The invention provides a three layered reprographic paper having improved strength, stiffness and curl resistance properties, and a method for making same. The paper has a central core layer made largely of cellulose and bulked with a bulking agent such as a diamide salt. A starch-based metered size press coating is pressed on both sides of the core layer, wherein the starch has a high solid content. The coating forms a three layered paper having an I-beam arrangement with high strength outer layers surrounding a low density core.

Paper with improved stiffness and bulk and method for making same

A substrate comprising a paper layer and at least one biodegradable polymer layer extruded thereon is provided. The paper layer may have an extruded polymer layer on each side, it may have multiple polymer layers extruded on one side, or both. Additives appropriate for the particular use of the substrate may be added to one or more of the polymer layers.
