Abstract
In one embodiment, the present invention provides a method of forming a cellulose article having a specific volume of less than 3 cc/gm. The method includes the step of incorporating cellulose fibers with a compound, wherein the compound includes an aqueous dispersion. The aqueous dispersion may have at least one polymer selected from the group consisting of an ethylene-based thermoplastic polymer, a propylene-based thermoplastic polymer, and mixtures thereof; at least one polymeric stabilizing agent; and water. In certain embodiments, a combined amount of the at least one polymer and the at least one stabilizing agent comprises about 25 to about 74 volume percent of the aqueous dispersion.
