Definitions
- the invention relates to a film packaging, in particular for bulk material, which has formed by folding a film front surfaces and gussets and is closed by a bottom seam and a top seam.
- the film is provided with a weakening line for opening the package, along which a head-side packaging section is separable. After opening the packaging, one of the two lateral folds can be used as a chute, while an area of the packaging adjacent to the pouring opening remains closed on the upper side.
- a foil package with the features described is out WO 2005/007528 A1 known.
- the film packaging is produced from a prefabricated film bag, which is open at the top and filled in a bag filling system from above and then sealed with a transverse sealing seam which extends over the entire bag width.
- the weakening line extends parallel to the head end over the entire width of the film bag.
- a second transverse sealing seam is necessary below the weakening line, which is applied after filling the film packaging in the bag filling system and extends only over a partial width of the bag.
- the application of different length transverse sealing seams requires customized sealing tools. This is considered a disadvantage in practice, since conversions must be made to the filling system.
- the invention has for its object to provide a film packaging, which can be closed and completed after their filling in a filling with sealing tools that extend over the entire bag width.
- a release layer is arranged from a non-firmly sealable material and that about the entire width of the package extends a transverse sealing seam which is laid over the region of the film provided with the separating layer and firmly connects the two front surfaces and the inner surface of the other side fold with the respectively adjacent front surface only outside this region.
- Non-sealable materials include non-sealable materials and thermally sealable materials which, when thermally sealed, form peelable seal seams of low strength which can be purposefully separated by hand without destroying the film.
- the separating layer prevents a firm thermal welding of the foil surfaces in the area of the later pouring opening and ensures the function of this area without the length of the transverse sealing seam having to be adapted accordingly. For this reason, identical sealing tools can be used in the filling installation in order, on the one hand, to apply the top seal seam and, furthermore, to produce the sealing seam which closes a partial area of the packaging on the top side after opening the package.
- identical sealing tools can be used in the filling installation in order, on the one hand, to apply the top seal seam and, furthermore, to produce the sealing seam which closes a partial area of the packaging on the top side after opening the package.
- An embodiment of the invention provides that at least one two-layer film strip is attached to the packaging inside of the film packaging having a sealable layer connected to the inner surface of the package and a layer of a non-firmly sealable material forming the release layer.
- the film strip consists for example of a composite material with a sealable layer of a polyolefin and a release layer of a non-sealable material, for example polyester.
- the foil strip can be closed annularly.
- the Separating layer of a peelable layer so that the attached to opposite wall surfaces of the packaging portions of the film strip are superimposed and adhere to each other before the first use of the packaging by contact of the peelable layers.
- the peelable layer can consist of an exfoliating sealing wax or of a laminated foil which has corresponding peeligerishities.
- the peel layer may in particular be a polyethylene layer containing polybutene.
- the connection between the peelable layers can be easily released by hand. The connection can ensure the tightness of the bag even if the line of weakness consists of a perforation.
- the film strip is secured below the weakening line on the inside of the package and extends into an area above the line of weakness without being connected to the inside of the package above the line of weakness. After opening the package, the film strip then forms an upwardly projecting chute, which facilitates the pouring of the contents.
- an alternative embodiment of the invention provides that the separating layer consists of a release varnish applied to the film, which is not sealable and prevents through welding. If the film package is opened by severing the header, an upwardly projecting chute may be realized by having the line of weakness in the region of the film provided with the release coating having a corresponding contour, i. H. a contour that simulates an upwardly projecting chute.
- a further improvement in the function of the film packaging can be achieved by arranging a closing meeting on the inside of the packaging in the region of the separating layer, which is fastened to the film below the weakening line and with a free end above the line of weakness ends.
- the free end of the closure strip can be fastened to the outside of the packaging after the packaging has been opened - the pouring opening in cross-section.
- Adhesive strips or strips of a Kiett closure come into consideration as closure strips.
- the invention furthermore relates to a flat foil pouch according to claim 10 for use in a bag filling installation, in which the foil pouch can be filled and closed with transverse sealing seams which extend over the entire width of the pouch to a foil packaging having the features described above.

- the film is provided with a weakening line 5 for opening the package, which extends parallel to the top seam 4 over the entire bag width and also the side folds 2.
- the weakening line 5 may be a perforation or, if greater impermeability is required, a laser seam penetrating only one layer of the usually multilayer film.
- a head-side packaging section 6 is separable, wherein the tearing is facilitated by a finger lift 7 in one of the gussets 2. After opening the packaging, one of the two lateral folds can be used as a chute, while an area of the packaging adjacent to the pouring opening 8 remains closed on the upper side.
- a separating layer 9 made of a non-firmly sealable material is arranged in a region which forms the pouring opening 8 after opening the packaging.
- Parallel to the top seam 4 extends over the entire width of the package, a transverse seam 10, which is placed over the provided with the release layer 9 region of the film and only outside this area, the two front surfaces 1 and the inner surface of the other side fold 2 'with the respectively adjacent Front surface 1, 1 'firmly connects ( Fig. 2 ).

Abstract
Description
Die Erfindung betrifft eine Folienverpackung, insbesondere für Schüttgut, die durch Falten einer Folie gebildete Frontflächen und Seitenfalten aufweist und durch eine Bodennaht sowie eine Kopfnaht verschlossen ist. Die Folie ist mit einer Schwächungslinie zum Öffnen der Verpackung versehen, entlang der ein kopfseitiger Verpackungsabschnitt abtrennbar ist. Nach dem Öffnen der Verpackung ist eine der beiden Seitenfalten als Schütte nutzbar, während ein an die Schüttöffnung angrenzender Bereich der Verpackung oberseitig verschlossen bleibt. Eine Folienverpackung mit den beschriebenen Merkmalen ist aus
Die Folienverpackung wird aus einem vorkonfektionierten Folienbeutel hergestellt, der oben offen ist und in einer Beutelbefüllanlage von oben befüllt sowie anschließend mit einer Quersiegelnaht, die sich über die gesamte Beutelbreite erstreckt, verschlossen wird. Bei einer aus
Der Erfindung liegt die Aufgabe zugrunde, eine Folienverpackung anzugeben, die nach ihrer Befüllung in einer Befüllanlage mit Siegelwerkzeugen, die sich über die gesamte Beutelbreite erstrecken, verschlossen und fertig gestellt werden kann.The invention has for its object to provide a film packaging, which can be closed and completed after their filling in a filling with sealing tools that extend over the entire bag width.
Ausgehend von einer Folienverpackung mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass an der Verpackungsinnenseite der Folie in einem Bereich, der nach dem Öffnen der Verpackung die Schüttöffnung bildet, eine Trennschicht aus einem nicht fest versiegelbaren Material angeordnet ist und dass sich über die gesamte Breite der Verpackung eine Quersiegelnaht erstreckt, die über den mit der Trennschicht versehenen Bereich der Folie gelegt ist und lediglich außerhalb dieses Bereiches die beiden Frontflächen sowie die Innenfläche der anderen Seitenfalte mit der jeweils benachbarten Frontfläche fest verbindet. Unter nicht fest versiegelbare Materialien fallen nicht siegelfähige Materialien und thermisch siegelfähige Materialien, die beim thermischen Siegeln peelfähige Siegelnähte geringer Festigkeit bilden, welche bestimmungsgemäß von Hand ohne Zerstörung der Folie getrennt werden können. Die Trennschicht unterbindet eine feste thermische Verschweißung der Folienflächen im Bereich der späteren Schüttöffnung und stellt die Funktion dieses Bereiches sicher, ohne dass die Länge der Quersiegelnaht entsprechend angepasst werden muss. Daher können in der Befüllanlage gleiche Siegelwerkzeuge verwendet werden, um einerseits die Kopfsiegelnaht anzubringen und ferner diejenige Siegelnaht zu erzeugen, die nach dem Öffnen der Verpackung einen Teilbereich der Verpackung oberseitig verschließt. Es ergeben sich mehrere Möglichkeiten für die Ausgestaltung und Anordnung der Trennschicht.Starting from a film package with the features described above, the object is achieved in that on the packaging inside of the film in a region which forms the pour opening after opening the package, a release layer is arranged from a non-firmly sealable material and that about the entire width of the package extends a transverse sealing seam which is laid over the region of the film provided with the separating layer and firmly connects the two front surfaces and the inner surface of the other side fold with the respectively adjacent front surface only outside this region. Non-sealable materials include non-sealable materials and thermally sealable materials which, when thermally sealed, form peelable seal seams of low strength which can be purposefully separated by hand without destroying the film. The separating layer prevents a firm thermal welding of the foil surfaces in the area of the later pouring opening and ensures the function of this area without the length of the transverse sealing seam having to be adapted accordingly. For this reason, identical sealing tools can be used in the filling installation in order, on the one hand, to apply the top seal seam and, furthermore, to produce the sealing seam which closes a partial area of the packaging on the top side after opening the package. There are several possibilities for the design and arrangement of the separation layer.
Eine erfindungsgemäße Ausgestaltung sieht vor, dass an der Verpackungsinnenseite der Folieverpackung ein mindestens zweischichtiger Folienstreifen befestigt ist, der eine mit der Innenfläche der Verpackung verbundene siegelfähige Schicht und eine die Trennschicht bildende Schicht aus einem nicht fest versiegelbaren Material aufweist. Der Folienstreifen besteht beispielsweise aus einem Verbundmaterial mit einer siegelfähigen Schicht aus einem Polyolefin sowie einer Trennschicht aus einem nicht siegelfähigen Material, z B. Polyester. Der Folienstreifen kann ringförmig geschlossen sein. Ferner kann die Trennschicht aus einer peelfähigen Schicht bestehen, so dass die an gegenüberliegenden Wandflächen der Verpackung angebrachten Abschnitte des Folienstreifens aufeinander liegen und vor dem erstmaligen Gebrauch der Verpackung durch Kontakt der peelfähigen Schichten aufeinander haften. Die peelfähige Schicht kann aus einem peelenden Siegellack oder aus einer aufkaschierten Folie, die entsprechende Peeleigerischaften aufweist, bestehen. Die Peelschicht kann insbesondere eine Polyethylenschicht sein, die Polybuten enthält. Die Verbindung zwischen den peelfähigen Schichten lässt sich leicht von Hand lösen. Die Verbindung kann die Dichtigkeit des Beutels auch dann gewährleisten, wenn die Schwächungslinie aus einer Perforation besteht.An embodiment of the invention provides that at least one two-layer film strip is attached to the packaging inside of the film packaging having a sealable layer connected to the inner surface of the package and a layer of a non-firmly sealable material forming the release layer. The film strip consists for example of a composite material with a sealable layer of a polyolefin and a release layer of a non-sealable material, for example polyester. The foil strip can be closed annularly. Furthermore, the Separating layer of a peelable layer, so that the attached to opposite wall surfaces of the packaging portions of the film strip are superimposed and adhere to each other before the first use of the packaging by contact of the peelable layers. The peelable layer can consist of an exfoliating sealing wax or of a laminated foil which has corresponding peeligerishities. The peel layer may in particular be a polyethylene layer containing polybutene. The connection between the peelable layers can be easily released by hand. The connection can ensure the tightness of the bag even if the line of weakness consists of a perforation.
Vorzugsweise ist der Folienstreifen unterhalb der Schwächungslinie an der Innenseite der Verpackung befestigt und erstreckt sich bis in einen Bereich oberhalb der Schwächungslinie, ohne mit der Innenseite der Verpackung oberhalb der Schwächungslinie verbunden zu sein. Nach dem Öffnen der Verpackung bildet der Folienstreifen dann eine nach oben vorstehende Schütte, die das Ausschütten des Füllguts erleichtert.Preferably, the film strip is secured below the weakening line on the inside of the package and extends into an area above the line of weakness without being connected to the inside of the package above the line of weakness. After opening the package, the film strip then forms an upwardly projecting chute, which facilitates the pouring of the contents.
Eine alternative Ausgestaltung der Erfindung sieht vor, dass die Trennschicht aus einem auf die Folie aufgebrachten Trennlack besteht, der nicht siegelfähig ist und das Durchschweißen verhindert. Wenn die Folienverpackung durch Abtrennen des Kopfstückes geöffnet wird, kann eine nach oben vorstehende Schütte dadurch realisiert werden, dass die Schwächungslinie in dem mit dem Trennlack versehenen Bereich der Folie eine entsprechende Kontur aufweist, d. h. eine Kontur, die eine nach oben vorstehende Schütte nachbildet.An alternative embodiment of the invention provides that the separating layer consists of a release varnish applied to the film, which is not sealable and prevents through welding. If the film package is opened by severing the header, an upwardly projecting chute may be realized by having the line of weakness in the region of the film provided with the release coating having a corresponding contour, i. H. a contour that simulates an upwardly projecting chute.
Für alle zuvor beschriebenen Ausgestaltungen lässt sich eine weitere Funktionsverbesserung der Folienverpackung erreichen, indem an der Innenseite der Verpackung im Bereich der Trennschicht ein Verschlussstreffen angeordnet wird, der unterhalb der Schwächungslinie an der Folie befestigt ist und mit einem freien Ende oberhalb der Schwächungslinie endet. Das freie Ende des Verschlussstreifens ist nach dem Öffnen der Verpackung - die Schüttöffnung dabei übergreifend - an der Verpackungsaußenseite befestigbar. Hierbei wird der obere Rand der Schüttöffnung umgefaltet und dadurch auch verschlossen. Als Verschlussstreifen kommen Klebestreifen oder Streifen eines Kiettverschlusses in Betracht.For all embodiments described above, a further improvement in the function of the film packaging can be achieved by arranging a closing meeting on the inside of the packaging in the region of the separating layer, which is fastened to the film below the weakening line and with a free end above the line of weakness ends. The free end of the closure strip can be fastened to the outside of the packaging after the packaging has been opened - the pouring opening in cross-section. Here, the upper edge of the pouring opening is folded over and thereby closed. Adhesive strips or strips of a Kiett closure come into consideration as closure strips.
Gegenstand der Erfindung ist ferner ein flachliegender Folienbeutel nach Anspruch 10 zur Verwendung in einer Beutelbefüllanlage, in der der Folienbeutel befüllbar und mit Quersiegelnähten, die sich über die gesamte Beutelbreite erstrecken, zu einer Folienverpackung mit den zuvor beschriebenen Merkmalen schließbar ist.
