Abstract
A method including improving a property of a paper product precursor by adding a molten wax suspension to paper product precursor, the molten wax suspension including a suspension of liquid wax particles in a liquid solvent, the liquid wax particles being at a temperature higher than the melting point of the wax. The molten wax suspension may be added to the paper product precursor in a production line prior to making a finished paper product. A finished paper product may be made from the paper product precursor.
