A wrapper 123 for cigarette manufacture includes one or more transversely extending band regions 126 applied by a printing technique, such as gravure printing. The band regions comprise starch, an anti-wrinkling agent such as 1,2 propylene glycol or glycerin, and optionally calcium carbonate. Any suitable printing technique can be used to apply the aqueous solution to the banded regions. The pattern of banded regions may be bands, stripes, two-dimensional arrays, undulated regions, and the like along and/or around the tobacco rod. The pattern can be applied in one or more layers. The pattern may be configured so that when a smoking article 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 also encompasses a smoking article 120 including such a wrapper around a column of tobacco to form a tobacco rod 122. A method of providing a smoking article having an ignition propensity not greater than 25% is also disclosed.
