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.

A smoking article including a heat resistant sheet material comprising a fibrous layer formed of cellulosic fibers and at least 50% by weight of an inorganic filler material having a particle size in the range of from about 0.1 microns to about 50 microns, wherein the sheet material has a tensile strength ranging from about 1300 N/m to about 6000 N/m and a thickness ranging from 70 microns to 200 microns, and wherein the fibrous layer further includes a binder material and the binder constitutes about 0.5% to about 5% by weight of the fibrous layer.
An electrically heated smoking article configured to generate an aerosol, the electrically heated smoking article comprising:
- an aerosol-generating substrate;
- a carrier formed of a heat resistant sheet material, the heat resistant sheet material comprising a fibrous layer formed of cellulosic fibers and at least 50% by weight of an inorganic filler material having a particle size in the range of from about 0.1 microns to about 50 microns, wherein the sheet material has a tensile strength ranging from about 1300 N/m to about 6000 N/m and a thickness ranging from about 70 microns to about 200 microns, and wherein the fibrous layer further includes a binder material and the binder constitutes about 0.5% to about 5% by weight of the fibrous layer.
