Viskase (formerly Visking) is a global corporation based out of Darien, Illinois, USA that supplies plastic, cellulose, and fibrous film and packaging to the food service industry, including casings for processed meats such as hot dogs and sausages. Viskase has manufacturing facilities in the United States, Mexico, Brazil and France, as well as sales offices located around the world.
Edwin O. Freund founder of what would become Viskase sought a readily available replacement for animal intestine casing. Upon creating a cellulose casing, using the "viscose" process (also used in rayon) he realized the product stuffed well, linked, and was able to withstand the smokehouse. Quite by accident, he discovered that when the casing was removed from the product the sausages retained their shape and were firm. This was the beginning of the skinless frankfurter or hot dog.
