Abstract

The invention relates to a four-ply composite film of a paper/silicone/hot-melt adhesive/metal, preferably aluminium, structure. The metal foil may have a special colour finish, for example be anodised. The UV-resistant hot-melt adhesive, preferably copolyamide, is adjusted such that it firmly bonds the metal foil to the underlying surface upon heating and such that, in the cold state, the metal foil can be removed again along with the hot-melt adhesive layer totally without leaving any residual material from the underlying surface. According to the invention, the adhesion of the hot-melt adhesive on the metal and the adhesion of the silicone on the paper are stronger than the adhesion of the hot-melt adhesive on the silicone layer. As a result, the hot-melt adhesive/metal foil, which is reinforced by the hot-melt adhesive, can be easily peeled off the paper/silicone film for the purpose of using as a covering (masking), for example of glass surfaces and other surfaces. The procedure adopted for producing the four-ply composite film is that first of all the hot-melt adhesive layer is applied in a cold low-viscosity state to the silicone side of the paper/silicone film, subsequently the metal foil is laminated onto the hot-melt adhesive side and, in the case of perforation, the entire four-ply composite film is punched, preferably hole-punched. <IMAGE>

Description

Die Erfindung betrifft eine vierlagige Verbundfolie mit dem Aufbau Papier-Silikon- Kunststoff-Metall.The invention relates to a four-layer composite film with the structure of paper-silicone Plastic-metal.

Verbundfolien - auch mit dem Aufbau Papier-Silikon-Kunststoff-Metall - sind nicht neu. Jedoch die Verwendung von Schmelzkleber als Kunststoffschicht in einer vierlagigen Verbundfolie - insbesondere zur Stabilisierung einer vorzugsweise dünnen Metallfolie bei nachträglicher Ablösbarkeit der Schmelzkleber-Metall-Folie von der Papier-Silikon-Folie - ist bisher unbekannt.Composite foils - also with the structure paper-silicone-plastic-metal - are not New. However, the use of hot melt adhesive as a plastic layer in one four-layer composite film - in particular to stabilize a preferably thin Metal foil with subsequent detachability of the hot-melt metal foil from the Paper-silicone film - is so far unknown.

Der Erfindung liegt gemäß Anspruch 1 die Aufgabe zugrunde, eine vierlagige Verbundfolie mit dem Aufbau Papier-Silikon-Kunststoff-Metall zur Verfügung zu haben, in der die Kunststoffschicht ein Schmelzkleber ist. Dazu muß der Schmelz­ kleber so beschaffen sein, daß durch ihn die Metallfolie auf eine flächige Unterlage, z. B. Glas, mittels Erwärmung fest haftend aufgebracht und in kaltem Zustand von der Unterlage unversehrt und ohne Rückstande auf der Unterlage wieder abgenom­ men werden kann.The invention is based on the object of claim 1, a four-layer Composite film with the construction paper-silicone-plastic-metal available too in which the plastic layer is a hot melt adhesive. This requires the enamel glue in such a way that the metal foil is placed on a flat surface, e.g. B. glass, firmly adhered by heating and in the cold state of the document undamaged and removed without residue on the document men can be.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Kunststoffschicht ein gegen ultraviolette Strahlung beständiger Schmelzkleber, vorzugsweise Copolyamid, verwendet wird, welcherThis object is achieved in that a plastic layer hot melt adhesive resistant to ultraviolet radiation, preferably copolyamide, whichever is used

  • - an der Metallfolie im normalen Temperaturbereich fest haftet und diese da­ durch stabilisiert - adheres firmly to the metal foil in the normal temperature range and there stabilized by  
  • - an der Silikonschicht relativ weniger fest haftet, so daß die Kunststoff-Metall- Folie leicht von der Papier-Silikon-Folie abgezogen werden kann und- adheres to the silicone layer relatively less firmly, so that the plastic-metal Film can be easily peeled off the paper-silicone film and
  • - die Metallfolie nach Entfernung der Papier-Silikon-Folie flächig auf einer Unterlage, z. B. Glas, mittels Erwärmung so zur Haftung bringt, daß die Schmelzkleber-Metall-Folie in kaltem Zustand unversehrt und ohne Rückstände auf der Unterlage wieder abgenommen werden kann.- The metal foil after removal of the paper-silicone foil flat on one Underlay, e.g. B. glass by heating so that the liability Hot-melt metal foil in the cold state intact and without residues can be removed again on the pad.

Damit die Metallfolie, die naturgemäß lichtundurchlässig ist, auch transparent verwendet werden kann, z. B. als selbsthaftende Beschichtung auf der Glasscheibe, hat die gesamte vierlagige Verbundfolie nach Anspruch 2 eine gleichmäßige Perfora­ tion, vorzugsweise eine feine Lochstanzung. Für den Fall anderweitiger Verwendung kann die Perforation auch aus Ausstanzungen bestehen, die eine bestimmte Muste­ rung oder sonstige bildhafte Gestaltung bewirken.So that the metal foil, which is naturally opaque, is also transparent can be used e.g. B. as a self-adhesive coating on the glass pane, the entire four-layer composite film according to claim 2 has a uniform perfora tion, preferably a fine hole punch. In the event of any other use the perforation can also consist of punched-out holes that have a certain pattern effect or other pictorial design.

Außerdem ist die Metallfolie, vorzugsweise Aluminium, gemäß Anspruch 3 zum Zwecke der Farbgestaltung, zum Schutz gegen Korrosion oder aus anderen Gründen besonders ausgerüstet, z. B. eloxiert.In addition, the metal foil, preferably aluminum, according to claim 3 Purposes of color design, protection against corrosion or other reasons specially equipped, e.g. B. anodized.

Die für die erfindungsgemäßen Zwecke erforderliche Verbundfolie mit gleichmäßig dünner Schmelzkleberschicht wird nach Anspruch 4 dadurch erhalten, daßThe composite film required for the purposes of the invention with uniform thin hot melt adhesive layer is obtained according to claim 4 in that

  • - der Schmelzkleber zunächst in kaltem Zustand gleichmäßig dünnflüssig auf die silikonbeschichtete Seite des Papiers aufgetragen,- The hot melt adhesive is first applied in a thin, even, thin layer on the silicon-coated side of the paper applied,
  • - anschließend die Metallfolie auf die Schmelzkleberseite der dreilagigen Folie Papier-Silikon-Schmelzkleber warm aufkaschiert und- Then the metal foil on the hot melt adhesive side of the three-layer foil Paper-silicone hot-melt adhesive laminated warm and
  • - zur Vermeidung von Schmelzkleberrückständen in den Stanzlöchern die gesam­ te vierlagige Verbundfolie gestanzt, insbesondere lochgestanzt wird.- to avoid hot melt adhesive residues in the punch holes te four-layer composite film is punched, in particular hole punched.

Im Folgenden wird die Erfindung anhand von lediglich eine Ausprägung darstellen­ den Zeichnungen näher erläutert. Es zeigenIn the following, the invention will be based on only one variant  the drawings explained in more detail. Show it

Die Glasplatte hat das Bezugszeichen 6.In the figures, the four-layer composite film is identified by the reference number 1 , the paper layer by 2 , the silicone layer by 3 , the hot melt adhesive layer by 4 and the metal film by 5 . The glass plate has the reference number 6 .

Die durch die Erfindung erreichten Vorteile sind im wesentlichen folgende:The advantages achieved by the invention are essentially the following:

Die Verwendung von Schmelzkleber in Verbindung mit Folie ist wegen der erforder­ lichen Wärmeeinwirkung zur Aktivierung des Klebers nur bei Metallfolien sinnvoll.The use of hot melt adhesive in connection with film is required because of the The effect of heat to activate the adhesive only makes sense with metal foils.

Außerdem ist ist der erforderliche gleichmäßig dünne Auftrag des Schmelzklebers auf bereits perforierte Metallfolien schwierig. Denn er dringt allzu leicht durch die Perforation auf die andere Seite der Folie oder bildet in den Perforationsaussparun­ gen einen Film, der die Transparenz aufhebt. Die erfindungsgemäße vierlagige Verbundfolie erlaubt es, diese Nachteile zu vermeiden. Der Schmelzkleber wird nicht direkt auf die Metallfolie, sondern auf die Silikonbeschichtung des Papiers aufgetra­ gen. Damit das Papier sich nicht durch Erwärmung wellt, erfolgt das Auftragen des Schmelzklebers in kaltem und dennoch flüssigem Zustand. Anschließend wird auf die so vorgefertigte Papier-Silikon-Schmelzkleber-Folie mittels leichter Erwärmung die Metallfolie aufkaschiert. Die Schmelzkleberschicht liegt dadurch besonders gut geschützt in der Verbundfolie.In addition, the required evenly thin application of the hot melt adhesive is on already perforated metal foils difficult. Because it penetrates all too easily Perforation on the other side of the film or forms in the perforation recess a film that removes transparency. The four-layer according to the invention Composite foil makes it possible to avoid these disadvantages. The hot melt adhesive won't directly on the metal foil, but on the silicone coating of the paper So that the paper does not curl when heated, the Hot melt adhesive in a cold but still liquid state. Then the prefabricated paper-silicone hot-melt adhesive film by means of gentle heating Laminated metal foil. As a result, the hot melt adhesive layer lies particularly well protected in the composite film.

Die vierlagige Verbundfolie läßt sich - ohne Beeinträchtigung der innen liegenden Schmelzkleberschicht - bei allen weiteren Bearbeitungen gut handhaben, leicht zu­ schneiden und insbesondere beliebig stanzen. Die Schmelzkleber-Metall-Folie läßt sich für die weitere Verwendung in gelochtem und ungelochtem Zustand einfach von der Papier-Silikon-Folie abziehen, auch wenn die Metallfolie sehr dünn ist, da diese durch die Schmelzkleberschicht dehnbar verstärkt wird.The four-layer composite film can be - without affecting the inside Hot melt adhesive layer - easy to handle for all further processing, easy to  cut and in particular punch as desired. The hot melt metal foil leaves for further use in perforated and non-perforated condition peel off the paper-silicone film, even if the metal film is very thin, as this is stretchably reinforced by the hot melt adhesive layer.

Insgesamt kommt der erfindungsgemäßen Verbundfolie schon wegen ihrer vielseiti­ gen Verwendbarkeit eine besondere Bedeutung zu. Denn sie erlaubt es nicht nur, z. B. zum Sicht- und Sonnenschutz, Glasflächen unter Aufrechterhaltung der Trans­ parenz problemlos wiederentfernbar und sogar wiederverwendbar zu beschichten. Sie bewährt sich auch auf zahlreichen anderen Oberflächen, z. B. von Baueleinenten, Ma­ schinenteilen, Geschenkpackungen usw., die aus den verschiedensten Materialien bestehen können, wenn es darum geht, diesen ein praktisches, optisch ansprechendes und angemessen schützendes Outfit aus Metall zu geben.Overall, the composite film according to the invention comes because of its versatility of particular importance. Because it not only allows e.g. B. for privacy and sun protection, glass surfaces while maintaining the trans parenz easily removable and even reusable to coat. they also proves itself on numerous other surfaces, e.g. B. from Baueleinenten, Ma rail parts, gift packs, etc., made from a wide variety of materials can exist when it comes to this a practical, visually appealing and give an appropriately protective metal outfit.
