Abstract

The invention relates to a composite film (multilayer film), in particular a metallised, gas- and water vapour-impermeable composite film printed by counterprinting for packaging, in particular foodstuffs packaging. The feature of the invention is the sequence of the composite of a transparent polyester film printed on the composite side with printing inks based on soluble metal-complex dyes, an aluminium film vapour-deposited thereon in a high vacuum, and a polyolefin film laminated onto the aluminium film by means of an adhesive. The complex lacquering of the packaging material which was conventional hitherto thus becomes superfluous.

Description

Anwendungsgebiet der ErfindungField of application of the invention

Die Erfindung betrifft einen Verbundwerkstoff, insbesondere einen metallisierten, gas- und wasserdampfdichten, gekontert bedruckten Verbundwerkstoff für Verpackungen.The invention relates to a composite material, in particular a metallized, gas and water vapor tight, countered printed composite material for packaging.

Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions

Bekannte Verbundwerkstoffe für Verpackungen bestehen aus zwei, gegebenenfalls mit Klebstoff miteinander verbundenen Olefin­ polymerfolien, wobei wenigstens eine der Folien mit einem als Abschirmung gegenüber Gasen und Wasserdämpfen dienenden Lack beschichtet und auf jeder Seite metallisiert ist, die mit der anderen Folie in Kontakt steht (DE-OS 32 43 272). Sollen Ver­ bundwerkstoffe gekontert bedruckt werden, so ist es üblich, insbesondere beim Flexo- und/oder Tiefdruck, Druckfarben zu verwenden, welche pigmentierte Farbmittel enthalten. Pigmen­ tierte Farbmittel enthaltende Druckfarben ergeben im getrock­ neten Zustand einen Druckfarbenfilm mit unebener Oberfläche mit einer Rauhtiefe 2 µm, so daß die anschließende Metalli­ sierung allein nicht ausreicht, eine gas- und wasserdampf­ dichte Folie zu schaffen.Known composite materials for packaging consist of two, optionally olefin bonded together with adhesive polymer films, wherein at least one of the films with a Shielding against gases and water vapor used lacquer coated and metallized on each side with the other film is in contact (DE-OS 32 43 272). Should Ver counter materials are printed counter-clockwise, so it is common especially in flexo and / or gravure printing, printing inks too use which contain pigmented colorants. Pigmen inks containing colorants result in dried form an ink film with an uneven surface with a roughness depth of 2 µm, so that the subsequent metal sation alone is not sufficient, a gas and water vapor to create dense film.

Aus diesem Grunde wird zusätzlich eine Lackschicht aufgetragen, welche zwar diesen Mangel beseitigt, jedoch den Herstellungs­ aufwand erheblich erhöht.For this reason, an additional layer of lacquer is applied, which eliminates this defect, but the manufacturing expenses increased significantly.

Es ist weiterhin bekannt, anstelle der pigmentierte Farbmittel enthaltenden Druckfarben für das Bedrucken von Metallfolien, insbesondere Aluminiumfolien, lösliche, organische Metall­ komplexfarbstoffe enthaltende Farbmittel zu verwenden. Die daraus resultierenden trockenen Druckfarbenfilme weisen eine ebene Oberfläche mit einer Rauhtiefe von annähernd "Q" auf. It is also known to use soluble, organic metal complex dyes, instead of the printing inks containing pigmented colorants, for printing metal foils, in particular aluminum foils. The resulting dry printing ink films have a flat surface with a roughness of approximately " Q ".

Derartige Druckfarben für das Bedrucken von Aluminiumfolie haben bisher keine Anwendung für die Direktmetallisierung auf den Druckfarbenfilm zur Herstellung gas- und wasserdampf­ dichter Kunststoffolien gefunden, da die Farbhaftung solcher Farbfilme durch den Einfluß der Metallisierung nachhaltig beeinflußt wird.Such printing inks for printing on aluminum foil have so far had no application for direct metallization the ink film for the production of gas and water vapor dense plastic films found because the color adhesion of such Color films sustained by the influence of metallization being affected.

Ziel der ErfindungAim of the invention

Die Erfindung hat das Ziel, den Herstellungsaufwand des Ver­ bundwerkstoffes bei gleichbleibender Gebrauchseigenschaften wie Gas- und Wasserdampfdichte sowie guter mechanischer und physikalischer Eigenschaften, wesentlich zu reduzieren.The invention has the aim of reducing the manufacturing effort of the Ver material with the same properties such as gas and water vapor density as well as good mechanical and physical properties, significantly reduce.

Darlegung des Wesens der ErfindungState the nature of the invention

Der Erfindung liegt darum die Aufgabe zugrunde, den Verbund­ werkstoff in seinem strukturellen Aufbau und seiner Druck­ farbenzusammensetzung zu verbessern.The invention is therefore based on the object, the composite material in its structural structure and its pressure improve color composition.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß auf eine Lackierung des Verbundwerkstoffes verzichtet werden kann, wenn dieser aus einem Verbund von einer transparenten, auf der Verbundseite mit Druckfarben auf der Basis löslicher Metall­ komplexfarbstoffe bedruckten Polyesterfolie, von einem darauf im Hochvakuum aufgedampften Aluminiumfilm und von einer wiederum auf den Aluminiumfilm mittels eines Klebstoffes kaschierten Polyolefinfolie besteht.According to the invention the object is achieved in that on a Painting of the composite material can be dispensed with, if this consists of a composite of a transparent, on the Composite side with printing inks based on soluble metal complex dyes printed polyester film, from one on it Aluminum film evaporated in a high vacuum and from one again laminated to the aluminum film using an adhesive There is polyolefin film.

Es wurde gefunden, daß bei einem derartigen Verbund auf die bisher übliche und notwendige Lackierung zur Erzielung der Gas- und Wasserdampfdichte für Lebensmittelverpackungen verzichtet werden kann. Weitere Vorteile sind gleichbleibende mechanische und physikalische Gebrauchseigenschaften sowie ein wesentlich geringerer Herstellungsaufwand einschließlich verringerter Energie- und Materialeinsatz.It was found that in such a composite on the Previously usual and necessary painting to achieve the gas and water vapor density for food packaging can be. Other advantages are constant mechanical and physical usage properties as well as an essential lower manufacturing costs including reduced Use of energy and materials.
