Definitions

  • a cigarette paper comprising at least one coated surface area and at least one non-coated surface area, wherein the cigarette paper is combustible and provides a mean volumetric flow rate of at least 40 cm 3 min ⁇ 1 air passing through a sample of 1 cm 2 of this cigarette paper at an applied pressure difference of 1 kPa, wherein the at least one coated surface area of the cigarette paper provides a glossiness of at least 4 GU according to DIN EN ISO 2813:2015, the at least one non-coated surface area provides a glossiness of less than 4 GU according to DIN EN ISO 2813:2015 and the difference of glossiness between the at least one coated surface area and the at least one non-coated surface area is more than 2 GU according to DIN EN ISO 2813:2015.
  • the percentage of the coated surface area is less than 80% of the total surface area of the cigarette paper, preferably less than 50%, more preferably in the range between 20% and 50%. Coatings of this dimension are preferred since these percentages allow for writings and/or illustrations on the cigarette paper. Furthermore, the required permeability of the cigarette paper is maintained. Higher percentages of the coated area result at least in some cases in reduced permeability of the cigarette paper, which could result in unwanted ignition of the cigarette.
  • the method comprises the step of selecting a suitable polymer.
  • the polymer is preferably selected from a group comprising EVA, PVA, any other copolymer of ethylene, any other copolymer of propylene, PE, and any other film forming polymer. These polymers have been found to be especially suitable for printing processes, especially for flexography.
  • FIG. 1 a an image of a tobacco stick, surrounded by a cigarette paper with coated and non-coated surface areas according to the invention
  • FIG. 2 b This embodiment is further illustrated by the schematic illustration of FIG. 2 b .
  • two stripes of coating intersect each other and form a checkered pattern on the cigarette paper 10 and/or the tobacco stick 1 .
