Abstract

Method of manufacturing of a multilayer plastic film which has a backing layer an adhesive layer, and a cover layer, which by means of a tool or object inducing pressure exposes the adhesive arranged underneath the cover layer. The three layers, i.e., backing, adhesive and cover layer are coextruded in one step, wherein the layers have preferably the following thicknesses: backing from 20 microns to 100 microns, adhesive from 10 microns to 100 microns, plastic cover layer from 2 microns to 20 microns. The cover layer consists of a brittle extrudable thermoplast, preferably a brittle-hardening polyethylene or polystyrene.

Description

Die Erfindung betrifft eine mehrlagige Kunststoff-Folie, die eine Traghaut und eine darauf aufgetragene Kleb­ schicht aufweist.The invention relates to a multilayer plastic film, which has a skin and a glue applied to it has layer.

Derartige Kunststoff-Folien sind bekannt. Sie werden üblicherweise mit einem Haftkleber versehen und können beispielsweise als Klebestreifen verwendet werden.Such plastic films are known. you will be usually provided with a pressure sensitive adhesive and can can be used for example as adhesive strips.

Weiterhin ist bekannt, Klebestreifen, Plaketten und der­ gleichen, die eine Klebschicht aufweisen, mit einer nicht-haftenden Folie zu überziehen, die vor dem Ver­ kleben abgezogen wird. Gegenüber diesen bekannten Folien stellt sich die Aufgabe, eine mehrlagige Kunststoff-Folie anzugeben, die in einfacher Weise herstellbar und in vielfacher Weise verwendet werden kann, wobei ebenfalls eine geschützte Klebschicht vorliegt, die jedoch in ko­ stengünstigerer Weise geschützt und zum Verkleben frei­ gegeben werden kann, als die eingangs genannten, mit einer nicht-haftenden Abziehfolie ausgestatteten bekann­ ten Produkte.It is also known to have adhesive strips, badges and the like same, which have an adhesive layer with a to cover non-adhesive film, which before the Ver stick is peeled off. Compared to these known films the task is to create a multilayer plastic film specify which is easy to manufacture and in can be used in many ways, also a protected adhesive layer is present, but in ko most cheaply protected and free for gluing can be given as the above, with equipped with a non-adhesive release film products.

Die Aufgabe gemäß Erfindung wird gelöst durch eine mehr­ lagige Kunststoff-Folie, die eine Traghaut und eine dar­ auf aufgetragene Klebeschicht aufweist, und die dadurch gekennzeichnet ist, daß die auf die Traghaut aufgetragene Klebschicht nach außen von einer spröden Kunststoff-Deck­ schicht überzogen ist, die mit Hilfe eines die Deck­ schicht aufbrechenden Werkzeuges oder Gegenstandes auf wenigstens einem Teil ihrer Fläche aufsprengbar ist, damit die unterhalb der Deckschicht liegende Klebschicht freigelegt wird oder der Klebstoff austreten kann, wobei die Traghaut mit den beiden weiteren Schichten coextru­ diert ist.The object according to the invention is achieved by more ply plastic film that represents a skin and a on the applied adhesive layer, and thereby is characterized in that the applied to the skin Adhesive layer to the outside of a brittle plastic deck  layer that is covered with the help of a deck layer of breaking tool or object at least part of its surface can be blown open, thus the adhesive layer below the top layer is exposed or the adhesive can escape, whereby the skin with the two other coextru layers is dated.

Unter der "Traghaut" werden verschiedene extrudierbare Thermoplasten verstanden, wie diese an sich im Stand der Technik bekannt sind. Es kann sich allgemein um Polyole­ fine oder Olefin-Kopolymere mit verschiedenen mechani­ schen und chemischen Eigenschaften handeln. Wesentlich ist, daß bei Anwendung des Werkzeuges die Traghaut nicht zerstört wird, d. h., daß sie wesentlich elastischer ist als die spröde Deckschicht. Unter "Werkzeug" werden ge­ riffelte, angespitzte oder gekantete Vorrichtungen ver­ standen, die eine Scher- oder Druckspannung erzeugen und die die Deckschicht zum Zerreißen oder Aufsprengen brin­ gen. Es kann sich aber auch um "Gegenstände" handeln, wobei hierunter insbesondere die Auflage selbst verstan­ den wird, auf der die mehrlagige Folie verklebt wird. Gedacht ist beispielsweise an flanschartige Ränder von Kunststoff-Bechern, die bereits eine entsprechende Rif­ felung oder Waffelung tragen, so daß die aufgelegte mehr­ lagige Folie dort so unter Spannung gesetzt wird, daß die spröde Deckschicht aufreißt.Various extrudable materials can be found under the "support skin" Thermoplastics understood how these per se in the state of the Technology are known. It can generally be polyols fine or olefin copolymers with various mechani act and chemical properties. Essential is that when using the tool, the skin is not is destroyed, d. that is, it is much more elastic than the brittle top layer. Under "Tools" are ge corrugated, pointed or edged devices stood that generate a shear or compressive stress and that cause the top layer to tear or burst open gen. But it can also be "objects" this includes in particular the edition itself the one on which the multilayer film is glued. For example, flange-like edges of Plastic cups that already have a corresponding rif Wrapping or waffles, so that the hang up more layered film is put under tension so that the brittle top layer tears open.

Die spröde Deckschicht wird insbesondere aus einem sprö­ den Polyethylen oder Polystyrol bestehen. Als Klebschicht eignen sich haftende Selbstklebemassen oder Schmelzkle­ ber, wie diese an sich bekannt sind. Selbstklebemassen oder Haftklebstoffe sind elastische und dauernd kleb­ fähige Massen mit großen Adhäsions- und kleinen Kohäsi­ onskräften, die schon unter geringem Druck bei Raumtempe­ ratur auf den verschiedenen Oberflächen sofort haften. Sie werden beispielsweise für Klebefolien und -bänder, Selbstklebeetiketten und dergleichen verwendet. Es han­ delt sich im allgemeinen um hoch-viskose Lösungen oder Dispersionen von Kautschuk, Polyacrylaten, Polyvinyl­ ethern bzw. Polyvinylisobutylen, die auf die Traghaut aufgetragen werden. Schmelzkleber sind beispielsweise Polyacrylate, Ethylvinylacetat-Polymere oder Polyester. Die vorgenannten Klebemassen und Schmelzkleber werden anhand ihrer Verträglichkeit mit dem Material der Trag­ haut und ihrer Koextrusionsfähigkeit vom Fachmann be­ stimmt. Derartige Klebemassen und Haftklebstoffe können auch so eingestellt sein, daß sie ein Abziehen und Wie­ derankleben eines Objektes erlauben. Dies gilt auch für die im folgenden genannten Ausführungsformen und Ausge­ staltungen der Erfindung mutatis mutandis.The brittle top layer is in particular made of a brittle consist of polyethylene or polystyrene. As an adhesive layer Adhesive self-adhesive or hot melt adhesive are suitable about how they are known per se. Self-adhesive or pressure sensitive adhesives are elastic and permanently adhesive capable masses with large adhesion and small cohesi forces that are already under low pressure at room temperature adhere immediately to the various surfaces. They are used, for example, for adhesive films and tapes,  Self-adhesive labels and the like are used. It han is generally a highly viscous solution or Dispersions of rubber, polyacrylates, polyvinyl ethers or polyvinyl isobutylene on the skin be applied. Hot melt adhesives are for example Polyacrylates, ethyl vinyl acetate polymers or polyesters. The aforementioned adhesives and hot melt adhesives are based on their compatibility with the material of the support skin and its ability to coextrude from the expert Right. Such adhesives and pressure sensitive adhesives can also be set to pull off and how allow the sticking of an object. This also applies to the embodiments and Ausge mentioned below Events of the invention mutatis mutandis.

Im Rahmen der Erfindung läßt sich ein Verfahren zum Verschließen von Öffnungen, z. B. Einfüllöffnungen von Kunststoff-Bechern und dergleichen, angeben, wobei diese Öffnungen von einem flanschartigen Rand umgeben sind. Die Verfahrensschritte sind:Within the scope of the invention, a method for Closing openings, e.g. B. filling openings of Specify plastic cups and the like, these Openings are surrounded by a flange-like edge. The Process steps are:

  • - durch Koextrusion wird eine mehrlagige Kunststoff-Folie hergestellt, bei der auf einer Traghaut eine Klebe­ schicht aufgetragen wird, die während der Koextrusion noch von einer spröden Kunststoff-Deckschicht überzogen wird;- by coextrusion, a multilayer plastic film made with an adhesive on a base layer is applied during coextrusion still covered with a brittle plastic top layer becomes;
  • - nach Auflegen der Folie auf den Rand der Öffnung wird diese mit Hilfe eines Werkzeuges dort angepreßt, so daß die spröde Kunststoff-Deckschicht oberhalb des Randes aufgesprengt wird und der Klebstoff austritt und eine Klebverbindung zwischen Öffnungsrand und Traghaut herstellt.- After placing the film on the edge of the opening pressed them there with the help of a tool, so that the brittle plastic top layer above the edge is blown open and the adhesive escapes and a Adhesive connection between the edge of the opening and the skin manufactures.

Ein entsprechender Randabschluß kann dann durch ein Stanz- oder Schneidwerkzeug hergestellt werden. Wie ein­ gangs schon gesagt, kann das Anpressen und Aufsprengen der Deckschicht auch dadurch erleichtert werden, daß der Rand um die Einfüllöffnung mit Erhebungen, Waffelungen und ähnlichen Strukturen versehen ist, die die Deck­ schicht zerstören und einen durchgehenden Klebering er­ geben.A corresponding border can then be closed by a Stamping or cutting tool can be produced. Like a As already mentioned, it can be pressed and blown open the top layer can also be facilitated in that the Edge around the filling opening with elevations, waffles  and similar structures that cover the deck destroy the layer and a continuous adhesive ring give.

Wird eine Folie verwendet, die mit einem Schmelzkleber ausgestattet ist, so wird dieser während oder nach dem Anpressen der Folie erwärmt. Hierzu werden entsprechend ausgestattete Werkzeuge, beispielsweise Hochfrequenz- Elektroden, herangeführt.If a film is used with a hot melt adhesive is equipped, this will be during or after Pressing the film warmed. This will be done accordingly equipped tools, for example high-frequency Electrodes, introduced.

Schließlich können im Rahmen der Erfindung auch mehrla­ gige flächige Körper hergestellt werden unter Verwendung der Kunststoff-Folie. Hierbei wird die mehrlagige Kunst­ stoff-Folie nach der Koextrusion mit Papier, Pappe, Me­ tallfolie oder anderen flächigen Materialien verklebt, indem mit Hilfe eines Werkzeuges oder Gegenstandes die Deckschicht aufgebrochen und aufgesprengt wird, so daß der Klebstoff freigelegt wird.Finally, in the context of the invention, more than one Flat sheets are produced using the plastic film. This is the multi-layer art fabric film after coextrusion with paper, cardboard, me glued to foil or other flat materials, by using a tool or object Top layer is broken open and blown open so that the adhesive is exposed.

Es ist auch möglich, einen mehrlagigen, flächigen Körper dadurch herzustellen, daß er aus zwei im Bereich der spröden Kunststoff-Deckschicht aufeinandergelegten, vor­ zugsweise gleichen Kunststoff-Folien besteht, die nach dem Aufsprengen der Deckschicht untereinander verklebt sind.It is also possible to have a multilayer, flat body in that it consists of two in the area of brittle plastic top layer laid on top of each other preferably there is the same plastic film that after glued to each other when the top layer bursts open are.

Vorzugsweise wird man für die mehrlagige Kunststoff-Folie folgende Abmessungen der einzelnen Schichten wählen:One is preferred for the multilayer plastic film select the following dimensions of the individual layers:

Traghaut:von 20 µm bis 100 µm Klebschicht:von 10 µm bis 100 µm Kunststoff-Deckschicht:von  2 µm bis  20 µmBase skin: from 20 µm to 100 µm Adhesive layer: from 10 µm to 100 µm Plastic top layer: from 2 µm to 20 µm

Die vorgenannten Werte sind allerdings nicht einschrän­ kend zu verstehen. Insbesondere die Traghaut kann je nach Steifigkeit und Dicke davon wesentlich abweichende Maße aufweisen. However, the above values are not restricted understandable. In particular, the skin can vary Stiffness and thickness differ significantly from this exhibit.  

Ausdrücklich sei auch angegeben, daß die Traghaut wie­ derum nur als Teil einer Trägerschicht dienen kann, wobei z. B. auf der der Klebschicht gegenüberliegenden Seite der Traghaut andere Materialien aufkaschiert sind, wie Metallfolien, weitere Kunststoff-Folien, Papier und der­ gleichen. In diesem Falle wäre die mehrlagige Kunststoff- Folie der Erfindung nur als "Zwischenprodukt" zu verste­ hen.It should also be expressly stated that the skin like which can only serve as part of a carrier layer, whereby e.g. B. on the opposite side of the adhesive layer other materials are laminated onto the skin, such as Metal foils, other plastic foils, paper and the same. In this case, the multi-layer plastic Understanding film of the invention only as an "intermediate" hen.

Ausführungsbeispiele der Erfindung sind in der beigefüg­ ten Zeichnung dargestellt. Die Figuren der Zeichnung zeigen im einzelnen:Embodiments of the invention are in the attached shown drawing. The figures of the drawing show in detail:

Fig. 1 in vergrößerter Darstellung eine mehrlagige Kunststoff-Folie im Ausschnitt,; Fig. 1 in an enlarged view a multi-layer plastic film in the cutout;

Fig. 2 die Anbringung der Kunststoff-Folie beim Ver­ schließen einer Öffnung; Figure 2 shows the attachment of the plastic film when closing an opening Ver.

Fig. 3 die Herstellung eines mehrlagigen flächigen Kör­ pers aus zwei Kunststoff-Folien gemäß Erfindung. Fig. 3 shows the production of a multi-layered body Kör pers from two plastic films according to the invention.

Fig. 1 zeigt eine koextrudierte Kunststoff-Folie, die eine etwa 50 µm dicke Traghaut 1 aus Polyethylen auf­ weist, auf die eine haftende Selbstklebemasse als Kleb­ schicht 2 aufgebracht ist. Die Klebschicht ist nach außen von einer spröden Kunststoff-Deckschicht 3 überzogen. Die Dicken-Abmessungen der Schichten sind in etwa maßstabsge­ recht dargestellt. Die spröde Kunststoff-Deckschicht besteht im vorliegenden Fall aus einem Polyethylen. Fig. 1 shows a coextruded plastic film, which has an approximately 50 microns thick base 1 made of polyethylene, on which an adhesive self-adhesive layer is applied as an adhesive layer 2 . The adhesive layer is covered on the outside by a brittle plastic cover layer 3 . The thickness dimensions of the layers are shown approximately true to scale. The brittle plastic cover layer in the present case consists of a polyethylene.

Mit Hilfe eines an seiner Unterseite gezackten, hier nur schematisch dargestellten Werkzeuges 5 wird die Folie auf eine Papierbahn 6 aufgedrückt, unterhalb der ein Gegenla­ ger 7 angeordnet ist, das der Kraft des Werkzeuges 5 standhält. Beim Aufdrücken des Werkzeuges auf die Kunst­ stoff-Folie zerspringt und bricht die Deckschicht 3 auf, wie in der Fig. 1 angedeutet. Der Klebstoff der Kleb­ schicht 2 tritt aus den aufgesprengten Löchern heraus und verklebt damit die Papierschicht 6 mit der Traghaut 1.With the help of a serrated on its underside, only schematically shown tool 5 , the film is pressed onto a paper web 6 , below which a Gegenla ger 7 is arranged, which withstands the force of the tool 5 . When pressing the tool on the plastic film shatters and breaks the cover layer 3 , as indicated in Fig. 1. The adhesive of the adhesive layer 2 emerges from the blasted holes and thus glues the paper layer 6 to the support skin 1 .

In der Fig. 2 ist eine andere Anwendungsmöglichkeit dargestellt. Hier wird der Rand 9 eines (unvollständig) dargestellten Kunststoff-Bechers, z. B. aus Polycarbonat, verschlossen. Dies geschieht, indem die durch Koextrusion hergestellte, mehrlagige Kunststoff-Folie 10 gemäß Neue­ rung auf den Rand 9 aufgelegt ist. Die Klebschicht 2 besteht in diesem Falle aus einem Schmelzkleber, der dadurch freigegeben wird, daß während oder nach dem An­ pressen der Folie der Klebstoff durch das Werkzeug 5′ erwärmt wird. Es handelt sich beispielsweise um eine Hochfrequenz-Elektrode. Die spröde Deckschicht 3 wird aufgesprengt, wie dies durch die Punktierung dargestellt ist, wobei mit dem Aufsprengen gleichzeitig der Schmelz­ kleber in der Klebschicht 2 erhitzt wird und aus den auf­ gesprengten Bereichen ausfließt und die Traghaut 1 mit dem Deckelrand verklebt. Mit Hilfe eines Schneidmessers 11 erfolgt ein sauberes Abstanzen der überstehenden Folie.Another possible application is shown in FIG. 2. Here the edge 9 of a (incompletely) shown plastic cup, e.g. B. made of polycarbonate, closed. This is done by placing the multi-layer plastic film 10 produced by coextrusion on the edge 9 according to the new invention. The adhesive layer 2 consists in this case of a hot melt adhesive, which is released in that the adhesive is heated by the tool 5 'during or after pressing on the film. For example, it is a high-frequency electrode. The brittle top layer 3 is blown open, as shown by the dotting, with the blasting simultaneously heating the hot melt adhesive in the adhesive layer 2 and flowing out of the blasted areas and gluing the skin 1 to the lid edge. With the help of a cutting knife 11 , the protruding film is punched cleanly.

In Fig. 3 ist eine weitere Verwendungsmöglichkeit der Kunststoff-Folie gemäß Erfindung zur Herstellung eines mehrlagigen, flächigen Körpers dargestellt. Zwei aufein­ andergelegte, gleiche Kunststoff-Folien 10, 10′ liegen im Bereich der spröden Kunststoff-Beschichtung aufeinander. Mit Hilfe kompatibler Werkzeuge 5, 5′ werden die Folien aufeinandergedrückt, wobei die spröden Deckschichten 3, 3′ aufgesprengt werden und im Bereich der Aufsprengung den Klebstoff austreten lassen bzw. diesen freilegen. Hierdurch erfolgt eine Verklebung der beiden koextrudier­ ten zu einem mehrlagigen, flächigen Körper. Die beiden Kunststoff-Folien 10, 10′ können auch verschieden sein, beispielsweise kann die Traghaut jeweils verschieden dick oder die Klebstoff-Zusammensetzung verschieden sein. Es kann sich auch um zueinander kompatible oder miteinander reagierende Klebstoff-Komponenten handeln, die in Kleb­ schichten 2 und 2′ vorhanden sind.In Fig. 3 is a further possible use is in accordance with the invention a multi-ply of plastic film for producing represented flat body. Two superimposed, the same plastic films 10 , 10 'lie on each other in the area of the brittle plastic coating. With the help of compatible tools 5 , 5 ', the foils are pressed together, the brittle cover layers 3 , 3 ' being blown open and allowing the adhesive to escape or expose them in the area of the blasting. As a result, the two coextruded are bonded to form a multi-layer, flat body. The two plastic films 10 , 10 'can also be different, for example, the base skin can be different in thickness or the adhesive composition can be different. It can also be mutually compatible or mutually reactive adhesive components that are present in adhesive layers 2 and 2 '.

Mit der Folie gemäß Erfindung lassen sich verschiedene Substrate verbinden, beispielsweise Papier, Pappe oder weitere Kunststoff-Folien, aber auch Metall-Folien oder Kombinationen aus den vorgenannten Materialien.Various can be made with the film according to the invention Connect substrates, for example paper, cardboard or other plastic films, but also metal films or Combinations of the above materials.

Bei der Traghaut handelt es sich vorzugsweise um Poly­ ethylen, z. B. low density oder high density PE- sowie um Propylen-Kopolymere. Auch hier sind dem Fachmann weitere Gestaltungsmöglichkeiten bekannt, die die verschiedensten Variationen zulassen.The base skin is preferably poly ethylene, e.g. B. low density or high density PE and um Propylene copolymers. Here, too, the person skilled in the art has more Design options known that the most diverse Allow variations.
