MULTI-PLY CELLULOSIC PRODUCTS USING HIGH-BULK CELLULOSIC FIBERS

摘要

A multi-ply paparboard comprising at least one ply of conventional cellulose fibers and from about 0.1 to about 6 weight percent of a water-borne binding agent; and at least one ply of chemically intra-fiber crosslinked cellulosic high-bulk fibers and from about 0.1 to about 6 weight percent of a water-borne binding agent. The water-borne binding agent may be a starch, a modified starch, a polyvinyl alcohol, a polyvinyl acetate, a polyethylene/acrylic acid copolymer, an acrylic acid polymer, a polyacrylate, a polyacrylamide, a polyamine, guar gum, an oxidized polyethylene, a polyvinyl chloride, a polyvinyl chloride/acrylic acid copolymer, an acrylonitrile/styrene copolymer or polyacrylonitrile. A method for making the paperboard.
