A cigarette wrapper 123 includes transversely extending banded regions 126 applied by a printing technique, such as gravure printing. The banded regions are applied in a single application of an aqueous starch solution also containing an anti-wrinkling agent such as propylene glycol, and calcium carbonate. The pattern of banded regions may be bands or stripes and the like which lie along and/or around a tobacco rod in a cigarette including the wrapper. The banded regions may be solid or contain any number of cross-web and/or longitudinal discontinuities. The pattern may be configured so that when a smoking article including the wrapper is placed on a substrate, at least two longitudinal locations along the length of the tobacco rod have film-forming compound located only on sides of the smoking article not in contact with the substrate.; The invention includes a tobacco rod including the wrapper, a smoking article including the tobacco rod and processes for making the wrapper, as well as a method of abating the tendency of wrapper with an aqueous starch-based printed pattern to wrinkle during its manufacture. |
