Abstract

A packaging film is provided for foodstuffs, wherein the foodstuffs are preferably meat products. The a net is connected to one side of the film to increase resistance to tearing. The net is adhered to the film by a soluble edible adhesive. The film may be shaped into a container wherein the net lies predominantly on an outer side of the container. After filling the film with the foodstuff, the adhesive is dissolved, whereupon the net can be removed without destroying the film.

Description

Die Erfindung betrifft eine Verpackungsfoliefür Lebensmittel, insbesondere für Fleisch-, Wurst- oder Fischprodukte, wobei die Folie für den Verzehr geeignet ist und zur Erhöhung der Reißfestigkeit ein Netz an der Folie anliegt.The invention relates to a packaging film door Food, in particular for meat, sausage or Fish products, the film being suitable for consumption is and to increase the tensile strength of a network at the Foil is present.

Derartige Verpackungsfolien haben ein großes Einsatzgebiet und stellen einen hochwertigen Ersatz für natürliche Därme dar. Darüber hinaus sind sie aber auch zur Verpackung von Lebensmitteln geeignet, die man wegen ihrer Größe oder Form nicht in Naturdärme abfüllen kann. Allgemein sind sie für die Verpakkung von allen Arten eiweißhaltiger Lebensmittel besonders geeignet, wobei sie mit dem Eiweiß der Lebensmittel eine Verbindung eingehen können. Grundsätzlich kann es sich dabei um tierisches oder pflanzliches Eiweiß handeln.Such packaging films have a large Field of application and provide a high-quality replacement for natural intestines. Beyond that they are but also suitable for packaging food, because of their size or shape they are not in natural casings can fill. Generally, they are for the packaging of all kinds of protein foods especially suitable, taking with the protein of the food can make a connection. in principle it can be animal or vegetable Act protein.

Allerdings sind die beschriebenen Verpakkungsfolien nicht besonders reißfest; sie müssen daher, solange sie sich noch nicht mit dem Eiweiß der Lebensmittel verbunden haben, vorsichtig behandelt bzw. durch zusätzliche Maßnahmen verstärkt werden. Eine weit verbreitete Maßnahme zum Schutz der Folie besteht darin, daß man sie mit einem Netz umgibt, das in der Lage ist, das Gewicht der Lebensmittel und die daraus bei der Verarbeitung resultierenden Kräfte aufzufangen.However, the packaging films described are not particularly tear-resistant; they must, therefore, as long as they are not familiar with the protein of the food carefully handled or be reinforced by additional measures. A widespread measure to protect the film in that one surrounds them with a net, which in capable of reducing the weight of the food and the resulting to absorb forces resulting from processing.

So läßt man zur Automatisierung der Wurstherstellung Wurstmasse, Folie und Netz direkt aus einem Doppelfüllrohraustreten. Dabei ergeben sich jedoch Schwierigkeiten, insbesondere wenn die Folie zu einem Schlauch oder dergleichen geformt wird. So kann bis heute nicht zuverlässig gewährleistet werden, dass sich die Ränder der Folie gleichmäßig überlappen und ausreichend fest miteinander verbunden werden. Infolgedessen kommt es in diesem Bereich immer wieder zu Löchern oder Rissen, an denen die Fleisch- oder Wurstfüllung austritt. Die Füllung verbindet sich dann durch Koagulation mit dem Netz und beim anschließende Abziehen des Netzes wird die Füllung teilweise herausgerissen.So one lets to the automation of the Sausage making Sausage mass, foil and net directly from a double-fill tube. In doing so result However, difficulties, especially if the film to a hose or the like is formed. So can not be reliable today ensure that the edges of the film overlap evenly and be sufficiently firmly interconnected. As a result, it comes in this area again and again to holes or cracks, in which the meat or sausage filling exits. The filling then combines by coagulation with the net and then pulling off the net becomes the filling partially torn out.

Außerdem ist das beschriebene Verfahren, gleichgültig, ob die Eiweißfolie manuell oder automatisch mit einem Netz überzogen wird, sehr aufwendig.In addition, the method described, regardless of whether the protein film manually or automatically covered with a net, very expensive.

Außerdem ist durch die DE-A 1 217 238 ein künstlicher Wurstdarm bekannt geworden, der an der Außenseite einen Netzüberzug aufweist. Dieser Netzüberzug kann mit dem als Innenschlauch fungierenden Darm durch klebern verbunden sein. Um den Innenschlauch mit dem Netzüberzug zusammenzubringen, wird der Innenschlauch an seinem unteren Ende durch einen Stopfen abgedichtet und sodann über ein Blasrohr gestülpt und gerafft. Dieses Blasrohr ist an ein Gebläse angeschlossen, sodass der Innenschlauch mit innerem Überdruck beaufschlagt werden kann. Das obere Ende des Innenschlauches wird in einem großkalibrigen Rohr geführt, das an seiner Außenseite einen gerafften Netzschlauch trägt, der oben durch einen Stopfen verschlossen Ist. Innenschlauch und Netzschlauch sollen dann gleichzeitig nach oben abgezogen werden, wodurch der Innenschlauch aufgrund des inneren Überdruckes gegen den äußeren Netzschlauch gedrückt wird, sodass beide Schläuche miteinander verklebt werden können.In addition, an artificial sausage casing is known from DE-A 1 217 238 has become, which has a mesh cover on the outside. This Mesh cover can be glued to the intestine acting as an inner tube be connected. To the inner tube with the net cover bring together, the inner tube at its lower end by sealed a stopper and then slipped over a blowpipe and shirred. This blowpipe is connected to a blower, so that the inner tube can be acted upon with internal pressure. The upper end of the Inner tube is guided in a large-caliber tube, which at his Outside carries a shirred netting tube that up through a stopper is closed. Inner tube and mesh tube should then simultaneously be pulled off above, whereby the inner tube due to the inner Overpressure is pressed against the outer mesh tube, so both Hoses can be glued together.

Davon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Verpackungsfolie und ein Verfahren zum Verpacken von Lebensmitteln anzugeben, die qualitativ hochwertig sind, für die verpackten Lebensmittel einen guten Schutz sicherstellen, der Automatisierung zugänglich sind, Lebensmittel in unterschiedlichster Form zu verpacken gestatten und kostengünstig In der Herstellung bzw. Durchführung sind.Based on this, the invention has the object, a Packaging film and a method for packaging food which are of high quality, for the packaged food Ensure good protection, accessible to automation, food in a variety of forms to allow packaging and cost In the Production or implementation are.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale der Patentansprüche 1 und 11 gelöst.This object is achieved by the features of the claims 1 and 11 solved.

Dadurch dass Folie und Netz aneinander fixiert sind, ergeben sich wesentliche Vorteile bei der Verarbeitung. Zum einen kann die Folie nicht mehr unter dem Netz hin- und herrutschen und infolgedessen auch keine Falten mehr bilden, die andsrnorts zu Spannungen oder Rissen führen. Zum anderen lässt sich das Verbundmaterial aus Folie und Netz sehr viel einfacher und ohne Rissgefahr in die für die Lebensmittel gewünschten Außenformen bringen. Einige Formgebungen werden durch das Verbundmaterial sogar erstmals möglich, was neue verkaufsfördernde Präsentationsmöglichkeiten eröffnet. In diesem Zusammenhang sollten Netz und Folie natürlich miteinander verbunden sein, bevor die Folie verarbeitet wird, insbesondere bevor die Lebensmittel eingefüllt werden.The fact that film and net are fixed to each other, resulting in essential Advantages of processing. For one thing, the film can no longer under the Net back and slide and consequently no wrinkles form, the Otherwise, tensions or tears may result. On the other hand, that can be Composite of foil and net much easier and without risk of cracking in bring the desired outer shapes for the food. Some Forms are even possible by the composite material for the first time, what new promotional presentation options opened. In this context, network and Of course, foil be joined together before the Foil is processed, especially before the food be filled.

Neben der Verbundeigenschaft ist für die Erfindung die Lösbarkeit des Klebstoffes maßgeblich. Dadurch kann das im allgemeinen als unschön und störend empfundene Netz nach dem Fertigungs-, Koch oder Reifungsprozeß leicht wieder entfernt werden, weil dann die Folie hinreichend in Form gehalten wird, so daß ein Einreißen nicht mehr zu befürchten ist.In addition to the composite property is for the invention the solubility of the adhesive decisive. Thereby In general, this can be unpleasant and annoying felt net after the manufacturing, cook or Ripening process can be easily removed again because then the film is held sufficiently in shape, so that tearing is no longer to be feared.

Das Lösen von Netz und Folie könnte zwar bei genauer Dimensionierung der Klebwirkung einfach durch mechanisches Abreißen des Netzes erfolgen. Vorteilhaft ist jedoch ein Auflösen oder Zersetzen des Klebstoffes. Dies kann zum Beispiel durch längeren Kontakt mit Gasen oder entsprechenden Chemikalien erfolgen. Aus lebensmittelrechtlichen Gründen empfiehlt sich vor allem Wasser als Lösungsmittel. Sollten sich in Zukunft aber andere unbedenkliche Lösungsmittel finden, so können diese selbstverständlich ebensogut eingesetzt werden.The release of mesh and film could indeed at accurate dimensioning of the adhesive effect easy done by mechanical tearing of the network. However, it is advantageous to dissolve or decompose the Adhesive. This can be done, for example, by longer ones Contact with gases or similar chemicals respectively. For food law reasons recommends especially water as a solvent. Should In the future, however, other harmless solvents Of course, these can just as well be used.

Zur sachgerechten und qualitativ hochwertigen Verpackung sollte die Folie wasserdampf- und sauerstoffdurchlässig sein. Als Materialien kommen in erster Linie solche in Frage, die sich mit den Lebensmitteln, insbesondere mit deren Eiweiß, verbinden. Exemplarisch seien hier Eiweiß, Stärke, modifizierte Stärke, Zellulose, Polysaccharide oder Carrageen oder eine Mischung dieser Stoffe genannt. Besonders geeignet sind Polysaccharidfilme aus Pullulan, Carrageen, Genue-Gummi, Glyzerin, kristalliner Zellulose, Honigwachs, Alkohol, Zuckerester, Bohnenöl, Xantane-Gummi und Wasser. Geeignete Rezepturen sind beispielsweise Pullulan ca. 0,21 % Carrageen ca. 2,1 % Genue-Gummi ca. 2,1 % Glyzerin ca. 1,4 % Abicel RC-30 ca. 1,12 % Honigwachs ca. 0,07 % Alkohol ca. 4,0 % Wasser ca. 89 % (mittelmäßig wasserlöslich) oder Pullulan ca. 8,4 % Carrageen ca. 2,4 % Xantane-Gummi ca. 1,2 % Avicel ca. 1,96 % Zuckerester ca. 0,1 % Bohnenöl ca. 0,1 % Alkohol ca. 4,43 % Wasser ca. 81,4 % (schwer wasserlöslich) oder Pullulan ca. 0,9 % Avicel ca. 2,3 % Agar ca. 8,1 % Genue-Gummi ca. 0,45 % Xantane-Gummi ca. 0,45 % Zuckerester ca. 0,04 % Wasser ca. 88 % (sehr schwer wasserlöslich). Vorstehende Angaben beziehen sich auf Gewichtsprozent.For proper and high quality Packaging, the film should be permeable to water vapor and oxygen be. As materials come first Line those in question that deal with the foods, especially with their protein, connect. exemplary protein, starch, modified starch, Cellulose, polysaccharides or carrageenan or a mixture called these substances. Particularly suitable Polysaccharide films of pullulan, carrageenan, genue gum, Glycerin, crystalline cellulose, honey wax, alcohol, Sugar esters, bean oil, xantane gum and Water. Suitable formulations are, for example Pullulan approx. 0.21% carrageenan approx. 2.1% genue-gum about 2.1% glycerin about 1.4% Abicel RC-30 about 1.12% Honey wax approx. 0.07% alcohol approx. 4.0% water approx. 89% (moderately soluble in water) or pullulan about 8.4 % Carrageenan approx. 2.4% xantane gum approx. 1.2% Avicel approx. 1.96% sugar ester approx. 0.1% bean oil approx. 0.1% alcohol approx. 4.43% water approx. 81.4% (heavy water soluble) or pullulan approx. 0.9% Avicel approx. 2.3% Agar approx. 8.1% Genue Rubber approx. 0.45% Xantane Gum approx. 0.45% sugar ester approx. 0.04% water approx. 88% (very difficult to dissolve in water). Previous information refer to weight percent.

Vorzugsweise wird wasserunlösliche oder schwer wasserlösliche Folie verwendet, weil dann das bei der Kühlung entstehende Kondenswasser die Folie nicht auflösen kann.Preferably, water insoluble or difficult to use water-soluble film, because then the during cooling, condensation forms the film can not dissolve.

Mit dem Begriff "Netz" soll jegliche Art von Material gemeint sein, das im wesentlichen zwei Forderungen erfüllt: Erstens muß es reißfest sein, um die erwähnte Schutzeigenschaft für die Folie zu gewährleisten. Zweitens sollte es vorzugsweise luft- und wasserdampfdurchlässig sein, damit die Lebensmittel darin sachgerecht reifen und gelagert werden können.The term "net" is intended to mean any kind of material that meant essentially two demands fulfilled: First, it must be tear-resistant, to the mentioned To ensure protection of the film. Second, it should preferably be permeable to air and water vapor so that the foods in it are appropriate mature and can be stored.

Das Netz ist vorzugsweise ein grob- oder fein maschiges Gewebe, Gewirke oder Gestricke und besteht aus natürlichen oder Kunstfasern, wie zum Beispiel Zellwolle, Baumwolle, Polyethylen, Polypropylen und/oder Polyamid.The mesh is preferably coarse or fine mesh fabric, knitted or knitted fabric and consists made of natural or synthetic fibers, such as Creel, cotton, polyethylene, polypropylene and / or polyamide.

Als Klebstoff eignen sich besonders wasserlösliche Klebstoffe, etwa modifizierte Stärke und/oder Collagen. Außerdem sind auch Klebstoffe auf Gelatinebasis gut geeignet, etwa ein Kleber mit ca. 5 % bis ca. 30 % Gelatine und ca. 70% bis ca. 95 % Glyzerin oder ein Kleber mit ca. 50 % bis ca. 90 % Alkohol und ca. 10 % bis ca. 50 % Schellack.As the adhesive are particularly water-soluble Adhesives, such as modified starch and / or Collages. In addition, glues are also gelatin-based well suited, such as an adhesive with about 5% to about 30% gelatin and about 70% to about 95% glycerin or an adhesive with about 50% to about 90% alcohol and about 10 % to about 50% shellac.

Die Folie mitsamt ihrem Netz istvorteilhaftentlang zumindest einiger ihrer Ränder verbunden, so daß sie ein Behältnis, im einfachsten Fall einen Schlauch, formt. Durch den Verbund mit dem Netz kann die Folie erstmals entlang der Ränder nicht nur geklebt, sondern auch genäht oder geheftet werden. Dies ermöglicht eine wesentlich stabilere Verbindung, wodurch der Folie zahlreiche neue Anwendungsbereiche erschlossen werden.The film along with its net is advantageously long connected at least some of their edges, so that a container, in the simplest case a hose, shaped. By bonding with the net, the film can not only glued along the edges but first also sewn or stapled. This allows a much more stable connection, reducing the film Numerous new applications opened up become.

Schließlich kann die Folie aus ästhetischen Gründen oder zur markenmäßigen Kennzeichnung bedruckt sein. Die Schrift wird vorzugsweise auf der Innenseite angebracht, wozu die Folie transparent oder klar ist. Alternativ ist aber auch ein Einfärben der gesamten Folie denkbar.Finally, the film can be aesthetic Reasons or for brand marking printed be. The writing is preferably on the inside attached, to which the film transparent or clear is. Alternatively, however, is a coloring of the entire Foil conceivable.

Konkret hat man sich das erfindungsgemäße Verfahren zum Verpacken von Lebensmitteln mit der erfindungsgemäßen Folie folgendermaßen vorzustellen: Zuerst werden die Folie und das Netz mit Hilfe des lebensmittelrechtlich unbedenklichen Klebstoffes miteinanderverklebt. Dann ergeben sich prinzipiell zwei Möglichkeiten zur Weiterverarbeitung. Entweder wird das Verbundmaterial, insbesondere durch Nähen, Heften oder Kleben, zu einem Behältnis geformt, wobei Öffnungen zum Befüllen und gegebenenfalls zur Entlüftung freigelassen werden und das Netz zumindest überwiegend außen zu liegen kommt. Danach wird das Behältnis mit dem Lebensmittel gefüllt. Alternativ kann das Formen des Behältnisses auch direkt beim Einfüllen der Lebensmittel geschehen, indem diese von der Folie umhüllt werden.Concretely, one has the invention Method for packaging food with the inventive To present the film as follows: First, the foil and the net with the help of food law safe adhesive glued together. Then, in principle, there are two possibilities for further processing. Either that will Composite material, in particular by sewing, stapling or gluing, formed into a container, with openings for filling and possibly for venting be released and the network at least predominantly lies outside. Then the container filled with the food. Alternatively, the Forms of the container also directly when filling the Foods happen by wrapping them on the foil become.

Nach dem Befüllen und nach dem Reifen oder der Hitzebehandlung oder am Ende des Fertigungsprozesses hat sich die Folie mit den Lebensmitteln unlöslich verbunden und dann kann das Netz wieder entfernt werden. Dies geschieht durch einfaches Abziehen des Netzes nach vorausgegangenem Lösen des Klebstoffes. Das Lösen erfolgt zum Teil schon allein durch das Kondenswasser, das sich an den verpackten Lebensmitteln bildet. Darüber hinaus bietet sich Kochen, Abwaschen oder Duschen an, insbesondere dann, wenn dies zur Weiterverarbeitung der Lebensmittel sowieso angezeigt ist. Außerdem hat das Lösen des Klebstoffes mit Hilfe eines Lösungsmittels, insbesondere Wasser, den großen Vorteil, daß die Folie nach dem Entfernen des Netzes eine ästhetisch ansprechende Oberfläche ohne Klebstoffreste aufweist. After filling and after the tire or the heat treatment or at the end of the manufacturing process the film has become insoluble with the food connected and then the network can be removed again become. This is done by simply removing the Net after previous release of the adhesive. The release is done partly by the alone Condensation that adheres to the packaged food forms. In addition, offers cooking, washing dishes or showers, especially if this for further processing of the food anyway is displayed. In addition, the release of the adhesive has with the aid of a solvent, especially water, the big advantage that the film after removal of the net an aesthetically pleasing surface without adhesive residues.
