Abstract

The material for bag type packaging for goods packed under vacuum comprises a compound foil (1) which provided with an additional layer (2) of a material with high heat resistance, medium stiffness and good printability.

Description

Die Erfindung richtet sich auf einen Beutelpackstoff umfassend eine Ver­ bundfolie für vakuumverpackte Güter, wie Kaffee oder dergleichen.The invention is directed to a bag packaging material comprising a ver bundle film for vacuum-packed goods, such as coffee or the like.

Herkömmlicherweise werden z. B. zum Verpacken von Kaffee Beutelpack­ stoffe bestehend auf einer Verbundfolie aus Polyester, Aluminium und Polyethylen eingesetzt. Diese bekannten Verbundfolien weisen den Nach­ teil auf, daß sich beim Evakuieren des Beutelinneren die Folie an das ver­ packte Produkt, also z. B. die Kaffeebohnen, anlegt und sich deshalb das verpackte Produkt abzeichnet. Im Falle einer Kaffeeverpackung entsteht so ein welliges äußeres Erscheinungsbild, welches nicht besonders ansehnlich ist und auch eine Beschriftung oder ein Dekor nicht gut lesbar macht und zur Wirkung bringt.Conventionally, e.g. B. for packing coffee bag pack fabrics consisting of a composite film made of polyester, aluminum and Polyethylene used. These known composite films have the after part on that when evacuating the inside of the bag the film to the ver packed product, e.g. B. creates the coffee beans and therefore that packaged product signed. In the case of coffee packaging, this is the result a wavy outer appearance, which is not particularly handsome is and also does not make labeling or decor easy to read and brings effect.

Um dieses Problem zu vermeiden, ist es bekannt, im Anschluß an die Eva­ kuierung um die Beutelpackung eine zusätzliche Papierhülle anzubringen. Dies erfordert einen gesonderten Arbeitsgang und verbirgt die Verbundfo­ lie, die als solche an sich, abgesehen von der Problematik der Wellung, optisch sehr ansprechend gestaltet werden kann.To avoid this problem, it is known to follow Eva Kuung to attach an additional paper sleeve to the bag pack. This requires a separate operation and hides the Verbundfo lie, as such, apart from the problem of the curl, optically very appealing.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Beu­ telpackstoff zu schaffen, der bei kostengünstiger Abpackung ein besonders ansprechendes äußeres Erscheinungsbild ermöglicht.Proceeding from this, the object of the invention is to create a Beu To create telpack material that is a special with inexpensive packaging appealing external appearance enables.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine weitere Materialbahn auf die Verbundfolie nur partiell aufkaschiert ist, wobei der jeweilige Zwischenraum zwischen dem nicht aufkaschierten Teil der weite­ ren Materialbahn und der Verbundfolie jeweils wenigstens einen Luft­ durchlaß nach außen hin aufweist. Mit Vorteil sind die Durchlässe als Durchbrechungen der Kaschierung realisiert.This object is achieved in that another Material web is only partially laminated onto the composite film, the respective space between the non-laminated part of the width  Ren material web and the composite film each have at least one air has passage to the outside. The passages are advantageous as Breakthroughs in the lamination realized.

Beim Evakuieren des Packungsinneren legt sich die Verbundfolie in her­ kömmlicher Weise an den Packungsinhalt an. Gleichzeitig werden die Durchlässe, die ohnehin aufgrund der fehlenden Kaschierung schon einen Luftdurchlaß ermöglichen, durch das Ausbeulen der Verbundfolie nach innen noch weiter geöffnet, so daß Luft in den Bereich unter der zusätzli­ chen Materialbahn, also in den nicht kaschierten Bereich, einfließen kann, so daß diese sich anders als die Verbundfolie nicht an das Verpackungsgut anlegt und dementsprechend eine gleichmäßige glatte Oberfläche gewähr­ leistet ist. Gleichzeitig haben diese Durchlaßöffnungen den Vorteil, daß ein so ausgestalteter Beutelpackstoff gerollt oder gestapelt werden kann, ohne daß dies durch etwaige Luftpolster behindert wird.When the interior of the package is evacuated, the composite film lies down conventionally to the contents of the pack. At the same time, the Passages, which anyway because of the lack of lamination Allow air passage by bulging the composite film after opened further inside so that air in the area under the additional chen material web, i.e. in the non-laminated area, so that, unlike the composite film, it does not adhere to the packaged goods creates and accordingly guarantee a uniform smooth surface is accomplished. At the same time, these passage openings have the advantage that a thus designed bag packaging material can be rolled or stacked without that this is hindered by any air cushions.

Vorzugsweise ist vorgesehen, daß eine Kaschierung in den Bereichen er­ folgt, die später zu Siegelnähten der Beutelpackung werden.It is preferably provided that a lamination in the areas he follows, which later become the sealed seams of the pouch.

Günstigerweise kann die zusätzliche Materialbahn inline beim Arbeitsgang Drucken aufkaschiert werden.Conveniently, the additional web of material can be inline during the operation Printing can be laminated.

Die zusätzliche Materialbahn weist günstigerweise eine hohe Hitzebestän­ digkeit und eine mittlere Steifigkeit auf und ist bedruckbar.The additional material web advantageously has a high heat resistance and a medium stiffness and is printable.

Durch die erfindungsgemäße Ausgestaltung entfällt eine aufwendige Um­ verpackung für derartige Vakuumpackungen, ein zweiter Arbeitsgang beim Verpacken ist entbehrlich und eine zusätzliche Lagerhaltung für die Um­ verpackung ist nicht mehr nötig.The configuration according to the invention eliminates the need for a complex order packaging for such vacuum packs, a second operation at  Packing is unnecessary and additional storage for the order packaging is no longer necessary.

Weiterhin wird eine Materialeinsparung erreicht, da für die erfindungsge­ mäße zusätzliche Materialbahn wesentlich dünnere Materialien im Ver­ gleich zu den herkömmlicherweise eingesetzten Umverpackungen verwen­ det werden können. Hierdurch reduzieren sich Abfallgebühren. Gleichzei­ tig eröffnen sich neue optische Gestaltungsmöglichkeiten. Es wird weiter­ hin eine Qualitätsverbesserung des Verpackungsprozesses erreicht, da ein Arbeitsgang mit den dort auftretenden potentiellen Mängeln entfällt.Furthermore, a material saving is achieved because for the fiction additional material web much thinner materials in the Ver use the same as the conventional packaging can be detected. This reduces waste fees. Gleichzei New optical design options are opening up. It will continue towards an improvement in the quality of the packaging process, since a Work step with the potential defects occurring there is omitted.

Für den Verbraucher ergibt sich der Vorteil, daß er nur eine Verpackung zu öffnen und zu entsorgen braucht.The advantage for the consumer is that he only has one package open and dispose of.

Nachfolgend wird die Erfindung anhand eines bevorzugten Ausführungs­ beispiels in Verbindung mit der Zeichnung näher beschrieben. Dabei zei­ gen:The invention is described below on the basis of a preferred embodiment example described in more detail in connection with the drawing. Here zei gene:

Fig. 1 einen schematischen Teilschnitt durch eine Beutelpackung mit Kaffeebohnen und Fig. 1 shows a schematic partial section through a bag pack with coffee beans and

Fig. 2 eine Draufsicht auf einen zugeschnittenen Beutelpackstoff ohne Packungsinhalt. Fig. 2 is a plan view of a cut bag packaging material without package content.

Ein erfindungsgemäßer Beutelpackstoff umfaßt in an sich bekannter Weise eine Verbundfolie 1 aus Polyethylen, Aluminium, Polyester (z. B. PET 12/A19/PE-LD80). A bag packaging material according to the invention comprises, in a manner known per se, a composite film 1 made of polyethylene, aluminum, polyester (e.g. PET 12 / A19 / PE-LD80).

Hierauf ist eine zusätzliche Materialbahn 2 partiell längs der Siegelzonen 3 unter Freilassung von Luftdurchlässen 4 aufkaschiert, so daß von dem auf­ kaschierten Bereich (Siegelzone) 3 ein Zwischenraum 5 umschlossen wird, der durch die Durchlässe 4 belüftbar ist.An additional material web 2 is then partially laminated along the sealing zones 3 , leaving air passages 4 free , so that an area 5 is enclosed by the laminated area (sealing zone) 3 and can be ventilated through the passages 4 .

Aus Fig. 1 ist erkennbar, daß beim Evakuieren des Innenraums 6 des Ver­ packungsbeutels 7 die Verbundfolie 1 sich an das Verpackungsgut, hier die Kaffeebohnen 8, anlegt, so daß sich dieses wellig nach außen abzeichnet. Aufgrund der Durchlässe 4 strömt demgegenüber Luft in den Zwischen­ raum 5 ein, so daß die äußere zusätzliche Materialbahn 2 die Bewegung der Verbundfolie 1 nicht mitmacht und eine unverändert weitgehend glatte Oberfläche nach außen hin erhalten bleibt.From Fig. 1 it can be seen that when evacuating the interior 6 of the packaging bag 7 Ver the composite film 1 is applied to the packaging, here the coffee beans 8 , so that this is wavy to the outside. Because of the passages 4 in contrast, air flows into the space 5, a, remains so that the outer additional material web 2 does not follow the movement of the composite sheet 1 to obtain an unchanged substantially smooth surface to the outside.
