摘要： A wrapper of a smoking article comprising a base web and banded regions comprising a leading edge, a trailing edge and a plurality of material-free openings between said leading edge and said trailing edge. The 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.

摘要： A smoking article (120) includes a tobacco rod (122) comprising a column of filler and a wrapper (123) surrounding the column of filler. The tobacco rod (122) has a circumferential direction, a longitudinal direction (142), a lit end (124), and a mouth end (130). The wrapper (123) includes a base web (140) having generally parallel first and second side edges extending in the longitudinal direction (142) and two ends extending in the circumferential direction wherein the base web (140) is disposed around the column of filler such that the first and second side edges of the base web (140) overlap and form a seam. The base web (140) includes at least one circumferentially extending banded region (126) of fibrous crystalline cellulosic material (126) thereon. The fibrous crystalline cellulosic material (126) is in a condition of having been gravure printed on the base web (140) as a fibrous crystalline cellulosic slurry that comprises water, crystalline cellulose, and chalk wherein the fibrous crystalline cellulosic slurry has a solids content of about 10% or less by weight of the fibrous crystalline cellulosic slurry.
