Description

Mundstückbelagspapier Tipping paper
Die Erfindung betrifft das Mundstückbelagspapier für einen Rauchartikel wie eine Filterzigarette oder einen mit einem Filter versehenen Zigarillo. The invention relates to the tipping paper for a smoking article such as a filter cigarette or a cigarillo provided with a filter.
Die Erfindung wird des Weiteren an Hand der Anwendung an Zigaretten beschrieben obwohl sie auch an Zigarillos, sofern diese mit einem Filter versehen sind, anwendbar ist. The invention is further described with reference to the cigarette application, although it is also applicable to cigarillos provided they are provided with a filter.
Wesentliche Teile einer üblichen Filterzigarette sind der Tabakstrang, das diesen einhüllende Zigarettenpapier, der Filter, das diesen unmittelbar einhüllende Filterhüllpapier und das Mundstückbelagspapier . Essential parts of a conventional filter cigarette are the tobacco rod, the wrapping this cigarette paper, the filter, this immediately enveloping filter wrapping paper and the mouthpiece covering paper.
Das Mundstückbelagspapier, oft auch als „Tippingpapier" oder kurz "Tipping" bezeichnet, ist jener Teil der Filterzigarette, welcher beim Rauchen der Filterzigarette durch die Lippen der die Zigarette rauchenden Person berührt wird. Es umhüllt den Filterteil und ragt üblicherweise in Längsrichtung der Filterzigarette auch geringfügig in den Längsbereich des Tabakstranges und umhüllt dort das Zigarettenpapier. Es ist mit dem Filterhüllpapier und dem Zigarettenpapier durch eine Klebung verbunden. Durch das Herstellen dieser Klebung werden in der Zigarettenmaschine Filterteil und Tabakstrangteil mechanisch verbunden. Das Mundstückbelagspapier ist zumeist tatsächlich ein Papier, es kann aber auch eine Folie (oftmals auch mit "Film" bezeichnet) sein oder auch ein Verbundmaterial aus mehreren Schichten verschiedener Materialien.  The tipping paper, often referred to as "tipping paper" or "tipping" for short, is that part of the filter cigarette which is touched by the lips of the person smoking the cigarette when the filter cigarette is smoked, enveloping the filter part and usually extending longitudinally of the filter cigarette It is adhesively bonded to the filter wrap paper and the cigarette paper, and by making this bond, the filter part and the tobacco rod part are mechanically connected in the cigarette machine.The tipping paper is, in fact, a paper but also a film (often also called "film") or even a composite material of several layers of different materials.
Üblicherweise weist das Mundstückbelagspapier eine Bedruckung auf. Beispielsweise kann diese Bedruckung an Kork erinnern.  Usually, the tipping paper has an imprint. For example, this print can be reminiscent of cork.
In der GB433228 A wird schon 1934 vorgeschlagen, das Zigarettenpapier von filterlosen Zigaretten zumindest an einem Ende, welches bestimmungsgemäß beim Rauchen mit den Lippen berührt werden soll, mit Nitrozelluloselack getränkt auszuführen. Vorteile sei- nen unter anderem, dass damit die Emission von Rauchinhaltsstoffen an die Lippen vermindert werde, dass das Zigarettenpapier bei Berührung mit den Lippen weniger nass werde und dass das Zigarettenpapier weniger an den Lippen klebe. In GB433228 A, it is proposed as early as 1934 that the cigarette paper of filterless cigarettes should be soaked with nitrocellulose lacquer, at least at one end, which is intended to be touched when smoking with the lips. Advantages Among other things, that it reduces the emission of smoke ingredients to the lips, that the cigarette paper gets less wet on contact with the lips and that the cigarette paper sticks less to the lips.
Die Schriften US 2755206 A, US 3916914 A, CN 2193654 Y und EP 1895863 Bl beschreiben Zigarettenfilter, welche im Filterkern Stoffe wie typischerweise Aromastoffe in flüssiger Form gespeichert haben, wobei diese Stoffe typischerweise in einer Kapsel aufbewahrt sind, welche durch eine äußere Druckkraft soweit aufgebrochen werden kann, dass der Stoff mit dem Rauchstrom aus dem Tabakteil der Zigarette in Kontakt kommen und seine Wirkung entfalten kann. Damit der flüssige, typischerweise ölige Stoff nicht das Mundstückbelagspapier, also die äußerte Umhüllungsschicht des Filters der fertigen Zigarette, durchtränkt und verfärbt, sind das Mundstückbelagspapier und der den flüssigen Stoff beinhaltende Filterkern durch eine kreiszylindermantelför- mige Zwischenschicht aus einem flüssigkeitsdichten Trennmaterial getrennt . The documents US 2755206 A, US 3916914 A, CN 2193654 Y and EP 1895863 Bl describe cigarette filters which have stored in the filter core substances such as typically flavorings in liquid form, these substances are typically stored in a capsule which has been broken by an external pressure force can be that the substance with the smoke flow from the tobacco part of the cigarette in contact and can develop its effect. So that the liquid, typically oily substance does not soak and discolour the mouthpiece covering paper, that is to say the outer coating layer of the filter of the finished cigarette, the mouthpiece covering paper and the filter core containing the liquid substance are separated by a circular-cylindrical jacket-like intermediate layer from a liquid-tight separating material.
Die GB 1422286 AI und die DE 2327822 AI beschreiben ein Mundstückbelagspapier, welches aus einem Kunststofffilm besteht und auf seiner Außenseite eine zusätzliche Bedruckung mit Lack aufweist. Diese zusätzliche Bedruckung kann in zwei Schichten aufgebracht sein.  GB 1422286 AI and DE 2327822 AI describe a mouthpiece covering paper, which consists of a plastic film and on its outer side has an additional printing with paint. This additional printing can be applied in two layers.
Die DE 630817 C beschreibt ein Mundstückbelagspapier welches außen eine Schicht aus Echtgold aufweist. Dazu wird am Mundstückbelagspapier eine erste Lackschicht aufgebracht, auf welcher die Goldschicht kathodisch aufgetragen wird. Über der Goldschicht wird eine weitere Lackschicht aufgebracht um Abrieb zu vermeiden .  DE 630817 C describes a mouthpiece covering paper which has a layer of real gold on the outside. For this purpose, a first lacquer layer is applied to the tipping paper on which the gold layer is applied cathodically. Over the gold layer, another paint layer is applied to avoid abrasion.
Die GB 269194 A beschreibt ein Mundstückbelagspapier auf welchem außen eine Schicht aus pulverisiertem Glimmer aufgebracht ist, welcher in Mischung mit einem Lack aufgebracht wird. Über dieser Glimmerschicht wird eine weitere Lackschicht aufgetragen. Die US 20080029111 AI beschreibt ein aus zwei Lagen gebildetes Mundstückbelagspapier, wobei die äußere Lage vom Raucher entfernt werden kann. Falls die innere Lage eine Beschichtung mit Empfindungsstoffen aufweist, dient die äußere Lage dazu, die Beschichtung der inneren Lage gegen Einflüsse von außen zu schützen . GB 269194 A describes a tipping paper on which is externally applied a layer of powdered mica which is applied in admixture with a lacquer. Over this mica layer, another paint layer is applied. US 20080029111 AI describes a tipping paper formed from two layers, wherein the outer layer can be removed by the smoker. If the inner layer has a coating with sensory substances, the outer layer serves to protect the coating of the inner layer against outside influences.
In der DE 1928432 U und in der DE 1532252 AI wird vorgeschlagen, den beim Rauchen mit den Lippen zu berührenden Längsbereich von Filterzigaretten mit einem desodorierenden Mittel oder Geschmacksmittel zu tränken um zu verhindern, dass durch im Rauch enthaltene Stoffe, geschmacklich unangenehme Stoffe auf den Lippen wirksam werden. Es wird auch vorgeschlagen, den mit einem derartigen Mittel versehenen Oberflächenbereich durch eine Bedruckung, farblich von angrenzenden Oberflächenbereichen unterscheidbar zu machen. In DE 1928432 U and in DE 1532252 AI it is proposed to impregnate the smoking during the smoking with the lips longitudinal portion of filter cigarettes with a deodorizing agent or flavoring to prevent that by substances contained in the smoke, unpleasant tastes on the lips be effective. It is also proposed to make the surface area provided with such an agent distinguishable by color from adjacent surface areas.
In der US 20030178039 AI wird ein Mundstückbelagspapier beschrieben, das zu 20-70 Gew.-% aus wasserdispergierbarem Zellulosematerial, zu 20-70 Gew.-% aus einem wasserlöslichem Filmbildner und zu 0-10 Gew.-% aus einem Feuchthaltemittel besteht. Dieses Mundstückbelagspapier wird außen bedruckt und mit einer Schicht Lip-Release-Coating überzogen. Unter Lip-Release-Coating versteht man eine Substanz, welche das Anhaften der Lippen am Mundstückbelagspapier verhindert und üblicherweise als Lack aufgebracht wird.  In US 20030178039 Al a tipping paper is described which consists of 20-70 wt .-% of water-dispersible cellulose material to 20-70 wt .-% of a water-soluble film-forming agent and 0-10 wt .-% of a humectant. This tipping paper is printed on the outside and coated with a layer of lip release coating. Lip-release coating is understood to mean a substance which prevents the lips from adhering to the tipping paper and is usually applied as a lacquer.
In der DE 2743986 AI wird vorgeschlagen, ein Mundstückbelagspapier, das durch geprägte Vertiefungen einen an Kork angepassten Oberflächencharakter aufweist, außen mit einer Lackschicht zu überziehen, um eine verbesserten Glanzeffekt zu erzielen. Dieser Effekt besteht darin, dass die Lackschicht in den geprägten und somit verdichteten Bereichen weniger in das Papier eindringt als in den übrigen Bereichen. So wirkt dieser glänzend in den Vertiefungen und matt im übrigen Bereich. Die WO 2009/027331 A2 zeigt ein Mundstückbelagspapier, welches außen eine Beschichtung mit kühlend wirkenden Substanzen aufweist. Die kühlend wirkende Substanz wird mit einem Trägerstoff bzw. Lösemittel (Trägerlack) aufgetragen. Dabei handelt es sich um Nitrozelluloselack, da dieser wenig beständig gegenüber Feuchtigkeit ist. So ist es möglich, die kühlend wirkende Substanz über die Lippen aufzunehmen, auch wenn die aufgetragene kühlend wirkende Beschichtung durch eine zusätzliche Beschichtung mit dem Trägerlack überdeckt ist. In einer Ausführungsvariante wird das Mundstückbelagspapier bereits vor dem Aufbringen der kühlend wirkenden Substanz mit dem Trägerlack versehen. So wird erreicht, dass während der Lagerung die Migration der kühlend wirkenden Substanz in den Filter der Zigarette vermindert wird. Nachteilig ist, dass für die Vorbehandlung des Mundstückbelagspapiers derselbe Lack verwendet wird, der auch als Lösemittel der kühlend wirkenden Substanz eingesetzt wird. Dadurch tritt, vor allem bei Vorliegen von Feuchtigkeit, eine Migration der kühlend wirkenden Substanz durch die Lackschicht auf. Diese Migration durch die Lackschicht ist gemäß der WO 2009/027331 A2 sogar erforderlich, um Migration der kühlend wirkenden Substanz nach außen, an die Lippen des Rauchers zu ermöglichen. In DE 2743986 Al it is proposed that a mouthpiece covering paper, which has a surface character adapted to cork by embossed depressions, be coated on the outside with a lacquer layer in order to achieve an improved gloss effect. This effect is that the lacquer layer penetrates less in the embossed and thus compacted areas in the paper than in the other areas. So it looks shiny in the depressions and dull in the rest of the area. WO 2009/027331 A2 shows a mouthpiece covering paper, which on the outside has a coating with cooling substances. The cooling substance is applied with a carrier or solvent (carrier lacquer). This is nitrocellulose lacquer because it is less resistant to moisture. Thus, it is possible to take the cooling substance over the lips, even if the applied cooling-acting coating is covered by an additional coating with the carrier lacquer. In one embodiment, the mouthpiece covering paper is provided with the carrier lacquer before the application of the cooling substance. This ensures that the migration of the cooling substance into the filter of the cigarette is reduced during storage. The disadvantage is that the same lacquer is used for the pretreatment of the mouthpiece covering paper, which is also used as a solvent of the cooling substance. As a result, especially in the presence of moisture, migration of the cooling substance through the lacquer layer occurs. This migration through the lacquer layer is even required, according to WO 2009/027331 A2, in order to allow migration of the cooling substance to the outside, to the lips of the smoker.
Hinsichtlich des Bedruckens von Mundstückbelagspapier werden Art des Druckmaterials, Druckverfahren und aufgetragener Menge von Druckmaterial so ausgewählt bzw. bemessen, dass die Bedruckung den Beanspruchungen bei der Herstellung der Zigaretten, bei Verpackung, Transport und Lagerung der Zigaretten und natürlich beim Rauchen der Zigaretten sicher vollständig standhält und somit durch die Bedruckung keinerlei störende Nebeneffekte wie Abfärben etc. verursacht werden. Gemäß den nach dem Stand der Technik offenbarten Verfahren wird das dadurch erreicht, dass an der Außenseite des Mundstückbelagspapiers eine Bedruckung aufgebracht wird, die mit einer darüber aufgebrachten Versiegelungsschicht geschützt wird. Während die Bedruckung dadurch bereits gut gegen Einflüsse von außen schützbar ist, gibt es noch keine zufriedenstellende, einfache Lösung die Bedruckung durch Einflüsse aus dem Inneren der Zigarette zu schützen. With regard to the printing of tipping paper, the type of printing material, printing method and amount of printing material applied are selected so that the printing completely reliably withstands the stresses in the production of the cigarettes, in the packaging, transport and storage of the cigarettes and, of course, in the smoking of the cigarettes and thus no disturbing side effects such as discoloration etc. are caused by the printing. According to the method disclosed in the prior art, this is accomplished by applying a print to the outside of the tipping paper which is protected with a sealing layer applied over it. While printing thereby already is well protected against external influences, there is still no satisfactory, simple solution to protect the print by the influence of the inside of the cigarette.
Die der Erfindung zu Grunde liegende Aufgabenstellung zielt darauf ab, die Auswahlmöglichkeiten für Bedruckungen für das Mundstückbelagspapier einer Zigarette hinsichtlich Art, Menge und Kombinierbarkeit von Bedruckungsmaterialien zu erweitern. Dabei soll vorrangig die Migration von Substanzen aus dem Inneren der Zigarette in die Bedruckung verhindert werden, wodurch zusätzlich erreicht wird, dass auch die Migration von Inhaltsstoffen der Bedruckung in das Innere der Zigarette verhindert wird.  The object of the invention is based on expanding the options for printing on the mouthpiece covering paper of a cigarette with regard to the type, quantity and combinability of printing materials. The primary aim is to prevent the migration of substances from the interior of the cigarette into the printing, which additionally ensures that the migration of ingredients of the printing into the interior of the cigarette is also prevented.
Unter Bedruckung wird in der gegenständlichen Schrift das Aufbringen von Lack verstanden, welcher eine optische oder hapti- sche Funktion haben und/oder Empfindungsstoffe beinhalten kann. Unter dem Begriff „Empfindungsstoff" werden Substanzen mit sensorische Funktion, wie beispielsweise Aromastoffe oder Geschmacksstoffe verstanden. Des Weiteren werden in dieser Schrift auch Substanzen, welche dazu in der Lage sind Geruchsstoffe zu binden, oder abzubauen, sowie Substanzen mit bleichender Wirkung unter dem Begriff Empfindungsstoffe zusammengefasst .  Printing in the present document is understood to mean the application of lacquer, which may have an optical or haptic function and / or contain sensory substances. The term "sensory substance" is understood as meaning substances with sensory function, such as, for example, flavorings or flavoring substances.Furthermore, in this document, substances which are capable of binding or degrading odors, and substances having a bleaching effect are also referred to as sensory substances summarized .
Zum Lösen der Aufgabe wird vorgeschlagen, das Mundstückbelagspapier nach dem Bedrucken mit einer versiegelnden Lackschicht an seiner Innenseite zu versehen, welche Migration verhindert. To solve the problem it is proposed to provide the mouthpiece covering paper after printing with a sealing lacquer layer on its inner side, which prevents migration.
Ein Lack in diesem Sinne ist ein flüssiger oder auch pulverför- miger Beschichtungsstoff , der dünn auf Gegenstände aufgetragen wird und durch chemische oder physikalische Vorgänge einen durchgehenden festen Film, die sogenannte Lackschicht, bildet.A paint in this sense is a liquid or pulverulent coating material, which is applied thinly to objects and forms by chemical or physical processes a continuous solid film, the so-called paint layer.
Bevorzugt ist die versiegelnde Lackschicht durchsichtig. Weiter bevorzugt ist sie farblos. Preferably, the sealing lacquer layer is transparent. More preferably, it is colorless.
Überraschenderweise wurde festgestellt, dass als Lack, mit welchem die versiegelnde Lackschicht gebildet werden kann, der nach dem Stand der Technik viel genutzte Nitrozelluloselack nur be- grenzt geeignet ist, da Nitrozelluloselack nur begrenzt feuchtigkeitsbeständig ist. Bei Kontakt mit Feuchtigkeit wird daher die unter dem Lack befindliche Bedruckung nur eine gewisse Zeit geschützt, welche von der Schichtdicke des Lacks abhängig ist. Zudem werden die im Lack gebundenen Substanzen frei, was in der zitierten WO 2009/027331 A2 genutzt wird, um die Migration der kühlend wirkende Substanz an die Lippe des Rauchers zu ermöglichen . It has surprisingly been found that, as lacquer with which the sealing lacquer layer can be formed, the state-of-the-art nitrocellulose lacquer is only used border is suitable because nitrocellulose lacquer is only limited moisture resistance. Upon contact with moisture, therefore, the printing located under the paint is only protected for a certain time, which depends on the layer thickness of the paint. In addition, the substances bound in the paint are released, which is used in the cited WO 2009/027331 A2, in order to allow the migration of the cooling substance to the lip of the smoker.
Um die Migration von Substanzen in die Bedruckung hinein und aus der Bedruckung heraus, selbst bei Vorliegen von Feuchtigkeit zu verhindern, wird vorgeschlagen einen feuchtigkeitsbeständigen Lack wie Schellack, Ethylcelluloselack oder Polyethylenwachs zu verwenden .  In order to prevent the migration of substances into and out of the print, even in the presence of moisture, it is proposed to use a moisture resistant varnish such as shellac, ethylcellulose varnish or polyethylene wax.
Nach dem Bedrucken des Mundstückbelagspapiers mit Lack, welcher eine optische und/oder eine haptische Funktion haben, sowie Empfindungsstoffe beinhalten kann, kann die erfindungsgemäß vorgesehene zusätzliche versiegelnde, feuchtigkeitsbeständige Lackschicht entweder durch einseitiges Auftragen des versiegelnden Lackes an der Innenseite des Mundstückbelagspapiers oder durch beidseitiges Imprägnieren des Mundstückbelagspapiers mit versiegelndem Lack erfolgen. Bei der zweiten Methode wird die Bedruckung auch gegen Einflüsse von außen, insbesondere gegen Feuchtigkeit geschützt. Für die außen aufgebrachte Versiegelungsschicht kann auch ein anderer Lack als für die innenliegende Schicht verwendet werden. Beispielsweise wenn Substanzen aus der Bedruckung an die Lippen gelangen sollen, kann ein wasserlöslicher Lack, beziehungsweise ein wenig feuchtigkeitsbeständiger Lack wie Nitrozelluloselack verwendet werden. After printing the tipping paper with lacquer, which have a visual and / or haptic function, as well as sensory substances, the inventively provided additional sealing, moisture-resistant lacquer layer can either by one-sided application of the sealing lacquer on the inside of the tipping paper or by double-sided impregnation of the Tipping paper with sealing lacquer done. In the second method, the printing is also protected against external influences, in particular against moisture. For the externally applied sealing layer, a different coating than for the inner layer can be used. For example, if substances from the printing should reach the lips, a water-soluble paint, or a little moisture-resistant paint such as nitrocellulose paint can be used.
Besonders vorteilhaft ist es, die Versiegelungsschicht an jener Seite des Mundstückbelagspapieres aufzutragen, welche an der fertigen Zigarette die Innenseite des Mundstückbelagspapiers bildet, wenn an der Innenseite des Mundstückbelagspapiers zuerst ein Lack für eine andere Funktion aufgetragen wurde. Beispielsweise kann dieser zuerst aufgetragene Lack ein Lack sein, durch den die Opazität des Mundstückbelagspapiers gezielt eingestellt wird. Besonders vorteilhaft ist die innenseitige Bedruckung und Versiegelung auch bei der Verwendung von durchsichtigem bzw. durchscheinendem Mundstückbelagspapier. Ein solches durchsichtiges bzw. durchscheinendes Mundstückbelagspapier liegt beispielsweise vor, wenn es aus einem sehr dünnen Papier, oder aus einer Folie wie Zellophan besteht. It is particularly advantageous to apply the sealing layer to that side of the tipping paper which forms on the finished cigarette the inside of the tipping paper when on the inside of the tipping paper first a paint was applied for a different function. For example, this first applied paint can be a paint, through which the opacity of the mouthpiece covering paper is adjusted specifically. Particularly advantageous is the inside printing and sealing even when using transparent or translucent mouthpiece covering paper. Such a translucent tipping paper is, for example, if it consists of a very thin paper, or of a film such as cellophane.
Durch das innenseitige Bedrucken ist die Bedruckung nach dem Zusammenstellen der Zigarette nach außen hin durch das Mundstückbelagspapier selbst geschützt. Nach innen ist die Bedruckung durch die Versiegelungsschicht geschützt, was bei der Verleimung des Mundstückbelagspapiers mit der darunterliegenden Schicht der Zigarette besonders vorteilhaft ist, da so die Bedruckung vor dem Leim, bzw. der im Leim enthaltenen Feuchtigkeit geschützt ist .  Due to the inside printing, the printing is protected after compiling the cigarette to the outside through the mouthpiece covering paper itself. Inside, the printing is protected by the sealing layer, which is particularly advantageous in the glueing of the mouthpiece covering paper with the underlying layer of the cigarette, as this protects the printing from the glue or the moisture contained in the glue.
Dieser Schutz vor der Feuchtigkeit, welche im Zuge der Verleimung zwangsläufig auftritt, ist auch vorteilhaft, wenn in der Bedruckung wasserlösliche Substanzen, wie Empfindungsstoffe vorhanden sind, da diese bei der Verleimung dazu neigen in tiefere Schichten der Zigarette zu migrieren.  This protection against moisture, which inevitably occurs in the course of the gluing, is also advantageous if water-soluble substances, such as sensory substances, are present in the printing, since these tend to migrate into deeper layers of the cigarette during the gluing.
Bei den meisten Anwendungen werden bei geringem Aufwand sehr gute Ergebnisse erzielt, indem der versiegelnde Lack zwar nur einseitig aufgetragen wird, dafür aber mehrmals in zeitlich hintereinander stattfindenden Auftragsvorgängen. In most applications, very good results are achieved with little effort by the sealing varnish is applied only on one side, but several times in successive order jobs.
Für das Auftragen der versiegelnden Lackschicht können die für das Imprägnieren und/oder Bedrucken von Mundstückbelagspapiers üblichen Verfahren angewendet werden. For the application of the sealing varnish layer, the usual methods for impregnating and / or printing mouthpiece covering paper can be used.
Die erforderliche Menge von versiegelndem Lack pro Papierfläche hängt von der Porigkeit des verwendeten Mundstückbelagspapiers und gegebenenfalls von der Art und der Menge des zuvor auf der- selben Seite aufgebrachten Lacks der Bedruckung ab. Sie ist im Rahmen des fachmännischen Handelns gut durch Näherungsüberlegungen und/oder durch Versuch zu ermitteln. The required amount of sealing varnish per paper surface depends on the porosity of the tipping paper used and, if applicable, on the type and quantity of the previously used same side applied lacquer of the printing. It is well within the framework of expert action to determine by approximate considerations and / or by experiment.
In einer vorteilhaften Ausführungsform ist das Mundstückbelagspapier vorzugsweise außen nicht vollflächig mit einer versiegelnden Lackschicht versehen, sondern vor allem an dem vom Tabakstrang der fertigen Zigarette abgewandten Endbereich, welcher der ist, welcher beim Rauchen der Zigarette mit den Lippen berührt wird. In an advantageous embodiment, the mouthpiece covering paper is preferably not provided on the outside with a sealing varnish layer on the entire surface, but above all on the end region facing away from the tobacco rod of the finished cigarette, which is the one which is touched when smoking the cigarette with the lips.
Indem der tabakstrangnahe Längsbereich des Mundstückbelagspapiers, welcher ja ohnedies nicht mit den Lippen berührt wird, nicht mit einer versiegelnden Lackschicht versehen ist (bzw. nicht mit einer so stark versiegelnden Lackschicht versehen ist) kann dort die Luftdurchlässigkeit des Mundstückbelagspapiers höher belassen sein, wie es in diesem Bereich für das Einstellen der Rauchwerte durch Frischluftbeimischung zum Rauchstrom vorteilhaft ist .  By not having a sealing varnish layer (or not provided with such a highly varnish varnish layer) near the tobacco rod-like longitudinal area of the tipping paper, which in any case is not touched with the lips, the air permeability of the tipping paper can be left higher this range is advantageous for adjusting the smoke values by adding fresh air to the smoke stream.
Durch die erfindungsgemäße Ausführung von Mundstückbelagspapieren werden auch die Anwendungsmöglichkeiten von Strukturlacken erweitert. Ein Strukturlack im Sinne dieser Beschreibung ist ein Lack, mit welchem sich auf einer Oberfläche ein Raster einer fühlbar erhabenen Struktur drucken lässt. The inventive design of mouthpiece covering papers also extends the application possibilities of structured coatings. A textured paint in the sense of this description is a paint with which can be printed on a surface, a grid of a tangibly raised structure.
Durch die erfindungsgemäße Ausführung von Mundstückbelagspapieren wird nicht nur Migration von Substanzen aus einer Lackschicht des Mundstückbelagspapiers verhindert. Es wird damit auch vermindert oder ganz verhindert, dass unerwünschte Substanzen aus anderen Teilen der Zigarette als der Lackschicht des Mundstückbelagspapiers an jene Oberfläche des Mundstückbelagspapiers migrieren, welche durch die Lippen der die Zigarette rauchenden Person berührt wird. Gegenüber dem Stand der Technik wird erreicht, dass die Bedruckung besser gegen Einflüsse aus dem Inneren der Zigarette geschützt ist und dieser Schutz zudem beim Vorliegen von Feuchtigkeit länger aufrecht bleibt. So wird auch die Migration von Substanzen bei Auftreten von Feuchtigkeit, wie es zumindest während des Verleimens und des Rauchens der Fall ist, gegenüber dem Stand der Technik noch zuverlässiger reduz iert . The inventive embodiment of mouthpiece covering papers not only prevents migration of substances from a lacquer layer of the mouthpiece covering paper. It also reduces or completely prevents unwanted substances from migrating from parts of the cigarette other than the lacquer layer of the tipping paper to that surface of the tipping paper which is contacted by the lips of the person smoking the cigarette. Compared to the prior art it is achieved that the printing is better protected against influences from the inside of the cigarette and this protection also remains longer in the presence of moisture. Thus, the migration of substances in the presence of moisture, as it is the case at least during the gluing and smoking, compared to the prior art even more reliably reduced iert.
