Description
BeschreibungDescription
Die Erfindung betrifft eine homogene, dickenvariable Sperrschicht die mittels des Druckverfahrens auf Bogen- und Rollenmaterial aufgebracht ist.The invention relates to a homogeneous, variable-thickness barrier layer which is applied to sheet and roll material by means of the printing process.
Eine Sperrschicht für Fettbeständigkeit ist bekannt. Diese besteht aus Wachs oder Folie. Wenn es sich um Wachs handelt, dann ist das Aufbringen zeit- und kostenaufwendig, da die Produktionsgeschwindigkeit begrenzt ist. Ist es Folie, dann muss das außerhalb der Druckmaschine gemacht werden. Die Schicht wird auf die Rückseite von Bogen- oder Rollenmaterial aufgebracht. Beide Verfahren sind daher kosten- und zeitaufwendig und nicht dickenvariabel. Im Ergebnis ist dies noch nicht optimal.A barrier layer for grease resistance is well known. This consists of wax or foil. If it is wax, then applying it is time-consuming and expensive, as the production speed is limited. If it is foil, then this has to be done outside the printing machine. The layer is applied to the back of sheet or roll material. Both processes are therefore costly and time-consuming and the thickness cannot be varied. The result is not yet optimal.
Die Erfindung hat den Vorteil, daß die Sperrschicht mit Hilfe des Tief- oder Flexodruckes in der Druckmaschine in einem Arbeitsgang aufbringbar ist. Es handelt sich um eine Schicht, die entsprechend des Materials in der Dicke variieren kann, ohne die Homogenität zu verlieren. Dabei können auf der Vorderseite — bei der Herstellung in einem Arbeitsgang — z. B. mehrfarbige Drucke erfolgen. Auch ist die Geschwindigkeit der Herstellung der Sperrschicht mit Hilfe des erwähnten Druckverfahren höher als bei den bisher bekannten Verfahren. Die Sperrschicht ist wärme- oder kältespeichernd und zugelassen für den Kontakt mit Lebensmitteln.The invention has the advantage that the barrier layer can be applied in a single operation using gravure or flexographic printing in the printing machine. It is a layer that can vary in thickness depending on the material without losing its homogeneity. In this case, multi-colored prints can be made on the front side - if it is produced in a single operation. The speed of producing the barrier layer using the printing process mentioned is also higher than with previously known processes. The barrier layer stores heat or cold and is approved for contact with food.
Die mittels des Druckverfahrens aufgebrachte Sperrschicht ist zudem siegelfähig.The barrier layer applied using the printing process is also sealable.
Das Aufbringen der Sperrschicht 4 (Lösung) erfolgt bei gleicher Druckgeschwindigkeit mit einem Tiefdruckzylinder 3. Dieser Tiefdruckzylinder 3 hat eine endlose Anordnung über Umfang und Breite von Näpfchen. Der Zylinder 3 taucht in die Sperrschicht 4 (Lösung) und die Näpfchen füllen sich mit der Sperrschicht 4 (Lösung) bei jeder Umdrehung des Zylinders 3. Von dem Zylinder 3 wird die überflüssige Sperrschicht 4 (Lösung) mit einem Rakel 5 abgerakelt.The barrier layer 4 (solution) is applied at the same printing speed using a gravure cylinder 3. This gravure cylinder 3 has an endless arrangement of cells across the circumference and width. The cylinder 3 dips into the barrier layer 4 (solution) and the cells fill up with the barrier layer 4 (solution) with each rotation of the cylinder 3. The excess barrier layer 4 (solution) is scraped off the cylinder 3 using a doctor blade 5.
Das Material 1 wird im Kontakt, der über einen Presseur hergestellt wird, über den Zylinder 3 geführt. Dabei wird die Sperrschicht 4 in den Näpfchen, die hier zunächst als Lösung vorhanden ist, auf das Material 1 übertragen. Die Materialware wird anschließend mit Heißluft oder in Kontakt mit einer in dem Druckwerke befindlichen heißen Trommel 8 getrocknet. Damit entweicht das Lösemittel. Man erhält als Endprodukt ein fertiges Material 1 mit Beschichtung auf der Rückseite und Aufdruck auf der Vorderseite. Was für den Tiefdruck gesagt ist, gilt sinngemäß für den Flexodruck, wobei hier der gravierte Tiefdruckzylinder durch eine Rasterwalze ersetzt wird.The material 1 is guided over the cylinder 3 in contact, which is made by an impression roller. The barrier layer 4 in the cells, which is initially present as a solution, is transferred to the material 1. The material is then dried with hot air or in contact with a hot drum 8 in the printing unit. This causes the solvent to escape. The end product is a finished material 1 with a coating on the back and a print on the front. What has been said for gravure printing applies analogously to flexographic printing, whereby the engraved gravure cylinder is replaced by an anilox roller.
Das beschichtete Material 1 ist Rollenmaterial und kann Papier, Karton oder Folie sein, wobei ein weiterer Vorteil darin besteht, daß auch kleine Mengen kostengünstig beschichtet werden können.The coated material 1 is roll material and can be paper, cardboard or film, with a further advantage being that even small quantities can be coated cost-effectively.
