Smoking articles include a colour shifting marking. The marking may be provided on a wrapper, such as a plug wrap, a smokable material wrap, or a tipping paper wrap. The marking may be produced by a gonichromatic pigment to provide a smooth transition between colours as viewing angles change. The marking may allow a consumer to identify the smoking article as genuine, as opposed to counterfeit.

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.

The invention relates to a tobacco related product comprising standard tobacco related fibers, elements and/or particles and further additional tobacco related elements configured to detectably distinguish from standard tobacco related fibers, elements and/or particles and methods of manufacturing and authenticating such a tobacco related product.

A label applying apparatus and a related method are provided. The label applying apparatus may include a label applicator and a receptacle. The label applicator may include a displaceable piston with an applicator surface configured to receive a label. The receptacle may include walls that define an interior compartment. Further the receptacle may include a pivotable cover member that pivots about a hinge between a closed position that covers an upper opening of the receptacle and an open position in which articles of material may be inserted into the interior compartment. The distal end of an upper portion of the pivotable cover member may engage the articles such that the articles are retained in a position whereby the displaceable piston extends into the interior compartment and applies a label to a label application surface of the most proximate one of the articles to the applicator surface of the displaceable piston.

The present invention relates to an aerosol-generating article, adapted to be electrically heated by an aerosol-generating device. The aerosol-generating article comprises an aerosol-generating substrate, an optical information storage element storing information in a grid pattern with a plurality of segments comprising at least one alterable segment. The at least one alterable segment comprises a first layer and a second layer, wherein at least one optical property of at least one layer is adapted to be altered. The invention further relates to a method for manufacturing an information storage element, an aerosol-generating system comprising an aerosol-generating article and an aerosol-generating device and the use of a multi-layered information storage element on an aerosol-generating article to provide alterable supplemental information about the aerosol-generating article.
