Abstract (en)
A smoking article comprises a paper wrapper comprising at least one area 5 of fibrous add-on material containing between about 5 percent and about 15 percent calcium carbonate by weight of the fibrous material. The permeability of the base web 3 outside the area of add-on material is between about 25 Coresta units and about 90 Coresta units and the permeability of the base web in the areas of add-on material is below about 10 Coresta units. A method of applying at least one area 5 of add-on material to a base web 3 comprises forming a base web from a slurry of fibrous material in a liquid and applying at least one area of add-on fibrous material containing between about 5 percent and about 15 percent calcium carbonate by weight of the fibrous material to the base web, reducing the permeability in the areas of add-on material below about 10 Coresta units and drying the base web with the add-on material thereon.
