Abstract (en)
[origin: WO2019042639A1] The invention relates to a method for marking a wrapping paper for smoking articles, comprising the following steps: (A) providing a wrapping paper for smoking articles, the wrapping paper comprising pulp fibers, and (B) producing markings on the wrapping paper by means of at least one of the following steps: (B.1) removing material from the wrapping paper, (B.2) mechanically changing the wrapping paper, (B.3) treating the surface of the wrapping paper with laser radiation having an energy density y in J-m-2, to which the following applies: y = k - x. x is the enthalpy of combustion per volume of the wrapping paper in J-m-2μm-1, and k is at least -8 μm, preferably at least -7 μm and especially preferably at least -6. μm, and at most -1 μm, preferably at most -2 μm and especially preferably at most -2.5 μm. Either repeating structures are produced on the wrapping paper in a step (C) such that each structure is at a fixed distance in the machine direction relative to at least one marking, or in step (A) a wrapping paper is provided which has repeating structures in the machine direction, and the markings are produced on the wrapping paper in step (B) in such a way that each marking is at a fixed distance in the machine direction relative to at least one structure.
