Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a highly inorganically filled matrix. Suitable inorganically filled mixtures are prepared by mixing together an organic polymer binder, water, one or more aggregate materials, fibers, and optional admixtures in the correct proportions in order to form an article which has the desired performance criteria. The inorganically filled mixtures are molded to fashion a portion of the mixture into a form stable shape for the desired article. Once the article has obtained form stability, such as by heating to remove water by evaporation, the article is removed from the mold and allowed to harden to gain strength. The articles may have properties substantially similar to articles presently made from traditional materials like paper, paperboard, polystyrene, plastic, or metal. They have especial utility in the mass production of containers, particularly food and beverage containers.

[ What is claimed and desired to be secured by United States Patent is:] [1.] An inorganically filled composition comprising:water having a concentration in a range from about 10% to about 80% by weight of the inorganically filled composition;a water-dispersible organic binder selected from the group consisting of polysaccharides, proteins, water-soluble polymers, derivatives of the foregoing, and mixtures of the foregoing, the organic binder having a concentration in a range from about 5% to about 80% by weight of total solids in the inorganically filled composition;an inorganic aggregate having a concentration in a range from about 20% to about 95% by weight of total solids in the inorganically filled composition; anda fibrous material substantially uniformly dispersed throughout the inorganically filled composition,wherein the inorganically filled composition and the binder are substantially unfoamed.
