VerbundfolieComposite film
Gegenstand vorliegender Erfindung ist eine aus mindestens einer Folie aus nicht siegelbarem Material und mindestens einer Folie aus siegelbarem Material bestehende Verbundfolie, deren Aussenseite durch eine Folie aus nicht siegelbarem Material gebildet wird, gekennzeichnet durch von der Aussenseite bis zu einer Folie aus siegelbarem Material reichende Durchbrechungen.The present invention is one made of at least one film made of non-sealable material and at least A composite film consisting of a film made of sealable material, the outside of which is covered by a film made of non-sealable material Material is formed, characterized by from the outside to a film of sealable material reaching breakthroughs.
Solche Folien finden besonders in der Verpackungsindustrie Anwendung und dienen vor allem zur Herstellung von Behältern, wie Säcken, Beuteln, usw. Im Zuge der HerstellungSuch films are particularly found in the packaging industry Application and are mainly used to manufacture containers such as sacks, bags, etc. In the course of manufacture

solcher Behälter besteht sehr oft das Bedürfnis, auch die aus nicht siegelbarem Material bestehende Aussenseite Mit irgendwelchen anderen Behälterteilen aus siegelbarem Material verbinden bzw. heissiegeln zu können. Ein solches Problem stellt sich beispielsweise bei der Herstellung von aus einem Stück hergestellten, faltbaren Standbeuteln, bei denen in gefaltetem Zustand der Boden W~förmig ausgestaltet ist und wo zur Verbesserung der Standfestigkeit ein Bedürfnis besteht, auch im Räume des. gefalteten Bodens die benachbarten Seitenwände unmittelbar miteinander verbinden zu können. Bis heute hat man sich damit beholfen, solche Zwischenteile wie der erwähnte Boden im Zuge der Eeutelherstellung zu perforieren. Diese Lösung hat aber den Nachteil, dass in den Beutelfabrikationsprozess, der üblicherweise nur FaIt- und Siegelvorgänge umfasst, noch einen artfremden Perforationsvorgang miteinbeziehen zu müssen, was zu nachteiligen Komplikationen führte.There is very often a need for such a container, including the Outside made of non-sealable material With any other container parts made of sealable material To be able to connect or heat seal material. Such a problem arises, for example, in manufacture of one-piece, foldable stand-up pouches, in which the bottom is W-shaped when folded is and where there is a need to improve stability, also in the area of the folded floor to be able to connect the adjacent side walls directly to one another. To this day one has managed to to perforate such intermediate parts as the bottom mentioned in the course of the bag manufacture. But this solution has the disadvantage that in the bag manufacturing process, which usually only includes folding and sealing processes, still having to include an alien perforation process, which led to disadvantageous complications.
Der vorliegenden Erfindung lag die Aufgabe zugrunde, durch eine besondere Ausgestaltung der Verbundfolie den Perforationsvorgang bei der Beutelherstellung überflüssig zu machen .The present invention was based on the object by a special design of the composite film to make the perforation process in the bag production superfluous .
Dies wird erfindungsgemäss durch von der Aussenseite bis zu einer Folie aus siegelbarem Material reichende Durchbrechungen erreicht.According to the invention, this is done from the outside to Reached breakthroughs to form a film made of sealable material.
In der Zeichnung sind drei Ausführungsbeispiele der erfindungsgemässen Folie je im Schnitt dargestellt.In the drawing are three exemplary embodiments of the invention Slide shown in section.
Pig. 1 zeigt eine Verbundfolie, welche aus einer Trägerfolie 1 aus nicht siegelbarem Material, wie beispielsweise Cellglas, Papier oder einer Alufolie, besteht, welche auf ihrer Unterseite mit einer Folie 2 aus thermoplastischemPig. 1 shows a composite film which consists of a carrier film 1 made of non-sealable material, such as cell glass, paper or aluminum foil, which on their underside with a film 2 made of thermoplastic

Material, wie Polyäthylen, Polypropylen, ein Copolymerisat uov/. verbunden ist.Material such as polyethylene, polypropylene, a copolymer uov /. connected is.
Die Trägerfolie 1 ist nun mit einer Reihe von Perforatio7 nen 3 versehen, welche bis zur Folie 2 aus dem siegelbaren Material reichen, so dass dieses Material auch von der Seite der Trägerfolie her zugänglich ist und die Möglichkeit besteht, diese Folie auf der durch die Trägerfolie gebildeten Aussenseite mit irgendwelchen Teilen, bspw. eines Beutels aus siegelbarem Material heisszusiegeln.The carrier film 1 is now provided with a number of perforations 3, which extend to the film 2 from the sealable Sufficient material so that this material is also accessible from the side of the carrier film and there is the possibility of this film on the outside formed by the carrier film with any parts, for example one Heat sealable bag made of sealable material.
Die Verbundfolie nach Fig. 2 besteht aus einer Aussenfolie *J aus nichtsiegelbarem Material wie z.B. Polyesterfilm, welche mittels einer siegelbaren Zwischenfolie 5 aus Polypropylen mit einer Aluminium-Folie 6 kaschiert ist, welche letzte schliesslich auf ihrer Innenseite eine Folie 7 aus Polypropylen trägt. Auch hier sind zum gleichen Zwecke in der Aussenfolie 1I aus nicht siegelbarem Material Durchbrechungen 3 vorgesehen, welche bis zur Zwischenfolie 5 aus '. Polypropylen reichen, so dass auch hier dieses siegelbare Material von der durch die Polyester-Aussenfolie gebildeten Aussenseite her zugänglich ist und in bereits erwähnter Weise eine Siegelverbindung auch auf dieser Seite der Verbundfolie hergestellt werden kann.The composite film according to FIG. 2 consists of an outer film * J made of non-sealable material such as polyester film, which is laminated with an aluminum film 6 by means of a sealable intermediate film 5 made of polypropylene, the last of which finally has a film 7 made of polypropylene on its inside. Again, for the same purpose in the outer film 1 I provided from non-sealable material through holes 3, which up to the intermediate foil 5 of '. Polypropylene is sufficient, so that here too this sealable material is accessible from the outside formed by the polyester outer film and a sealed connection can also be produced on this side of the composite film in the manner already mentioned.
Die Verbundfolie gemäss Fig. 3 besteht aus einer Aussen- und einer Innenfolie 8 bzw. 9 aus nicht siegelbarem Material, welche durch eine Zwischenfolie 10 aus einem siegelbaren Material miteinander verbunden sind. Diese an sich nicht siegelbare Verbundfolie kann nun durch die bis zur Zwischenfolie 10 reichende Durchbrechungen 3 stellenvreise siegelbar gemacht werden.The composite film according to FIG. 3 consists of an outer and an inner film 8 or 9 made of non-sealable material, which is surrounded by an intermediate film 10 made of a sealable material are connected to each other. This composite film, which cannot be sealed per se, can now pass through to the intermediate film 10 reaching breakthroughs 3 places can be made sealable.

Durch die Verwendung der beschriebenen Verbundfolien gelingt es, Heissiegclungen auch auf der Seite einer aus nicht siegelbarem Material bestehenden Aussenseite vornehmen zu können .und somit die Herstellung von Erzeugnissen aus solchen Verbundfolien, wie z.B. Beutel, entscheidend zu vereinfachen.By using the composite films described, it is possible to produce heat seals on one side as well to be able to make non-sealable material on the outside and thus the manufacture of products made of such composite films, such as bags, to simplify decisively.
