摘要： A wrapper 10 for an aerosol-generating article includes at least one coated surface area and at least one non-coated surface area, wherein the coating of the at least one coated surface area of the wrapper is heat-sensitive, wherein the coating indicates heat application by a permanent color change. An aerosol generating article includes such a wrapper. A method for producing an aerosol generating article includes such a wrapper by printing a polymer on parts of the wrapper by flexography.

摘要： A smoking article wrapper includes a non-perforated air permeable base paper having a naturally high porosity of 40-80 cm3/min air passing through a sample of 1 cm2 of this base paper at an applied pressure difference of 1 kPa, wherein the smoking article wrapper has at least one embossed surface area and at least one non-embossed surface area. The air permeability of the smoking article wrapper is such that it provides a mean volumetric flow rate of ≥40 cm3/min air passing through a sample of 1 cm2 of this smoking article wrapper at an applied pressure difference of 1 kPa. The embossed area includes an embossing having a depth of ≥16 μm. A smoking article including the smoking article wrapper and respective methods to produce such a smoking article wrapper and a smoking article are also provided.

摘要： A smoking article wrapper includes at least one coated surface area and at least one non-coated surface area, wherein the smoking article wrapper is combustible and provides a mean volumetric flow rate of at least 40 CU, wherein the at least one coated surface area provides a glossiness of at least 4 GU, the at least one non-coated surface area provides a glossiness of less than 4 GU 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. A smoking article includes such a smoking article wrapper. A method for producing a smoking article includes such a smoking article wrapper by printing a polymer on parts of the smoking article wrapper by flexography.
