A hinge for use in inorganically filled composite materials is provided. The hinge has an inorganically filled structural matrix comprising a water-dispersable organic polymer binder, an aggregate material, and a fibrous material. The hinge allows inorganically filled materials to be bent along a line without breakage of the material. The hinge is preferably formed by scoring a formed sheet of inorganically filled material. The hinge is particularly useful in containers that require bending of various container parts, such as in food containers and boxes made from inorganically filled materials.
