Description
Die Erfindung betrifft ein Laminierfolienset zum Einschweißen von Blattgut aus zwei übereinanderliegenden, vorzugsweise im Umriss rechteckigen Laminierfolien, die als Verbundfolien mit jeweils einer Folienschicht und einer darauf jeweils innenseitig aufgebrachten Klebeschicht ausgebildet sind, welche bei Umgebungstemperatur nicht klebfähig, jedoch durch Einwirkung von Druck und/oder Hitze aktivierbar ist, wobei zumindest eine der Folienschichten aus einem transparenten, insbesondere glasklaren Kunststoff besteht. The invention relates to a Laminierfolienset for welding sheet material from two superimposed, preferably in outline rectangular laminating films, which are formed as composite films, each having a film layer and an adhesive layer applied thereto on the inside, which is not tacky at ambient temperature, but by the action of pressure and / or Heat can be activated, wherein at least one of the film layers consists of a transparent, especially crystal-clear plastic.
Zum Schutz von Blattgut, insbesondere von wertvollen Dokumenten, ist es bekannt, das Blattgut mit einer Laminierfolie zu verschweißen. Dies geschieht im nichtindustriellen Bereich, d.h. im Büro- und Privatbereich, mit Hilfe von in der Regel als Tischgeräte ausgebildeten Laminiergeräten. Sie haben ein Gehäuse, in dem eine Laminiereinrichtung angeordnet ist. Zwischen einer Zuführöffnung auf einer Seite und einer Austrittsöffnung auf der anderen Seite des Gehäuses erstreckt sich durch das Gehäuse ein Durchlaufkanal, dem die Laminiereinrichtung zugeordnet ist. Letztere weist in der Regel mindestens ein Walzenpaar, teilweise auch mehrere Walzenpaare, aus jeweils zwei übereinander angeordneten, einen Laminierspalt ausbildenden Laminierwalzen auf, wobei der Laminierspalt so eingestellt ist, dass die Kombination aus Blattgut und Laminierfolie in dem Laminierspalt einem erheblichen Druck ausgesetzt wird. Bei Heißlaminiergeräten ist zumindest eine der Laminierwalzen, in der Regel beide, beheizt, so dass die Kombination aus Blattgut und Laminierfolie zusätzlich erhitzt wird. Beim Durchlauf verklebt die Laminierfolie aufgrund der Aktivierung der Klebeschicht mittels Druck und/oder Hitze mit dem einzuschweißenden Blattgut. For the protection of sheet material, in particular of valuable documents, it is known to weld the sheet material with a laminating film. This happens in the non-industrial area, i. in the office and private sector, with the help of usually designed as a tabletop laminators. They have a housing in which a laminator is arranged. Between a feed opening on one side and an outlet opening on the other side of the housing extends through the housing a passage channel, which is associated with the laminator. The latter generally has at least one pair of rollers, in some cases also a plurality of pairs of rollers, each consisting of two stacked laminating rollers forming a laminating gap, wherein the laminating gap is adjusted such that the combination of sheet material and laminating film is subjected to considerable pressure in the laminating gap. In Heißlaminiergeräten at least one of the laminating rollers, usually both, heated, so that the combination of sheet material and laminating film is additionally heated. During the passage, the laminating film adheres due to the activation of the adhesive layer by means of pressure and / or heat with the sheet material to be welded.
In der Regel wird zum Einschweißen von Blattgut ein Laminierfolienset aus zwei deckungsgleich übereinanderliegenden Laminierfolien verwendet. Für den Laminiervorgang wird dann das Blattgut zwischen die beiden Laminierfolien eingelegt und die Kombination aus Laminierfolien und darin eingelegtem Blattgut dem Laminiergerät zugeführt. Mit Hilfe eines solchen Laminierfoliensets kann das Blattgut vollständig eingeschweißt werden und ist dann gegen äußere Einwirkung, insbesondere gegen Verschmutzung und Flüssigkeit geschützt. As a rule, a laminating film set of two overlapping laminating films is used for welding sheet material. For the lamination process, the sheet material is then inserted between the two laminating films and the combination of laminating films and sheet material inserted therein is fed to the laminating device. With the help of such a Laminierfoliensets the sheet material can be completely sealed and is then protected against external influences, especially against contamination and liquid.
Die Laminierfolien bekannter Laminierfoliensets sind als Verbundfolien ausgebildet, bei denen jeweils eine Folienschicht aus zum Beispiel Polyethylen oder Polypropylen innenseitig mit einer Klebeschicht kaschiert ist, die bei Umgebungstemperatur nicht oder kaum klebfähig ist. Dabei kann unterschieden werden zwischen druckempfindlichen Haftklebern, die ihre Klebfähigkeit durch Einwirkung von Druck erhalten und deshalb auch nicht der Zuführung thermischer Energie bedürfen, und durch Hitze aktivierbaren Klebstoffen, wie beispielsweise Ethylen-Vinylacetat-Copolymer (EVA), welche in dem Laminiergerät erhitzt werden müssen, um ihre Klebfähigkeit zu entwickeln. Die hierfür notwendige Temperatur liegt dann unterhalb derjenigen Temperatur, die die Folienschicht beeinträchtigen könnte. The laminating films of known laminating film sets are designed as composite films in which a film layer of, for example, polyethylene or polypropylene is laminated on the inside with an adhesive layer which is not or barely adhesive at ambient temperature. A distinction can be made between pressure-sensitive adhesives, which receive their adhesiveness by the action of pressure and therefore do not require the supply of thermal energy, and heat activatable adhesives, such as ethylene-vinyl acetate copolymer (EVA), which must be heated in the laminator to develop their adhesiveness. The temperature required for this is then below the temperature that could affect the film layer.
Zumindest eine der Laminierfolien hat eine Folienschicht, die wenigstens transparent, vorzugsweise glasklar ist, sodass das damit eingeschweißte Dokument sichtbar und auch identifizierbar ist. In der Regel sind beide Laminierfolien gleich ausgebildet. Vor dem Laminiervorgang sind sie häufig wegen der aufgebrachten Klebeschicht opak. Durch die Einwirkung von Druck und gegebenenfalls Hitze wird auch die Klebeschicht transparent. At least one of the laminating films has a film layer which is at least transparent, preferably crystal-clear, so that the document welded thereto is visible and also identifiable. In general, both laminating films are the same. Before the lamination process, they are often opaque because of the applied adhesive layer. Due to the effect of pressure and possibly heat, the adhesive layer also becomes transparent.
Der Erfindung liegt die Aufgabe zugrunde, ein Laminierfolienset derart auszubilden, dass er verbesserte Eigenschaften aufweist. The invention has for its object to form a Laminierfolienset such that it has improved properties.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Folienschichten aus einem biologisch abbaubaren Kunststoff, insbesondere einem Biokunststoff, bestehen, und dass die Laminierfolien im Bereich zumindest einer Kante miteinander verbunden sind. Grundgedanke der Erfindung ist es also, ein Laminierfolienset zur Verfügung zu stellen, das einerseits einfach handhabbar und andererseits aufgrund seiner biologischen Abbaubarkeit ökologisch besonders wertvoll ist. Die verbesserte Handhabbarkeit ergibt sich daraus, dass die beiden Laminierfolien miteinander verbunden sind, so dass sie in einer definierten Position zueinander verbleiben, wenn das zu schützende Blattgut zwischen die beiden Laminierfolien eingelegt und die Kombination aus Laminierfolienset und Blattgut in das Laminiergerät eingeführt wird. This object is achieved according to the invention in that the foil layers consist of a biodegradable plastic, in particular a bioplastic, and in that the laminating foils are connected to one another in the region of at least one edge. The basic idea of the invention is therefore to provide a laminating film set which, on the one hand, is easy to handle and, on the other hand, is ecologically particularly valuable on account of its biodegradability. The improved handling results from the fact that the two laminating films are connected to each other so that they remain in a defined position to each other when the sheet material to be protected between the two laminating and inserted the combination of laminating film set and sheet material in the laminator.
Die biologische Abbaubarkeit des für die Folienschichten verwendeten Kunststoffs ist nach
In Ausgestaltung der Erfindung ist vorgesehen, dass der Rohstoff Zucker, Zuckerderivate, Stärke, Stärkederivate, Zellulose, Zellulosederivate und/oder Lingnin ist. Stattdessen oder in Kombination damit kann der Rohstoff aber auch ein Polylactidaccid (PLA) und/oder eine Polyhydroxyfettsäure (PHF), insbesondere ein Polyhydroxybutyrat (PHB) und/oder Polyhydroxyvalerat (PHV) sein. Polylactide sind biologisch abbaubare Polyester und werden aus dem Monomer Milchsäure polymerisiert, wobei die Milchsäureproduktion vorrangig unter Nutzung von Maisstärke erfolgt. Polyhydroxyfettsäuren sind durch die Einwirkung von Bakterien oder Pilzen aus Zucker oder Stärke gewonnene thermoplastische Polyester. Alternativ dazu kann der Biokunststoff auch ein fossiler Rohstoff sein. In an embodiment of the invention it is provided that the raw material is sugar, sugar derivatives, starch, starch derivatives, cellulose, cellulose derivatives and / or Lingnin. Instead or in combination therewith, the raw material may also be a polylactidacid (PLA) and / or a polyhydroxy-fatty acid (PHF), in particular a polyhydroxybutyrate (PHB). and / or polyhydroxyvalerate (PHV). Polylactides are biodegradable polyesters and are polymerized from the monomer lactic acid, the production of lactic acid is primarily using corn starch. Polyhydroxy fatty acids are thermoplastic polyesters obtained by the action of bacteria or fungi from sugar or starch. Alternatively, the bioplastic may also be a fossil resource.
Der biologisch abbaubare Rohstoff sollte zumindest 50%, vorzugsweise mindestens 80% in den Folienschichten vorhanden sein. Der Rest kann dann aus geeigneten Hilfs- und Zusatzstoffen, wie Stabilisatoren, Antistatika oder dergleichen, bestehen. The biodegradable raw material should be at least 50%, preferably at least 80% present in the film layers. The remainder may then consist of suitable auxiliaries and additives, such as stabilizers, antistatic agents or the like.
Die Handhabbarkeit des Laminierfoliensets wird noch verbessert, wenn die Laminierfolien im Bereich zumindest zweier aneinander grenzender Kanten miteinander verbunden sind, insbesondere verschweißt sind. Dies erleichtert das zentrierte Einlegen des einzuschweißenden Blattgutes und vermeidet weitgehend ein Verrutschen des Blattgutes bei der anschließenden Handhabung zum Zwecke des Einführens in das Laminiergerät. Insoweit noch bessere Verhältnisse lassen sich erreichen, wenn die Laminierfolien nach Art einer Tasche ausgebildet sind, also nur noch an einer Kante nicht miteinander verschweißt sind, über die dann das Blattgut zwischen die beiden Laminierfolien eingeschoben werden kann. The handling of the laminating film set is further improved if the laminating films are joined together in the region of at least two adjacent edges, in particular welded. This facilitates the centered insertion of the sheet material to be welded and largely avoids slippage of the sheet material in the subsequent handling for the purpose of insertion into the laminator. Insofar even better conditions can be achieved if the laminating films are designed in the manner of a pocket, that is, they are not welded together at one edge, over which the sheet material can then be inserted between the two laminating films.
