Abstract of the Disclosure Fibrous sheet material for use in the manufacture of food casings and the like employs a specific bonding system that comprises an initial treatment with a solution containing thermoplastic materials such as poly(vinyl alcohol) and a subsequent treatment with a combined film forming material and an insolubilizing agent for the film forming material. The treatment with poly(vinyl alcohol) is effective to impart high alkaline or caustic strength to the sheet material while the second treatment is effective to impart high wet strength to the first treated material without substantially reducing the alkaline strength thereof. It is necessary that the two step treatment be conducted in the specific order indicated in order to achieve the appropriate combination of features that include high dry strength and alkaline strength coupled with high wet strength and absorption.
