness, the barrier properties, mechanical strength, and cost performance of the casing can achieve an excellent combination.

Too thin will have a certain impact on performance, and too thick will increase the customer's cost of use. For example, for a transparent casing with a folding diameter of 90mm, if it is designed with a thickness of 50um.

1kg of casings can produce 110m. If designed with a thickness of 60um, 1kg of casings can only produce 96m. The difference between the two is 14m. The difference is about 12, in other words, it is a loss of 12 packaging costs. From an economic perspective, the latter is uneconomical for users.
