Abstract
Description
Die Erfindung betrifft eine Verpackung für kalterstarrende Massen, insbesondere Schmelzkleber, welche heiss in die Verpackung einfüllbar sind, wobei die Verpackung mehrschichtig aufgebaut ist, zumindest eine Schicht der Verpackung aus Papier, Kanon und/ oder Wellpappe besteht und eine weitere Schicht, die nach dem Einbringen der heissen, kalterstarrenden Masse zwischen der vorgenannten Schicht und der kalterstarrenden Masse angeordnet ist, hauptsächlich aus einer Kunststoffmasse besteht.The invention relates to packaging for cold stare Masses, especially hot melt adhesives, which are hot in the packaging fillable are, the packaging is constructed in several layers, at least a layer of packaging made of paper, canon and / or corrugated cardboard and there is another layer which, after the hot, freezing mass between the aforementioned layer and the cold-rigid mass is arranged, mainly from a plastic mass consists.
Das Handling von kalterstarrenden Massen, d.h. insbesondere restklebrigen Schmelzklebstoffen, steht auch heute noch im Fokus der Entwicklung, da dieses Problem derzeit immer noch einer Lösung bedarf. Aspekte, wie umweltschonende, anwenderfreundliche und kostengünstige Verpackungen, sind dabei besonders relevant.The handling of cold stare Masses, i.e. especially residual hot melt adhesives still in focus of development today because of this problem right now still a solution requirement. Aspects such as environmentally friendly, user-friendly and inexpensive packaging, are particularly relevant.
Derzeit kommen oftmals handelsübliche silikonisierte Verpackungen zum Einsatz, welche insbesondere den Nachteil aufweisen, dass sich die kalterstarrenden Massen schlecht aus diesen lösen lassen. Die anhaftenden Verpackungsreste führen zumindest mittelfristig zu unerwünschten Verunreinigungen (Cracking) in den Verarbeitungsanlagen.Commercial siliconized products are often currently available Packaging for use, which has the disadvantage in particular that the cold-staring masses are difficult to remove from them. The adherent packaging remnants lead at least in the medium term to undesirable Contamination (cracking) in the processing plants.
Durch die
Die vorgeschlagene Verpackung besteht somit zumindest aus drei Schichten, wobei eine Trennschicht unlösbar mit der äußeren Schicht, welche aus Karton oder Wellpappe besteht, verbunden ist und einer weiteren Trennschicht, welche mit der kalterstarrenden Masse verbunden ist. Diese Verpackung, da zumindest aus drei Schichten bestehend, ist aufwendig herzustellen und somit kostenintensiv, neigt im Berarbeitungsprozeß zu unerwünschten Verunreinigungen und die beiden äußeren, verbundenen Schichten sind nur aufwendig zu entsorgen oder einer erneuten Nutzung zuzuführen.The proposed packaging exists thus at least from three layers, one separating layer being insoluble with the outer layer, which consists of cardboard or corrugated cardboard, is connected and one another separating layer, which is connected to the cold-setting mass is. This packaging, since it consists of at least three layers, is complex to manufacture and therefore expensive, tends to undesirable in the editing process Impurities and the two outer, connected layers are difficult to dispose of or to be reused.
Aufgabe der Erfindung ist es, eine Verpackung der vorgenannten Art bereitzustellen, die sich effektiv herstellen läßt und deren äußere Schicht sich umweltgerecht verwerten läßt. Außerdem sollen unerwünschte Verunreinigungen im Verarbeitungsprozeß verursacht durch die mit der kalterstarrenden Masse verbundenen Schicht entfallen.The object of the invention is a Provide packaging of the aforementioned type that is effective can produce and the outer layer can be recycled in an environmentally friendly manner. In addition, should undesirable Contamination in the processing process caused by the the cold-rigid mass associated layer is eliminated.
Die Aufgabe der Erfindung wird durch die Merkmale des Anspruch 1 gelöst. Erfindungswesentlich ist dabei, dass die Schicht, die nach dem Einbringen der heißen, kalterstarrenden Masse zwischen der äußeren Schicht und der kalterstarrenden Masse angeordnet ist, mit der äußeren Schicht lösbar und mit der kalterstarrenden Masse unlösbar verbunden ist.The object of the invention is achieved by solved the features of claim 1. It is essential to the invention that the layer after the introduction the hot, cold-setting mass between the outer layer and the cold-setting Mass is arranged with the outer layer solvable and is inextricably linked to the cold-setting mass.
Die Bezeichnung äußere Schicht ist im Sinne der Erfindung als weiter von der kalterstarrenden Masse entfernt zu verstehen. Im Sinne der Erfindung kann also auch noch zumindest eine weitere Schicht angeordnet sein, welche noch weiter von der kalterstarrenden Masse entfernt ist. Beispielsweise kann als äußerste Umhüllung bzw. Schicht eine Transportverpackung angeordnet sein.The term outer layer is in the sense of Invention as further away from the cold-setting mass understand. In the sense of the invention, therefore, at least another layer may be arranged, which is still further from the freezing mass is removed. For example, the outermost wrapping or Layer a transport packaging may be arranged.
Kunststoffmassen sind im Sinne der Erfindung an sich bekannte Kunststoffe oder Kunststoffgemische, die in Abhängigkeit von der jeweiligen kalterstarrenden Masse mit Blick auf die zu erfüllenden Aufgaben, also insbesondere im Verarbeitungsprozeß der kalterstarrenden Massenicht nicht zu unerwünschten Verunreinigungen führt, in üblicher Art und Weise auswählbar sind. Der Verbund aus der Schicht bestehend aus einer Kunststoffmasse und der kalterstarrenden Masse gemeinsam aufschmelzbar ist, ohne das diese Schicht unerwünschte Verunreinigungen (Cracking) verursacht. Wobei natürlich auch Kostenaspekte ein Auswahlkriterium bezüglich möglichst hoher Effizienz darstellen. Beispielsweise seien Kunststoffe genannt, wie Polyolefin, vorzugsweise Polyvinylchlorid, Vinylacetat und / oder einem Acrylsäureester bzw. deren Copolymerisaten.Plastic masses are in the sense of Invention known plastics or plastic mixtures, the dependent of the respective cold-setting mass with a view to the tasks to be performed, in particular in the processing of the cold-stiff mass not too undesirable Impurities, in more usual Selectable way are. The composite of the layer consisting of a plastic mass and the cold-setting mass can be melted together without that this layer is undesirable Causes contamination (cracking). Of course, too Cost aspects represent a selection criterion with regard to the highest possible efficiency. For example, plastics such as polyolefin are preferred Polyvinyl chloride, vinyl acetate and / or an acrylic acid ester or their copolymers.
Die Unteransprüche haben vorteilhafte Weiterbildungen der Erfindung zum Inhalt.The subclaims have advantageous developments the content of the invention.
Bezüglich einer hohen Effizienz der Herstellung der erfindungsgemäßen Verpackung und umweltverträglicher Weiterbehandlung der abgetrennten äußeren Schicht ist eine Verpackung, welche zweischichtig aufgebaut ist, besonders bevorzugt.Regarding high efficiency the production of the packaging according to the invention and more environmentally friendly Further treatment of the separated outer layer is packaging, which is constructed in two layers, particularly preferred.
Außerdem ist bevorzugt, dass die beiden Schichten nur teilweise miteinander verbunden sind, besonders bevorzugt auf weniger als 1% der Fläche, mit welcher diese sich berühren. Damit wird ein besonders einfaches Ablösen der beiden Schichten erreicht, d. h. insbesondere sind nur geringe Kräfte diesbezüglich aufzuwenden.It is also preferred that the two layers are only partially connected to each other, especially preferably on less than 1% of the area with which it covers touch. A particularly simple detachment of the two layers is thus achieved, d. H. in particular, only slight forces are to be applied in this regard.
Weiter Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der Beschreibung einer bevorzugten Ausführungsform, wobei die Erfindung nicht auf diese beschränkt ist.Further details, features and Advantages of the invention result from the description of a preferred one embodiment, the invention is not limited to these.
Die Verpackung besteht aus zwei Schichten, wobei die außenliegende Schicht 1 aus einem 100 g/m2 schweren Recyclingpapier und die andere Schicht 2 aus einer 10 μm PE-HD Folie besteht. Der lösbare Verbund wurde mittels einer üblichen Rasterwalze hergestellt. Damit wurde erreicht, dass die beiden Schichten 1 und 2 nur mit ca. 0,5 % der Fläche, mit welcher diese sich berühren, lösbar verbunden sind. Damit wird erreicht, dass sich die Schicht 1 vollständig, d.h. rückstandsfrei, ablösen läßt und einer umweltschonenden Verwerfung zugeführt werden kann.The packaging consists of two layers, whereby the outer layer 1 consists of 100 g / m2 recycled paper and the other layer 2 consists of a 10 μm PE-HD film. The detachable composite was produced using a conventional anilox roller. It was thus achieved that the two layers 1 and 2 are releasably connected to only about 0.5% of the area with which they touch. This ensures that layer 1 can be removed completely, ie free of residues, and can be fed to an environmentally friendly warp can.
Der Schmelzkleber 3, hier ein Schmelzkleber mit der Handelsbezeichnung MÖKO-Therm S2002 – PET, wird in bekannter Art und Weise bei einer Temperatur von ca. 140°C in die Verpackung gefüllt. Diese Temperatur liegt etwa 10 K unter der Temperatur des Schmelzpunktes der PE-HD Folie (Schicht 2), so dass gewährleistet ist, dass auch nach einer mehrstündigen Abkühlphase keine unlösbare Verbindung zur Schicht 1 entstehen kann.The hot melt adhesive 3, here a hot melt adhesive with the trade name MÖKO-Therm S2002 - PET in a known manner at a temperature of about 140 ° C in the Packaging filled. This temperature is about 10 K below the temperature of the melting point the PE-HD film (layer 2), so that it is guaranteed that even after one of several hours cooling phase not an impossible one Connection to layer 1 can arise.
Die Verarbeitungstemperatur des Schmelzklebers 3 beträgt ca. 150°C bis 170°C. Bei dieser Verarbeitungstemperatur, die unterhalb der kritischen Temperatur der Folie (Schicht 2) von ca. 182°C liegt, ist eine Verkrackung auszuschließen.The processing temperature of the hot melt adhesive 3 is approx. 150 ° C up to 170 ° C. At this processing temperature, which is below the critical temperature the film (layer 2) of approx. 182 ° C cracking must be excluded.
