Compositions, methods and systems for manufacturing articles, including containers and packaging materials, from hydraulically settable and inorganically filled materials are disclosed. Suitable compositions are prepared by mixing together a hydraulically settable binder or organic binder, water, and appropriate additives, such as aggregates, fibers, and rheology-modifying agents, which impart predetermined properties so that an article formed therefrom has the desired performance criteria. The desired article can be molded from the mixture using a variety of moding processes including: die pressing, injection molding, blow molding, jiggering, wet sheet molding, and dry sheet molding. The sheet forming pro cesses require the mixture to first be fashioned into a sheet, such as by the use of an extruder (12) or rollers, after which the sheet is formed, it is hardened. Printed indicya and a coating can then the applied. |
