Description

Die Erfindung betrifft eine wiederverschließbare Schlauchtbeutelpackung bestehend aus einer feuchtigkeitsdichten Hülle, die aus einem flächigen, faltbaren Verpackungsmaterial gebildet ist, von dem zwei streifenförmige Randzonen an ihren Innenseiten in einem Verbindungsbereich durch eine peelfähige Kaltsiegelung miteinander verbunden sind, und wobei die nach außen zu liegen kommende Randzone den Verbindungsbereich in Form eines streifenförmigen Randbereiches überragt.The invention relates to a reclosable tubular bag pack consisting of a moisture-proof shell made of a flat, foldable packaging material is formed, two of which are strip-shaped Edge zones on their inner sides in a connection area by a peelable cold sealing are interconnected, and the after edge zone coming to the outside form the connection area of a strip-like edge area.

Die Erfindung betrifft ferner die Verwendung dieser Schlauchbeutelpackung zum Verpacken von feuchtigkeitsempfindlichem Packgut, vorzugsweise Papier für Tintenstrahldrucker.The invention further relates to the use of this tubular bag pack for packaging moisture-sensitive packaged goods, preferably paper for inkjet printers.

Insbesondere beim Verpacken von feuchtigkeitsempfindlichem Packgut ist man von bekannten Einwickel- oder Envelope-Packungen auf Packungen in Form von Beuteln oder Schläuchen übergegangen, bei denen die Randbereiche des Verpackungsmaterials durch Siegelnähte miteinander verbunden sind. Durch diese Siegelnähte ist es gewährleistet, daß das Packgut luft- und feuchtigkeitsdicht abgepackt ist. Diese vorteilhafte Eigenschaft wird durch die luft- und feuchtigkeitsdichten Siegelnähte hervorgerufen.Especially when packing moisture-sensitive packaged goods one of known wrapping or envelope packs on packs in the form of bags or tubes, in which the Edge areas of the packaging material with sealed seams are connected. These sealed seams ensure that Packaged goods are packed airtight and moisture-proof. This beneficial Property is due to the air and moisture-tight sealing seams evoked.

Im Falle von Siegelrand-Flachbeutelpackungen sind drei seitliche Siegelnähte vorgesehen, während anstelle der vierten Siegelnaht eine Öffnungshilfe in Form von perforierten Hartgummibändern vorgesehen ist. Durch die Perforation ist einerseits die Luftdichtheit der Packung und andererseits deren Wiederverschließbarkeit gewährleistet. Diese Siegelrand-Flachbeutelpackungen eignen sich nicht nur für das Verpacken von Nahrungsmitteln sondern auch für das Verpacken von feuchtigkeitsempfindlichen, technischen Materialien, wie beispielsweise Tintenstrahldruckerpapier. Dieses wird vermehrt nicht nur zum Ausdrucken von gespeicherten Computertexten sondern auch für graphische Darstellungen sowie für Fotografien verwendet. Kommt das Papier jedoch mit Feuchtigkeit in Berührung, so ändert sich dessen Form maßgeblich und das erzeugte Druck- oder Fotografiebild kann nicht mehr dimensionsgerecht wiedergegeben werden.In the case of sealed edge flat packs, there are three side packs Sealing seams are provided, while one instead of the fourth sealing seam Opening aid in the form of perforated hard rubber bands is provided. Due to the perforation, the airtightness of the pack and on the other hand, their resealability is guaranteed. This Sealed-edge flat bag packs are not only suitable for packaging of food but also for packaging moisture-sensitive, technical materials such as Inkjet printer paper. This is not only increasing Printing of stored computer texts but also for graphic representations and used for photographs. Does that come However, paper in contact with moisture changes its shape decisive and the printed or photographic image generated can no longer are reproduced dimensionally.

Obzwar die vorgenannten Siegelrand-Flachbeutelpackungen feuchtigkeitsbeständig und auch wiederverschließbar sind, ist ihre Herstellung relativ aufwendig, da die vorgenannte Öffnungshilfe nur mit hohem Maschinenaufwand paßgenau im Randbereich angebracht werden kann. Ferner ist die Siegelrand-Flachbeutelpackung für das Verpacken von Tintenstrahldruckerpapier nicht sehr verbraucherfreundlich, da bei der Entnahme von einzelnen Papieren diese regelmäßig zerknittert werden und dadurch die geforderte Dimensionsstabilität für den präzisen Aufdruck nicht mehr erfüllen.Although the aforementioned sealed edge flat bag packs are moisture-resistant and are also resealable is their manufacture relatively complex, since the above opening aid only with high Machine effort can be attached precisely in the edge area. Furthermore, the sealed-edge flat bag pack is for packaging Inkjet printer paper is not very consumer-friendly, since the Removal of individual papers these are regularly crumpled and thereby the required dimensional stability for the precise printing no longer meet.

Aufgabe der vorliegenden Erfindung ist es daher, wiederverschließbare und feuchtigkeitsdichte Packungen anzugeben, die leicht herstellbar und gleichzeitig verbraucherfreundlich sind.The object of the present invention is therefore to be resealable and specify moisture-tight packs that are easy to manufacture and are consumer-friendly at the same time.

Vorteilhafterweise besteht das für die Schlauchbeutelpackung verwendete Verpackungsmaterial aus einem Mehrschichtverbund, welcher an seiner Außenseite eine Kunststoff-Folie, vorzugsweise eine OPP-Folie aufweist, die an ihrer Unterseite mit einer Dauerkleberbeschichtung versehen ist. Für die Aus- oder Durchstanzungen werden vorteilhafterweise in deren Bereich sämtliche Mehrschichtverbundlagen mit Ausnahme der Kunststoff-Folie und der vorgenannten Dauerkleberbeschichtung entfernt. Dadurch wird im Bereich der Aus- oder Durchstanzungen vorteilhafterweise die Wiederverschließbarkeit der Schlauchbeutelpackung bewirkt, bedingt durch die an der Unterseite der Kunststoff-Folie, vorzugsweise der OPP-Folie, angebrachte Dauerkleberbeschichtung. Diese Dauerkleberbeschichtung dient auch gleichzeitig zum Verbinden der unterschiedlichen Schichten im Verpackungsmaterialverbund.This is advantageously used for the tubular bag pack Packaging material from a multi-layer composite, which on its Has a plastic film on the outside, preferably an OPP film, which is provided with a permanent adhesive coating on its underside. For the punched or punched holes are advantageously in their area all multi-layer composite layers with the exception of the plastic film and the aforementioned permanent adhesive coating removed. This will in Area of punching or punching advantageously the Resealability of the tubular bag pack causes, conditionally through the on the underside of the plastic film, preferably the OPP film, applied permanent adhesive coating. This permanent adhesive coating also serves to connect the different ones Layers in the packaging material network.

Eine weitere Variante der erfindungsgemäßen Schlauchbeutelpackung besteht darin, daß im Bereich der Aus- oder Durchstanzungen sämtliche Verpackungsmateriallagen entfernt sind, und zum Wiederverschließen ein Klebefilm im Bereich dieser Aus- oder Durchstanzungen vorgesehen ist. Another variant of the tubular bag pack according to the invention is that all in the area of punching or punching Packing material layers are removed, and to reclose Adhesive film is provided in the area of this punching or punching.

Figur 1 zeigt die erfindungsgemäße Schlauchtbeutelpackung 1, wobei man die in einem streifenförmigen Verbindungsbereich 4 durch eine Kaltsiegelung 8 miteinander verbundenen streifenförmigen Randzonen 2 und 3 erkennt. Diese werden als sogenannte "Finne" auf die Oberfläche der Packungshülle umgeschlagen. Die nach außen zu liegen kommende Randzone 2 ist dabei breiter als die Randzone 3, so daß zwischen dem Rand 6 und dem Rand 7 der unten liegenden Randzone 3 ein streifenförmiger Bereich 5 verbleibt, der über die unten liegenden Randzone 3 hinausragt. Innerhalb dieses streifenförmigen Bereiches 5 sind mehrere Durchstanzungen 9 und 10 vorgesehen. Diese Durchstanzungen können entweder bereits in der angelieferten Verpackungsmaterialbahn vorhanden sein oder an der Verpackungsmaschine kurz vor der Bildung des Verpackungsmaterialschlauches eingestanzt werden. In jedem Fall sind die Aus- oder Durchstanzungen durch Druckermarken (nicht dargestellt) gekennzeichnet, so daß sie von einem in der Aus- oder Durchstanzvorrichtung angebrachten Sensor ermittelt werden können. Dadurch ist ein paßgenaues Aus- oder Durchstanzen innerhalb des Bereiches 5 möglich.Figure 1 shows the tube bag package 1 according to the invention, wherein one which in a strip-shaped connection area 4 by a Cold sealing 8 interconnected strip-shaped edge zones 2 and 3 recognizes. These are called "fins" on the surface of the Cover wrapped. The one coming to the outside Edge zone 2 is wider than edge zone 3, so that between the Edge 6 and the edge 7 of the bottom edge zone 3 Strip-shaped area 5 remains, which is above the one below Edge zone 3 protrudes. Are within this strip-shaped area 5 several punchings 9 and 10 are provided. These punchings can either already be delivered in the packaging material web be present or on the packaging machine shortly before the formation of the Packaging material hose are punched. In any case, they are Punching or punching through printer brands (not shown) marked so that it is from one in the out or Punching device attached sensor can be determined. This is a precise punching or punching within the Area 5 possible.

Beim Öffnen der Schlauchbeutelpackung 1 wird der streifenförmige Bereich 5 in Richtung des Pfeiles 12 gezogen, wobei durch die aufgewandte Kraft der Randbereich 2 von der Kaltkleberbeschichtung 8 abgeschält bzw. gepeelt werden kann und dadurch dem Verbraucher in einfacher Weise der Zugriff zum Packgut möglich ist.When you open the tubular bag pack 1, the strip-like Area 5 drawn in the direction of arrow 12, with the applied force of the edge area 2 by the cold adhesive coating 8 can be peeled off and peeled and thereby the consumer in simple access to the packaged goods is possible.

Das Wiederverschließen der Schlauchbeutelpackung 1 ist durch eine Dauerkleberbeschichtung 15, 19 möglich. Dazu stehen zwei erfindungemäße Varianten gemäß Figur 2 und Figur 3 zur Verfügung.The reclosure of the tubular bag pack 1 is by a Permanent adhesive coating 15, 19 possible. There are two Variants according to the invention according to FIG. 2 and FIG. 3 are available.

In Figur 2 wird im Bereich Aus- oder Durchstanzung 9 mittels einer an der Kunststoff-Folie, vorzugsweise OPP-Folie 14 des Verpackungsmehrschichtverbundes 13 vorgesehenen Dauerkleberbeschichtung 15 die Wiederverschließbarkeit der Schlauchbeutelpackung 1 erzeugt. Diese dient nicht nur zur klebenden Haftung auf der Kunststoff-Folie 14 der Materiallage des unteren Randbereiches 3 im Ausstanzbereich 9 für das Wiederverschließen, sondern auch zum Verkleben der Materiallagen 14 und 16 im Verpackungsmaterialverbund 13. In FIG. 2, punching or punching 9 is carried out in the area by means of a Plastic film, preferably OPP film 14 of the packaging multilayer composite 13 provided permanent adhesive coating 15 the Resealability of the tubular bag pack 1 is generated. This serves not only for adhesive adhesion to the plastic film 14 Material layer of the lower edge area 3 in the punched area 9 for the Reseal, but also for gluing the material layers 14 and 16 in the packaging material group 13.

Zur Herstellung dieses dreischichtigen Materialverbundes 13 verwendet man beispielsweise von der Verbundseite von außen nach innen gehend eine etwa 0,015 bis 0,020 mm starke biaxial gereckte Polypropylenfolie (OPP-Folie) 14, eine Dauerkleberbeschichtung 15, welche die OPP-Folie 14 mit einem Aluminium/Papierverbund 16 verbindet. Dieser Aluminium/Papierverbund 16 wird aus einer etwa 0,007 bis 0,009 mm starken gegebenenfalls bedruckten Aluminiumfolie sowie einem Papier mit einer Grammatur von 30-100 g/m2 gebildet. Zur Ausbildung dieses Aluminium/Papierverbundes 16 wird im Profil (nicht dargestellt) eine Kaltkleberbeschichtung auf Latexbasis in einem Ausmaß von etwa 2-7 g/m2 Feststoff verwendet.To produce this three-layer material composite 13, for example, an approximately 0.015 to 0.020 mm thick biaxially stretched polypropylene film (OPP film) 14, a permanent adhesive coating 15, which covers the OPP film 14 with an aluminum / paper composite 16, is used, going from the outside inwards connects. This aluminum / paper composite 16 is formed from an approximately 0.007 to 0.009 mm thick optionally printed aluminum foil and a paper with a grammage of 30-100 g / m 2 . To form this aluminum / paper composite 16, a cold adhesive coating based on latex is used in the profile (not shown) to an extent of about 2-7 g / m 2 solid.

Die Aus- oder Durchstanzungen 9 werden nunmehr mittels Druckermarken (nicht dargestellt) hergestellt, deren Dimensionen auf dem Verpackungsmaterial gekennzeichnet sind, so daß der Aluminium/Papierverbund 16 bis zu der Dauerkleberbeschichtung 15 entfernt werden kann.The punching or punching 9 are now using printer marks (not shown) manufactured, its dimensions on the packaging material are marked so that the aluminum / paper composite 16 to can be removed to the permanent adhesive coating 15.

Beim Wiederverschließen der Packung durch den Verbraucher kommt durch kurzes Andrücken im Bereich der Aus- oder Durchstanzungen 9 die Dauerkleberbeschichtung 15 mit der OPP-Folie 14 der darunterliegenden Randzone 3 in Kontakt. Dadurch erfolgt eine Überbrückung durch die OPP-Folie 14 der darüberliegenden Randzone 2 im Bereich der Aus- oder Durchstanzung 9 einerseits, und andererseits erfolgt eine Verklebung bedingt durch die Dauerkleberbeschichtung 15 mit der darunterliegenden OPP-Folie 14 in diesem Bereich. Durch diese beiden Maßnahmen ist bei der Wiederverschließbarkeit die Feuchtigkeitsdichtheit der Schlauchbeutelpackung gemäß Figur 1, Variante Schnitt II - II gewährleistet.
