Our Collagen casing is fabricated from collagen, which is obtained from the curium layer of selected split cattle hides. The collagen-rich tissue is homogenized under high pressure, ring-extruded (hose-shaped) and hardened and results in a mechanically strong casing.
Plastic casings are extruded like most other plastic products. They also can be flat or shirred. Generally, smoke and water do not pass through the casing, so plastic is used for non-smoked products where high yields are expected.
