Abstract: A smoking article includes a tobacco substrate and a filter segment comprising filtration material axially aligned in an abutting end to end relationship with the tobacco substrate. A hydrophobic plug wrap is disposed about the filtration material. The plug wrap is hydrophobic via hydrophobic groups chemically bonded to the plug wrap.

Abstract: An aerosol-generating article for producing an inhalable aerosol upon heating is provided, the aerosol-generating article including: a rod of aerosol-generating substrate, the aerosol-generating substrate including homogenised plant material including tobacco particles and at least 2.5 percent by weight of non-tobacco plant flavour particles, on a dry weight basis, the non-tobacco plant flavour particles including particles of eucalyptus, star anise, clove, ginger, rosemary, or combinations thereof; an upstream element upstream of the rod of aerosol-generating substrate and abutting an upstream end of the rod of aerosol-generating substrate; and a downstream section arranged downstream of the rod of aerosol-generating substrate and in axial alignment with the rod of aerosol-generating substrate, the downstream section including one or more downstream elements.

Abstract: A smoking article tube includes an elongated tube having a mouthpiece segment at a first end and an empty smokable material cavity defined by a second end of the elongated tube opposing the first end. A hydrophobic tube region includes hydrophobic groups covalently bonded to the elongated tube.

Abstract: A smoking article (10) includes a tobacco substrate (20) comprising at least 15% humectant and a hydrophobic paper wrapper (40) disposed about the tobacco substrate. The paper wrapper (40) is hydrophobic due to hydrophobic groups covalently bonded to the paper.

Abstract: A smoking article includes a tobacco rod and a wrapper disposed about the tobacco rod. The wrapper includes a plurality of aggregated particles. The aggregated particles include particles of functional material and a whitener bound in a polymeric binder. The particles of functional material may be a catalyst or an oxidant, such as an iron oxide-containing particle. The whitener may be calcium carbonate.

Abstract: A smoking article includes a tobacco substrate and a wrapper disposed about the tobacco substrate. At least an inner or outer surface of the wrapper is hydrophobic via hydrophobic groups chemically bonded to the wrapper. The wrapper has a permeability of at least about 15 CORESTA units.
