Mehrschichtige FolienbahnMulti-layer film web
Die Neuerung bezieht sich auf eine mehrschichtige Folienbahn, geeignet zum Verschließen von Behältern aus Kunststoff, Glas oder Metall durch Wärmesiegelung.The innovation relates to a multi-layer film web, suitable for closing containers made of plastic, glass or metal by means of heat sealing.
Es ist bekannt, zum Verschließen derartiger Behälter kaschierte Folien zu verwenden, welche aus einer Papierschicht und einer damit verbundenen Aluminiumfolie und einer Kunststoff-Folie bestehen.It is known to use laminated films for closing such containers, which consists of a paper layer and a associated therewith aluminum foil and a plastic film.
Es hat sich jedoch gezeigt, daß ^ehrschichtfolien, welche keine glänzende, durch die transparente Kunststoffschicht durchscheinende metallische Schicht aufweisen, bei den Käufern der mit solcher Mehrschichtfolie verschlossenen Behälter, beispielsweis« Joghurt-Becher, jedoch auf Ablehnung stoßen, weil diese fälschlicherweise glauben, daß die durch Mehrschicatfolien oder metallische Zwischenschicht minderwertig seien.It has been shown, however, that multi-layer films, which do not contain any have shiny metallic layer translucent through the transparent plastic layer, for buyers of the with such multi-layer film sealed container, for example « Yoghurt cups, however, met with rejection because they mistakenly believe that they were made of multi-layer foils or metallic ones Intermediate layer are inferior.
Der Neuerung liegt die Aufgabe zugrunde, dieses Vorurteil durch einen Kunstgriff zu überwinden und durch Beibehaltung der Möglichkeit einer flüssigkeitsdichten Versiegelung eine billigere Folienbahn anzugeben, <?ie mit den auf dem Markt befindlichen, üblichen Verpackungsmaschinen verarbeitbar ist.The innovation is based on the task of overcoming this prejudice through a trick and by maintaining the possibility to indicate a liquid-tight seal a cheaper film web, <? ie with those on the market, usual packaging machines can be processed.
Diese Aufgabe wird bei einer mehrschichtigen Folienband dadurch gelöst, daß sie von der vorgesehenen Außenseite in Richtung zu der zur Versiegelung vorgesehenen Innenseite aufeinanderfolgend nachstehende Schichten aufweist: erstens, eine Schicht aus Papier mit einem Gewicht von wenigstens 30 Gramm und höchstens 80 Gramm pro Quadratmeter, zweitens eine mit der Papierschieht festverbundene Kunststoffolie, drittens eine Schicht aus Heiß-This task is thereby achieved with a multi-layer film tape solved that they follow one another from the intended outside in the direction of the inside intended for sealing comprises the following layers: first, a layer of paper weighing at least 30 grams and at most 80 grams per square meter, secondly a plastic film firmly attached to the paper, thirdly a layer of hot
Siegellack, wobei eine der auf die Schicht aus Papier folgender Schichten ein Pigment mit sogenanntem Metalleffekt enthält.Sealing wax, one of the layers following the paper layer containing a pigment with a so-called metallic effect.
Weitere Merkmale der Neuerung sind in den Unteransprüchen gekennzeichnet. Further features of the innovation are characterized in the subclaims.
Im Nachstehenden wird die Neuerung in Verbindung mit der ein Ausführungsbeispiel darstellenden Figur beschrieben. In dieser Figur ist in schematisch stark vereinfachter Weise ein streifet artiges Stück einer gemäß der Neuerung ausgeführten mehrschich-l tigen Folienbahn dargestellt. Die oberste Schicht der in der Fiigur dargestellten mehrschichtigen Folienbahn besteht aus Papier: mit einem Gewicht von etwa 50 Gramm pro Quadratmeter. Auf der Unterseite der Papierschicht 2 befindet sich eine Klebstoffschicht 3 aus handelsüblichem Kleber. Es folgt eine durch den Kleber fest mit der Schicht 2 verbundene Kunststoffolie 4, die mit einer Schicht 5 aus Heiß siegellack versehen ist. Die Kunst-·? stoffschicht 4 enthält ein Pigment 6, welches einen sogenannten! Metalleffekt aufweist. 1In the following, the innovation is described in connection with the figure showing an exemplary embodiment. In this Figure is, in a schematically greatly simplified manner, a strip-like piece of a multilayered piece designed according to the innovation term film web shown. The top layer of the multi-layer film web shown in the figure consists of paper: weighing about 50 grams per square meter. There is an adhesive layer on the underside of the paper layer 2 3 made of commercially available glue. This is followed by a plastic film 4 firmly connected to layer 2 by the adhesive, which is provided with a layer 5 of hot sealing lacquer. Art-·? material layer 4 contains a pigment 6, which is a so-called! Has metallic effect. 1
Beim Öffnen eines mittels Mehrschichtfolie verschlossenen Behsd ters wird die metallisch schimmernde Unterseite sichtbar umd dadurch der gewohnte Anblick erzielt.When opening a container closed by means of a multilayer film ters, the metallic shimmering underside becomes visible and thereby the familiar sight achieved.
Es ist auch möglich, die Pigmente in der Klebstoffschicht 3 od(| der Schicht 5 des Heißsiegellackes anzuordnen.It is also possible to use the pigments in the adhesive layer 3 od (| the layer 5 of the heat seal lacquer to be arranged.
Als Material für die Kunststoff-Folie haben sich Polypropylen, Polyäthylen und Polyamid bewährt. Die Wahl des Kunststoffmate- | rials hängt von den an die Mehrschichtfolie gestellten Anfor- I derungen ab. IPolypropylene, polyethylene and polyamide have proven themselves as materials for the plastic film. The choice of plastic material | rials depends on the requirements placed on the multilayer film changes. I.
Bei der Verarbeitung wird die Mehrschichtfolie zum Verschließen; von Gefäßen, beispielsweise zum Verschließen von Joghurt-BeeheilDuring processing, the multilayer film is used for sealing; of vessels, for example for closing yoghurt beehives
verwendet, wobei die Heißsiegel-Lackschicht auf den zugeordneten Rand des zu verschließenden Bahälters in bekannter Weise aufge-| bracht wird. 1used, with the heat-seal varnish layer on the associated The edge of the container to be closed is opened in a known manner is brought. 1
Aliv/eichend von dem vorstehend beschriebenen Ausführungsbeispiel kann auch der Kunststoff ohne Verwendung eines Klebers bzw. eine Klebstoffschicht mit der Papierschicht fest verbunden sein. In diesem Pail wird bei der Herstellung der warme flüssige Kunststoff direkt auf das laufende Papierband extrudiert. Hierdurch wird erreicht, daß Kunststoff in die Poren der Papierschicht eindringt und damit eine feste Verbindung zwischen Papierschicht 2 und Kunststoff-Folie 4 hergestellt wird.Aliv / calibrated from the embodiment described above the plastic can also be firmly connected to the paper layer without using an adhesive or an adhesive layer. In This pail is used in the manufacture of the warm liquid plastic extruded directly onto the running paper tape. This ensures that plastic gets into the pores of the paper layer penetrates and thus a firm connection between the paper layer 2 and the plastic film 4 is established.
