Definitions
- the invention relates to a cigarette mouthpiece covering paper, consisting of a base paper of lo - 4o g / m2 weight and a printed printing ink.
- Such cigarette tip papers have been known for decades.
- colored papers were used as the base paper, more recently white papers are used, which are printed twice with printing ink.
- These are papers that are used as a filter wrapper, as a mouthpiece or as a filter or mouthpiece coating.
- the printed printing ink has organic solvents, which are removed from the printed cigarette mouthpiece covering paper by evaporation after drying in drying systems and are passed into the free environment by suction systems.
- the environmental protection authorities have also requested recovery systems for the solvent so that the smell of the solvent does not affect local residents who are close to production facilities.
- Such systems are expensive and expensive to operate because they consume significant amounts of energy.
- the base papers used must have a number of technical properties, such as a special tear strength, for example, in order to be able to fast forward of printing and quick drying following the printing, but also to be able to be processed quickly in the cigarette machines. For this reason, the industry uses a base paper which has a water absorption capacity of about 17 g / m2 in 60 seconds, measured in the Cobb test.
- the invention consists in that a base paper is used as paper which in the Cobb test has a water absorption capacity of 6-12 g / m 2 in 60 seconds, that at least 60% of water is used as solvent in the printing ink and that as a binder for the Pigments shellac is used.
- Such a cigarette tip paper has the advantage that the print gives an improved picture, which may be due to the fact that when using shellac on the surface, pigments are exposed which were completely enclosed by the binder in the previously used binders the printing ink due to moisture or water on the lips of the consumer is not possible because the shellac after it has solidified in the drying process after the printing process can no longer be solved by simple water. This is also the reason why the pigment exposed on its surface facing away from the paper cannot be detached from the paper or the binder between the pigment and the paper.
- drying water as a solvent does not pose any environmental problems. The ink can be extinguished with water in the event of fire, if it catches fire at all. That is also a Advantage during transport and storage because no special precautionary measures against fire have to be taken.
- a cigarette tip paper is produced with a light brown base paper, which has 3o g / m2 weight and a water absorption capacity of 9 g / m2 in 60 seconds in the Cobb test.
- This base paper is printed with a printing ink containing 9o% water and 1o% ethyl alcohol as a solvent.
- Shellac is used as a binding agent used in the following composition: 40% solvent 15% shellac 35% pigments, which are composed of mixtures of iron oxide and titanium oxide.
- This ink was applied to the base paper on a conventional printing machine, as has been used for years in the manufacture of cigarette tip paper. With the same drying times, there were improved images compared to printing inks with organic solvents.

Abstract
Description
Die Erfindung betrifft ein Zigarettenmundstücksbelagpapier, bestehend aus einem Basispapier von lo - 4o g/m² Gewicht und einer aufgedruckten Druckfarbe.The invention relates to a cigarette mouthpiece covering paper, consisting of a base paper of lo - 4o g / m² weight and a printed printing ink.
Derartige Zigarettenmundstücksbelagpapiere sind seit Jahrzehnten bekannt. Als Basispapier wurden früher eingefärbte Papiere verwandt, in neuerer Zeit werden weiße Papiere verwandt, die zweimal mit Druckfarbe bedruckt sind. Es handelt sich hier um solche Papiere, die als Filterumhüllung, als Mundstück oder als Filter bzw. Mundstücksbelag verwendet werden. Die aufgedruckte Druckfarbe weist organische Lösungsmittel auf, die nach dem Druckvorgang in Trockenanlagen von dem bedruckten Zigarettenmundstücksbelagpapier durch Verdunsten entfernt werden und durch Absauganlagen in die freie Umgebung geleitet werden. In neuerer Zeit werden von den auf Umweltschutz bedachten Behörden auch Rückgewinnungsanlagen für das Lösungsmittel gefordert, damit der Lösungsmittelgeruch nicht in der Nähe von Fabrikationsstätten wohende Anwohner beeinträchtigt. Derartige Anlagen sind kostspielig und im Betrieb teuer, weil sie erhebliche Energie verbrauchen. Die verwendeten Basispapiere müssen eine Reihe von technischen Eigenschaften, wie eine besondere Reißfestigkeit z.B., haben, um einerseits einen schnellen Vor gang des Bedruckens und eines schnellen Trocknens im Anschluß an das Bedrucken zu haben, aber auch um schnell in den Zigarettenmaschinen verarbeitet werden zu können. Aus diesem Grunde benutzt die Industrie ein Basispapier, welches eine Wasseraufnahmefähigkeit von etwa 17 g/m² in 60 Sekunden aufweist, gemessen im Cobb-Test.Such cigarette tip papers have been known for decades. In the past, colored papers were used as the base paper, more recently white papers are used, which are printed twice with printing ink. These are papers that are used as a filter wrapper, as a mouthpiece or as a filter or mouthpiece coating. The printed printing ink has organic solvents, which are removed from the printed cigarette mouthpiece covering paper by evaporation after drying in drying systems and are passed into the free environment by suction systems. In recent times, the environmental protection authorities have also requested recovery systems for the solvent so that the smell of the solvent does not affect local residents who are close to production facilities. Such systems are expensive and expensive to operate because they consume significant amounts of energy. The base papers used must have a number of technical properties, such as a special tear strength, for example, in order to be able to fast forward of printing and quick drying following the printing, but also to be able to be processed quickly in the cigarette machines. For this reason, the industry uses a base paper which has a water absorption capacity of about 17 g / m² in 60 seconds, measured in the Cobb test.
Versuche, als Lösungsmittel in der Druckfarbe Wasser zu verwenden, was die Druckfarbe schwerer entflammbar und bei Brand leichter löschbar machen würde, sind bisher gescheitert, weil die als Basispapier verwendbaren Papiere sich aus mehrerenGründen nicht für eine Bedruckung mit Farben eignen, die Wasser alsLösungsmittel enthalten: In Versuchen kräuselten sich die Basispapier nach dem Bedruckungsvorgang und beim Aufwickeln auf die Bobine, das Druckbild war nicht einwandfrei, sondern infolge einer zu hohen Wasseraufnahmefähigkeit des Basispapieres verwaschen, das gekräuselte Papier ließ sich auf den Zigarettenmaschinen nicht verarbeiten, weil seine Reißfestigkeit abgenommen hatte, auch der glatte Einlauf des Papieres in die Maschine war nicht mehr gewährleistet und es gab daher ständig Produktionsunterbrechungen durch ein Abreißen des von der Bobine abgewickelten Papieres. Bei den Versuchen stellte sich auch heraus, daß die verwendeten wasserlöslichen Bindemittel erhebliche Probleme mit sich bringen, nicht nur bei der Bedruckung und der nachfolgenden Trocknung, sondern auch bis zum Zigarettenverbraucher hin, bei dem sich die Druckfarbe an der Lippe löste, weil das verwendete Bindemittel nicht speichelfest war: Aus diesem Grunde werden bis heute lediglich Bindemittel verwendet, die zu ihrer Verarbeitung organischer Lösungsmittel bedürfen.Attempts to use water as a solvent in the printing ink, which would make the printing ink more flame retardant and more easily extinguished in the event of fire, have so far failed because the papers which can be used as base paper are unsuitable for printing with colors containing water as a solvent for a number of reasons: In experiments, the base paper curled after the printing process and when it was wound onto the reel, the printed image was not perfect, but was washed out due to the base paper being too water absorbent, and the crimped paper could not be processed on the cigarette machines because its tear strength had decreased, too The smooth entry of the paper into the machine was no longer guaranteed and there were therefore continuous production interruptions due to the paper being unwound from the reel. The experiments also found that the water-soluble binders used pose significant problems, not only in terms of printing and subsequent drying, but also to the cigarette consumer, where the ink on the lip loosened because the binder used was not resistant to saliva: For this reason, only binders are used that require organic solvents to be processed.
Es ist die Aufgabe der Erfindung, ein Zigarettenmundstücksbelagpapier der eingangs genannten Art dahingehend zu verbessern, daß eine umweltfreundliche Herstellung bei einer verbesserten Qualität des Zigarettenmundstücksbelagpapieres möglich wird.It is the object of the invention to improve a cigarette mouthpiece covering paper of the type mentioned at the outset in such a way that environmentally friendly production is possible with an improved quality of the cigarette mouthpiece covering paper.
Die Erfindung besteht darin, daß als Papier ein Basispapier verwendet wird, welches im Cobb-Test eine Wasseraufnahmefähigkeit von 6 - 12 g/m² in60 sec aufweist, daß als Lösungsmittel in der Druckfarbe Wasser zumindest zu 60 % verwendet wird und daß als Bindemittel für die Pigmente Schellack verwendet wird.The invention consists in that a base paper is used as paper which in the Cobb test has a water absorption capacity of 6-12 g / m 2 in 60 seconds, that at least 60% of water is used as solvent in the printing ink and that as a binder for the Pigments shellac is used.
Ein derartiges Zigarettenmundstücksbelagpapier hat den Vorteil, daß der Druck ein verbessertes Bild gibt, was darauf zurückzuführen sein dürfte, daß bei der Verwendung von Schellack an der Oberfläche Pigmente freiliegen, die bei den bisher verwendeten Bindemitteln voll vom Bindemittel umschlossen waren.Darüber hinaus ist ein Lösen der Druckfarbe durch Feuchtigkeits- oder Wassereinwirkung an den Lippen des Verbrauchers nicht möglich, weil der Schellack nach seinem Festwerden im Trocknungsvorgang nach dem Druckvorgang nicht mehr durch einfache Wassereinwirkung lösbar ist. Dieses ist auch der Grund dafür, daß das an seiner dem Papier abgekehrten Oberfläche freiliegende Pigment nicht von dem Papier bzw. dem Bindemittel zwischen dem Pigment und dem Papier abgelöst werden kann. Darüber hinaus sind auch erhebliche Vorteile bei der Verarbeitung erzielt: Die Trocknung des Lösungsmittels Wasser bringt keinerlei Umweltprobleme mit sich. Die Druckfarbe ist bei Brand mit Wasser löschbar, so sie überhaupt in Brand gerät. Das ist auch ein Vorteil beim Transport und bei der Lagerung, weil hier keine besonderen Vorsichtsmaßnahmen gegenüber Feuer zu ergreifen sind.Such a cigarette tip paper has the advantage that the print gives an improved picture, which may be due to the fact that when using shellac on the surface, pigments are exposed which were completely enclosed by the binder in the previously used binders the printing ink due to moisture or water on the lips of the consumer is not possible because the shellac after it has solidified in the drying process after the printing process can no longer be solved by simple water. This is also the reason why the pigment exposed on its surface facing away from the paper cannot be detached from the paper or the binder between the pigment and the paper. In addition, there are also considerable advantages in processing: Drying water as a solvent does not pose any environmental problems. The ink can be extinguished with water in the event of fire, if it catches fire at all. That is also a Advantage during transport and storage because no special precautionary measures against fire have to be taken.
Hier wirken das besondere Basispapier, das besondere Lösungsmittel und das ausgewählte Bindemittel zu einem einheitlichen technischen Erfolg zusammen: Es entsteht durch dieses Zusammenwirken einerseits eine erleichterte Verarbeitung und andererseits ein besonders gutes Bild bei sehr festhaftendem, nicht durch Speichel lösbarem Pigment- oder Bindemittelteil.This is where the special base paper, the special solvent and the selected binder work together to form a uniform technical success: this interaction creates easier processing on the one hand and a particularly good image with a very firmly adhering pigment or binder part that cannot be removed by saliva.
Man kann als Lösungsmittel in der Druckfarbe Wasser zu 100 % verwenden. Es kann aber auch Anwendungsfälle geben, in denen neben dem Wasser alsLösungsmittel auch Alkohole verwendet werden, um die Vorteile eines Azeotropengemisches zu nutzen. Da die Verwendung desLösungsmittels Alkohol jedoch nur in begrenztem Umfange stattfinden wird, ergeben sich hierdurch keine Schwierigkeiten hinsichtlich der Umweltbelastung, es ergeben sich auch keine Nachteile am Produkt.100% water can be used as a solvent in the printing ink. However, there may also be applications in which alcohols are used in addition to water as a solvent in order to take advantage of an azeotrope mixture. However, since the use of the solvent alcohol will only take place to a limited extent, there are no difficulties with regard to environmental pollution and there are no disadvantages to the product.
Es wird ein Zigarettenmundstücksbelagpapier mit einem hellbraunen Basispapier hergestellt, welches 3o g/m² Gewicht und eine Wasseraufnahmefähigkeit von 9 g/m² in 60 sec. im Cobb-Test aufweist. Dieses Basispapier wird mit einer Druckfarbe bedruckt, die als Lösungsmittel 9o % Wasser und 1o % Äthylalkohol enthält. Als Bindemittel dient Schellack.Es werden die üblichen Pigmente in folgender Zusammensetzung verwendet:
40 % Lösungsmittel
15 % Schellack
35 % Pigmente,
die sich aus Mischungen von Eisenoxyd und Titanoxyd zusammensetzen. Diese Druckfarbe wurde auf einer üblichen Druckmaschine auf das Basispaier aufgebracht, wie sie jahrelang bereits in derHerstellung von Zigarettenmundstücksbelagpapier verwendet wurde. Es ergaben sich bei gleichen Trocknungszeiten gegenüber Druckfarben mit organischen Lösungsmitteln verbesserte Bilder.A cigarette tip paper is produced with a light brown base paper, which has 3o g / m² weight and a water absorption capacity of 9 g / m² in 60 seconds in the Cobb test. This base paper is printed with a printing ink containing 9o% water and 1o% ethyl alcohol as a solvent. Shellac is used as a binding agent used in the following composition:
40% solvent
15% shellac
35% pigments,
which are composed of mixtures of iron oxide and titanium oxide. This ink was applied to the base paper on a conventional printing machine, as has been used for years in the manufacture of cigarette tip paper. With the same drying times, there were improved images compared to printing inks with organic solvents.
