Edible casings are made from animal skins (such as collagen fibers from the dermis of cows and pigs), and their properties are similar to natural casings. We call them collagen casings, which are characterized by breathability and edible properties. They have a semi transparent beige color, a seamless tube shape, and no perforations. This is the only edible type of artificial casings. Edible, but not suitable for coarse ingredients; Good breathability and easy coloring.
