- 3. The wrapping material of claim 1, wherein the coating pattern comprises transverse bands of coating layers, each band having a longitudinal width and spaced apart along a longitudinal length of the wrapping material.
- 4. The wrapping material of claim 1, wherein the coating layers comprise coatings applied in pre-determined amounts.
- 5. The wrapping material of claim 1, wherein the coating layers are applied to the substrate online during the making of the smoking article.
- 6. A wrapping material suitable for making a smoking article, the wrapping material comprising:
a smoking article wrapping material substrate having a plurality of bands of coating layers deposited in a pattern on the substrate, at least one of the coating layers applied by ink jet coating.
- 7. The wrapping material of claim 6, wherein the wrapping material is adapted to be useful in manufacture of a reduced ignition propensity cigarette.
- 8. The wrapping material of claim 6, wherein the coating pattern comprises transverse bands of coating layers, each band having a longitudinal width and spaced apart along a longitudinal length of the wrapping material.
- 9. The wrapping material of claim 6, wherein the coating layers comprise coatings applied in predetermined amounts.
- 10. The wrapping material of claim 6, wherein the coating layers are applied to the substrate online during the making of the smoking article.
- 11. A smoking article having reduced ignition propensity, the smoking article comprising a smokable material disposed in a wrapping material, the wrapping material comprising:
a smoking article wrapping material substrate having a plurality of bands of coating layers deposited in a pattern on the substrate, at least one of the coating layers applied by spraying, wherein each of the plurality of bands comprises (a) a first coating layer effective in reducing the inherent porosity of the substrate, and (b) a second coating layer overlying the first coating layer.
- 12. A smoking article having reduced ignition propensity, the smoking article comprising a smokable material disposed in a wrapping material, the wrapping material comprising:
a smoking article wrapping material substrate having a plurality of bands of coating layers deposited in a pattern on the substrate, at least one of the coating layers applied by ink jet coating, wherein each of the plurality of bands comprises (a) a first coating layer effective in reducing the inherent porosity of the substrate, and (b) a second coating layer overlying the first coating layer.
- 13. A method of making a smoking article wrapping material, the method comprising:
providing a smoking article wrapping material substrate wound on a first roll; unwinding the substrate from the first roll; applying in a pattern on the substrate a plurality of bands of coating layers comprising (a) a first coating layer effective in reducing the inherent porosity of the substrate, and (b) a second coating layer overlying the first coating layer, at least one of the coating layers applied by spraying.
- 14. The method of claim. 13, wherein the bands of coating layers are applied to the substrate online during making of a smoking article.
- 15. The method of claim 13, further comprising winding the wrapping material substrate onto a second roll,
wherein the bands of coating layers are applied to the substrate offline prior to making of a smoking article.
- 16. A method of making a smoking article wrapping material, the method comprising:
providing a smoking article wrapping material substrate wound on a first roll; unwinding the substrate from the first roll; applying in a pattern on the substrate a plurality of bands of coating layers comprising (a) a first coating layer effective in reducing the inherent porosity of the substrate, and (b) a second coating layer overlying the first coating layer, at least one of the coating layers applied by ink jet coating.
- 17. The method of claim 16, wherein the bands of coating layers are applied to the substrate online during making of a smoking article.
- 18. The method of claim 16, further comprising winding the wrapping material substrate onto a second roll,
wherein the bands of coating layers are applied to the substrate offline prior to making of a smoking article.
