Abstract
A cigarette paper is disclosed that has at least one treated area to which a composition that contains filler particles or a mixture of filler particles is applied. The diffusion capacity thereby in the at least one treated area is less than in an untreated area of the cigarette paper, wherein at least 20% by weight, preferably at least 50% by weight and particularly preferably at least 70% by weight of the filler particles in the treated area are formed by a filler with a flaked shape or a filler with a cubic shape. Additionally or alternatively, a filler with a scalenohedral or rhombohedral crystal structure can be used, as long as the particle size distribution is selected appropriately.
