Abstract
Description
Die vorliegende Erfindung betrifft einen Beutel zur Aufnahme von Lebensmitteln, insbesondere von aufzuwärmenden oder zu garenden Lebensmitteln und/oder von vorgebackener und/oder aufzubackender Backware, mit einem im Wesentlichen geschlossenen Bodenende und einem gegenüberliegenden Öffnungsende, umfassend eine Vorderwand und eine Rückwand, die im Bereich ihrer Seitenränder und Bodenränder zumindest abschnittsweise direkt oder über Seitenwände miteinander verbunden sind. Ferner betrifft die vorliegende Erfindung die Verwendung dieser Beutel als Aufbackbeutel oder Aufwärmbeutel für Backware bzw. Lebensmittel.The present invention relates to a bag for holding foodstuffs, in particular foods to be warmed or to be cooked and / or baked goods to be baked and / or baked, having a substantially closed bottom end and an opposite opening end, comprising a front wall and a rear wall which are in the area their side edges and bottom edges are at least partially connected directly or via side walls. Furthermore, the present invention relates to the use of these bags as baking bags or Aufwärmbeutel for baked goods or food.
Backwaren werden regelmäßig schon aus hygienischen Gründen in einer Verpackung an den Kunden übergeben. Dieses gilt ebenfalls für aufgewärmte bzw. aufgebackene Produkte. Zum Zwecke der leichteren Handhabung sowie der Minimierung von Transport-, Umpack- und Verarbeitungsschritten werden zu erwärmende bzw. aufzubackende Lebensmittelprodukte nicht selten bereits in dem eigentlichen Verkaufsgebinde angeliefert und am Ort des Verkaufs kurz vor dem eigentlichen Verzehr erwärmt bzw. aufgebacken. Für unmittelbar vor dem Verkauf fertig- bzw. aufzubackende Backware ist zudem zu beachten, dass diese in der Regel nach dem Vorbackvorgang, d.h. noch warm in die Verkaufsverpackung eingeführt und in dieser bei etwa -20° Celsius tiefgefroren gelagert wird. Erst kurz vor dem Fertigbacken lässt man die vorgebackene Backware in der Verkaufsverpackung auftauen und setzt sie Backtemperaturen von 180°C bis 200°C aus. Die zu erwärmenden bzw. aufzubackenden Lebensmittel geben beim Erwärmen bzw. Aufbacken regelmäßig Öle und Fettstoffe ab. Bei herkömmlichen Aufbackbeuteln führt dieses nicht selten dazu, dass diese Beutel für die weitere Handhabung nur noch eingeschränkt oder gar nicht mehr genutzt werden können, z.B. fetttriefend sind und zudem ein nicht mehr optimales Erscheinungsbild liefern. Auch geht mit der Verwendung herkömmlicher Aufbackbeutel kein geringer Reinigungsaufwand bei den verwendeten Gargeräten einher. Während der Phasen der Reinigung können Aufback- und Gargeräte nicht bestimmungsgemäß eingesetzt werden. Außerdem muss Personal für das Reinigen freigestellt werden. Hiermit können unnötige Umsatzeinbußen einhergehen.For hygienic reasons, baked goods are regularly handed over to the customer in packaging. This also applies to warmed or baked products. For the purpose of easier handling and the minimization of transport, Umpack- and processing steps to be warmed or aufzubackende food products are often delivered already in the actual sales container and heated or baked at the point of sale shortly before the actual consumption. For bakery products that are ready to be baked or baked immediately before the sale, it should also be noted that these are usually introduced into the sales packaging after the pre-bake process, that is, they are still stored frozen at about -20 ° Celsius. Only shortly before the ready-to-bake, the prebaked baked goods are allowed to thaw in the sales packaging and they set baking temperatures from 180 ° C to 200 ° C. The food to be heated or aufzubackenden when heating or baking give off regularly oils and fatty substances. In conventional bakery bags this often leads to these bags for further handling only limited or no longer can be used, for example, are fat dripping and also provide a no longer optimal appearance. Also goes with the use of conventional baking bag no small amount of cleaning in the used Cooking appliances. During the phases of the cleaning, baking and cooking appliances can not be used as intended. In addition, personnel must be released for cleaning. This can be associated with unnecessary loss of revenue.
Demgemäß wäre es wünschenswert, auf solche Beutel zurückgreifen zu können, die auch bei erhöhten Temperaturen hinreichend gut und dauerhaft fettresistent sind, und zwar ohne lebensmittelrechtlich beanstandet werden zu können.Accordingly, it would be desirable to be able to rely on such bags, which are sufficiently good and permanently fat-resistant even at elevated temperatures, without being able to be complained about food law.
Demzufolge lag der vorliegenden Erfindung die Aufgabe zugrunde, Beutel, insbesondere Aufbackbeutel zur Verfügung zu stellen, die nicht mit den Nachteilen des Stands der Technik behaftet sind und mit denen sich das Lebensmittel insbesondere über einen längeren Zeitraum sowie über einen sehr großen Temperaturbereich lagern lässt, ohne seine Frische und Konsistenz einzubüßen und die auch noch nach dem Aufwärm- bzw. Aufbackvorgang ein ansprechendes optisches Erscheinungsbild liefern und als Verzehrbehältnis zu verwenden sind.Accordingly, the object of the present invention was to provide bags, in particular baking bags, which are not subject to the disadvantages of the prior art and with which the foodstuff can be stored, in particular over a relatively long period of time and over a very wide temperature range, without to lose its freshness and consistency and even after the warm-up or bake provide a pleasing visual appearance and are to be used as a consumption container.
Demgemäß wurde ein Beutel zur Aufnahme von Lebensmitteln, insbesondere von aufzuwärmenden oder zu garenden Lebensmitteln und/oder von vorgebackener und/oder aufzubackender Backware, mit einem im Wesentlichen geschlossenen Bodenende und einem gegenüberliegenden Öffnungsende gefunden, umfassend eine Vorderwand und eine Rückwand, die im Bereich ihrer Seitenränder und Bodenränder zumindest abschnittsweise direkt oder über Seitenwände miteinander verbunden sind, wobei die Vorderwand und/oder die Rückwand und gegebenenfalls auch mindestens eine Seitenwand, vorzugsweise sämtliche Seitenwände, Pergaminpapier und/oder ein ein- oder beidseitig fluorbeschichtetes Zellstoffpapier umfassen oder hieraus gebildet sind.Accordingly, a bag has been found for containing foodstuffs, in particular foodstuffs to be warmed or cooked and / or baked and / or baked baked goods, having a substantially closed bottom end and an opposite opening end, comprising a front wall and a rear wall which are in the area of their Side edges and bottom edges are at least partially connected to each other directly or via side walls, wherein the front wall and / or the rear wall and optionally also at least one side wall, preferably all side walls, glassine paper and / or a one- or two-sided fluorine-coated pulp paper include or are formed thereof.

The above features can both individually, be implemented in any combination or all of the glassine papers used in the invention.
Bei dem Pergaminpapier kann es sich um ein- oder mehrlagiges Pergaminpapier handeln. Dem Fachmann ist bekannt, zwei oder mehrere Lagen an Pergaminpapier aufeinander zu kaschieren. Demgemäß ist es bei den erfindungsgemäßen Beuteln selbstverständlich auch möglich, Pergaminpapiere zu verwenden, die aus mehreren Lagen an Pergaminpapier gebildet sind.The glassine paper may be single or multi-ply glassine paper. The person skilled in the art is aware of laminating two or more layers of glassine paper to one another. Accordingly, it is self-evident in the bags according to the invention also possible to use glassine papers, which are formed of several layers of glassine paper.
Das bei den erfindungsgemäßen Beuteln zum Einsatz kommende Pergaminpapier ist vorzugsweise präg- und/oder bedruckbar, insbesondere beidseitig präg- und/oder bedruckbar.The glassine paper used in the bags according to the invention is preferably embossable and / or printable, in particular embossable and / or printable on both sides.
Ferner kommen besonders bevorzugt solche Pergaminpapiere zum Einsatz, die nicht oberflächenbehandelt sind, insbesondere nicht mit Silicon-Substanzen oder mit fluorierten Substanzen behandelt worden sind.Furthermore, particularly preferably used are glassine papers which have not been surface-treated, in particular have not been treated with silicone substances or with fluorinated substances.
Papiere aus Zellstoff bzw. Papiere, die im Wesentlichen vollständig auf Zellstoff basieren, sind dem Fachmann ebenfalls bekannt. Dieses gilt auch für ein- oder beidseitig fluorbeschichtete Zellstoffpapiere. Wird beispielsweise kein besonderer Wert auf die Bedruckung oder die Druckqualität des Beutels gelegt, kann auf ein einseitig beschichtetes Zellstoffpapier zurückgegriffen werden.Pulp or paper papers which are substantially completely pulp based are also known to those skilled in the art. This also applies to one or both sides fluorinated cellulose papers. For example, if no particular value is placed on the printing or the print quality of the bag, it is possible to fall back on a single-sided coated cellulose paper.
Wird bei einem erfindungsgemäßen Beutel ein einseitig fluorbeschichtetes Zellstoffpapier eingesetzt, ist die fluorbeschichtete Seite dieses Papiers vorzugsweise der Beutelinnenseite zugewandt bzw. bildet die Beutelinnenseite. Hierbei handelt es sich regelmäßig um diejenige Seite, die dem aufzuwärmenden, aufzubackenden oder zu garenden Lebensmittelprodukt zugewandt ist bzw. mit diesem in Kontakt tritt.If, in a bag according to the invention, a pulp paper coated on one side with fluorine is used, the fluorine-coated side of this paper preferably faces the inside of the bag or forms the inside of the bag. This is usually the side that faces the food product to be heated, baked or cooked, or that comes into contact with it.
Das Flächengewicht besonders geeigneter fluorbeschichteter Zellstoffpapiere liegt im Bereich von 20 bis 150 g/m2, vorzugsweise im Bereich von 25 bis 140 g/m2 und besonders bevorzugt im Bereich von 30 bis 110 g/m2, beispielsweise im Bereich von 32 bis 100 g/m2, bestimmt gemäß ISO 536.The basis weight of particularly suitable fluorine-coated pulp papers is in the range from 20 to 150 g / m 2 , preferably in the range from 25 to 140 g / m 2 and particularly preferably in the range from 30 to 110 g / m 2 , for example in the range from 32 to 100 g / m 2 , determined according to ISO 536.
Grundsätzlich kommen als geeignete fluorbeschichtete Zellstoffpapiere alle Zellstoffpapiere in Betracht, die mit einer Fluor enthaltenden Verbindung behandelt worden sind. Hierbei kann es sich z.B. um partiell- oder perfluorierte Verbindungen, beispielsweise monomere wie polymere Verbindungen handeln. Besonders bevorzugt wird auf solche ein- oder beidseitig fluorbeschichteten Zellstoffpapiere zurückgegriffen, die im Wesentlichen frei von Fluortensiden ist, insbesondere im Wesentlichen frei von Fluortelomeralkohol (FTOH), Perfluoroctylsulfonaten (PFOS) und/oder Perfluoroctylsäure bzw. deren SalzenIn principle, suitable suitable fluorine-coated pulp papers are all cellulose papers which have been treated with a fluorine-containing compound.

Derartige Perforationslöcher sind im Durchschnitt von unmittelbar benachbarten Perforationslöchern in dem zum Einsatz kommenden Pergaminpapier oder in dem ein- oder beidseitig fluorbeschichtetem Zellstoffpapier in einer bevorzugten Ausgestaltung etwa 0,5 bis 2,0 cm beabstandet.The perforation holes preferably have an average diameter of 0.2 to 2.0 mm, particularly preferably 0.4 to 1.5 mm. Such perforation holes are on average spaced from immediately adjacent perforation holes in the glassine paper used or in the one or both sides fluoro-coated pulp paper in a preferred embodiment about 0.5 to 2.0 cm.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung sind auch solche Beutel mit umfasst, bei denen die Rückwand zumindest bereichsweise, insbesondere im Wesentlichen vollständig, aus Pergaminpapier gebildet ist oder besteht und bei denen die Vorderwand in mindestens einem ersten Bereich aus Pergaminpapier gebildet ist oder besteht und in mindestens einem zweiten Bereich aus einer transparenten oder transluzenten Kunststofffolie gebildet ist oder bei denen die Vorderwand aus der transparenten oder transluzenten zweiten Kunststofffolie gebildet ist, wobei das Pergaminpapier und die Kunststofffolie im Bereich überlappender Auflageflächen zumindest bereichsweise mit einem Kleber verbunden sind. Hierbei können gemäß einer Ausführungsform das Pergaminpapier und/oder die Kunststofffolie perforiert sind.According to a further aspect of the present invention, such bags are also included, in which the rear wall is or is at least partially, in particular substantially completely, made of glassine paper and in which the front wall is or is formed in at least a first region of glassine paper and in at least a second region is formed from a transparent or translucent plastic film or in which the front wall is formed from the transparent or translucent second plastic film, wherein the glassine paper and the plastic film are at least partially connected with an adhesive in the region of overlapping bearing surfaces. In this case, according to one embodiment, the glassine paper and / or the plastic film are perforated.
Ferner sind auch solche Beutel besonders geeignet, bei denen die Rückwand zumindest bereichsweise, insbesondere im Wesentlichen vollständig, aus ein- oder beidseitig fluorbeschichtetem Zellstoffpapier gebildet ist oder besteht und dass die Vorderwand in mindestens einem ersten Bereich aus ein- oder beidseitig fluorbeschichtetem Zellstoff papier gebildet ist oder besteht und in mindestens einem zweiten Bereich aus einer transparenten oder transluzenten Kunststofffolie gebildet ist oder bei denen die Vorderwand aus der transparenten oder transluzenten zweiten Kunststofffolie gebildet ist, wobei das ein- oder beidseitig fluorbeschichtete Zellstoffpapier und die Kunststofffolie im Bereich überlappender Auflageflächen zumindest bereichsweise mit einem Kleber verbunden sind.Furthermore, such bags are particularly suitable in which the rear wall is or at least partially, in particular substantially completely, formed of one or both sides fluoro-coated pulp paper or that the front wall in at least a first region of one or both sides fluoro-coated pulp paper is formed or exists and is formed in at least a second region of a transparent or translucent plastic film or in which the front wall of the transparent or translucent second plastic film is formed, wherein the on or Both sides fluoro-coated cellulose paper and the plastic film in the region of overlapping bearing surfaces are at least partially connected with an adhesive.
Für die Verklebung des Bodenendes des erfindungsgemäßen Beutels kann man z.B. auf Dispersionsklebstoffe, insbesondere auf Polyacrylatbasis, zurückgreifen. Diese sind vorzugsweise weichmacherfrei.For the bonding of the bottom end of the bag according to the invention, e.g. on dispersion adhesives, in particular polyacrylate based resort. These are preferably plasticizer-free.
Für die Verklebung von Papier und Kunststofffolie kann beispielsweise ein, vorzugsweise aliphatischer, Polyurethanschmelzklebstoff eingesetzt werden, z.B. ein einkomponentiger feuchtigkeitsvernetzender reaktiver Polyurethanschmelzklebstoff.For the bonding of paper and plastic film it is possible, for example, to use a, preferably aliphatic, polyurethane hotmelt adhesive, e.g. a one-component moisture-curing reactive polyurethane hot melt adhesive.
Die Kunststofffolie stellt zweckmäßiger Weise eine Polyesterfolie, insbesondere eine PET-Folie, oder eine Polypropylenfolie dar, vorzugsweise als ein- oder mehrlagige Folie in mono- oder biaxial orientierter Form. Besonders bevorzugt greift man auf Kunststofffolien, insbesondere PET-Folien mit keinem oder nur geringem Schrumpf zurück.The plastic film expediently represents a polyester film, in particular a PET film, or a polypropylene film, preferably as a single-layer or multi-layer film in mono- or biaxially oriented form. It is particularly preferable to resort to plastic films, in particular PET films, with little or no shrinkage.
Die erfindungsgemäßen Beutel eignen sich als Aufbackbeutel zum Aufbacken vorgebackener und/oder aufzubackender Backware bzw. als Aufwärm- oder Garbeutel für aufzuwärmende oder zu garende Lebensmittel wie Pizzen, Crêpes, Pfannkuchen, Burger und Reibekuchen.The pouches according to the invention are suitable as baking pouches for baking pre-baked and / or baked baked goods or as warming or cooking pouches for foods to be heated or cooked, such as pizzas, crepes, pancakes, burgers and potato pancakes.
Der vorliegenden Erfindung lag die überraschende Erkenntnis zugrunde, dass sich eine für Lebensmittel geeignete fett- und temperaturbeständige Verpackung erhalten lässt, die zudem allen lebensmittelrechtlichen Vorgaben genügt, wenn man diese im Wesentlichen ausschließlich aus Pergaminpapier und/oder aus einem ein- oder beidseitig fluorbeschichtetem Zellstoffpapier fertigt. Diese Papiere sind farbstabil, auch nach Unterwerfung unter einen Aufwärm- oder Garvorgang. Insbesondere verfügen diese Papiere bzw. die mit Hilfe dieser Papiere erhaltenen Beutel nach einem solchen Aufback-, Aufwärm- bzw. Garvorgang noch stets über eine hinreichende mechanische Stabilität bzw. Berstfestigkeit.The present invention was based on the surprising finding that it is possible to obtain a grease and temperature-resistant packaging suitable for foodstuffs, which also satisfies all foodstuffs requirements, if these are produced essentially exclusively from glassine paper and / or from a single- or double-sided fluorinated paper pulp paper , These papers are color stable, even after submission to a warm-up or cooking process. In particular, these papers, or the pouches obtained with the aid of these papers, after such baking, reheating or cooking process still always on a sufficient mechanical stability or bursting strength.
Die in der vorstehenden Beschreibung sowie in den Ansprüchen offenbarten Merkmale der Erfindung können sowohl einzeln als auch in jeder beliebigen Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausführungsformen wesentlich sein.The features of the invention disclosed in the foregoing description and in the claims may be essential both individually and in any combination for the realization of the invention in its various embodiments.
