Abstract
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zur Verringerung der Auflagefläche von haftklebenden Laminaten und Laminatabschnitten auf dehäsiven Folien.The present invention relates to a device for reducing the Contact surface of pressure-sensitive adhesive laminates and laminate sections adhesive films.
Die Herstellung haftklebender Laminate und haftklebender Laminatabschnitte ist bekannt. Diese Laminate bestehen aus einer haftklebenden Schicht und gegebenenfalls weiteren, klebenden oder nichtklebenden Schichten (Abdeckfolie, Zwischenschichten, Rückschicht). Dabei kann es sich auch um doppelseitig oder einseitig haftendes Klebeband handeln, welches gegebenenfalls in einzelne Abschnitte (Etiketten) unterteilt ist.The production of pressure sensitive adhesive laminates and pressure sensitive adhesive laminate sections is known. These laminates consist of an adhesive layer and optionally further adhesive or non-adhesive layers (Cover film, intermediate layers, backing layer). It can also be double-sided or single-sided adhesive tape, which possibly divided into individual sections (labels).
Zur Lagerung und zum Transport solcher Klebebänder bzw. Etiketten werden dehäsive Trägerfolien verwendet. Sie verhindern ein ungewolltes Haften der haftklebenden Schicht eines solchen Laminats auf einer fremden Oberfläche und ermöglichen weiterhin ein rückstandsfreies Ablösen dieser haftklebenden Schicht vor der zweckgebundenen Anwendung des haftklebenden Laminats oder Laminatabschnitts.For storing and transporting such adhesive tapes or labels adhesive backing films are used. They prevent unwanted sticking of the pressure-sensitive adhesive layer of such a laminate on a foreign surface and continue to allow residue-free removal pressure-sensitive adhesive layer before the intended use of the pressure-sensitive adhesive laminate or laminate section.
Die zum Ablösen der haftklebenden Schicht aufzuwendende Arbeit wird als Adhäsionsarbeit Wa bezeichnet. Sie wird auch Oberflächenarbeit oder Grenzarbeit genannt und ist das Produkt aus Oberflächenspannung multipliziert mit dem Flächenzuwachs der Auflagenfläche. Unter der Auflagenfläche versteht man hierbei die Kontaktfläche zwischen der haftklebenden Schicht und der dehäsiven Trägerfolie.The work to be done to remove the pressure-sensitive adhesive layer is referred to as the adhesion work W a . It is also called surface work or marginal work and is the product of surface tension multiplied by the surface area increase of the surface area. The contact surface here means the contact surface between the pressure-sensitive adhesive layer and the adhesive backing film.
Die Oberflächenspannung ist abhängig von den Materialeigenschaften der dehäsiven Trägerfolie und von den Materialeigenschaften der haftklebenden Schicht. The surface tension depends on the material properties of the adhesive backing film and the material properties of the pressure-sensitive adhesive Layer.
Im allgemeinen wird die für eine spezielle haftklebende Schicht gewünschte Adhäsionsarbeit dadurch erreicht, dass man eine dehäsive Trägerfolie verwendet, die eine geeignete Oberflächenspannung besitzt. Wenn die Materialeigenschaften der dehäsiven Trägerfolie jedoch nicht verändert werden können, z. B. aufgrund von bestehenden Inkompatibilitäten zwischen den Materialien der haftklebenden Schicht und den Materialien der dehäsiven Trägerfolie, kann die aufzuwendende Adhäsionsarbeit so hoch werden, dass ein rückstandsfreies Ablösen der klebenden Schicht unmöglich wird. Es treten z. B. Riss- oder Fetzenbildung auf, die auf einen Verlust der Kohäsion der haftklebenden Schicht zurückzuführen sind.Generally, the one desired for a particular pressure sensitive adhesive layer Adhesion work achieved by using a adhesive backing film used, which has a suitable surface tension. If the However, the material properties of the adhesive backing film were not changed can be, e.g. B. due to existing incompatibilities between the materials of the pressure-sensitive adhesive layer and the materials of the adhesive backing film, can be the work of adhesion become so high that the adhesive layer can be removed without residue becomes impossible. Z. B. cracking or scrapping on a Loss of cohesion of the pressure-sensitive adhesive layer can be attributed.
Solche Inkompatibilitäten zwischen den Materialien der haftklebenden Schicht und den Materialien der dehäsiven Trägerfolie treten häufig dann auf, wenn die haftklebende Schicht weitere Inhaltsstoffe enthält. Hierbei kann es sich z. B. um chemisch aktive Stoffe, pharmazeutische Wirkstoffe oder biologisch aktives Material handeln. Wegen der begrenzten Zahl von Materialien, die für die Herstellung von dehäsiven Trägerfolien zur Verfügung stehen, können dann die haftklebenden Schichten nicht mit einer beliebigen Adhäsionsarbeit von der dehäsiven Trägerfolie gelöst werden.Such incompatibilities between the materials of the pressure sensitive adhesive Layer and the materials of the adhesive backing film often occur if the pressure-sensitive adhesive layer contains other ingredients. Here it can z. B. chemically active substances, active pharmaceutical ingredients or act biologically active material. Because of the limited number of Materials available for the manufacture of adhesive backing sheets stand, the pressure-sensitive adhesive layers can not with any Adhesion work can be solved from the adhesive backing film.
Nun könnte dieses Problem grundsätzlich durch Veränderung der Materialeigenschaften der haftklebenden Schicht gelöst werden. Wegen der benötigten Hafteigenschaften der haftklebenden Schicht für die zweckgebundene Verwendung besteht jedoch nur ein sehr geringer Spielraum zur Veränderung diese Materialeigenschaften.Now this problem could basically be changed Material properties of the pressure-sensitive adhesive layer are solved. Because of the required adhesive properties of the pressure-sensitive adhesive layer for the However, there is very little dedicated use Scope for changing these material properties.
Der Erfindung liegt also die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Verfügung zu stellen, durch die das Ablösen eines haftklebenden Laminats von einer dehäsiven Trägerfolie bei einer vorgegebenen Zusammensetzung der haftklebenden Schicht des Laminats mit beliebiger, insbesonders geringer Adhäsionsarbeit ermöglicht wird. The invention is therefore based on the object, a method and a To provide device by which the detachment of a pressure-sensitive laminates from a adhesive backing film with a predetermined composition of the pressure-sensitive adhesive layer of the laminate is made possible with any, especially low, adhesion work.
Gelöst wird die Aufgabe durch eine Vorrichtung zur Erleichterung des Ablösens eines haftklebenden Laminats oder haftklebender Laminatabschnitte von einer dehäsiven Trägerfolie, die dadurch gekennzeichnet ist, dass diese Trägerfolie auf der die haftklebende Schicht des haftklebenden Laminats berührenden Seite Erhebungen besitzt, die eine Verkleinerung der Auflagefläche des haftklebenden Laminats oder Laminatabschnitts bewirken. In einer besonderen Ausführungsform kann es sich bei dem haftklebenden Laminat um ein Transdermales Therapeutisches System (TTS) handeln, welches eine Rückschicht, einen pharmazeutischen Wirkstoff (z. B.: Estradiol, Buprenorphin, Rivastigmin, Testosteron, Levonorgestrel, Clonidin, Nicotin, Nitroglycerin, Norethisteronacetat, Galanthamin, Oxybutynin, Doxorubicin, Amifostin, Clotrimazol, Fentanyl, Nifedipin etc.) enthaltende haftklebende Schicht und ggf. eine wirkstoffhaltige Reservoirschicht und ggf. eine die Freisetzungsgeschwindigkeit des Wirkstoffs kontrollierende Membran enthält.The task is solved by a device to facilitate the Peeling off a pressure sensitive adhesive laminate or pressure sensitive adhesive Laminate sections of a adhesive backing film, which thereby is characterized in that this carrier film on which the pressure-sensitive adhesive layer of the pressure-sensitive adhesive laminate touching side elevations, which Reduction of the contact area of the pressure-sensitive adhesive laminate or Effect laminate section. In a particular embodiment, it can the pressure-sensitive adhesive laminate is a transdermal therapeutic Act (TTS) system, which is a backing layer, a pharmaceutical Active ingredient (e.g.: estradiol, buprenorphine, rivastigmine, testosterone, Levonorgestrel, clonidine, nicotine, nitroglycerin, norethisterone acetate, Galanthamine, oxybutynin, doxorubicin, amifostine, clotrimazole, fentanyl, Nifedipine etc.) containing pressure-sensitive adhesive layer and possibly an active ingredient-containing layer Reservoir layer and possibly the release rate of the Contains active ingredient-controlling membrane.
Dadurch, dass die an sich flache dehäsive Trägerfolie Erhebungen aufweist, wird gewährleistet, dass die haftklebende Schicht des haftklebenden Laminats die dehäsive Trägerfolie nicht vollflächig, sondern nur an ihren Erhebungen - insbesondere an deren oberen Enden - berührt. Dies führt zu einer deutlichen Reduktion der Auflagefläche.Because the flat, adhesive adhesive backing film has elevations, ensures that the pressure-sensitive adhesive layer of the pressure-sensitive adhesive Laminate the adhesive backing film not all over, but only on their Elevations - especially at their upper ends - touched. this leads to a significant reduction in the contact area.
Die Erhebungen sind vorzugsweise zwischen 20 und 400 µm hoch. Hinsichtlich der geometrischen Form der Erhebungen gibt es keine speziellen Anforderungen, quadratische, rechteckige, ovale und runde Erhebungen sind bevorzugt. Die einzelnen Erhebungen können an ihrem oberen Ende abgeflacht sein.The elevations are preferably between 20 and 400 microns high. There are none with regard to the geometrical shape of the elevations special requirements, square, rectangular, oval and round Surveys are preferred. The individual surveys can be made on their be flattened at the top.
Die Erhebungen können separate Formteile aus einem Material sein, die durch Aufkleben, z. B. mit einem bei Raumtemperatur bis ca. 50°C nicht klebendem Material, beispielsweise Heissschmelzpolymeren, auf die dehäsive Trägerfolie aufgebracht werden können. Es können für diesen Zweck auch Permanentkleber oder Heissiegelmedien verwendet werden.The elevations can be separate molded parts made of one material by sticking, e.g. B. not with at room temperature to about 50 ° C. adhesive material, for example hot melt polymers, on the adhesive backing film can be applied. It can be for this Permanent adhesive or heat sealing media can also be used for this purpose.
In einer weiteren Ausführungsform können die Erhebungen in der Oberfläche der dehäsiven Trägerfolie enthalten sein. Hierunter ist zu verstehen, dass die die Oberflächenstruktur der an sich planaren dehäsiven Trägerfolie dergestalt ist, dass sie diese Erhebungen zeigt. Diese an der Oberfläche befindlichen Erhebungen bestehen dann aus demselben Material wie die Trägerfolie. Sie können z. B. durch mechanische Verformung mittels Prägewerkzeugen oder Walzen in die Trägerfolie eingebracht werden. Hierbei wird Druck und ggf. eine erhöhte Temperatur angewandt. Auch können die Erhebungen in Form der besagten Oberflächenstruktur durch Tiefziehen in die dehäsive Trägerfolie eingebracht werden.In a further embodiment, the elevations in the surface the adhesive backing film may be included. This means that the the surface structure of the inherently planar adhesive carrier film is such that it shows these surveys. This on the surface existing surveys then consist of the same material as the Carrier film. You can e.g. B. by means of mechanical deformation Embossing tools or rollers are introduced into the carrier film. Pressure and, if necessary, an elevated temperature are used here. Also can carry out the surveys in the form of said surface structure Thermoforming can be introduced into the adhesive backing film.
Die Zahl und die Abstände der einzelnen Erhebungen kann den jeweiligen Bedürfnissen - die abhängig von dem Ausmass der Adhäsionsarbeit ist - angepasst werden. Bei starker Haftung (grosse Adhäsionskraft) verwendet man viele Erhebungen mit kleinen Abständen, bei geringerer Haftung verwendet man weniger Erhebungen mit grösseren Abständen. Typischerweise liegt die Zahl der Erhebungen zwischen 1 und 9 pro cm2, während die Abstände der Erhebungen zwischen 2 und 9 mm liegen.The number and spacing of the individual surveys can be adapted to the respective needs - which depends on the extent of the adhesion work. With strong adhesion (high adhesive force), many surveys with small distances are used, with less adhesion one uses fewer surveys with larger distances. The number of elevations is typically between 1 and 9 per cm 2 , while the spacing of the elevations is between 2 and 9 mm.
Die Materialien, die für die dehäsive Trägerfolie verwendet werden, sind dem Fachmann bekannt. Es kann sich dabei um Polyethylen, Polypropylen, Polyethylenterephthalat und ähnliche Polymere handeln, die ggf. mit einer Silikon-, einer Fluorpolymer oder einer Fluorsilikonschicht auf einer Seite ausgerüstet sein können, welche dadurch besonders dehäsiv wird.The materials used for the adhesive backing sheet are that Known specialist. It can be polyethylene, polypropylene, Polyethylene terephthalate and similar polymers, possibly with a Silicone, a fluoropolymer or a fluorosilicone layer on one side can be equipped, which makes it particularly adhesive.
