Abstract
A smoking article wrapper has discrete areas of reduced permeability for improving ignition proclivity characteristics of a smoking article. The reduced permeability areas define a gradually decreasing permeability profile in a burning direction of the smoking article such that permeability reduction in the reduced permeability areas increases from a minimum reduction to a maximum permeability reduction in the burning direction of the smoking article.
