A multi-ply paper product, such as linerboard, composed of a base ply of Kraft pulp and a top ply of reclaimed, white office waste paper which contains fillers, such as clay and calcium carbonate, toners and ink. A dry strength additive, such as cooked starch, is incorporated in the plies and serves to improve the internal strength of the top ply, as well as improving the bond between the plies.
