Abstract
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.
Claims16
A smoking article wrapper, such as a cigarette paper, comprising 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 cm3min−1 air passing through a sample of 1 cm2 of the smoking article wrapper at an applied pressure difference of 1 kPa,
- the at least one coated surface area of the smoking article wrapper 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 a 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.
A method for producing a smoking article comprising a smoking article wrapper having a glossiness of at least 4 GU according to DIN EN ISO 2813:2015 in first parts of a surface of the smoking article wrapper and a glossiness of less than 4 GU according to DIN EN ISO 2813:2015 in other second parts of the surface, wherein a difference of glossiness between the first and second parts is more than 2 GU according to DIN EN ISO 2813:2015, the method comprising:
- printing a polymer on areas of the smoking article wrapper by flexography.
