Abstract
Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials include coatings in the form of series of spaced apart bands, each band having a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer. Flavoring agent(s) are included in one or more of the wrapping material itself, a seam adhesive, and/or bands included on the wrapping material.
