Abstract:
    Co-extruded smokable material in sheet-like form has a multi-layered structure. The layers are generally parallel to the major surface of the material. The material is provided by subjecting at least two filler materials to high shear agitation and co-extruding the materials while in a semi-soft state. The multi-layered material can be sized by roll treatment in order to provide a sheet-like material having a thickness of less than about 0.008 inch. The material so provided can be cut into small sheets, e.g., about 4 inches by 4 inches square, or into strands and employed as cut filler in the manufacture of cigarettes.
