Abstract
A smoking article includes a sheet material including a fibrous layer formed of cellulosic fibres and at least 50% by weight of inorganic filler material having a particle size in range of from 0.1 microns and 50 microns, wherein the sheet material has a tensile strength of at least 900 N/m. The fibrous layer includes a binder material, such as an organic binder material. The organic binder material can be a cellulosic binder material. A coating layer may be provided on at least one side of the fibrous layer.
