  • the invention relates to paper or cardboard with a coating consisting of primer and top coat to create an aroma and vapor barrier.

  • the papers or cartons so formed are used, for example, as giant wrapping paper with moisture protection, heat-sealable packaging paper for the production of armored packaging for paper rolls, packaging paper with moisture protection, packaging material for food, aroma protection packaging, packaging for liquid Food, packaging for bulk goods, washing powder packaging, insulation paper for the construction industry, wallpaper paper and as a problem-free material in the recycling process.
  • What is required of the paper or cardboard while maintaining all the essential advantages of these papers or cardboard is a sufficient vapor and aroma density that they continue to be food-safe and continue to be oil and fat repellent.
  • they must be tasteless and odorless, bondable with special adhesives, sealable against themselves and other plastic coatings.
  • PVDC polyvinyldenchloride
  • vapor and aroma barriers have been achieved by coatings which are a mixture of several, preferably three, polymers, namely paraffin, carboxylated styrene butadiene as well as polyarcylate (EP-OS 0 393 451).
  • the disadvantage of this coating is that the coating slip can contain a great deal of wax in order to achieve the necessary vapor and aroma barrier. This expenditure of additional material means higher costs, as well as problems with recycling and heat sealing.
  • DE-OS 42 27 184 discloses an impregnating agent for the production of papers to achieve penetration resistance against fats, oils and aqueous media. Surface sizing takes place, in particular by means of a size press in the paper machine. However, the penetration resistance achieved with these processes is only slight and is in no way a vapor barrier.
  • the invention is based on the object to provide an improved paper or an improved box of a group consisting of primer and top coat coating to create an aroma and vapor barrier.
  • the primer in the coating slip consists of the components water, amorphous silicon dioxide, aluminum oxide, polyvinyl alcohol and a copolymer of styrene-butadiene and acrylonitrile or of the components water, silica or precipitated silica, polyvinyl alcohol and a copolymer of styrene butadiene and acrylonitrile.
  • the idea of the invention consists in a very special combination coat for creating the barrier in the sense of a synergetic effect, namely as a step essential to the invention, the linking of the special primer according to the invention with already known barrier coat coats as a top coat.
  • the primers described improve the properties of these top coats, which have so far been used insufficiently, and achieve with regard to the total coat weight with conventional ones PE coatings have comparable barrier values.

  • the special selection of the individual components in the primer guarantees a saturation of the capillary fiber structure of the paper or cardboard after the polymerization and fills absorption-promoting spaces or covers them with an amorphous network structure.
  • the openings remaining in the primer are sufficient to anchor the top coat well, effectively preventing it from kicking away. It is thus achieved that the aqueous components necessary for optimal polymerization remain in the top coat mass long enough and an improved arrangement of the film-forming molecules is produced.
  • the essence of the invention is thus that, in order to achieve the required barrier, an arbitrary top coat which creates a vapor barrier is applied to a special primer of the invention.
  • a barrier effect from the primer alone cannot be measured in accordance with DIN 53122 Klima D (over 135 g / m2 / 24h).
  • the primer almost completely prevents the migration of polymer dispersions of the top coat into the paper or cardboard. This results in improved crosslinking and thus a denser film build-up, as well as the reduction in the amount of application required, which results in a thin layer thickness.
  • the combination coat according to the invention with a specific primer coat and with a further top coat suitable for producing a vapor barrier has all the essential advantages of the previous PE-coated papers or cartons and thus represents a full substitute for these.
  • Papers and boxes are food-safe, oil and grease repellent, tasteless and odorless, can be glued with special adhesives, sealable against themselves and other plastic coatings.
  • the papers or cardboard boxes according to the invention can be easily recycled and have a relatively low application weight.
  • the return of the papers or cardboard boxes according to the invention to the material cycle is much easier and therefore less expensive.
  • the high barrier layer values already achieved with relatively low application weights mean that resources can be saved in comparison with the previous coating processes, in particular also in comparison with the PE coatings.

Darüber hinaus müssen sie geschmacks- und geruchsneutral, verklebbar mit speziellen Klebern, siegelfähig gegen sich selbst und andere Kunststoffbeschichtungen sein. Darüber hinaus sollten sie problemlos der Wiederverwertung zugeführt werden können und ein relativ geringes Auftragsgewicht haben.Papers or boxes coated in this way to create an aroma and vapor barrier have a variety of uses. Depending on the respective certification of the top coat component (s) used and their layer thickness, the papers or cartons so formed are used, for example, as giant wrapping paper with moisture protection, heat-sealable packaging paper for the production of armored packaging for paper rolls, packaging paper with moisture protection, packaging material for food, aroma protection packaging, packaging for liquid Food, packaging for bulk goods, washing powder packaging, insulation paper for the construction industry, wallpaper paper and as a problem-free material in the recycling process. What is required of the paper or cardboard while maintaining all the essential advantages of these papers or cardboard is a sufficient vapor and aroma density that they continue to be food-safe and continue to be oil and fat repellent. In addition, they must be tasteless and odorless, bondable with special adhesives, sealable against themselves and other plastic coatings. In addition, they should be able to be recycled without problems and have a relatively low order weight.

Bisher ist es bekannt, zur Schaffung derartiger Papiere oder Kartons diese mit einer Polyäthylen-Beschichtung zu versehen. Allerdings ist wegen der allgemein bekannten Probleme beim Recycling von PE-beschichteten Papieren oder Kartons diese Art von Beschichtung doch mit erheblichen Nachteilen behaftet.So far, it is known to provide such papers or boxes with a polyethylene coating. However, because of the well-known problems when recycling PE-coated paper or cardboard, this type of coating has considerable disadvantages.

Weiterhin wurden als Alternative zu der PE-Beschichtung zur Lösung der damit verbundenen Problematiken Beschichtungen mittels Polyvinyldenchlorid (PVDC) mit mindestens 15 g/m² durchgeführt (EP-OS 0 375 924). Diese PVDC-Beschichtungen haben jedoch den Nachteil der Chlorverbindung. Außerdem muß auf den Barrierestrich aus PVDC ein weiterer Mineralstrich aufgetragen werden, um eine Bedruckung durchführen zu können. Dies stellt allerdings ein umständliches Verfahren dar.Furthermore, as an alternative to the PE coating to solve the associated problems, coatings using polyvinyldenchloride (PVDC) with at least 15 g / m 2 were carried out (EP-OS 0 375 924). However, these PVDC coatings have the disadvantage of the chlorine compound. In addition, another mineral coat must be applied to the PVDC barrier screed in order to be able to print. However, this is a cumbersome process.

Mittlerweile erzielt man Dampf- und Aromasperren durch Beschichtungen, die eine Mischung von mehreren, vorzugsweise drei Polymeren, nämlich Paraffin, carboxyliertes Styrolbutadien sowie Polyarcylat darstellen (EP-OS 0 393 451). Der Nachteil dieser Beschichtung liegt darin, daß in der Streichmasse sehr viel Wachs enthalten sein kann, um die notwendige Dampf- und Aromasperre zu erzielen. Dieser Aufwand an Mehrmaterial bedeutet höhere Kosten, sowie vor allem Probleme beim Recycling und der Heißsiegelfähigkeit.In the meantime, vapor and aroma barriers have been achieved by coatings which are a mixture of several, preferably three, polymers, namely paraffin, carboxylated styrene butadiene as well as polyarcylate (EP-OS 0 393 451). The disadvantage of this coating is that the coating slip can contain a great deal of wax in order to achieve the necessary vapor and aroma barrier. This expenditure of additional material means higher costs, as well as problems with recycling and heat sealing.

In der DE-OS 42 27 184 ist ein Imprägniermittel zur Herstellung von Papieren zur Erzielung eines Durchdringungswiderstandes gegen Fette, Öle und wässrige Medien offenbart. Dabei erfolgt eine Oberflächenleimung, insbesondere mittels einer Leimpresse in der Papiermaschine. Allerdings ist der bei diesen Verfahren erzielte Durchdringungswiderstand nur geringfügig und keinesfalls eine Dampfbarriere.DE-OS 42 27 184 discloses an impregnating agent for the production of papers to achieve penetration resistance against fats, oils and aqueous media. Surface sizing takes place, in particular by means of a size press in the paper machine. However, the penetration resistance achieved with these processes is only slight and is in no way a vapor barrier.

Der Mangel der bisher bekannten Papiere oder Kartons besteht darin, daß die für viele Verpackungszwecke erforderlichen Dampf- und Aromadichten sich nur mit sehr dicken Schichten erreichen lassen, die teilweise nur bei mehrfach aufgetragenen Vor- und Deckstrichen erzielt werden, wobei der Vorstrich die Aromasperre und der Deckstrich die Dampfsperre gewährleisten soll. Der in diesen Strichen enthaltene Wachsanteil erreicht jedoch Größenordnungen, die einer problemlosen Rückführung zur Wiederverwertung entgegenstehen.The lack of the previously known papers or cardboard boxes is that the vapor and aroma densities required for many packaging purposes can only be achieved with very thick layers, some of which can only be achieved with multiple primers and top coats, the primer being the aroma barrier and Top coat to ensure the vapor barrier. However, the amount of wax contained in these lines reaches orders of magnitude that prevent easy recycling for recycling.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, ein verbessertes Papier oder einen verbesserten Karton mit einer aus Vorstrich und Deckstrich bestehenden Beschichtung zur Schaffung einer Aroma- und Dampfsperre zu schaffen.On this basis, the invention is based on the object to provide an improved paper or an improved box of a group consisting of primer and top coat coating to create an aroma and vapor barrier.

Als technische Lösung wird mit der Erfindung vorgeschlagen, daß der Vorstrich in der Streichmasse aus den Komponenten Wasser, amorphes Siliciumdioxid, Aluminiumoxid, Polyvinylalkohol und einem Copolymer von Styrol-Butadien und Acrylnitril oder aus den Komponenten Wasser, Kieselsäure oder gefällte Kieselsäure, Polyvinylalkohol und einem Copolymer von Styrol-Butadien und Acrylnitril besteht.The invention proposes as a technical solution that the primer in the coating slip consists of the components water, amorphous silicon dioxide, aluminum oxide, polyvinyl alcohol and a copolymer of styrene-butadiene and acrylonitrile or of the components water, silica or precipitated silica, polyvinyl alcohol and a copolymer of styrene butadiene and acrylonitrile.

Dadurch ist ein Papier oder ein Karton mit einer verbesserten (Wasser-)Dampf- und Aromadichte geschaffen, wobei beliebiges Rohpapier, beispielsweise auch Recyclingpapier, oder beliebiger Karton verwendet werden kann, auf den zunächst der Vorstrich und anschließend der Deckstrich aufgetragen wird. Die Erfindungsidee besteht dabei in einem ganz speziellen Kombinationsstrich zur Erstellung der Sperre im Sinne eines synergetischen Effektes, nämlich als erfindungswesentlicher Schritt die Verknüpfung des speziellen, erfindungsgemäßen Vorstriches mit bereits bekannten Sperrschichtstrichen als Deckstrich. Die beschriebenen Vorstriche verbessern die bislang nur unzureichend genutzten Eigenschaften dieser Deckstriche erheblich und erzielen im Hinblick auf das Gesamtstrichgewicht mit herkömmlichen PE-Beschichtungen vergleichbare Barrierewerte. Der erfindungsgemäße Vorstrich dringt dabei fast vollständig in den Oberflächenbereich des Papiers oder Kartons ein. Die spezielle Auswahl der einzelnen Komponenten im Vorstrich garantiert nach der Polymerisation eine Saturierung der kapillaren Faserstruktur des Papiers oder Kartons und füllt absorptionsfördernde Zwischenräume aus oder überzieht diese mit einer amorphen Netzstruktur. Bei einer entsprechend abgestimmten Rheologie des Deckstriches reichen die im Vorstrich verbleibenden Öffnungen zu einer guten Verankerung des Deckstriches aus, wobei ein Wegschlagen wirksam unterbunden wird. Somit wird erreicht, daß die zu einer optimalen Polymerisation notwendigen wässrigen Bestandteile lange genug in der Deckstrichmasse bleiben und eine verbesserte Anordnung der filmbildenden Moleküle entsteht. Der erfindungswesentliche Kern liegt somit darin, daß zur Erzielung der geforderten Barriere ein eine Dampfsperre erzeugender, beliebiger Deckanstrich auf einen speziellen Vorstrich der Erfindung aufgetragen wird. So ist eine Barrierewirkung durch den Vorstrich alleine gemäß DIN 53122 Klima D nicht meßbar (über 135 g/m²/24h). Allerdings verhindert der Vorstrich fast vollständig die Migration von Polymerdispersionen des Deckstrichs in das Papier oder den Karton. Daraus resultiert eine verbesserte Vernetzung und damit ein dichterer Filmaufbau, ebenso wie die Reduzierung der erforderlichen Auftragsmenge, welche in einer dünnen Schichtdicke resultiert. Der erfindungsgemäße Kombinationsstrich mit einem bestimmten Vorstrich sowie mit einem weiteren, zur Erzeugung einer Dampfsperre geeigneten Deckstrich besitzt alle wesentlichen Vorteile der bisherigen PE-beschichteten Papiere oder Kartons und stellt somit einen vollwertigen Ersatz für diese dar. Diese Vorteile sind ausreichende Dampf- und Aromadichte, die Papiere und Kartons sind lebensmittelrechtlich unbedenklich, öl- und fettabweisend, geschmacks- und geruchsneutral, verklebbar mit speziellen Klebern, siegelfähig gegen sich selbst und andere Kunststoffbeschichtungen. Vor allem sind die erfindungsgemäßen Papiere oder Kartons problemlos der Wiederverwertung zuführbar und weisen ein relativ geringes Auftragsgewicht auf. So ist die Rückführung der erfindungsgemäßen Papiere oder Kartons in den Wertstoffkreislauf im Gegensatz zu den herkömmlichen PE-beschichteten Substraten wesentlich einfacher möglich und damit kostengünstiger. Durch die schon bei relativ geringen Auftragsgewichten realisierten hohen Sperrschichtwerte können im Vergleich zu den bisherigen Beschichtungsverfahren, insbesondere auch im Vergleich zu den PE-Beschichtungen Resourcen gespart werden. Somit sind die nach dem erfindungsgemäßen Verfahren gestrichenen Papiere oder Kartons abhängig von der jeweiligen Zertifizierung der verwendeten Deckstrichkomponente(n) und deren Schichtdicke als Rieseinschlagpapier mit Feuchtigkeitsschutz, heißsiegelfähigem Packpapier zur Herstellung von Panzerverpackungen für Papierrollen, Packpapier mit Feuchtigkeitsschutz, Verpackungsmittel für Lebensmittel, Aromaschutzverpackungen, Verpackungen für flüssige Lebensmittel, Verpackungen für Schüttgüter, Waschpulververpackungen, Isolationspapiere für die Bauindustrie, Tapetenpapiere etc. verwendbar.This creates a paper or cardboard with an improved (water) vapor and aroma density, it being possible to use any base paper, for example also recycled paper, or any cardboard to which the primer coat and then the top coat coat are applied. The idea of the invention consists in a very special combination coat for creating the barrier in the sense of a synergetic effect, namely as a step essential to the invention, the linking of the special primer according to the invention with already known barrier coat coats as a top coat. The primers described improve the properties of these top coats, which have so far been used insufficiently, and achieve with regard to the total coat weight with conventional ones PE coatings have comparable barrier values. The primer according to the invention penetrates almost completely into the surface area of the paper or cardboard. The special selection of the individual components in the primer guarantees a saturation of the capillary fiber structure of the paper or cardboard after the polymerization and fills absorption-promoting spaces or covers them with an amorphous network structure. With an appropriately coordinated rheology of the top coat, the openings remaining in the primer are sufficient to anchor the top coat well, effectively preventing it from kicking away. It is thus achieved that the aqueous components necessary for optimal polymerization remain in the top coat mass long enough and an improved arrangement of the film-forming molecules is produced. The essence of the invention is thus that, in order to achieve the required barrier, an arbitrary top coat which creates a vapor barrier is applied to a special primer of the invention. A barrier effect from the primer alone cannot be measured in accordance with DIN 53122 Klima D (over 135 g / m² / 24h). However, the primer almost completely prevents the migration of polymer dispersions of the top coat into the paper or cardboard. This results in improved crosslinking and thus a denser film build-up, as well as the reduction in the amount of application required, which results in a thin layer thickness. The combination coat according to the invention with a specific primer coat and with a further top coat suitable for producing a vapor barrier has all the essential advantages of the previous PE-coated papers or cartons and thus represents a full substitute for these. These advantages are sufficient vapor and aroma density which Papers and boxes are food-safe, oil and grease repellent, tasteless and odorless, can be glued with special adhesives, sealable against themselves and other plastic coatings. Above all, the papers or cardboard boxes according to the invention can be easily recycled and have a relatively low application weight. In contrast to the conventional PE-coated substrates, the return of the papers or cardboard boxes according to the invention to the material cycle is much easier and therefore less expensive. The high barrier layer values already achieved with relatively low application weights mean that resources can be saved in comparison with the previous coating processes, in particular also in comparison with the PE coatings. Thus, the papers or boxes coated by the method according to the invention are dependent on the respective certification of the top coat component (s) used and their layer thickness as ream wrapping paper with moisture protection, heat-sealable packaging paper for the production of armored packaging for paper rolls, packaging paper with moisture protection, packaging material for food, aroma protection packaging, packaging for liquid food, packaging for bulk goods, washing powder packaging, insulation paper for the construction industry, Wallpaper papers etc. can be used.

In einer Weiterbildung des Vorstrichs enthält dieser zusätzlich noch Stärke.In a further development of the primer, it also contains starch.

Vorzugsweise beträgt die Auftragsmenge des Vorstrichs 2,5 bis 5 g/m². Dabei hängt die Auftragsmenge von der Beschaffenheit des Rohpapiers oder des Kartons ab.The application amount of the primer is preferably 2.5 to 5 g / m 2. The order quantity depends on the nature of the base paper or the cardboard.

Eine weitere Weiterbildung schlägt vor, daß der Deckstrich in der Streichmasse eine Polymerdispersion oder eine Mischung von mehreren Polymerdispersionen aufweist. Dabei kann es sich beispielsweise um Ethylene/Methacrylat, Polyvinylacetat, Styrol-Butadien oder der daraus abgeleiteten Copolymere handeln. Wesentlich bei diesen Polymerdispersionen ist die Tatsache, daß diese Komponenten, die für sich allein genommen nur relativ geringe Dampfdichten von ungefähr 15 bis 20 g/m²/24h (bei Auftragsmengen von 20 g/m² Trockengewicht) erzielen, in Verbindung mit dem speziellen, erfindungsgemäßen Vorstrich jedoch erheblich höhere Barrierewirkungen, nämlich 4 bis 10 g/m²/24h bei deutlich reduzierten Auftragsmengen (5 bis 10 g/m²) erreichen. Die Auftragsmenge des Vorstriches liegt dabei je nach Beschaffenheit des Rohpapieres zwischen 2,5 und 5 g/m². Eine Barrierewirkung nach DIN 53122 Klima D durch den Vorstrich allein ist nicht meßbar (über 135 g/m²/24h). Allerdings verhindert der erfindungsgemäße Vorstrich fast vollständig die Migration von Polymerdispersionen in das Papier oder den Karton. Daraus resultiert eine verbesserte Vernetzung und damit ein dichterer Filmaufbau ebenso wie die Reduzierung der erforderlichen Auftragsmenge (Schichtdicke).A further development suggests that the top coat in the coating slip has a polymer dispersion or a mixture of several polymer dispersions. This can be, for example, ethylene / methacrylate, polyvinyl acetate, styrene-butadiene or the copolymers derived therefrom. It is essential with these polymer dispersions that these components, which on their own only achieve relatively low vapor densities of approximately 15 to 20 g / m 2/24 h (with application amounts of 20 g / m 2 dry weight), in connection with the special inventive However, primer can achieve significantly higher barrier effects, namely 4 to 10 g / m² / 24h with significantly reduced application quantities (5 to 10 g / m²). The application quantity of the primer is between 2.5 and 5 g / m² depending on the nature of the base paper. A barrier effect according to DIN 53122 Klima D by the primer alone is not measurable (over 135 g / m² / 24h). However, the primer according to the invention almost completely prevents the migration of polymer dispersions into the paper or cardboard. This results in improved networking and thus a denser film build-up, as well as a reduction in the required application quantity (layer thickness).

Eine weitere Weiterbildung des Deckstriches in der Streichmasse schlägt vor, daß er aus den Grundstoffen Wasser, einem mit Carnauba- und Paraffinwachs modifizierten Copolymer von Styrol und Butadien, einer Ethylene/Methacrylsäuredispersion sowie Polyvinylacetat besteht. Somit ist aus den genannten Grundstoffen zur Erzielung einer Dampfsperre ein entsprechend geeigneter Deckstrich zusammensetzbar. Dabei können Teilkombinationen aus diesen Komponenten gebildet werden. Gefordert ist lediglich, daß diese Kombination eine wirkungsvolle Dampfsperre erzielt.A further development of the top coat in the coating slip suggests that it consists of the basic materials water, a copolymer of styrene and butadiene modified with carnauba and paraffin wax, an ethylene / methacrylic acid dispersion and polyvinyl acetate. A suitable top coat can thus be assembled from the above-mentioned basic materials to achieve a vapor barrier. Part combinations can be formed from these components. The only requirement is that this combination achieves an effective vapor barrier.

Eine weitere Weiterbildung des Deckstriches in der Streichmasse schlägt vor, daß dieser aus den Komponenten Wasser sowie einem mit Carnauba- und Paraffinwachs modifizierten Copolymer von Styrol und Butadien oder aus den Komponenten Wasser sowie einer Ethylene/Methacrylsäuredispersion oder aus den Komponenten Wasser sowie carboxyliertem Styrol-Butadien oder aus den Komponenten Wasser sowie einer Styrol-Acrylat-Copolymerdispersion besteht. Mit diesen Kombinationen wird eine optimale Dampfsperre erzeugt, so daß in optimaler Weise der bereits zuvor geschilderte synergetische Effekt zusammen mit den speziellen Vorstrichen erzielt wird.A further development of the top coat in the coating slip suggests that it consists of the components water and a copolymer of styrene and butadiene modified with carnauba and paraffin wax or of the components water and an ethylene / methacrylic acid dispersion or of the components water and carboxylated styrene-butadiene or consists of the components water and a styrene-acrylate copolymer dispersion. With these combinations, an optimal vapor barrier is generated so that the synergetic effect described above is optimally achieved together with the special primers.

Dabei kann der Deckstrich einen zusätzlichen Strich mit einer Streichmasse aus den Komponenten Wasser und einer Sryrol-Acrylat-Copolymerdispersion enthalten.The top coat can contain an additional coat with a coating slip composed of the components water and a Sryrol-Acrylate copolymer dispersion.

Eine weitere Weiterbildung des Deckstriches schlägt vor, daß dem Deckstrich ein Polyvinylacetat beigemischt ist.A further development of the top coat suggests that a poly vinyl acetate is added to the top coat.

Die Auftragsmenge des Deckstriches beträgt vorzugweise 5 bis 10 g/m². Diese Schichtdicke reicht bei den angegebenen Deckstrichen aus, um eine optimale Dampfsperre zu erzielen.The application amount of the top coat is preferably 5 to 10 g / m². With the specified top coats, this layer thickness is sufficient to achieve an optimal vapor barrier.

Weiterhin wird in einer Weiterbildung vorgeschlagen, daß der Auftrag des Vor- und Deckstriches mittels Rollrakel, Gravursystemen oder mittels Modifikationen davon erfolgt. Der Auftrag des Vor- und Deckstriches kann somit mittels bekannter Streichtechniken erzielt werden, die zur Erzielung von dünnen Streichschichten geeignet sind. Vorzugsweise werden dabei Maschinen mit zwei Streichwerken verwendet.Furthermore, it is proposed in a further development that the application of the primer and top coat is carried out by means of a doctor blade, engraving systems or by means of modifications thereof. The application of the precoat and top coat can thus be achieved by means of known coating techniques which are suitable for achieving thin coating layers. Machines with two coating units are preferably used.

Außerdem wird in einer Weiterbildung vorgeschlagen, daß das Papier oder der Karton beidseitig beschichtet ist. Die Beschichtungen können dabei selbstverständlich entsprechend den jeweiligen Erfordernissen auf den beiden Seiten unterschiedlich sein, wobei die verschiedensten Kombinationen der erfindungsgemäßen Vor- und Deckstriche denkbar sind.It is also proposed in a further development that the paper or the cardboard is coated on both sides. The coatings can of course be different on the two sides in accordance with the respective requirements, the most varied combinations of the primers and top coats according to the invention being conceivable.

Schließlich wird in einer Weiterbildung vorgeschlagen, daß das Papier oder der Karton oberflächengeleimt ist. Dadurch wird die Papier- oder Kartonoberfläche verdichtet und unterstützt somit die Wirkung des Vorstrichs.Finally, it is proposed in a further development that the paper or the cardboard is surface-sized. This compresses the paper or cardboard surface and thus supports the effect of the primer.

Ein Ausführungsbeispiel eines erfindungsgemäßen Papieres oder Kartons wird nachfolgend anhand der Zeichnung beschrieben. Diese zeigt in einer rein schematischen Darstellung eine Art Schnitt durch ein derartiges Papier oder Karton, welches zunächst mit einem Vorstrich und anschließend mit einem Deckstrich zur Schaffung einer Aroma- und Dampfsperre beschichtet worden ist.An embodiment of a paper or cardboard according to the invention is described below with reference to the drawing. In a purely schematic representation, this shows a kind of section through such paper or cardboard, which has been coated first with a primer and then with a top coat to create an aroma and vapor barrier.

In der Zeichnung ist zunächst das Papier oder der Karton 1 in rein schematischer Weise zu erkennen. Es kann sich dabei beispielsweise auch um Recyclingpapier handeln.In the drawing, the paper or cardboard 1 can first be seen in a purely schematic manner. It can also be recycled paper, for example.

Auf das Papier oder den Karton 1 ist ein Vorstrich 2 aufgetragen. Die chemische Zusammensetzung dieses Vorstrichs 2 ist zuvor beschrieben worden. Dabei ist in der Zeichnung erkennbar, daß der Vorstrich 2 fast vollständig in den Oberflächenbereich des Papiers oder Kartons 1 eindringt. Die spezielle Auswahl der einzelnen Komponenten in diesem Vorstrich 2 garantiert nach der Polymerisation eine Saturierung der kapillaren Faserstruktur des Substrats und füllt absorptionsfördernde Zwischenräume aus bzw. überzieht diese mit einer amorphen Netzstruktur. Bei einer entsprechend abgestimmten Rheologie des auf den Vorstrich 2 anschließend aufgebrachten Deckstriches 3 reichen die im Vorstrich 2 verbleibenden Öffnungen zu einer guten Verankerung dieses Deckstriches 3 aus, wobei ein Wegschlagen wirksam unterbunden wird. So wird erreicht, daß die zu einer optimalen Polymerisation notwendigen wässrigen Bestandteile lange genug in der Deckstrichmasse bleiben und eine verbesserte Anordnung der filmbildenden Moleküle entsteht. Die so geschaffenen Papiere oder Kartons 1 verbessern die bislang nur unzureichend genutzten Eigenschaften dieser Deckstriche 3 erheblich und erzielen im Hinblick auf das Gesamtstrichgewicht mit herkömmlichen PE-Beschichtungen vergleichbare Barrierewerte. Der große Vorteil liegt dabei in der Rückführung der mit den beschriebenen Verfahren beschichteten Papier oder Kunststoffe 1 in den Wertstoffkreislauf. Diese Rückführung ist im Gegensatz zu PE-beschichteten Substraten wesentlich einfacher möglich und damit kostengünstiger. Weiterhin können durch die schon bei relativ geringen Auftragsgewichten realisierten hohen Sperrschichtwerte im Vergleich zu den bisherigen Beschichtungsverfahren Resourcen eingespart werden. Darüber hinaus ist es ohne weiteres möglich, auch Recyclingpapiere zu verwenden.A primer 2 is applied to the paper or cardboard 1. The chemical composition of this primer 2 has been previously described. It can be seen in the drawing that the primer 2 penetrates almost completely into the surface area of the paper or cardboard 1. The special selection of the individual components in this primer 2 guarantees saturation of the capillary fiber structure of the substrate after the polymerization and fills absorption-promoting interstices or covers them with an amorphous network structure. With a correspondingly coordinated rheology of the top coat 3 subsequently applied to the primer 2, the openings remaining in the primer 2 are sufficient for anchoring this top coat 3, effectively preventing kicking away. The result is that the aqueous constituents necessary for optimal polymerization remain in the top coat mass long enough and an improved arrangement of the film-forming molecules is produced. The papers or boxes 1 created in this way considerably improve the properties of these top coats 3, which have hitherto been inadequately used, and achieve barrier values which are comparable with conventional PE coatings with regard to the total coat weight. The great advantage lies in the return of the paper or plastics 1 coated with the described methods to the recycling cycle. In contrast to PE-coated substrates, this recycling is much easier and therefore cheaper. Furthermore, the high junction values achieved even with relatively low application weights mean that resources can be saved in comparison with the previous coating processes. In addition, it is easily possible to use recycled paper.

In dem dargestellten Ausführungsbeispiel ist eine einseitige Beschichtung vorgesehen. Selbstverständlich ist es auch denkbar, sowohl die Vorder- als auch die Rückseite des Papiers oder Kartons 1 jeweils mit einer erfindungsgemäßen Beschichtung zu versehen.In the illustrated embodiment, a one-sided coating is provided. Of course, it is also conceivable to provide both the front and the back of the paper or cardboard 1 with a coating according to the invention.
