A method for making a packaging material includes jetting a first pulp stock onto a wire to form a strength layer precursor including water; and softwood fibers, the first pulp stock excluding a water soluble di-valent or multi-valent salt. A second pulp stock is jetted onto a second wire to form an image layer precursor including water; hardwood fibers; and a water soluble di-valent or multi-valent salt present in an amount ranging from about 5 lb per ton of total fibers in the second pulp stock to about 50 lb per ton of the total fibers in the second pulp stock. The image layer precursor and the strength layer precursor are placed in contact. Water is removed from the image and strength layer precursors. The image layer precursor and the strength layer precursor are dried to form the packaging material including an image layer and a strength layer.
