    摘要: A cigarette paper is disclosed that contains at least one burn additive the concentration c(x) of which varies along a direction x of the cigarette paper. For the position-dependent concentration c(x) over an interval of length L, for x over the interval [0,L], ƒ(x)−Δc≤c(x)≤ƒ(x)+Δc. In this regard, 3 cm≤L≤11 cm, ƒ(x) is monotonic over the interval [0,L], but not a constant function over the entire interval, and Δc≤1% by weight, preferably ≤0.7% by weight and particularly preferably ≤0.5% by weight, and especially preferably ≤0.3% by weight and particularly preferably ≤0.15% by weight and Δc>0% by weight, each with respect to the mass of the cigarette paper.

    摘要: The invention relates to cigarette paper which contains a water-soluble salt, preferably sodium bicarbonate, potassium bicarbonate or ammonium carbonate, as a result of which a high diffusion capacity during thermal decomposition, and thus a reduction in harmful carbon monoxide in the cigarette smoke, is achieved. The invention relates in particular to cigarette paper comprising at least one water-soluble salt which has lost more than 15% of its initial mass after heating to 230° C. The invention further relates to a cigarette produced from the cigarette paper, to a method for producing the cigarette paper and to the use of the water-soluble salt.

    摘要: A wrapping material for a smoking article is disclosed, which has a laminar shape that extends further in two mutually orthogonal spatial directions X and Y than in a third spatial direction Z orthogonal to the spatial directions X and Y. The wrapping material has, at least in part of its area, a first and a second diffusion capacity D1 and D2 for a diffusion of CO2 through the wrapping material in the +Z-direction and the −Z-direction, respectively, wherein for the first and second diffusion capacity D1 and D2, each an average of 10 values, one or both of the following relationships (i) and (ii) hold: |D1−D2|≥0.03 cm/s  (i) at a probability of error of 1% 2 ⁢  D 1 - D 2  D 1 + D 2 ≥ 0.030 .
