Laser-Etched Aerosol-Generating Article Wrapper, Aerosol-Generating Articles Comprising Such, and Their Method of Manufacture

Abstract

An aerosol-generating article wrapper includes at least one layer of cellulosic material having a thickness extending from a first surface to a second surface opposite the first one of at least 35 micrometers and a tensile strength of at least 25 N/15 mm. The wrapper material includes at least part of an indicium etched in the at least one layer over a determined depth less than its thickness from one of the first or second surfaces. A method of manufacturing such wrapper includes a step of etching at least part of an indicium into the wrapper by evaporating wrapper material with a laser beam according to indicium vector lines over a determined depth less than the thickness of the cellulosic material layer. An aerosol-generating article includes such wrapper around at least a portion thereof, wherein the indicium in the wrapper is arranged at an outer facing surface of the article.
