Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having wrapping paper having additive materials applied thereto as patterns. The additive materials, which can include a starch and/or a polymer, are applied to a continuous paper web either online or offline the cigarette making apparatus. The formulation can be applied to the paper web using application apparatus possessing a series of rollers. In particular, a wrapping paper for a smokable rod can include a pattern of bands having a water-insoluble material comprising a starch ester, a starch-coated inorganic filler, and/or a thermoplastic polymer in an amount such that the material is sufficiently deformable so as to (a) reduce an amount of pressure to apply the bands, (b) decrease paper diffusivity, and (c) maintain paper opacity at a level acceptable for commercial production of the smokable rods.
