The present disclosure provides a composite substrate configured for use in aerosol generating components for aerosol delivery devices. The composite substrate includes a first substrate material and a second substrate material attached thereto. The first substrate material includes a first filler, a first binder, and a first aerosol forming material, and the second substrate material includes a second filler and a second binder. Further provided are a process for making the composite substrate, and aerosol generating components and aerosol delivery devices including the composite substrate. Such devices utilize electrically generated heat or combustible ignition sources to heat the composite substrate, providing an inhalable substance in the form of an aerosol.

The present invention relates to a casting apparatus for the production of a cast web of homogenized tobacco material, said casting apparatus comprising • o a casting box (4) adapted to contain a slurry of said homogenized tobacco material; • o a movable support; • o a casting blade (6) adapted to cast the slurry contained in the casting box onto the movable support so as to form the cast web; • o wherein said casting blade has a transverse cross section defining a blade edge, said blade edge including a first point having a first radius of curvature and a second point having a second radius of curvature, said first and second radii of curvature being comprised between about 1 and about 500 and being different from each other.

There is provided a method of extracting one or more volatile compounds of interest from tobacco material, the method comprising the steps of:

i) providing tobacco material;
ii) subjecting the tobacco material to steam distillation; and
iii) extracting one or more volatile compounds of interest from the tobacco material with a solvent;
wherein distillation step (ii) and extraction step (iii) are carried out simultaneously and at a pH of no greater than 2, and wherein the period during which both the distillation step (ii) and the extraction step (iii) are carried out is from about 8 to about 20 hours.

A wrapping material for a smoking article is formed from a web that includes extracted pieces of cannabis combined with web building fibers. The web has a basis weight of from about 20 gsm to about 80 gsm and a permeability of from about 10 Coresta to about 100 Coresta. The wrapping material has a natural cannabis smell and taste. The wrapping material is tobacco and nicotine free and can be used as a carrier for flavorings or aerosol delivery compositions.

The present disclosure relates to a flavor delivery device and a cartridge that includes such flavor delivery device. The flavor delivery device includes a flavor substrate that can be formed of a porous material, and further including flavor material included within the flavor substrate. The flavor substrate is surrounded by an outer sleeve which is impermeable to the flavor material. The flavor delivery device may be positioned within a cartridge of an aerosol delivery device where the flavor delivery device is located downstream from a reservoir containing an aerosol precursor composition relative to the mouthend of the cartridge.

The invention relates to a bulk solid reconstituted plant composition, the volume of which is suitable for devices that heat tobacco without burning it, said bulk solid composition comprising a plant extract, refined plant fibres and an aerosol-generating agent.

Abnormally-shaped tobacco granules are provided. The tobacco granules comprise a tobacco granule body and a coating attached to the surface of the tobacco granule body. The coating contains an adhesive. The surface of the abnormally-shaped tobacco granule has one or more grooves and/or ridges, and/or, the abnormally-shaped tobacco granule has through holes therein. The surface grooves of the abnormally-shaped tobacco granules can serve as smoke channels after the tobacco granules are bonded, cured and shaped, so that the air permeability inside a total-granule tobacco product is greatly improved. The smoking resistance of cigarettes is reduced. The flammability of cigarettes is improved and the consumption of tobacco raw materials is reduced. A preparation method of the abnormally-shaped tobacco granules, a tobacco product comprising the abnormally-shaped tobacco granules, and a preparation method thereof are also provided.
