The fabric can have a basis weight of less than 30 gsm and a tensile strength of at least 4 mJ in at least one predetermined direction. Method of making the fabric can include melt-blowing a polymeric material against a support surface and bonding the fibers or arranging them in a predetermined orientation. Pouched smokeless tobacco or tobacco substitute products including the fabrics provided herein can provide desirable flavor and tactile experience.

An aerosol-generating film having a tobacco content of less than 1 percent by weight is provided, the aerosol-generating film including: a cellulose based film-forming agent; a non-cellulose based thickening agent; water; nicotine; and a polyhydric alcohol, a content of cellulose based film-forming agent being at least about 14 wt percent weight and less than or equal to about 26 wt percent, and a content of water being less than about 30 wt percent and a content of polyhydric alcohol is at least about 30 wt percent.

A method of preparing a whitened tobacco material for use in a smokeless tobacco product is provided, including: (i) extracting a tobacco material with an extraction solution to provide a tobacco solids material and a tobacco extract; (ii) cooking the tobacco solids material in an alkaline sulfite cooking liquor including sulfite ions and having a pH of greater than 7 to form a tobacco pulp; (iii) bleaching the tobacco pulp with a bleaching solution to provide a bleached tobacco material; and (iv) drying the bleached tobacco material to provide the whitened tobacco material.

A consumable for an aerosol provision system comprising at least one substrate material in proximity to at least one drying agent. The drying agent preferably includes a sorbent, e.g., a desiccant, a wicking material or a mixture thereof. Also provided is a pod for an aerosol provision system where the pod contains the consumable and the consumable is configured to receive an aerosol, and use of a drying agent to increase consistency or yield of volatile compound delivery from a substrate material in an aerosol provision system.

The present invention provides a gel aerosol-forming substrate cartridge that can be inserted into an electrically heated smoking article, the gel aerosol-forming substrate cartridge comprising: a gel aerosol-forming substrate containing glycerin and gelatin, which exists in gel form, semi-solid form, or solidified form in a first temperature range including room temperature, changes to a liquid form in a second temperature range including 70° C., and is vaporized into an aerosol in a temperature range of 150 to 400° C.; a gel receptor that receives the gel aerosol-forming substrate; and wrapping paper wrapped around the side of the gel receptor in a cylindrical shape measuring 7 to 20 mm long and 5 to 8 mm in diameter, and also provides an electrically heated smoking article comprising: a filter; the gel aerosol-forming substrate cartridge located upstream of the filter; and a tobacco filler containing shredded tobacco located upstream of the filter and located upstream or downstream of the gel aerosol-forming substrate cartridge, wherein the filter, gel aerosol-forming substrate cartridge, and tobacco filler are wrapped in wrapping paper to form a cigarette.

A tobacco composition comprising a tobacco component and an aerosol forming material, wherein the tobacco component comprises leaf tobacco material in an amount of between about 10% and about 90% by weight of the tobacco component and wherein the leaf tobacco material has a nicotine content of greater than 1.5% by weight of the leaf tobacco material and a method of making the tobacco composition. Also, an article comprising the tobacco composition for use in an aerosol provision system and a system comprising a device arranged to heat the tobacco composition and generate an aerosol from the tobacco composition.

A pouched product adapted for release of a releasable component therefrom is provided herein. The pouched product can include a water-permeable fabric pouch formed so as to define a cavity therein, and a composition contained within the cavity of the water-permeable fabric pouch, the composition including one or more releasable components that are released from the composition under mouth conditions and that are capable of movement through the water-permeable fabric pouch. The composition includes nicotine and at least one particulate non-tobacco material. The pouched product also includes at least one capsule contained within the cavity of the water-permeable fabric pouch, the capsule having a capsule wall surrounding an inner payload comprising at least one botanical.

An atomizing liquid gel with reversible phase transition characteristics includes: a sugar-based gelling agent, 0.1-3.0 wt %; an atomizing liquid, 97.0-99.9 wt %; a molecule of the sugar-based gelling agent is a sugar molecule introduced with an amide group and/or an aryl group, and the sugar molecule optionally further includes at least one hydrophobic structural part selected from —C.sub.xH.sub.y, —O—C.sub.xH.sub.y and ##STR00001##
and x>2 and y>2. The atomizing liquid gel has characteristics of thermal reversible phase transition and/or shear reversible phase transition, a temperature of gel-sol phase transition is 100° C.-248° C., and a critical shear stress of the gel-sol phase transition is 40-800 Pa. Under heating and/or oscillation, the atomizing liquid gel converts from the gel state to a sol state, and the atomizing agent fixed in the gel releases to form an inhalable aerosol. When the heating and/or oscillation are stopped, the atomizing liquid gel is quickly recovered from the sol state to the gel state, and the unatomized atomizing agent is refixed in the gel. The use of the atomizing liquid gel solves the problem of liquid leakage of the liquid nicotine of the atomizer caused by the smoke condensate after the smoking stops, the change of air pressure or the action of external force during transportation.

An aerosol generating article includes a first portion including an organic acid, a second portion including a nicotine freebase, a third portion including a cooling material, and a fourth portion including a filter material, wherein a nicotine salt is generated through an acid-base reaction of the organic acid and nicotine freebase that are vaporized by heating.

Methods for encasing bodies including smokeless tobacco or a tobacco substitute with a polymeric casing can include coating a compressed body with microfibers, applying tubular casings to compressed bodies, printing netting and webs on compressed bodies, injection molding around compressed bodies, applying a webbing to compressed bodies, placing compressed bodies into a skin forming bath, and including thermoplastic polymers in a compressed body.
