Abstract
A mouthpiece lining paper for a smoking article, which mouthpiece lining paper forms the outermost layer of the casing of the filter.

Between the raised areas, surface regions of the mouthpiece lining paper are provided, above which the raised areas protrude by at least 5 μm in the direction perpendicular to the plane of the mouthpiece lining paper.
Claims24
A mouthpiece lining paper for a cigarette, which forms the outermost layer of the casing of the filter, comprising
- a structure of locally limited elevations made of hardened varnish, said elevations project by at least 5 μm in the direction normal to a plane of surface areas of the mouthpiece lining paper that are located between said elevations;
- wherein the elevations are arranged on the outer side of the mouthpiece lining paper, and said surface areas that are located between said elevations are provided with substances, said elevations project further from the plane of the mouthpiece lining paper than said substances.
A mouthpiece lining paper for a cigarette, which forms the outermost layer of the casing of the filter, comprising
- a structure of locally limited elevations made of hardened varnish, said elevations project by at least 5 μm in the direction normal to a plane of surface areas of the mouthpiece lining paper that are located between said elevations;
- wherein the elevations consist of a hardened varnish which, with respect to metal and/or ceramic, has a lower coefficient of friction than said surface areas that are located between said elevations or substances that are applied to said surface areas.
A method for the production of a mouthpiece lining paper for a cigarette which forms the outermost layer of the casing of the filter, wherein
- varnish is applied to the mouthpiece lining paper in a structure of locally limited elevations and surface areas of the mouthpiece lining paper that are located between said elevations are applied with at least one other substance,
- wherein the mouthpiece lining paper provided with said elevations is treated with a gaseous, vapor-like, aerosol-like or powder-like active material or an active material from the combination thereof, in that it is stored and/or forcibly flooded as a roll in an environment which is enriched with the gaseous, vapor-like, aerosol-like or powder-like active material or an active material from the combinations thereof to apply said active material to the surface areas of the mouthpiece lining paper that are located between said elevations.
A mouthpiece lining paper for a cigarette, which forms the outermost layer of the casing of the filter, comprising,
- a structure of locally limited elevations made of hardened varnish, said elevations project by at least 5 μm in the direction normal to the plane of surface areas of the mouthpiece lining paper that are located between said elevations, wherein said mouthpiece lining paper is a film or foil material.
