Abstract

The printed sheet material provided with a thermoplastic primer and printing is coated with a lacquer of appropriate composition in such a way that a part of the hardener - either present in the lacquer or applied separately - migrates into the primer and the printing medium and leads to their reticulation.

Description

Die Erfindung richtet sich auf ein bedrucktes, bahnförmiges Material, insbesondere eine Abdeckung für einen Behälter für Milchprodukte, bestehend aus einer Folie aus Kunststoff, Papier oder Metall auf der Sichtseite.The invention is directed to a printed, web-like material, in particular a cover for a container for dairy products made of plastic, paper or metal foil on the visible side.

Die Herstellung des Aufdrucks auf derartigen Abdeckungen erfolgt herkömmlicherweise im Flexo- oder Tiefdruck-Verfahren. Diese Druckverfahren sind, wenn es um die Herstellung von Kleinaufträgen geht, äußerst unrationell. Muß beispielsweise für Messen oder eine interne Produktvorstellung die Qualität der Verschlußfolie bzw. Abdeckungen mit dem später auf dem Markt befindlichen Endprodukt identisch sein, so muß in teuere Druckzylinder und Maschinenkosten investiert werden. Alternativ müssen mit anderen Andruckverfahren Muster hergestellt werden, welche dann aber mit dem auf einer Druckmaschine produzierten Original nicht vergleichbar sind. Werden nach der Vorstellung eines solchen Produkts nochmals Änderungen erforderlich und wurden bereits Druckzylinder produziert, so müssen neue, geänderte Druckzylinder erstellt werden, was ebenfalls sehr kostenintensiv ist.The printing on such covers is conventionally carried out in flexographic or gravure printing. This printing process are extremely inefficient when it comes to producing small orders. For example, for trade fairs or an internal product presentation the quality of the sealing film or covers with that later on end product on the market must be identical, so expensive Printing cylinders and machine costs are invested. Alternatively, must patterns can be produced with other pressure processes, which then but not comparable to the original produced on a printing press are. Will be after the launch of such a product further changes required and printing cylinders have already been produced, so new, modified printing cylinders have to be created, which also is very expensive.

In diesem Zusammenhang ist es aus DE 299 03 364 U1 bekannt, den durch eine Digitaldruckmaschine hergestellten Aufdruck zwischen zwei Schichten anzuordnen, wobei eine der Schichten eine Niedertemperatur-Heißsiegellackschicht ist. Durch die Verwendung einer Digitaldruckmaschine ist es möglich, den an sich konkurrierenden Anforderungen gerecht zu werden, daß derartige Abdeckungen üblicherweise bei Temperaturen zwischen 180°C und 250°C gesiegelt werden, wohingegen die derzeit erhältlichen Druckfarben für den Digitaldruck nur bis 100°C stabil sind und die normalerweise eingesetzten Heißsiegellacke erst bei 160°C richtig zu siegeln beginnen. Durch die vorbekannte Einbettung der digitalen Druckfarben in zwei Schichten werden die Druckfarben geschützt und die Verwendung einer Niedertemperatur-Heißsiegellackschicht verhindert eine Beschädigung derselben aufgrund höherer Temperaturen.In this context, it is known from DE 299 03 364 U1, which by a digital printing press produced between two layers to be arranged, one of the layers being a low-temperature heat seal lacquer layer is. By using a digital press it is possible to meet the competing requirements be that such covers usually at temperatures between 180 ° C and 250 ° C can be sealed, whereas the currently available Printing inks for digital printing are only stable up to 100 ° C and that Only properly seal heat sealing lacquers normally used at 160 ° C kick off. Through the previously known embedding of digital printing inks the printing inks are protected in two layers and the use a low-temperature heat seal lacquer layer prevents damage the same due to higher temperatures.

Auch bei anderen Anwendungen kann die mangelnde Temperaturbeständigkeit der Druckfarben zu Problemen führen, z.B. wenn Dekorfolien mittels eines Schmelzklebers auf Spanplatten aufgezogen werden sollen, wie dies beispielsweise im Möbelbereich der Fall ist.The lack of temperature resistance can also occur in other applications the printing inks lead to problems, e.g. when using decorative foils a hot melt adhesive to be mounted on chipboard, such as this is the case, for example, in the furniture sector.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, unter Wahrung der Vorteile der vorbekannten Anordnung ein bedrucktes Material, insbesondere eine Abdeckung, zu schaffen, die mit beliebigen Heißsiegellacken ausgestattet und verarbeitet werden kann, bzw. generell eine bedruckte Materialbahn temperaturstabil auszugestalten.Proceeding from this, the invention is based on the object, while maintaining the advantages of the known arrangement a printed material, in particular to create a cover with any heat seal lacquer can be equipped and processed, or generally a printed one Design material web temperature stable.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein zur Aufbringung des Drucks erforderlicher thermoplastischer Primer und die Druckfarbe selbst mit einem Lack gleicher oder ähnlicher Zusammensetzung derart überlackiert sind, daß ein Teil des im Überlack vorhandenen oder gesondert auf- bzw. eingebrachten Härters in die Druckfarbe bzw. in den thermoplastischen Primer migriert und zu einer Vernetzung führt.This object is achieved in that an application the required thermoplastic primer and the printing ink even with a varnish of the same or similar composition are overcoated that part of the existing or separate in the overcoat applied or introduced hardener in the printing ink or in the thermoplastic primer migrates and leads to crosslinking.

Auf diese Weise wird erreicht, daß ein an sich thermoplastisches System mit einem Erweichungspunkt von ca. 90°C in ein hitzebeständiges System mit einer Hitzebeständigkeit von ca. 280°C übergeht. Die entsprechende Reaktion ist zeitabhängig und bei Raumtemperatur nach ca. 4 Tagen abgeschlossen. Aufgrund der so erzielten Hitzebeständigkeit ist es möglich, mit beliebigen herkömmlichen Heißsiegellacken zu arbeiten, um mittels einer solchen Abdeckung einen Behälter zu verschließen oder eine Weiterverarbeitung mittels eines Schmelzklebers zu realisieren.In this way it is achieved that an inherently thermoplastic system with a softening point of approx. 90 ° C in a heat-resistant system with a heat resistance of approx. 280 ° C. The corresponding The reaction is time-dependent and takes about 4 days at room temperature. Due to the heat resistance achieved in this way, it is possible to use any conventional heat seal lacquer to work by means of a such a cover to close a container or further processing using a hot melt adhesive.

Vorzugsweise ist vorgesehen, daß der thermoplastische Primer bzw. der Überlack eine Ethylen-Acrylat-Copolymer-Dispersion oder eine Abmischung derselben mit Polyester, PVAC oder Polyamid ist.It is preferably provided that the thermoplastic primer or Top coat an ethylene-acrylate copolymer dispersion or a blend the same with polyester, PVAC or polyamide.

Als Härter kommt günstigerweise ein polyfunktionelles Aziridin in Betracht.A polyfunctional aziridine is advantageously considered as the hardener.

Das erfindungsgemäß erzeugte, vernetzte Produkt ist insbesondere ein Polykondensat.The crosslinked product produced according to the invention is in particular a polycondensate.

Die erfindungsgemäße Ausgestaltung eignet sich besonders in Verbindung mit einem Digital-Druck, der ausgehend von einem flüssigen, thermoplastischen Toner unter Übertragung auf ein Zwischenmedium durch elektrostatisch erzeugten Bildaufbau hergestellt ist. Dies bedeutet, daß kein direkter Kontakt mit dem zu bedruckenden Material besteht, weshalb auch Aluminiumfolie bedruckt werden kann.The configuration according to the invention is particularly suitable in connection with a digital print based on a liquid, thermoplastic Toner transferred to an intermediate medium by electrostatic generated image structure is produced. This means that no direct There is contact with the material to be printed, which is why aluminum foil can be printed.

Ein solches Druckverfahren wird auch als Indigo-Verfahren bezeichnet. Dabei enthalten die eingesetzten Druckfarben neben den Farbpigmenten zusätzlich Ladungsmoleküle, die im elektrischen Feld ausgerichtet werden können. Zum Drucken wird eine lichtempfindliche Beschichtung elektrostatisch auf etwa 800 V aufgeladen und anschließend laserbelichtet. An den belichteten Punkten sinkt die elektrische Ladung auf ca. 100 V ab. Dort lagern sich bei vollflächiger Einfärbung der Beschichtung die Farbpartikel der Druckfarbe an. Die nicht belichteten Stellen nehmen, da die Ladung zu hoch ist, keine Farbe an. Das so entstandene Druckbild wird auf ein Zwischenmedium, ein sogenanntes Blanket, übertragen. Die Blanket-Temperatur beträgt ca. 130°C. Dort verdampft das Trägeröl, welches in der Farbe enthalten ist, und das Gesamtdruckbild polymerisiert zu einer thermoplastischen Schicht. Diese Schicht ist auf Papier ohne Primer übertragbar, bei Aluminiumfolien oder dergleichen ist die Übertragung nur unter Verwendung eines Primers möglich, mit dem das bahnförmige Material ausgerüstet werden muß. Der Erweichungspunkt des Primers muß dabei deutlich unter der Blanket-Temperatur von 130°C liegen. Eine weitere wichtige Eigenschaft des Primers ist ein hoher, sogenannter "hot tack", der sowohl zum bedruckenden Material als auch zur Druckfarbenschicht eine ausreichende Adhäsion mit sich bringt, um eine einwandfreie Übertragung zu gewährleisten.Such a printing process is also referred to as an indigo process. The printing inks used contain the color pigments additionally charge molecules that are aligned in the electric field can. A photosensitive coating becomes electrostatic for printing charged to about 800 V and then laser exposed. To the exposed points, the electrical charge drops to approx. 100 V. There the color particles are stored when the coating is colored all over the ink. The unexposed areas increase as the charge increases is high, no color. The resulting print image is placed on an intermediate medium, a so-called blanket. The blanket temperature is approx. 130 ° C. There the carrier oil evaporates, which is in color is contained, and the total printed image polymerized to a thermoplastic Layer. This layer is transferable to paper without primer, at Aluminum foils or the like is only used using the transfer possible with a primer with which the sheet-like material is equipped must become. The softening point of the primer must be clear below the blanket temperature of 130 ° C. Another important property The primer is a high, so-called "hot tack", which both sufficient for the printing material and the ink layer Adhesion brings to a perfect transfer guarantee.

Alternativ kann das Bedrucken auch mit flüssiger Tinte und einem Druckkopf oder mittels eines festen, thermoplastischen Toners erfolgen.Alternatively, printing can also be done with liquid ink and a printhead or by means of a solid, thermoplastic toner.

Gemäß einem bevorzugten Ausführungsbeispiel weist eine erfindungsgemäße Abdeckung folgenden Aufbau auf:

  • Basis ist eine Aluminiumfolie mit einer Dicke < 10 µm;
  • ein einkomponentiger Primer mit 0,3 bis 0,6 g/m2 als Ethylen-Acrylat-Copolymer-Dispersion ist vorgesehen;
  • ein Digitaldruck ist gemäß dem Indigo-Verfahren hergestellt;
  • auf die Oberseite ist ein Überlack im Zwei-Komponenten-System mit 0,8 bis 1,5 g/m2 in Form einer Ethylen-Acrylat-Copolymer-Dispersion aufgebracht.
According to a preferred embodiment, a cover according to the invention has the following structure:
  • The basis is an aluminum foil with a thickness of <10 µm;
  • a one-component primer with 0.3 to 0.6 g / m 2 as an ethylene-acrylate copolymer dispersion is provided;
  • digital printing is made according to the indigo process;
  • a top coat in a two-component system with 0.8 to 1.5 g / m 2 in the form of an ethylene-acrylate copolymer dispersion is applied.

Die vorgenannten Schichten besitzen jeweils endständige OH-Gruppen, wobei der Vernetzungsgrad durch die Beeinflussung der OH-Gruppen einstellbar ist. Die eingesetzte Druckfarbe ist thermoplastisch, wird aber aus der Lösung und nicht aus der Schmelze aufgetragen. Aufgrund der erfindungsgemäß erzielten Polykondensations-Vernetzung wird erreicht, daß bei einem Arbeiten mit einem herkömmlichen Siegelwerkzeug bei der üblichen erhöhten Siegeltemperatur das Druckbild nicht zerstört wird.The aforementioned layers each have terminal OH groups, the degree of crosslinking being adjustable by influencing the OH groups is. The printing ink used is thermoplastic, but becomes out the solution and not from the melt. Because of the invention achieved polycondensation crosslinking is achieved in that when working with a conventional sealing tool in the usual increased sealing temperature the printed image is not destroyed.
