- the invention relates to a film packaging for oxygen-sensitive food, which consists of a multi-layer film web and a flap covering an opening flap has according to the preamble of claim 1.
- a film packaging is from the GB 921980 known.
- the film web consists of three layers, which are to be laminated twice in two operations. Apart from the fact that the production of this film web thus extremely expensive and this is therefore expensive, made of such a packaging material bag for oxygen-sensitive food is not usable, so that the scope of this known packaging is very limited. Only if another barrier film is incorporated into the disclosed film web could it possibly also be used for packaging oxygen-sensitive goods. But this would require a further manufacturing and cost.
- the object of the invention is therefore to provide a film packaging for oxygen-sensitive food of the aforementioned type, which is not only easy to produce, but which can also be offered inexpensively.
- the material structure of the film web should be simple and comprise only a few layers, wherein in one of the layers, a barrier layer can be integrated, so that not only a high Operational reliability is given, but the film web can also be used in many ways.
- this is achieved in that the film web is folded on the opposite side of the opening, that a sealable layer of the film webs forms the inside of the film package and is sealed in the two edge regions and that for sealing the closure flap with the barrier layer Location of the film web on this or the flap partially a layer of a heat sealing lacquer is applied.
- the layer of the heat seal lacquer may be flush with the edge of the recessed side of the foil package and cover both of the sealing seams arranged in the edge regions. However, it is also possible to arrange the layer of the heat sealing lacquer at a distance from the edge of the recessed foil packaging and to connect it to the two sealing seams extending in the edge regions.
- the sealable layer of the film web should be formed by a polyethylene layer which acts as a barrier layer of the film web through a polyamide layer, wherein the polyethylene layer should be connected via a bonding agent with the polyamide layer.
- the film web for producing a film packaging for oxygen-sensitive foodstuffs should consist of a polyamide layer which forms the outside of the film packaging and acts as a barrier layer and which forms the inside Polyethylene layer, which are connected to each other by means of a primer or adhesive, and on the outside of the film packaging in the region of the closure flap or applied thereto layer of a heat sealing lacquer.
- a film package according to the invention is formed, then not only a cost-effective production with low manufacturing and material costs is given, but it is also ensured that the film packaging has a high reliability.
- the film web from which the film packaging is made namely, consists of only two layers connected via a bonding agent, of which a layer which forms the inside of the film packaging, with it is sealable, the other layer, however, forms a barrier layer against oxygen.
- the proposed packaging is accordingly, without the need for additional effort, especially versatile for the storage of oxygen-sensitive foods.
- the film web from which the packaging is to be produced in a particularly simple manner, can be produced in only one operation, and disturbances are virtually eliminated. Nevertheless, with the aid of the layer of a heat sealing lacquer provided in the region of the packaging opening, sealing of the closing flap, although it rests on the outer side of the foil web acting as a barrier layer, is also to be accomplished.
- FIGS. 1 to 3 illustrated and denoted by 1 and 1 'film packaging is used to receive oxygen-sensitive food 10 in the interior 2 and consists of a two-ply film web 11, which is composed of a polyamide layer 12 and a polyethylene layer 13. With the aid of a bonding agent 14 is the polyamide layer 12, as in particular the FIG. 5 can be seen, firmly connected to the polyethylene layer 13.
- a correspondingly broadly dimensioned section of the film web 11 is folded around a folded edge 6 and this is sealed on the two longitudinal sides, so that seal seams 17 and 18 form.
- FIG. 2 closes in the film package 1, the layer of heat sealing lacquer 21 directly to the edge of the opening 3, which is formed by offset of the cooperating with the flap 4 side of the film package 1 against the folding edge 5, and is arranged in the form of a continuous strip.
- the layer of heat-sealing lacquer 21st slightly set back relative to the opening 4, so that in the two edge regions, two additional strips 21 'of the layer of heat sealing lacquer 21 are applied, which extend to the edge of the opening 4. In this way, it is also ensured in this embodiment, that in closed film packaging 1 or 1 'no air from the outside can get into the interior 2.
- the film package 1 is to be formed from the film web 11 by folding a section around the two folded edges 5 and 6, by applying the layer of heat sealing lacquer 21 and sealing the superimposed polyethylene layer 13 and the layer of heat sealing lacquer 21 with the closure flap 4 and the polyamide layer 12 ,

Description
Die Erfindung bezieht sich auf eine Folienverpackung für sauerstoffempfindliche Lebensmittel, die aus einer mehrlagigen Folienbahn besteht und eine umschlagbare eine Öffnung abdeckende Verschlussklappe aufweist gemäß dem Oberbegriff des Anspruchs 1. Eine derartige Folienverpackung ist aus der
Aus der
Aufgabe der Erfindung ist es daher, eine Folienverpackung für sauerstoffempfindliche Lebensmittel der vorgenannten Gattung zu schaffen, die nicht nur problemlos herzustellen ist, sondern die auch preisgünstig angeboten werden kann. Vor allem der Materialaufbau der Folienbahn soll einfach sein und nur wenige Lagen umfassen, wobei in einer der Lagen eine Barriereschicht integriert sein kann, so dass nicht nur eine hohe Betriebssicherheit gegeben ist, sondern die Folienbahn auch vielseitig eingesetzt werden kann.The object of the invention is therefore to provide a film packaging for oxygen-sensitive food of the aforementioned type, which is not only easy to produce, but which can also be offered inexpensively. Above all, the material structure of the film web should be simple and comprise only a few layers, wherein in one of the layers, a barrier layer can be integrated, so that not only a high Operational reliability is given, but the film web can also be used in many ways.
Gemäß der Erfindung wird dies dadurch erreicht, dass die Folienbahn auf der der Öffnung gegenüberliegenden Seite gefaltet ist, dass eine miteinander versiegelbare Lage der Folienbahnen die Innenseite der Folienverpackung bildet und in den beiden Randbereichen versiegelt ist und dass zum Versiegeln der Verschlussklappe mit der als Sperrschicht ausgebildeten Lage der Folienbahn auf dieser oder der Verschlussklappe partiell eine Schicht aus einem Heißsiegellack aufgebracht ist.According to the invention, this is achieved in that the film web is folded on the opposite side of the opening, that a sealable layer of the film webs forms the inside of the film package and is sealed in the two edge regions and that for sealing the closure flap with the barrier layer Location of the film web on this or the flap partially a layer of a heat sealing lacquer is applied.
Vorteilhaft ist es, die mit der Verschlussklappe verbindbare Seite der Folienverpackung gegenüber der Faltkante der Verschlussklappe zurückgesetzt auszubilden.It is advantageous to configure the side of the film packaging which can be connected to the closure flap with respect to the folded edge of the closure flap.
Die Schicht des Heißsiegellackes kann bündig mit der Kante der zurückgesetzten Seite der Folienverpackung verlaufen und deren beide in den Randbereichen angeordnete Siegelnähte überdecken. Es ist aber auch möglich, die Schicht des Heißsiegellackes mit Abstand zu der Kante der zurückgesetzten Folienverpackung anzuordnen und an die beiden in den Randbereichen verlaufenden Siegelnähte anzuschließen.The layer of the heat seal lacquer may be flush with the edge of the recessed side of the foil package and cover both of the sealing seams arranged in the edge regions. However, it is also possible to arrange the layer of the heat sealing lacquer at a distance from the edge of the recessed foil packaging and to connect it to the two sealing seams extending in the edge regions.
Die versiegelbare Lage der Folienbahn sollte durch eine Polyethylenschicht, die als Sperrschicht wirkende Lage der Folienbahn durch eine Polyamidschicht gebildet sein, wobei die Polyethylenschicht über einen Haftvermittler mit der Polyamidschicht verbunden sein sollte.The sealable layer of the film web should be formed by a polyethylene layer which acts as a barrier layer of the film web through a polyamide layer, wherein the polyethylene layer should be connected via a bonding agent with the polyamide layer.
Angebracht ist es auch, um die geöffnete Folienverpackung wiederum verschließen zu können, auf deren Außenseite im Bereich der Verschlussklappe oder auf dieser vorzugsweise im Anschluss an die Schicht des Heißsiegellackes eine doppelseitig wirkende Klebefolie anzuordnen.It is also appropriate to be able to close the opened film package in turn, to arrange a double-sided adhesive film on its outer side in the region of the closure flap or on this preferably subsequent to the layer of the heat sealing lacquer.
Die Folienbahn zur Herstellung einer Folienverpackung für sauerstoffempfindliche Lebensmittel sollte aus einer die Außenseite der Folienverpackung bildenden als Sperrschicht wirksamen Polyamidschicht und einer die Innenseite bildenden Polyethylenschicht, die miteinander mittels eines Haftvermittlers oder Klebers verbunden sind, und einer auf der Außenseite der Folienverpackung im Bereich der Verschlussklappe oder auf dieser aufgebrachten Schicht aus einem Heißsiegellack bestehen.The film web for producing a film packaging for oxygen-sensitive foodstuffs should consist of a polyamide layer which forms the outside of the film packaging and acts as a barrier layer and which forms the inside Polyethylene layer, which are connected to each other by means of a primer or adhesive, and on the outside of the film packaging in the region of the closure flap or applied thereto layer of a heat sealing lacquer.
Wird eine Folienverpackung gemäß der Erfindung ausgebildet, so ist nicht nur eine kostengünstige Herstellung bei geringem Fertigungs- und Materialaufwand gegeben, sondern es ist auch gewährleistet, dass die Folienverpackung eine hohe Betriebssicherheit aufweist. Die Folienbahn, aus der die Folienverpackung gefertigt wird, besteht nämlich lediglich aus zwei über einen Haftvermittler verbundenen Lagen, von denen eine Lage, die die Innenseite der Folienverpackung bildet, mit sich versiegelbar ist, die andere Lage bildet dagegen eine Barriereschicht gegen Sauerstoff. Die vorschlagsgemäße Verpackung ist demnach, ohne dass es eines zusätzlichen Aufwandes bedarf, insbesondere zur Einlagerung von sauerstoffempfindlichen Lebensmitteln vielseitig verwendbar.If a film package according to the invention is formed, then not only a cost-effective production with low manufacturing and material costs is given, but it is also ensured that the film packaging has a high reliability. The film web from which the film packaging is made, namely, consists of only two layers connected via a bonding agent, of which a layer which forms the inside of the film packaging, with it is sealable, the other layer, however, forms a barrier layer against oxygen. The proposed packaging is accordingly, without the need for additional effort, especially versatile for the storage of oxygen-sensitive foods.
Die Folienbahn, aus der die Verpackung in einer besonders einfachen Weise zu fertigen ist, ist in nur einem Arbeitsgang herzustellen, Störungen sind dabei nahezu ausgeschlossen. Dennoch ist mit Hilfe der im Bereich der Verpackungsöffnung vorgesehenen Schicht aus einem Heißsiegellack auch eine Versiegelung der Verschlussklappe, obwohl diese auf der als Sperrschicht wirkenden Außenseite der Folienbahn aufliegt, zu bewerkstelligen.The film web, from which the packaging is to be produced in a particularly simple manner, can be produced in only one operation, and disturbances are virtually eliminated. Nevertheless, with the aid of the layer of a heat sealing lacquer provided in the region of the packaging opening, sealing of the closing flap, although it rests on the outer side of the foil web acting as a barrier layer, is also to be accomplished.
