Description

Die Erfindung bezieht sich auf ein Verfahren zum Herstellen einer Verpackung gemäß dem Oberbegriff des Anspruchs 1, sowie auf eine zum Durchführen dieses Verfahrens geeignete Tiefziehverpackungsmaschine und auf eine durch das Verfahren oder mit der Tiefziehverpackungsmaschine herstellbare Verpackung.The invention relates to a method for producing a packaging according to the preamble of claim 1, as well as to a thermoforming packaging machine suitable for carrying out this method and to a packaging producible by the method or by the thermoforming packaging machine.

Das Herstellen von Verpackungen mittels Tiefziehverpackungsmaschinen ist weit verbreitet. Eine solche Tiefziehverpackungsmaschine, bei der Verpackungsmulden in eine meist aus Kunststoff bestehende Verpackungsfolie tiefgezogen und mit einem Produkt befüllt werden, ist in der DE 10 2007 013 698 A1 beschrieben.The production of packaging by thermoforming packaging machines is widespread. Such a thermoforming packaging machine, in which packaging trays are deep-drawn into a packaging film that is usually made of plastic and filled with a product, is in the DE 10 2007 013 698 A1 described.

Die DE 10 2007 013 698 A1 offenbart bereits, dass die Eigenschaften der Verpackung, insbesondere die Gasdurchlässigkeit des Verpackungsmaterials, einen erheblichen Einfluss auf die Haltbarkeit von in der Verpackung enthaltener, verderblicher Ware haben kann. Bei dieser Ware kann es sich insbesondere um Lebensmittel handeln.The DE 10 2007 013 698 A1 already discloses that the properties of the packaging, in particular the gas permeability of the packaging material, can have a considerable influence on the durability of perishable goods contained in the packaging. This product may be food in particular.

Verfahren zur Produktion von Verpackungen mit Gasbarriereschichten sind in der WO 02/074628 A1 , der WO 2008/092692 A1 sowie in der EP 2 067 717 A1 offenbart. Dabei sieht lediglich die erstere eine Beschichtung der Verpackungsmulden nach deren Ausformung vor. Bei den beiden anderen Dokumenten ist die Gasbarriereschicht bereits im Rohmaterial, aus dem die Verpackung hergestellt wird, vorgesehen.Processes for the production of packages with gas barrier layers are in the WO 02/074628 A1 , of the WO 2008/092692 A1 as well as in the EP 2 067 717 A1 disclosed. In this case, only the former provides for a coating of the packaging trays after they have been formed. For the other two documents, the gas barrier layer is already provided in the raw material from which the packaging is made.

Die EP 0 872 164 B1 und die WO 2008/0466553 A1 offenbaren Geräte zur Erzeugung von Mikrowellenplasmen. Diese beiden Dokumente deuten an, dass Werkstücke durch eine Plasmabehandlung beschichtet werden können, bei der sie dem durch die Geräte erzeugten Mikrowellenplasma ausgesetzt werden. Allerdings findet sich in den beiden Dokumenten keinerlei Bezug zu Verpackungen oder Verpackungsverfahren.The EP 0 872 164 B1 and the WO 2008/0466553 A1 disclose devices for generating microwave plasmas. These two documents suggest that workpieces may be coated by a plasma treatment, exposing them to the microwave plasma generated by the devices. However, the two documents have no relation to packaging or packaging processes.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zum Herstellen einer Verpackung und eine Tiefziehverpackungsmaschine dahingehend zu verbessern, dass mit konstruktiv möglichst einfachen Mitteln eine längere Haltbarkeit der verpackten Produkte erzielt wird.The object of the present invention is to improve a method for producing a packaging and a thermoforming packaging machine in such a way that a longer shelf life of the packaged products is achieved with structurally simple means as possible.

Diese Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1 sowie durch eine Tiefziehverpackungsmaschine mit den Merkmalen des Anspruchs 7. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a method having the features of claim 1 and by a thermoforming packaging machine with the features of claim 7. Advantageous developments of the invention are specified in the subclaims.

Das erfindungsgemäße Verfahren zeichnet sich dadurch aus, dass zumindest die Innen-und/oder die Außenseite der Verpackungsmulde nach dem Formen der Verpackungsmulde mit einer Barriereschicht beschichtet wird. Diese Gas-Barriereschicht beeinflusst die Gasdurchlässigkeit der Verpackungsfolie, insbesondere die Durchlässigkeit für Sauerstoff. Indem sie den Durchtritt von Sauerstoff durch die Verpackungsfolie vermindert, verlängert die Barriereschicht die Haltbarkeit eines verpackten Produkts. Das Aufbringen der Barriereschicht auf die Verpackungsmulde nach dem Formen der Verpackungsmulde hat gegenüber der theoretisch ebenfalls möglichen Verwendung einer bereits vor dem Formen der Verpackungsmulde beschichteten Verpackungsfolie den Vorteil, dass eine übermäßige Dehnung und Belastung der Barriereschicht beim Formen der Verpackungsmulde vermieden wird. Dies erlaubt es, bei der Erfindung auch sehr dünne Barriereschichten einzusetzen.The inventive method is characterized in that at least the inside and / or outside of the packaging tray is coated after forming the packaging tray with a barrier layer. This gas barrier layer affects the gas permeability of the packaging film, in particular the permeability to oxygen. By reducing the passage of oxygen through the packaging film, the barrier layer extends the shelf life of a packaged product. The application of the barrier layer on the packaging tray after forming the packaging tray has the advantage over the theoretically also possible use of a previously coated before forming the packaging tray packaging film that excessive stretching and stress of the barrier layer is avoided when forming the packaging tray. This makes it possible to use very thin barrier layers in the invention.

In einer Variante der Erfindung erfolgt die Beschichtung mit der Gas-Barriereschicht noch vor dem Befüllen der Verpackungsmulde mit einem Produkt. Auf diese Weise kann die Beschichtung ohne die möglicherweise störende Anwesenheit des Produkts durchgeführt werden.In one variant of the invention, the coating with the gas barrier layer takes place before filling the packaging trough with a product. In this way, the coating can be carried out without the possibly disturbing presence of the product.

Zusätzlich oder alternativ kann das Beschichten der Außenseite der Verpackung, d.h. der Verpackungsmulde und/oder einer die Verpackungsmulde verschließenden Oberfolie, nach der Herstellung der gesamten Verpackung erfolgen, d.h. nach dem Verschließen der Verpackungsmulde mit der Oberfolie. Diese Variante hat den Vorteil, dass damit auch sehr dünne oder flexible Folien beschichtet werden können, insbesondere Skinfolien. Nach dem Anlegen der als Oberfolie verwendeten Skinfolie an das Produkt unter einem Vakuum kann sich die Skinfolie nicht mehr bewegen. Auf diese Weise wird ein Abplatzen der erst nachträglich aufgebrachten Gas-Barriereschicht vermieden.
Vorzugsweise hat die Barriereschicht eine Sauerstofflässigkeit von weniger als 10 ccm pro (m2 x 24 Stunden x Druckunterschied [bar]). Mit anderen Worten tritt in diesem Fall pro 1 bar Druckunterschied in 24 Stunden ein Volumen von weniger als 10 ccm durch jeden Quadratmeter der mit der Barriereschicht versehenen Verpackungsfolie auf. Diese sehr geringe Sauerstoffdurchtrittsrate gewährleistet eine sehr lange Haltbarkeit des Produkts in der Verpackung.Additionally or alternatively, the coating of the outside of the packaging, ie the packaging tray and / or a top film closing the packaging tray, can take place after the production of the entire package, ie after closing the packaging tray with the top film. This variant has the advantage that even very thin or flexible films can be coated, in particular skin films. After applying the skin film used as the top film to the product under a vacuum, the skin film can not move. In this way, a spalling of the subsequently applied gas-barrier layer is avoided.
Preferably, the barrier layer has an oxygen content of less than 10 cc per (m 2 x 24 hours x pressure difference [bar]). In other words, in this case, a volume of less than 10 cc per every square meter of the packaging film provided with the barrier layer occurs per 1 bar pressure difference in 24 hours. This very low oxygen penetration rate ensures a very long shelf life of the product in the packaging.

Als besonders günstig hat es sich erwiesen, wenn das Beschichten der Verpackungsmulde mit der Barriereschicht mittels einer Plasmabeschichtung erfolgt. Diese Art der Verpackung erlaubt es, äußerst gasundurchlässige Barriereschichten auch auf kompliziert geformte Verpackungen in durchgehend konstanter Stärke aufzubringen.It has proven to be particularly favorable if the coating of the packaging tray with the barrier layer by means of a plasma coating. This type of packaging allows highly gas-impermeable barrier layers to be applied even on complicated-shaped packaging in consistently constant thickness.

Das für die Plasmabeschichtung erforderliche Plasma kann beispielsweise in einer zum Herstellen der Verpackung verwendeten Verpackungsmaschine selbst erzeugt werden. Damit wird die Plasmabeschichtungsvorrichtung in die Verpackungsmaschine integriert, und die gesamte Verpackungsmaschine wird deutlich kompakter, als wenn eine zusätzliche Plasmabeschichtungsanlage vorgesehen wäre.The plasma required for the plasma coating can be produced, for example, in a packaging machine used to produce the packaging itself. Thus, the plasma coating apparatus is integrated into the packaging machine, and the entire packaging machine is much more compact than if an additional plasma coating system would be provided.

Das erfindungsgemäße Verfahren ist besonders geeignet zur Verwendung einer biologisch abbaubaren Verpackungsfolie. Sehr geringe Gasdurchtrittsraten ließen sich auch mit herkömmlichen Mehrschichtfolien erreichen, beispielsweise einer EVOH-Folie (Ethylen-VinylAlkohol-Folie). Diese hatten jedoch den Nachteil, dass sie vergleichsweise dick sein mussten, und dass die Gasbarriereschicht bei der EVOH-Folie feuchtigkeitsempfindlich war. Folglich konnte sich diese Barriereschicht wieder stärker gasdurchlässig werden, wenn beispielsweise feuchte Lebensmittel in der Verpackung enthalten waren. Damit reduzierte sich die Haltbarkeitsdauer.The inventive method is particularly suitable for use of a biodegradable packaging film. Very low gas penetration rates could also be achieved with conventional multilayer films, for example an EVOH film (ethylene-vinyl alcohol film). However, these had the disadvantage that they had to be comparatively thick, and that the gas barrier layer in the EVOH film was sensitive to moisture. Consequently, this barrier layer could become more gas-permeable again, for example, if moist food was included in the packaging. This reduced the shelf life.

Biologisch abbaubare Folien, beispielsweise Folien aus Biokunststoff wie z.B. PLA (Polylactid, Polymilchsäure) sind üblicherweise sehr gasdurchlässig. Das erfindungsgemäße Verfahren erlaubt es nun, eine sehr dünne Barriereschicht auf diese Folien aufzubringen, um ihre Gasdurchlässigkeit herabzusetzen, ohne den Vorteil der biologischen Abbaubarkeit dieser Folien nennenswert zu beeinträchtigen.Biodegradable films, for example bioplastic films such as e.g. PLA (polylactide, polylactic acid) are usually very permeable to gas. The method according to the invention now makes it possible to apply a very thin barrier layer to these films in order to reduce their gas permeability without appreciably impairing the advantage of the biodegradability of these films.

Die Barriereschicht selbst kann beispielsweise SiOx und/oder A10x aufweisen oder daraus bestehen.The barrier layer itself may comprise or consist of, for example, SiOx and / or A10x.

Die Erfindung bezieht sich auch auf eine Tiefziehverpackungsmaschine mit einer Formstation zum Formen von Verpackungsmulden in eine Verpackungsfolie, sowie mit einer Füllstation. Zwischen der Formstation und der Füllstation und/oder stromabwärts einer Station zum Verschließen der Verpackungsmulden mit einer Oberfolie ist erfindungsgemäß eine Beschichtungsstation vorgesehen und dazu ausgebildet, zumindest die Innen- und/oder die Außenseite der Verpackungsmulde mit einer Barriereschicht zu beschichten. Dadurch werden die vorstehend beschriebenen Vorteile erzielt.The invention also relates to a thermoforming packaging machine with a forming station for forming packaging trays in a packaging film, as well as with a filling station. Between the forming station and the filling station and / or downstream of a station for closing the packaging troughs with a top film, a coating station is provided according to the invention and designed to coat at least the inside and / or the outside of the packaging trough with a barrier layer. Thereby, the advantages described above are achieved.

Die Beschichtungsstation kann beispielsweise zum Aufbringen einer Barriereschicht mit einer Dicke von weniger als einem Mikrometer eingerichtet sein. Selbst mit einer solchen, sehr dünnen Schicht kann die Gasdurchlässigkeit des Verpackungsmaterials stark, eingeschränkt werden.For example, the coating station may be configured to apply a barrier layer having a thickness of less than one micron. Even with such a very thin layer, the gas permeability of the packaging material can be severely restricted.

Ferner bezieht sich die Erfindung auf eine Verpackung mit einer aus einer tiefziehbaren Verpackungsfolie geformten Verpackungsmulde, bei der die Innen- und/oder die Außenseite der Verpackungsmulde mit einer Barriereschicht beschichtet ist.Furthermore, the invention relates to a packaging with a formed from a thermoformable packaging film packaging tray in which the inside and / or outside of the packaging tray is coated with a barrier layer.

Bereits erläutert worden ist, dass die Verpackungsfolie vorzugsweise biologisch abbaubar ist.It has already been explained that the packaging film is preferably biodegradable.

Um eine besonders lange Haltbarkeit zu gewährleisten, ist es vorteilhaft, wenn die mit der Barriereschicht versehene Verpackungsfolie eine Sauerstoffdurchlässigkeit von weniger als 10 ccm pro (m2 x 24 Stunden x Druckunterschied [bar]) aufweist.To ensure a particularly long shelf life, it is advantageous if the packaging film provided with the barrier layer has an oxygen permeability of less than 10 cc per (m 2 x 24 hours x pressure difference [bar]).

In einer vorteilhaften Variante der Erfindung ist die Barriereschicht feuchtigkeitsunempfindlich. Damit ist sie besonders geeignet zur Verwendung in einer Verpackung, mit der feuchte Lebensmittel verpackt werden.In an advantageous variant of the invention, the barrier layer is insensitive to moisture. Thus, it is particularly suitable for use in a package, are packed with the moist food.

Die Barriereschicht kann Siliziumoxid (SiOx) und/oder Aluminiumoxid (A10x) aufweisen.The barrier layer may comprise silicon oxide (SiOx) and / or aluminum oxide (A10x).

Im Folgenden wird ein vorteilhaftes Ausführungsbeispiel der Erfindung anhand einer Zeichnung näher dargestellt. Im Einzelnen zeigen:

Figur 1 zeigt in schematischer Seitenansicht eine erfindungsgemäße Verpackungsmaschine 1 in Form einer Tiefziehverpackungsmaschine. Die Verpackungsmaschine 1 verfügt über eine Formstation 2. In der Formstation 2 werden in eine von einer Folienrolle 3 abgezogene Verpackungsfolie 4 durch Tiefziehen Verpackungsmulden 5 geformt. FIG. 1 shows a schematic side view of a packaging machine 1 according to the invention in the form of a thermoforming packaging machine. The packaging machine 1 has a forming station 2. In the forming station 2 packaging trays 5 are formed by deep drawing in a withdrawn from a film roll 3 packaging film.

An einer Füllstation oder Einlegestation 6 wird ein Produkt 7 in die Verpackungsmulden 5 eingeführt. Bei diesem Produkt 7 kann es sich um ein Lebensmittel handeln, vorzugsweise um ein Lebensmittel 7 mit einer gewissen Feuchtigkeit.At a filling station or loading station 6, a product 7 is introduced into the packaging troughs 5. This product 7 may be a food, preferably a food 7 with a certain humidity.

Eine Siegelstation 8 der Verpackungsmaschine 1 dient zum Verschließen der Verpackungsmulden 5 mit einer Oberfolie 9. Die Oberfolie 9, bei der es sich wie bei der Verpackungsfolie 4 um eine siegelfähige Kunststofffolie handeln kann, wird von einer weiteren Folienrolle 10 abgezogen. Über eine Rollenführung 11 gelangt die Oberfolie 9 in die Siegelstation 8.A sealing station 8 of the packaging machine 1 is used to close the packaging troughs 5 with a top film 9. The top film 9, which may be a sealable plastic film as in the packaging film 4, is pulled off from another film roll 10. Via a roller guide 11, the upper film 9 enters the sealing station. 8

In der Siegelstation 8 kann eine hermetisch geschlossene Siegelkammer um die Verpackungsmulde 5 gebildet werden. Diese Siegelkammer wird evakuiert und gegebenenfalls mit einem Austauschgas begast, bevor ein Siegelwerkzeug die Oberfolie 9 an die Verpackungsmulde 5 ansiegelt, vorzugsweise an die Ränder der Verpackungsmulde 5. Der über die Verpackungsmulde 5 überstehende Teil der Oberfolie 9 kann noch in der Siegelstation 8 von der nun verschlossenen Verpackung 13 abgetrennt werden. Das Restfoliengitter 14 der Oberfolie 9 wird einem Restfolienaufwickler 15 zugeführt und dort gesammelt.In the sealing station 8, a hermetically sealed sealing chamber can be formed around the packaging trough 5. This sealing chamber is evacuated and possibly fumigated with a replacement gas before a sealing tool the upper film 9 is attached to the packaging tray 5, preferably to the edges of the packaging tray 5. The over the packaging tray 5 protruding part of the top film 9 can still in the sealing station 8 of the now sealed packaging 13 are separated. The remaining film grid 14 of the upper film 9 is fed to a Restfolienaufwickler 15 and collected there.

In Produktionsrichtung P stromabwärts der Siegelstation 8 sorgen eine Querschneideeinrichtung 16 und eine Längsschneideeinrichtung 17 für eine Vereinzelung der bisher noch im Verbund der Verpackungsfolie 4 befindlichen Verpackungen 13. Ein Förderband 18 dient zum Abtransport der fertigen und vereinzelten Verpackungen 13.In the direction of production P downstream of the sealing station 8, a cross-cutting device 16 and a longitudinal cutting device 17 ensure a separation of the packaging 13 still present in the composite of the packaging film 4. A conveyor belt 18 serves to remove the finished and separated packaging 13.

In Produktionsrichtung P ist zwischen der Formstation 2 und der Füllstation 6 eine Beschichtungsstation 19 vorgesehen. Im dargestellten Ausführungsbeispiel handelt es sich bei der Beschichtungsstation 19 um eine Plasmabeschichtungsstation 19. Die in die Verpackungsmaschine 1 integrierte Beschichtungsstation 19 verfügt über eine beispielsweise aus der WO 2008/046553 A1 bekannte Plasma-Erzeugungsvorrichtung 20, die in Figur 1 ebenfalls nur schematisch dargestellt ist. Das mittels der Plasma-Erzeugungsvorrichtung 20 erzeugte Plasma wird eingesetzt, um die Innen- und/oder die Außenseite der Verpackungsmulden 5 in der Beschichtungsstation 19 mittels einer Plasmabeschichtung oder durch eine plasmaunterstützte chemische Gasphasenabscheidung (PECVD) mit einer dünnen Barriereschicht zu beschichten.In the production direction P, a coating station 19 is provided between the forming station 2 and the filling station 6. In the illustrated embodiment, the coating station 19 is a plasma coating station 19. The coating station 19 integrated into the packaging machine 1 has one, for example, from the WO 2008/046553 A1 known plasma generating device 20, which in FIG. 1 also shown only schematically. The plasma generated by the plasma generating device 20 is used to seal the inside and / or outside of the packaging troughs 5 in the coating station 19 by means of a plasma coating or a plasma-assisted chemical vapor deposition (PECVD) with a thin barrier layer.

Im Ausführungsbeispiel des erfindungsgemäßen Verfahrens bzw. beim Betrieb der in Figur 1 gezeigten Verpackungsmaschine 1 wird diese Verpackungsmaschine 1 taktweise bzw. zyklisch betrieben. In jedem Arbeitstakt wird ein Abschnitt der Verpackungsfolie 4 von der Folienrolle 3 abgezogen. Beim Stillstand der Verpackungsfolie 4 schließt sich die Formstation 2, um eine Verpackungsmulde 5 oder ein Feld von nebeneinander liegenden Verpackungsmulden 5 in die Verpackungsfolie 4 tiefzuziehen.In the embodiment of the method according to the invention or in the operation of in FIG. 1 shown packaging machine 1, this packaging machine 1 is operated cyclically or cyclically. In each work cycle, a portion of the packaging film 4 is removed from the film roll 3. At standstill of the packaging film 4, the forming station 2 closes to deep draw a packaging tray 5 or a box of adjacent packaging trays 5 in the packaging film 4.

Beim Weitertransport gelangen die Verpackungsmulden 5 in die Beschichtungsstation 19, in der ihre Innen- und/oder ihre Außenseite mit einer dünnen Gasbarriereschicht versehen wird.Upon further transport, the packaging troughs 5 reach the coating station 19, in which their inner and / or outer side is provided with a thin gas barrier layer.

Nachdem die Verpackungsmulden 5 in der Füllstation 6 mit einem Produkt 7 befüllt wurden, gelangen sie in die Siegelstation 8. Dort wird ein Vakuum in den Verpackungsmulden 5 erzeugt und/oder ein Austauschgas(-gemisch) in die Verpackungsmulden 5 geführt, bevor die Verpackungsmulden 5 mit der Oberfolie 9 gasdicht versiegelt werden. Beim Weitertransport der nun verschlossenen Verpackungen 13 in Produktionsrichtung P werden die Verpackungen 13 mittels der Quer- und Längsschneideeinrichtungen 16, 17 vereinzelt.After the packaging troughs 5 were filled in the filling station 6 with a product 7, they get into the sealing station 8. There, a vacuum is generated in the packaging troughs 5 and / or a replacement gas (mixture) in the packaging troughs 5 before the packaging troughs. 5 sealed with the top film 9 gas-tight. During further transport of the now sealed packaging 13 in the production direction P, the packages 13 are separated by means of the transverse and longitudinal cutting devices 16, 17.

Figur 2 zeigt einen schematischen Vertikalschnitt durch ein Ausführungsbeispiel einer erfindungsgemäßen Verpackung 13, die mit der Verpackungsmaschine 1 hergestellt werden kann. Die Verpackung 13 weist eine Verpackungsmulde 5 auf, die durch Tiefziehen in die Verpackungsfolie 4 eingeformt ist. Bei der Verpackungsfolie 4 handelt es sich im dargestellten Ausführungsbeispiel um eine Verpackungsfolie aus einem biologisch abbaubaren Kunststoff, auch bezeichnet als Biokunststoff oder Bioplastic. Beispielsweise kann es sich dabei um PLA (Polyactid, Polymilchsäure) handeln. FIG. 2 shows a schematic vertical section through an embodiment of a package 13 according to the invention, which can be produced with the packaging machine 1. The package 13 has a packaging tray 5, which is formed by deep drawing in the packaging film 4. In the illustrated embodiment, the packaging film 4 is a packaging film made of a biodegradable plastic, also referred to as bioplastic or bioplastic. For example, it can be PLA (polyactide, polylactic acid).

Die Verpackungsmulde 5 verfügt über eine Innenseite 21 und eine Außenseite 22. Im dargestellten Ausführungsbeispiel ist nur die Innenseite 21 in der Plasma-Beschichtungsstation 19 mit einer Gasbarriereschicht 23 versehen worden. Die Gasbarriereschicht 23 hat eine Dicke von weniger als einem Mikrometer. Sie ist feuchtigkeitsunempfindlich, d.h. sie ändert ihre Eigenschaften unter dem Einfluss von Feuchtigkeit nicht. Die Barriereschicht 23 kann aus SiOx oder aus AIOx bestehen. Der mit der Barriereschicht 23 versehende Bereich der Verpackungsfolie 4 hat eine Gasdurchlässigkeit insbesondere für Sauerstoff von weniger als 10 ccm pro (m2 x 24 Stunden x Druckunterschied [bar]). Damit wird gewährleistet, dass nur eine verschwindend geringe Menge von Sauerstoff in die Verpackung 13 eintreten kann, so dass das in der Verpackung 13 enthaltene Produkt 7 eine lange Haltbarkeit erhält.The packaging tray 5 has an inner side 21 and an outer side 22. In the exemplary embodiment shown, only the inner side 21 in the plasma coating station 19 has been provided with a gas barrier layer 23. The gas barrier layer 23 has a thickness of less than one micron. It is insensitive to moisture, ie it does not change its properties under the influence of moisture. The barrier layer 23 can made of SiOx or AIOx. The region of the packaging film 4 provided with the barrier layer 23 has a gas permeability, in particular for oxygen, of less than 10 cc per (m 2 x 24 hours x pressure difference [bar]). This ensures that only a negligible amount of oxygen can enter the package 13, so that the product 7 contained in the package 13 is given a long shelf life.

Auf die Ränder 24 der Verpackungsmulde 5 ist eine Oberfolie 9 aufgesiegelt, die ebenfalls für einen gasdichten Verschluss der Verpackung 13 sorgt.On the edges 24 of the packaging tray 5, a top film 9 is sealed, which also provides a gas-tight closure of the package 13.

Ausgehend von dem dargestellten Ausführungsbeispiel können die erfindungsgemäße Verpackungsmaschine 1, das erfindungsgemäße Verfahren oder die erfindungsgemäße Verpackung 13 in vielfacher Hinsicht verändert werden. Insbesondere ist es denkbar, die Barriereschicht 23 nicht oder nicht nur auf der Innenseite 21 der Verpackungsmulde 5 aufzubringen, sondern zusätzlich oder stattdessen auf der Außenseite 23 der Verpackungsmulde 5. Durch ein Aufbringen der Barriereschicht 23 auf beiden Seiten 21, 22 der Verpackungsmulde 5 kann eine besonders gasdichte Verpackung 13 zur Verfügung gestellt werden.Starting from the illustrated embodiment, the packaging machine 1 according to the invention, the method according to the invention or the packaging 13 according to the invention can be modified in many ways. In particular, it is conceivable not to apply the barrier layer 23 or not only on the inside 21 of the packaging tray 5, but additionally or instead on the outside 23 of the packaging tray 5. By applying the barrier layer 23 on both sides 21, 22 of the packaging tray 5, a particularly gas-tight packaging 13 can be provided.

Bereits erwähnt wurde, dass zusätzlich oder alternativ zu der in Figur 1 gezeigten Beschichtungsstation auch eine Beschichtungsstation 19 stromabwärts von der Siegelstation 8 angeordnet sein kann, insbesondere also zwischen der Siegelstation 8 und der Trenneinrichtung 16. Diese Variante bietet sich insbesondere dann an, wenn als Oberfolie 9 eine sehr dünne Folie verwendet wird, beispielsweise einer Skinfolie, die erst nach dem Aufbringen auf die Verpackungsmulde 5 eine genügend hohe Formstabilität hat. In einer stromabwärts der Siegelstation 8 gelegenen Beschichtungsstation 19 kann die gesamte Außenseite der Verpackung 13 mit einer Gas-Barriereschicht 23 versehen werden, d.h. die Außenseite 22 der Verpackungsmulde 5 sowie die Außenseite der Oberfolie 9.It has already been mentioned that additionally or alternatively to the in FIG. 1 A coating station 19 can also be arranged downstream of the sealing station 8, in particular between the sealing station 8 and the separating device 16. This variant is particularly suitable when a very thin film is used as the upper film 9, for example a skin film which only after application to the packaging tray 5 has a sufficiently high dimensional stability. In a coating station 19 located downstream of the sealing station 8, the entire outside of the package 13 can be provided with a gas barrier layer 23, ie the outside 22 of the packaging tray 5 and the outside of the top film 9.

In einer weiteren Variante ist es denkbar, dass auch die Außen- und/oder die Innenseite der Oberfolie 9, d.h. die der Verpackungsmulde 5 ab- bzw. zugewandte Seite der Oberfolie 9, mit einer Gas-Barriereschicht 23 beschichtet wird. Zu diesem Zweck kann eine (weitere) Beschichtungsstation 19 im Bereich der Zuführung der Oberfolie 9 zur Siegelstation 8 vorgesehen sein.In a further variant, it is conceivable that the outer and / or inner side of the upper film 9, ie the side of the upper film 9 facing away from the packaging trough 5, is also coated with a gas barrier layer 23. For this purpose, a (further) coating station 19 may be provided in the region of the feed of the upper film 9 to the sealing station 8.

Des Weiteren ist es denkbar, als Gas-Barriereschicht 23 eine Aluminiumschicht vorzusehen, die durch Bedampfen auf die Verpackungsmulde 5 und/oder auf die Oberfolie 9 aufgebracht wird. Nachteilig an einer Aluminiumbeschichtung ist jedoch unter Umständen, dass die damit beschichteten Bereiche der Verpackung 13 nicht mehr durchsichtig sind. Eine Beschichtung beispielsweise mit Aluminiumoxid und/oder Siliziumoxid hat demgegenüber den Vorteil, dass ein Transparenzverlust von nur maximal 20 Prozent auftritt, so dass auch die mit der Barriereschicht 23 versehenen Bereiche der Verpackung 13 weiterhin durchsichtig bleiben.Furthermore, it is conceivable to provide as the gas barrier layer 23 an aluminum layer which is applied by vapor deposition to the packaging trough 5 and / or to the top film 9. However, a disadvantage of an aluminum coating may be that the areas of the packaging 13 coated therewith are no longer transparent. A coating, for example, with aluminum oxide and / or silicon oxide has the advantage that a loss of transparency of only a maximum of 20 percent occurs, so that even the areas provided with the barrier layer 23 of the package 13 remain transparent.
