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.

Hydrophobic plug wrap

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.

Hydrophobic smoking article tube

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

Hydrophobic wrapper

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.

Smoking article having a particle containing wrapper

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.
