A cellulose wrapper for a smoking article includes a cover layer and at least one inner layer. The cover layer has an area weight of 20 to 60 g/m2, a raw density of 0.5 to 0.9 g/cm3, an air permeability of 10 to 250 CU, a filler material content in the range of 10 to 60 percent, and a burn promoting salt content in the range of 0 to 5 percent. The inner layer has an area weight of 6 to 20 g/m2, a raw density of 0.7 to 1 g/cm3, and an air permeability of 0 to 12 CU. The layers are wet laminated in a paper machine. Smoking articles with such a wraper do not experience a change in taste of the main smoke flow nor any spot development, and they afford an attractive ash tube or sheath. The time period for extinguishing the smoking article can be varied within wide limits. Moreover a drastic reduction of secondary smoke flow can be noted.
