Abstract
A wrapper of a smoking article comprising a base web and banded regions comprising a leading edge, a trailing edge and a plurality of add-on material-free openings between said leading edge and said trailing edge. The add-on material-free openings establish a predetermined, nominal opened-area within said banded regions to control diffusivity. The add-on material can be applied by a gravure roller comprising a surface region with cells, cell-free areas and a chevron shape.
Claims19
A method of manufacturing wrapper material suitable for forming wrappers of smoking articles, comprising maintaining a heated aqueous starch solution at a temperature sufficient to provide the aqueous starch solution with a viscosity of less than about 200 cP, feeding a base web along a feed path, and printing the aqueous starch solution onto the base web such that a plurality of banded regions of add-on material formed by the aqueous starch solution are applied to the base web, each of the banded regions comprising a leading edge and a trailing edge and add-on material-free openings between the leading edge and the trailing edge, the openings establishing a predetermined, nominal opened-area within each of the banded regions in the range of about 4% to about 9% of a total nominal area of each of the banded regions.
