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, 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.
An article of manufacture comprising an inorganically filled matrix including a substantially homogenous mixture of organic binder and aggregate, the matrix having a coating on at least a portion thereof such that the matrix is substantially nonporous and having a thickness in a range from about 0.01 mm to about 1 cm, the matrix comprising:
An article of manufacture comprising an inorganically filled matrix including a substantially homogenous mixture of organic binder and inorganic aggregate, wherein the matrix has a coating on at least a portion thereof, degrades after prolonged exposure to water, and has a thickness in a range from about 0.05 mm to about 1 cm, wherein the organic binder is selected from the group consisting of polysaccharides, proteins, and mixtures or derivatives thereof and has a concentration in a range from about 1% to about 60% by volume of total solids in the inorganically filled matrix, wherein the inorganic aggregate has a concentration in a range from about 30% to about 90% by volume of total solids in the inorganically filled matrix, and wherein the inorganically filled matrix further includes a fibrous material substantially homogeneously dispersed therein and having a concentration in a range from about 0.5% to about 60% by volume of total solids in the inorganically filled matrix.
An article of manufacture comprising an inorganically filled matrix including a substantially homogenous mixture of organic binder and aggregate, the matrix having a coating on at least a portion thereof and having a thickness in a range from about 0.01 mm to about 1 cm, the matrix formed by removing a significant quantity of water by evaporation from the inorganically filled mixture comprising:
