ABSTRACT:
A multi-ply paper product, such as linerboard, composed of a base ply of Kraft pulp and a top ply of de-inked, reclaimed newsprint. A dry strength additive, such as cooked starch, is incorporated in the plies and serves to improve the internal strength of the top newsprint ply, as well as improving the bond between the plies.
