Definitions

  • the fibrous crystalline cellulosic material is in a condition of having been gravure printed on the base web as a fibrous crystalline cellulosic slurry that comprises water, crystalline cellulose, and chalk wherein the fibrous crystalline cellulosic slurry has a solids content of about 10% or less by weight of the fibrous crystalline cellulosic slurry.
  • the tobacco rod 122 has a lightable or lit end 124 and a tipped end 130, which, in the case of non-filtered cigarettes, is referenced as the mouth end 130 of the smoking article 120. Cut filler tobacco is an industry-standard designation.
  • the tobacco rod 122 has a generally circular cross section. In other example embodiments, the tobacco rod 122 can have an oval cross section or other non-circular shape cross section.
  • the wrapper 123 is sealed along a longitudinal seam to form the tobacco rod 122.
  • the base web 140 has a permeability greater than about 60 CORESTA with a basis weight of about 25 gsm or more, a permeability greater than about 80 CORESTA with a basis weight of about 25 gsm or more, or a permeability greater than about 100 CORESTA with a basis weight of about 25 gsm or more in regions outside of the banded regions of fibrous crystalline cellulosic material 126.
  • application of the fibrous crystalline cellulosic slurry to a base web 140 and drying thereof forms a banded region of fibrous crystalline cellulosic material 126 on the base web 140 that is effective to locally reduce the permeability of the base web 140 within the banded region 126.
  • bands of fibrous crystalline cellulosic slurry are printed on the base web 140 with a gravure roller 610 to reduce the permeability of the base web 140 within the banded regions of fibrous crystalline cellulosic material 126 to about 0 to about 12 CORESTA.
  • the permeability of the base web 140 within the banded regions of fibrous crystalline cellulosic material 126 is 7 CORESTA or less.
  • application of the fibrous crystalline cellulosic slurry to the base web 140 and drying thereof forms a banded region of fibrous crystalline cellulosic material 126 on the base web 140 that is effective to locally reduce diffusivity values of the base web 140 from a diffusivity level of about 2 cm/sec or greater (for the base web 140 in regions free of added fibrous crystalline cellulosic material) to a value in the range of 0.0 to about 0.2 cm/sec as measured by a Sodim CO 2 Diffusivity Tester (purchased from Sodim SAS of France).
  • the fibrous crystalline cellulosic material is free of any binders and modified cellulose. In an example embodiment, the fibrous crystalline cellulosic material is free of any bacterial cellulose. In an example embodiment, the fibrous crystalline cellulosic material is microcrystalline cellulose and is free of any binders and modified cellulose. In an example embodiment, the fibrous crystalline cellulosic material is microcrystalline cellulose and a binder.
  • the fibrous crystalline cellulosic slurry is a composition having less than about 5% solids wherein a ratio fibrous crystalline cellulosic material to chalk in the fibrous crystalline cellulosic slurry is about 94.5 to 5.5. In an embodiment, the fibrous crystalline cellulosic slurry is a composition having about 2% solids wherein a ratio fibrous crystalline cellulosic material to chalk in the fibrous crystalline cellulosic slurry is about 94.5 to 5.5.
  • Self-Extinguishment or SE herein is a reference to smoldering characteristics of a smoking article under free burn conditions.
  • SE Self-Extinguishment
  • a laboratory test is conducted at a temperature of 23° C +- 0.3° C and relative humidity of 55% +- 0.5%, both of which should be monitored by a recording hygrothermograph. Exhaust hood(s) remove combustion products formed during testing.
  • smoking articles to be tested Prior to testing, smoking articles to be tested are conditioned at 55% +-0.5% relative humidity and 23° C +- 0.3° C for 24 hours. Just prior to testing, the smoking articles are placed in glass beakers to assure free air access.
