Abstract From the Canadian patent

Packaged fibrous and non-fibrous reinforced food casings containing sufficient water that presoaking prior to stuffing can be eliminated. The casings which rely on water as the sole or principal plasticizes do not rely on chemical type plasticizers like glycerin and propylene glycol. The premoisturized ready-, to-stuff casings are preserved with effective amounts of a high pH active antimycotic agent. Drying requirements can be reduced or eliminated.
