Fibrous Casings are synthetic and inedible, we stock this product as an alternative to Natural Casing and they are primarily used for Salami, Pepperoni, Cacciotorie and can be used for many continental sausages. The Fibrous Casings consist of cellulose which is then applied to a special paper which has exceptional strength. All Fibrous Casings are clipped at one end and come with a length of string attached for hanging.
