Smoking Article Wrapper

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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application is a national phase entry under 35 U.S.C. § 371 of International Application No. PCT / EP2020 / 073315, filed Aug. 20, 2020, published in English, which claims priority to European Application No. 19193384.5 filed Aug. 23, 2019, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a smoking article wrapper and a method for producing such a smoking article wrapper according to the preamble of present claims 1 and 13. Furthermore, the present invention relates to a smoking article comprising a smoking article wrapper according to the preamble of present claim 1.[0003]Smoking articles such as cigarettes are consumer goods produced in large quantities. They usually comprise a tobacco rod formed by wrapping tobacco cut filler with a paper based wrapper in a longitudinally extending substantially cylindrical rod. Beyond their primary tobacco wrapping ...

AI Technical Summary

Benefits of technology

The patent describes a method for making cigarettes with a visual appearance that is enhanced compared to regular cigarettes. This is achieved by adding a coating of polymer to the cigarette paper. The method involves printing the polymer onto the paper as an emulsion, suspension, or molten form and then drying it. The resulting coating is relatively low in glossiness, but if there is a significant difference in glossiness between the coated and uncoated areas, it can be easily recognized by the consumer. The methods described in the patent make it easier to produce cigarettes with a visually appealing appearance.

Problems solved by technology

A higher glossiness usually requires higher amounts of coating material, which limits the permeability of the cigarette paper and / or increases costs.
