Abstract

A molded pulp product formed from the molding of a three-dimensional pulp slurry. The pulp slurry comprises a natural fiber composition of virgin fibers which have not been recycled and are derived from plant materials. The natural fiber composition includes hemp fibers which have been micronized to suitable length and combined with pulverized hemp shive to form a fibrous matrix. The molded pulp product is formed from a vacuum molding process, thermoforming process, custom air-burst molding process, or other molding process wherein the slurry is applied to a three-dimensional mold and a three-dimensional product is formed. The resulting packaging product is one hundred percent biodegradable.
