Description

Die vorliegende Erfindung betrifft ein Verfahren zum Herstellen eines metallisierten Verbundstoffes sowie einen metallisierten Verbundstoff.The present invention relates to a method for producing a metallized composite and a metallized composite.

Um einen Verlust von Aroma (Gasen) und Feuchtigkeit zu vermeiden, werden bestimmte Waren, wie beispielsweise Zigaretten, Kaffee oder ähnliches üblicherweise in einem Verbundstoff verpackt, der Aluminium- und Kunststoffolien oder auch Papier umfaßt. Hierbei wirkt die Aluminiumfolie, die eine Wasserdampfdurchlässigkeit von ungefähr 0 g/m²·d aufweist, als Barriere für Gase und Feuchtigkeit.In order to avoid loss of aroma (gases) and moisture, certain goods, such as cigarettes, coffee or the like, are usually packaged in a composite which comprises aluminum and plastic films or also paper. The aluminum foil, which has a water vapor permeability of approximately 0 g / m² · d, acts as a barrier for gases and moisture.

Da eine derartige Aluminiumfolie relativ hohe Kosten verursacht, wird auch ersatzweise auf metallisiertes Papier zurückgegriffen. Ein derartiges metallisiertes Papier besitzt eine aufgedampfte Metallschicht, wobei üblicherweise folgender Aufbau vorgesehen ist:

40-120 g/m²
gestrichenes Papier
0,5-2,5 g/m²
Grundierlack
200-500 Å
Metallisierung
0,5-2,5 g/m²
Decklack.
Since such an aluminum foil causes relatively high costs, metallized paper is also used as an alternative. Such a metallized paper has a vapor-deposited metal layer, the following structure usually being provided:
40-120 g / m²
coated paper
0.5-2.5 g / m²
Primer
200-500 Å
Metallization
0.5-2.5 g / m²
Top coat.

Die Wasserdampfdurchlässigkeit eines solchen Verbundstoffes liegt bei etwa 40-100 g/m²·d (gemessen nach DIN 53122), was jedoch für viele Anwendungen nicht ausreichend ist, da beispielsweise für Aromaverpackungen von Zigaretten und Kaffee eine Wasserdampfdurchlässigkeit von < 2 g/m²·d gefordert wird.The water vapor permeability of such a composite is around 40-100 g / m² · d (measured in accordance with DIN 53122), which is, however, not sufficient for many applications since, for example, for aromatic packaging of cigarettes and coffee, a water vapor permeability of <2 g / m² · d is required.

Um diese Anforderungen zu erfüllen, weisen andere bislang bekannten Lösungen ein Basispapier auf, das bereits in der Papierfabrik mehrschichtig mit Barrierebeschichtungen versehen worden ist. Derartige Barrierebeschichtungen umfassen beispielsweise Latexdispersionen mit Zusätzen von Pigmenten und Polymeren mit einem Flächengewicht von ca. 18-20 g/m². Auf dieses Basispapier sind dann eine oder mehrere weitere Barrierebeschichtungen sowie eine Grundierschicht, eine Metallisierungsschicht und ein Decklack aufgebracht, wodurch die erforderliche Wasserdampfdurchlässigkeit von < 2 g/m²·d gewährleistet sein soll.In order to meet these requirements, other previously known solutions have a base paper that has already been provided with multiple layers of barrier coatings in the paper mill. Such barrier coatings include, for example, latex dispersions with additions of pigments and polymers with a basis weight of approximately 18-20 g / m 2. One or more further barrier coatings as well as a primer layer, a metallization layer and a topcoat are then applied to this base paper, which should ensure the required water vapor permeability of <2 g / m 2 · d.

Andere bekannte Lösungen erreichen die geforderte Dichtigkeit durch Lackierungen mit Polyvinylchlorid oder Polyvinylidenchlorid mit einem Flächengewicht von 18-20 g/m². Derartige Lackierungen sind aber aus ökologischen Gründen äußerst bedenklich.Other known solutions achieve the required tightness by painting with polyvinyl chloride or polyvinylidene chloride with a basis weight of 18-20 g / m². However, such coatings are extremely questionable for ecological reasons.

Durch die Vielzahl der Arbeitsgänge, den hohen Preis und die großen ökologischen Nachteile der Barrierebeschichtungen sind die mit Barrierebeschichtungen versehenen Verbundstoffe gegenüber den Verbundstoffen mit Aluminiumfolie sehr teuer.Due to the large number of operations, the high price and the great ecological disadvantages of the barrier coatings, the composites provided with barrier coatings are very expensive compared to the composites with aluminum foil.

Es ist daher das der Erfindung zugrundeliegende Problem (Aufgabe), einen metallisierten Verbundstoff zu schaffen, der zum Verpacken von aroma- und feuchtigkeitshaltigen Produkten geeignet ist, wobei die Wasserdampfdurchlässigkeit des Verbundstoffes, d.h. dessen Sperrwirkung gegen Aroma-, Gas- und Feuchtigkeitsverlust gleich oder annähernd gleich einem aluminiumfolienhaltigen Verbundstoff ist. Dabei soll der erfindungsgemäße Verbundstoff einfach herstellbar und ökologisch wenig bedenklich sein.It is therefore the problem underlying the invention to provide a metallized composite which is suitable for packaging aroma and moisture-containing products, the water vapor permeability of the composite, i.e. whose barrier effect against loss of aroma, gas and moisture is the same or approximately the same as a composite containing aluminum foil. The composite material according to the invention should be simple to manufacture and should be of little ecological concern.

Die Lösung dieser Aufgabe erfolgt durch die Merkmale der Patentansprüche 1 oder 3.This object is achieved by the features of claims 1 or 3.

Erfindungsgemäß wird die geforderte niedrige Wasserdampfdurchlässigkeit von nahezu 0 g/m²·d dadurch erreicht, daß die an sich bekannten Beschichtungsvorgänge Grundierung und Metallisierung zweifach ausgeführt werden. Wie sich herausgestellt hat, wird durch Aufbringen einer zweiten Grundierung und einer zweiten Metallisierung auf die erste Grundierungsschicht eine hervorragende Sperrwirkung erzielt.According to the invention, the required low water vapor permeability of almost 0 g / m² · d is achieved in that the coating processes known per se, primer and metallization are carried out twice. As has been found, an excellent barrier effect is achieved by applying a second primer and a second metallization to the first primer layer.

Durch den erfindungsgemäßen Aufbau des Verbundstoffes können in vorteilhafter Weise übliche, preiswerte gestrichene Papiere oder Papiere mit einer vergleichbaren Oberflächenbeschaffenheit verwendet werden, die nicht mit einer speziellen Barrierebeschichtung versehen sind. Hierdurch wird der erfindungsgemäße Verbundstoff ökologisch unbedenklich und nicht kostenintensiv.As a result of the structure of the composite according to the invention, customary, inexpensive coated papers or papers with a comparable surface quality, which are not provided with a special barrier coating, can advantageously be used. As a result, the composite material according to the invention is ecologically harmless and not cost-intensive.

Aus der DE-OS 30 17 713 ist zwar ein Verfahren zur Beschichtung von Kunststoffolien mit Metallschichten bekannt, bei dem eine Haftschicht und eine Metallschicht nacheinander aufgebracht werden, wobei nach Aufbringen der Haftschicht zumindest eine Metallschicht aufgedampft wird. Jedoch werden die gegebenenfalls mehreren Metallschichten nicht nach zusätzlich vorgesehenen Grundier- oder Haftgrundaufträgen aufgebracht, sondern unmittelbar aufeinander. Zudem dient dieses bekannte Verfahren zum Herstellen von Leiterbahnen auf Kunststoffolien. Folglich soll die bekannte Metallschicht aus Stoffen hergestellt sein, die kein Eindifundieren von fremdartigen Ionen in die Metallschicht hervorrufen.From DE-OS 30 17 713 a method for coating plastic films with metal layers is known, in which an adhesive layer and a metal layer are applied one after the other, with at least one metal layer being evaporated after the adhesive layer has been applied. However, the possibly several metal layers are not applied according to additionally provided primer or adhesive primer applications, but directly on top of each other. In addition, this known method is used to produce conductor tracks on plastic films. Consequently, the known metal layer should be made of substances that do not cause foreign ions to diffuse into the metal layer.

Aus der DE-AS 12 25 939 ist ferner ein Verfahren zur Herstellung einer aus mehreren Lagen zusammengesetzten dünnen Schicht durch wiederholte Vakuumbedampfung bekannt. Hierbei liegt diesem bekannten Verfahren das Problem zugrunde, eine zusammengesetzte dünne Schicht zu schaffen, die gleichmäßig und porenfrei sein soll. Dieses bekannte Verfahren dient zur Herstellung von elektrisch isolierenden Kondensatorschichten, dient jedoch nicht zur Erstellung eines Verbundstoffes mit geringer Wasserdampfdurchlässigkeit.From DE-AS 12 25 939 a method for producing a thin layer composed of several layers by repeated vacuum evaporation is also known. This known method is based on the problem of creating a composite thin layer that is uniform and should be pore-free. This known method is used to produce electrically insulating capacitor layers, but is not used to create a composite with low water vapor permeability.

Schließlich ist aus der JP-52012311 ein Papier bekannt, das mit einer Aluminiummetallisierung versehen ist. Hierbei ist das Basispapier mit einem 15 µm dicken Polyethylenfilm beschichtet, der gewalzt wird. Durch eine Koronaentladung wird die Oberflächenenergie des Polyethylenfilms erhöht und anschließend wird der Film mit Aluminium metallisiert.Finally, a paper is known from JP-52012311, which is provided with an aluminum metallization. The base paper is coated with a 15 µm thick polyethylene film that is rolled. A corona discharge increases the surface energy of the polyethylene film and then the film is metallized with aluminum.

Vorteilhafte Ausführungsformen der Erfindung sind durch die Unteransprüche gekennzeichnet.Advantageous embodiments of the invention are characterized by the subclaims.

So kann das Basismaterial nach einer vorteilhaften Ausführung der Erfindung Papier oder Kunststoffolie sein. Da aufgrund des erfindungsgemäßen Aufbaus das Basismaterial keine besonderen Barrierebeschichtungen benötigt, kann übliches, preiswertes Papier oder übliche Kunststoffolie verwendet werden.According to an advantageous embodiment of the invention, the base material can be paper or plastic film. Since the base material does not require any special barrier coatings due to the structure according to the invention, customary, inexpensive paper or customary plastic film can be used.

Nach einer weiteren Ausbildung der Erfindung können die im Anspruch 5 angegebenen Flächengewichte, beziehungsweise Schichtdicken, vorgesehen sein. Durch einen derartigen Verbundstoff ergibt sich eine Wasserdampfdurchlässigkeit < 2 g/m²·d. Hierbei beträgt die Gesamtauftragsmenge von Grundierung und Deckschicht weniger als 5 g/m². Dies ist gegenüber der Gesamtauftragsmenge von 20-25 g/m² bei den herkömmlichen Lösungen ein bedeutender Vorteil, da das Material hierdurch einfacher zu recyclieren ist.According to a further embodiment of the invention, the basis weights or layer thicknesses specified in claim 5 can be provided. Such a composite results in a water vapor permeability <2 g / m² · d. The total amount of primer and top coat applied is less than 5 g / m². This is a significant advantage compared to the total application quantity of 20-25 g / m² with the conventional solutions, since this makes the material easier to recycle.

Aufgrund der äußerst geringen Wasserdampfdurchlässigkeit des erfindungsgemäßen Verbundstoffes läßt sich dieser zur Verpackung von aroma-, gas- oder feuchtigkeitshaltigen Produkten besonders gut einsetzen.Due to the extremely low water vapor permeability of the composite according to the invention, it can be used particularly well for packaging products containing aromas, gases or moisture.

Nachfolgend wird eine Ausführungsform des erfindungsgemäßen Verbundstoffes rein beispielhaft anhand der beigefügten Figur beschrieben.An embodiment of the composite material according to the invention is described below purely by way of example with reference to the attached figure.

Die Figur zeigt einen teilgeschnittenen Querschnitt durch einen Verbundstoff gemäß der Erfindung.The figure shows a partially sectioned cross section through a composite according to the invention.

Der in der Figur dargestellte Verbundstoff besteht aus einem Basismaterial 10 in Form von herkömmlichem gestrichenen Papier mit einem Flächengewicht von 50 g/m². Auf das Basismaterial 10 ist eine erste Grundierung 12 in Form einer Beschichtung aus Grundierlack mit einem Flächengewicht von 1,8 g/m² aufgebracht.The composite shown in the figure consists of a base material 10 in the form of conventional coated paper with a basis weight of 50 g / m². A first primer 12 in the form of a coating of primer lacquer with a basis weight of 1.8 g / m 2 is applied to the base material 10.

Auf die erste Grundierung 12 ist eine erste Metallisierung 14 mit einer Schichtdicke von 300 Å aufgedampft. Auf diese erste Metallisierung 14 ist eine zweite Grundierung 16 aus einem Grundierlack mit einem Flächengewicht von 1,8 g/m² aufgebracht.A first metallization 14 with a layer thickness of 300 Å is evaporated onto the first primer 12. On this first metallization 14, a second primer 16 is applied from a primer with a basis weight of 1.8 g / m².

Auf die zweite Grundierung 16 ist wiederum eine zweite Metallisierung 18 mit einer Schichtdicke von 300 Å aufgedampft.A second metallization 18 with a layer thickness of 300 Å is in turn evaporated onto the second primer 16.

Schließlich ist auf der zweiten Metallisierung 18 eine Deckschicht 20 in Form von Decklack mit einem Flächengewicht von 1,0 g/m² aufgebracht. Die Wasserdampfdurchlässigkeit dieses Verbundstoffes ist < 2 g/m²·d. Das Material des Grundierlackes und das des Decklackes ist ein Nitrozelluloselack. Die Metallisierung besteht aus Aluminium.Finally, a cover layer 20 in the form of a top coat with a basis weight of 1.0 g / m 2 is applied to the second metallization 18. The water vapor permeability of this composite is <2 g / m² · d. The material of the base coat and that of the top coat is a nitrocellulose paint. The metallization consists of aluminum.
