FIELD: articles, methods and equipment for their manufacture. SUBSTANCE: invention includes manufacture of sheets having matrix filled with numerous inorganic substances produced by mixing of organic polymer binder, water, one or more inorganic aggregate materials, fibers and selected additional mixtures in preset proportions to obtain sheet with preset properties. Mixtures with inorganic substances are formed into sheets by the first extrusion of mixture and subsequent passing of extruded material through rolls. Sheets rolled by rolls are dried by accelerated method to obtain hardened sheet by rolling with hot rollers and/or in drying chamber. Sheets containing inorganic substances may have properties essentially similar to sheets manufactured from traditional such as paper, cardboard, polystyrene, plastic and metal. Such sheets may be rolled, pressed, marked, perforated, bent or cemented. Particularly, these sheets are applicable in mass manufacture of such articles as food containers and containers for beverages, and as packing materials. EFFECT: manufactured ecologically safe high-quality material and articles. 191 cl, 26 dwg
