    Abstract: A moisture barrier paper is comprised of a fiber mat and a unique moisture barrier coating. The moisture barrier coating coats substantially every fiber throughout the fiber mat. The moisture barrier paper is created in a wet-end, on-machine process where a liquid, moisture barrier coating is sprayed onto a forming fiber mat and is drawn through the fibers with vacuum. The moisture barrier paper has top and bottom surfaces that are substantially free of wax and polymeric water repellants. The moisture barrier paper is completely repulpable.
