Definitions
- the present invention relates to a plastic film bag, in particular a tamper-proof plastic film bag, e.g. a duty-free plastic film bag.
- the invention further relates to a blank for a plastic film bag.
- the invention is based on the use of the plastic film bags according to the invention as transport and/or packaging containers, particularly in the duty-free sector.
- Plastic film bags are generally common, ready-to-use transport or packaging containers that are used for a variety of purposes. In order to keep material costs low, the thickness of the plastic films has been reduced from time to time. Common plastic carrier bags, such as those found in supermarkets, usually have a film thickness of around 60 ⁇ m. A further reduction in the thickness of the plastic films used is generally limited by the associated reduced tear resistance. Despite the low thickness of the films for plastic film bags, they are usually co-extruded film systems. The individual layers used here are often used to either ensure printability or to adjust the elastic or mechanical property profile to the respective intended use.
- plastic film bags that are to be used as transport or packaging containers in the duty-free area of airports, for example, in addition to the tear resistance, it is often of particular interest that manipulation of the contents can be ruled out after being filled with the duty-free item .
- plastic film bags for the duty-free sector are always produced in large numbers. If you want to avoid production interruptions, for example due to a product backlog at the level of intermediate products, special care is often required when conducting the process.
- the present invention was based on the object of making a plastic film bag available which does not suffer from the disadvantages of the prior art and which, in particular, provides fully functional plastic film bags, e.g. for the duty-free sector, in a material-saving manner and makes it accessible in a simple yet reliable way, especially in automated mass production.

- the particularly one-piece transition from the plastic film front wall to the plastic film rear wall is preferably designed as a fold or fold in the area of the upper edges of the plastic film bags according to the invention.
- the particularly one-piece transition from the plastic film front wall to the plastic film rear wall is also designed as a fold or fold in the area of their lower edges. This transition, which is designed as a fold or fold, then also forms the bottom of the bag or is part of it.
- the object on which the invention is based is preferably also achieved by plastic film bags according to the invention in which the plastic film front wall and the plastic film rear wall merge into one another in one piece at their respective first side edges in that section which lies below the first or second adhesive area, and in which the plastic film front wall and the Plastic film back wall in the area of the second side edges in the section welded together that lies below the first or second adhesive area.
- the plastic film front wall and the plastic film rear wall are welded together in the area of their first side edges in the section that lies below the first or second adhesive area, and that the Plastic film front wall and the plastic film rear wall are present welded together in the area of their second side edges in that section which lies below the first or second adhesive area.
- the transition from the plastic film front wall to the plastic film rear wall in the area of their first side edges, if they are not welded together is preferably designed as a fold or fold.
- plastic film bags in which the plastic film front wall and the plastic film rear wall are welded together in the area of their first side edges in the section that lies below the first or second adhesive area, and in which the plastic film front wall and the plastic film rear wall are also in the area of the second side edges of which are welded together in that section which lies below the first or second adhesive area.
- Embodiments are also particularly suitable in which the plastic film front wall and the plastic film rear wall merge into one another at their respective upper edges, in particular in one piece, and in which the plastic film front wall and the plastic film rear wall merge into one another at their respective lower edges, in particular in one piece.
- plastic film bags according to the invention are characterized in expedient embodiments in particular by the fact that the plastic film front wall and the plastic film rear wall do not merge into one another or are not connected to one another on their respective first side edges in that section which is in the area of the first or second adhesive area and extends up to Bag opening edge extends, and that the plastic film front wall and the plastic film rear wall do not merge into one another or are not connected to one another at their respective second side edges in that section which lies in the area of the first or second adhesive area and extends to the bag opening edge.
- the plastic film front wall preferably forms a fold-over closure tab with a width (C) in the area from the bag opening edge in the direction of the loot bottom, in which the first and second side edges of the plastic film front wall are not connected to the first and second side edges of the plastic film rear wall or do not merge into one another .
- the width (C) in this case represents the extent of the fold-over closure flap transversely to the extent between the first and second side edges of the plastic film front wall and plastic film rear wall from the bag opening edge in the direction of the bag bottom.
- Such plastic film bags according to the invention solve the problem on which the invention is based particularly reliably, in which the second adhesive area is in the area of the fold-over closure tab or in which the first adhesive area is on the inside of the plastic film rear wall in an area that can be brought into alignment with the fold-over closure flap.
- the width (A) of the first adhesive area or the width (B) of the second adhesive area is expediently regularly smaller or equal to the width (C) of the fold-over closure tab.
- the at least one connecting area of the plastic film bags according to the invention represents a weld seam, in particular a thermoplastic weld seam, which extends from the first side edges of the plastic film front wall and plastic film rear wall to the second side edges of the plastic film front wall and plastic film rear wall extends and which preferably runs essentially parallel, particularly preferably parallel, to the bag opening edge.
- a weld seam in particular a thermoplastic weld seam

- the present invention is accompanied by the surprising finding that plastic film bags are accessible in a very material-saving manner and nevertheless provide a reliable transport and/or packaging container that can even be used as a tamper-proof transport and/or packaging container, e.g. for the duty-free area. or can also be used as a fruit or vegetable carrier bag.
- Out of Figure 1 shows a first embodiment of a plastic film bag (1) according to the invention in a side sectional view with a plastic film front wall (2), containing an inner and an outer side (20, 22), with an upper and an opposite lower edge (8, 10) and a plastic film rear wall (18), containing an inner and an outer side (32, 34), with an upper and an opposite lower edge (28, 30). While the plastic film rear wall (18) is continuous, the bag opening (12) is in the plastic film front wall (2). Unlike conventional plastic carrier bags, the bag opening (12) is not located at the top end of the bag, but in the embodiment shown is located in the upper half of the plastic film front wall (2).
- the plastic film front wall (2) can be obtained, for example, by folding over a first film area (3) in the area that forms the upper edge (8) of the plastic film bag, and by folding over a second film area (5) in the area that forms the lower edge (36) of the plastic film bag.
- the bag opening (12) is therefore at a distance from the upper edge (8).

- the plastic film front wall (2) and the plastic film rear wall (18) are connected to one another or merge into one another up to or just below the first adhesive area (40). In this way, the upper section of the second area (5) of the plastic film front wall (2) remains unconnected to the plastic film rear wall (18) and forms a so-called fold-over closure tab (66).
- the second embodiment of a plastic film bag (1) according to the invention differs from the first embodiment Figure 1 that the adhesive area, in the present case called the second adhesive area (42), is not on the inside (32) of the plastic film rear wall (18), but on the inside (20) of the plastic film front wall (2).
- This second adhesive area (42) is attached below the bag opening edge (16), namely adjacent to this bag opening edge (16).
- the detention area (42) has a width (B).
- the width (B) is to be understood as an extension in the direction from the upper edge (8) to the lower edge (10).
- the embodiment of a plastic film bag according to the invention according to Figure 3 differs from the embodiment according to this alone Figure 1 that the bag bottom (36) is designed as a bottom with a bottom fold.
- FIG 4 shows the embodiment of a plastic film bag (1) according to the invention, as in Figure 1 reproduced, in a schematic side view.
- the plastic film front wall (2) and the plastic film rear wall (18) are welded together in the area of the first side edges (4, 24) in that section (44, 46) which lies below the first adhesive area (40).

- the upper section of the second area (5) of the plastic film front wall (2) thus remains unconnected to the plastic film rear wall (18) and forms the fold-over closure tab (66).
- the fourth embodiment of the plastic film bag according to the invention shown in a perspective view, essentially corresponds to that in the characters 1 and 4 illustrated embodiment.
- the only difference is that the plastic film front wall (2) and the plastic film rear wall (18) are not only welded together in the area of the first side edges (4, 6, 24, 26) in those sections (44, 46, 48, 50), which lie below the first adhesive area (40), but also in the area of the first film area (3) of the plastic film front wall (2).
- Figures 1 to 4 can be designed in such a way that the plastic film front wall (2) and the plastic film rear wall (18) are welded together not only in the area of the first side edges (4, 6, 24, 26) in those sections (44, 46, 48, 50) which are below the first adhesive area (40), but also in the area of the first film area (3) of the plastic film front wall (2).
- These embodiments are preferred. They provide an even higher level of stability and comfort.
- By folding the fold-over closure tab (66) outwards along the dashed line the opening of the plastic film bag can be enlarged again. This is very useful for the filling process.
- the fold-over closure tab (66) has a width (C), which in the embodiment shown essentially corresponds to the width (A) of the adhesive area (40).
- the bag opening (12) extends from the first side edge (4) of the plastic film front wall (2) to the second side edge (6) of the plastic film front wall (2).
- the connection area (38) also extends in the form of a weld seam from the first side edges (4, 24) of the plastic film front wall (2) and plastic film rear wall (18) to the second side edges (6, 26) of the plastic film front wall (2 ) and plastic film back wall (18).
- the adhesive area (40) extends from the first side edge (24) of the plastic film rear wall (18) to the second side edge (26) of the plastic film rear wall (18).
- the plastic film bag (1) according to Figure 6 differs from the embodiment according to this alone Figure 5 that in the area between the weld seam (38) and the upper edges (8,28) congruent handle holes (54,56) are provided in the plastic film front wall (2) and the plastic film rear wall (18). This type of attachment of handle holes allows even heavy goods to be transported very safely.
- FIG 7 shows a schematic representation of a blank according to the invention for a plastic film bag according to the invention according to the embodiment, as in Figure 6 reproduced, formed from a single-layer plastic film.

Description
Die vorliegende Erfindung betrifft einen Kunststofffolienbeutel, insbesondere einen manipulationssicheren Kunststofffolienbeutel, z.B. einen Duty-free-Kunststofffolienbeutel. Ferner betrifft die Erfindung einen Zuschnitt für einen Kunststofffolienbeutel. Schließlich stellt die Erfindung ab auf die Verwendung der erfindungsgemäßen Kunststofffolienbeutel als Transport- und/oder Verpackungsgebinde, insbesondere im Duty-free-Bereich.The present invention relates to a plastic film bag, in particular a tamper-proof plastic film bag, e.g. a duty-free plastic film bag. The invention further relates to a blank for a plastic film bag. Finally, the invention is based on the use of the plastic film bags according to the invention as transport and/or packaging containers, particularly in the duty-free sector.
Kunststofffolienbeutel stellen im Allgemeinen gängige gebrauchsfertige Transport- bzw. Verpackungsgebinde dar, die für vielfältige Zwecke eingesetzt werden. Um den Materialaufwand gering zu halten, ist zum Beispiel die Dicke der Kunststofffolien von Mal zu Mal reduziert worden. Übliche Kunststofftragetaschen, wie man sie aus Supermärkten kennt, verfügen in der Regel über eine Foliendicke im Bereich von etwa 60 µm. Einer noch weitergehenden Reduzierung der Dicke der verwendeten Kunststofffolien wird im Allgemeinen durch die damit einhergehende verminderte Reißfestigkeit eine Grenze gesetzt. Trotz der geringen Dicken der Folien für Kunststofffolienbeutel handelt es sich üblicherweise um coextrudierte Foliensysteme. Die hierbei zum Einsatz kommenden Einzellagen werden vielfach genutzt, um entweder die Bedruckbarkeit sicherzustellen oder um das elastische bzw. mechanische Eigenschaftsprofil auf den jeweiligen Verwendungszweck einzustellen.Plastic film bags are generally common, ready-to-use transport or packaging containers that are used for a variety of purposes. In order to keep material costs low, the thickness of the plastic films has been reduced from time to time. Common plastic carrier bags, such as those found in supermarkets, usually have a film thickness of around 60 µm. A further reduction in the thickness of the plastic films used is generally limited by the associated reduced tear resistance. Despite the low thickness of the films for plastic film bags, they are usually co-extruded film systems. The individual layers used here are often used to either ensure printability or to adjust the elastic or mechanical property profile to the respective intended use.
Für Kunststofffolienbeutel, die im Duty-free-Bereich von zum Beispiel Flughäfen als Transport- oder Verpackungsgebinde eingesetzt werden sollen, ist vielfach neben der Reißfestigkeit von besonderem Interesse, dass nach dem Befüllen mit dem Duty-Free-Artikel eine Manipulation des Inhalts ausgeschlossen werden kann. Wie viele andere Verkaufsgebinde werden auch Kunststofffolienbeutel für den Duty-free-Bereich stets in großer Zahl gefertigt. Möchte man Produktionsunterbrechungen vermeiden, beispielsweise bedingt durch einen Produktstau auf der Ebene von Zwischenprodukten, ist häufig eine besondere Obacht bei der Verfahrensführung erforderlich.For plastic film bags that are to be used as transport or packaging containers in the duty-free area of airports, for example, in addition to the tear resistance, it is often of particular interest that manipulation of the contents can be ruled out after being filled with the duty-free item . Like many other sales containers, plastic film bags for the duty-free sector are always produced in large numbers. If you want to avoid production interruptions, for example due to a product backlog at the level of intermediate products, special care is often required when conducting the process.

Die der Erfindung zugrunde liegende Aufgabe wird bevorzugt auch durch solche erfindungsgemäßen Kunststofffolienbeutel gelöst, bei denen die Kunststofffolienvorderwand und die Kunststofffolienrückwand an deren jeweiligen ersten Seitenrändern in demjenigen Abschnitt einstückig ineinander übergehen, der unterhalb des ersten oder zweiten Haftareals liegt, und bei denen die Kunststofffolienvorderwand und die Kunststofffolienrückwand im Bereich von deren zweiten Seitenrändern in demjenigen Abschnitt miteinander verschweißt vorliegen, der unterhalb des ersten oder zweiten Haftareals liegt. Alternativ kann, insbesondere unter herstellungstechnischen Aspekten, in einer bevorzugten Ausführungsform vorgesehen sein, dass die Kunststofffolienvorderwand und die Kunststofffolienrückwand im Bereich von deren ersten Seitenrändern in demjenigen Abschnitt miteinander verschweißt vorliegen, der unterhalb des ersten oder zweiten Haftareals liegt, und dass die Kunststofffolienvorderwand und die Kunststofffolienrückwand im Bereich von deren zweiten Seitenrändern in demjenigen Abschnitt miteinander verschweißt vorliegen, der unterhalb des ersten oder zweiten Haftareals liegt. Bei den vorangehend geschilderten Ausführungsformen ist der Übergang von Kunststofffolienvorderwand zu Kunststofffolienrückwand im Bereich von deren ersten Seitenrändern, sofern diese nicht miteinander verschweißt vorliegen, bevorzugt als Falte oder Falz ausgebildet.The object on which the invention is based is preferably also achieved by plastic film bags according to the invention in which the plastic film front wall and the plastic film rear wall merge into one another in one piece at their respective first side edges in that section which lies below the first or second adhesive area, and in which the plastic film front wall and the Plastic film back wall in the area of the second side edges in the section welded together that lies below the first or second adhesive area. Alternatively, in particular from a manufacturing perspective, it can be provided in a preferred embodiment that the plastic film front wall and the plastic film rear wall are welded together in the area of their first side edges in the section that lies below the first or second adhesive area, and that the Plastic film front wall and the plastic film rear wall are present welded together in the area of their second side edges in that section which lies below the first or second adhesive area. In the embodiments described above, the transition from the plastic film front wall to the plastic film rear wall in the area of their first side edges, if they are not welded together, is preferably designed as a fold or fold.
Besonders bevorzugt kommen auch solche Kunststofffolienbeutel zum Einsatz, bei denen die Kunststofffolienvorderwand und die Kunststofffolienrückwand im Bereich von deren ersten Seitenrändern in demjenigen Abschnitt miteinander verschweißt vorliegen, der unterhalb des ersten oder zweiten Haftareals liegt, und bei denen ferner die Kunststofffolienvorderwand und die Kunststofffolienrückwand im Bereich von deren zweiten Seitenrändern in demjenigen Abschnitt miteinander verschweißt vorliegen, der unterhalb des ersten oder zweiten Haftareals liegt. Hierbei sind auch solche Ausführungsformen besonders geeignet, bei denen zusätzlich die Kunststofffolienvorderwand und die Kunststofffolienrückwand an deren jeweiligen oberen Rändern, insbesondere einstückig, ineinander übergehen und bei denen die Kunststofffolienvorderwand und die Kunststofffolienrückwand an deren jeweiligen unteren Rändern, insbesondere einstückig, ineinander übergehen.Particular preference is also given to using plastic film bags in which the plastic film front wall and the plastic film rear wall are welded together in the area of their first side edges in the section that lies below the first or second adhesive area, and in which the plastic film front wall and the plastic film rear wall are also in the area of the second side edges of which are welded together in that section which lies below the first or second adhesive area. Embodiments are also particularly suitable in which the plastic film front wall and the plastic film rear wall merge into one another at their respective upper edges, in particular in one piece, and in which the plastic film front wall and the plastic film rear wall merge into one another at their respective lower edges, in particular in one piece.
Die erfindungsgemäßen Kunststofffolienbeutel zeichnen sich in zweckmäßigen Ausgestaltungen insbesondere auch dadurch aus, dass die Kunststofffolienvorderwand und die Kunststofffolienrückwand an deren jeweiligen ersten Seitenrändern in demjenigen Abschnitt, nicht ineinander übergehen oder nicht miteinander verbunden vorliegen, der im Bereich des ersten oder zweiten Haftareals liegt und sich bis zum Beutelöffnungsrand erstreckt, und dass die Kunststofffolienvorderwand und die Kunststofffolienrückwand an deren jeweiligen zweiten Seitenrändern in demjenigen Abschnitt nicht ineinander übergehen oder nicht miteinander verbunden vorliegen, der im Bereich des ersten oder zweiten Haftareals liegt und sich bis zum Beutelöffnungsrand erstreckt. Hierbei bildet die Kunststofffolienvorderwand in dem Bereich von dem Beutelöffnungsrand in Richtung des Beutebodens, in dem die ersten und zweiten Seitenränder der Kunststofffolienvorderwand nicht mit den ersten und zweiten Seitenrändern der Kunststofffolienrückwand verbunden vorliegen oder nicht ineinander übergehen, bevorzugt eine Umklappverschlusslasche mit einer Breite (C) aus. Die Breite (C) stellt in diesem Fall die Ausdehnung der Umklappverschlusslasche quer zur Erstreckung zwischen den ersten und zweiten Seitenrändern von Kunststofffolienvorderwand und Kunststofffolienrückwand von dem Beutelöffnungsrand in Richtung des Beutelbodens dar.The plastic film bags according to the invention are characterized in expedient embodiments in particular by the fact that the plastic film front wall and the plastic film rear wall do not merge into one another or are not connected to one another on their respective first side edges in that section which is in the area of the first or second adhesive area and extends up to Bag opening edge extends, and that the plastic film front wall and the plastic film rear wall do not merge into one another or are not connected to one another at their respective second side edges in that section which lies in the area of the first or second adhesive area and extends to the bag opening edge. Here, the plastic film front wall preferably forms a fold-over closure tab with a width (C) in the area from the bag opening edge in the direction of the loot bottom, in which the first and second side edges of the plastic film front wall are not connected to the first and second side edges of the plastic film rear wall or do not merge into one another . The width (C) in this case represents the extent of the fold-over closure flap transversely to the extent between the first and second side edges of the plastic film front wall and plastic film rear wall from the bag opening edge in the direction of the bag bottom.
Solche erfindungsgemäßen Kunststofffolienbeutel lösen die der Erfindung zugrunde liegenden Aufgabe besonders zuverlässig, bei denen das zweite Haftareal im Bereich der Umklappverschlusslasche vorliegt oder bei denen das erste Haftareal auf der Innenseite der Kunststofffolienrückwand in einem Bereich vorliegt, der in Deckung mit der Umklappverschlusslasche bringbar ist. Zweckmäßigerweise ist die Breite (A) des ersten Haftareals oder die Breite (B) des zweiten Haftareals dabei regelmäßig kleiner oder gleich der Breite (C) der Umklappverschlusslasche.Such plastic film bags according to the invention solve the problem on which the invention is based particularly reliably, in which the second adhesive area is in the area of the fold-over closure tab or in which the first adhesive area is on the inside of the plastic film rear wall in an area that can be brought into alignment with the fold-over closure flap. The width (A) of the first adhesive area or the width (B) of the second adhesive area is expediently regularly smaller or equal to the width (C) of the fold-over closure tab.
Für viele Anwendungen hat es sich als besonders zweckmäßig erwiesen, dass das mindestens eine Verbindungsareal der erfindungsgemäßen Kunststofffolienbeutel eine Schweißnaht, insbesondere thermoplastische Schweißnaht, darstellt, das bzw. die sich von den ersten Seitenrändern von Kunststofffolienvorderwand und Kunststofffolienrückwand bis zu den zweiten Seitenrändern von Kunststofffolienvorderwand und Kunststofffolienrückwand erstreckt und die bevorzugt im Wesentlichen parallel, besonders bevorzugt parallel, zu dem Beutelöffnungsrand verläuft. Auf diese Weise wird der obere Abschnitt des Beutels, in den z.B. Grifflöcher eingearbeitet werden können, zuverlässig und sicher von dem unterem Beutelabschnitt, der die Beutelöffnung aufweist und der für die Aufnahme von Gegenständen vorgesehen ist, getrennt. Obwohl der erfindungsgemäße Kunststofffolienbeutel mit einem sehr geringen Materialeinsatz auskommt, erhält man auf diese Weise bereits ein sehr stabiles und gleichzeitig manipulationssicheres Transport- und Verpackungsgebinde.For many applications, it has proven to be particularly useful that the at least one connecting area of the plastic film bags according to the invention represents a weld seam, in particular a thermoplastic weld seam, which extends from the first side edges of the plastic film front wall and plastic film rear wall to the second side edges of the plastic film front wall and plastic film rear wall extends and which preferably runs essentially parallel, particularly preferably parallel, to the bag opening edge. In this way, the upper section of the bag, into which, for example, handle holes can be incorporated, is reliably and safely separated from the lower bag section, which has the bag opening and which is intended to hold objects. Although the plastic film bag according to the invention requires very little material, a very stable and at the same time tamper-proof transport and packaging container is obtained in this way.
Hierbei kann in bevorzugten Ausgestaltungen vorgesehen sein, dass das mindestens eine Verbindungsareal, insbesondere die Schweißnaht, bevorzugt thermoplastische Schweißnaht, näher beabstandet zu dem Beutelöffnungsrand als zu dem oberen Rand der Kunststofffolienvorderwand vorliegt, insbesondere benachbart zum Beutelöffnungsrand. Liegt die Schweißnaht, insbesondere thermoplastische Schweißnaht, benachbart zum Beutelöffnungsrand vor, befindet sich diese Schweißnaht pragmatischer Weise nicht in Deckung mit dem Beutelöffnungsrand, sie liegt dann vielmehr bevorzugt noch stets geringfügig beabstandet vor.In preferred embodiments, it can be provided that the at least one connection area, in particular the weld seam, preferably thermoplastic weld seam, is closer to the bag opening edge than to the upper edge of the plastic film front wall, in particular adjacent to the bag opening edge. If the weld seam, in particular a thermoplastic weld seam, is located adjacent to the bag opening edge, this weld seam is pragmatically not in line with the bag opening edge, but is then preferably always slightly spaced apart.
In einer weiteren bevorzugten Ausführungsform ist vorgesehen, dass das mindestens eine erste oder zweite Haftareal unterhalb des Beutelöffnungsrands, insbesondere benachbart zum Beutelöffnungsrand, angeordnet ist. Hierbei liegt der Folienabschnitt der Vorderwand, der mit dem Beutelöffnungsrand endet, flach auf der ebenfalls flach ausgelegten Rückwand an dessen Innenseite an.In a further preferred embodiment it is provided that the at least one first or second adhesive area is arranged below the bag opening edge, in particular adjacent to the bag opening edge. The film section of the front wall, which ends with the bag opening edge, lies flat on the inside of the rear wall, which is also flat.
Für den gattungsgemäßen Gebrauch des erfindungsgemäßen Kunststofffolienbeutels hat sich die Mitverwendung mindestens einer Haftmittelabdeckung, eingerichet und ausgelegt zur temporären Abdeckung des ersten oder zweiten Haftareals, als zweckmäßig erwiesen. Derartige abziehbare Schutzabdeckungen, die das frühzeitige Verkleben des Haftareals verhindern, sind dem Fachmann bekannt.For the generic use of the plastic film bag according to the invention, the use of at least one adhesive cover, set up and designed to temporarily cover the first or second adhesive area, has proven to be expedient. Such removable protective covers, which prevent the adhesive area from sticking together at an early stage, are known to those skilled in the art.
Zwecks Vereinfachung des Transports der erfindungsgemäßen Kunststofffolienbeutel kann vorgesehen sein, dass die Kunststofffolienvorderwand und die Kunststofffolienrückwand jeweils mindestens ein im Wesentlichen deckungsgleiches, insbesondere deckungsgleiches, Griffloch in dem Abschnitt zwischen dem Verbindungsareal und den oberen Rändern von Kunststofffolienvorderwand und Kunststofffolienrückwand aufweisen.In order to simplify the transport of the plastic film bags according to the invention, it can be provided that the plastic film front wall and the plastic film rear wall each have at least one essentially congruent, in particular congruent, handle hole in the section between the connecting area and the upper edges of the plastic film front wall and the plastic film rear wall.
Die Kunststofffolienvorderwand und/oder Kunststofffolienrückwand des Kunststofffolienbeutels können z.B. aus einem ein- oder mehrlagiges Folienmaterial gefertigt sein oder ein solches umfassen. Vielfach ist die Verwendung eines einlagigen Folienmaterials ausreichend.The plastic film front wall and/or plastic film rear wall of the plastic film bag can, for example, be made from or include a single or multi-layer film material. In many cases, the use of a single-layer film material is sufficient.
Dabei wird für das Folienmaterial von Kunststofffolienvorderwand und/oder, insbesondere und, Kunststofffolienrückwand insbesondere auf Polyolefine, bevorzugt Polyethylen und/oder Polypropylen und besonders bevorzugt HD-Polyethylen, zurückgegriffen.Polyolefins, preferably polyethylene and/or polypropylene and particularly preferably HD polyethylene, are used for the film material of the plastic film front wall and/or, in particular and, plastic film rear wall.
Das Folienmaterial von Kunststofffolienvorderwand und/oder, insbesondere und, Kunststofffolienrückwand kann in einer Ausführungsform auch transparent ausgestaltet sein.The film material of the plastic film front wall and/or, in particular and, plastic film rear wall can also be designed to be transparent in one embodiment.
Von besonderem Vorteil ist ferner, dass erfindungsgemäße Kunststofffolienbeutel zugänglich sind, bei denen Kunststofffolienvorderwand, der Beutelboden, z.B. als Falte oder Falz vorliegend, und die Kunststofffolienrückwand einstückig ausgebildet sind.It is also particularly advantageous that plastic film bags according to the invention are accessible in which the plastic film front wall, the bag bottom, for example in the form of a fold or fold, and the plastic film rear wall are formed in one piece.
Ferner können erfindungsgemäße Kunststofffolienbeutel mit mindestens einen Trageelement, insbesondere in Form einer Halteschlaufe oder eines Haltegriffs, ausgestattet sein.Furthermore, plastic film bags according to the invention can be equipped with at least one support element, in particular in the form of a holding loop or a handle.

- einem ersten Kunststofffolienvorderwandabschnitt, insbesondere enthaltend ein Griffloch,
- einem sich hieran, insbesondere einstückig, anschließenden Kunststofffolienrückwandabschnitt, insbesondere enthaltend ein Griffloch, und einem sich an diesen, insbesondere einstückig, anschließenden zweiten Kunststofffolienvorderwandabschnitt, enthaltend einen Beutelöffnungsrand, wobei die Länge des Kunststofffolienrückwandabschnitts größer oder gleich der kumulierten Länge von erstem Kunststofffolienvorderwandabschnitt und zweitem Kunststofffolienvorderwandabschnitt ist.
- a first plastic film front wall section, in particular containing a handle hole,
- a plastic film rear wall section adjoining this, in particular in one piece, in particular containing a handle hole, and one adjoining this, in particular in one piece, subsequent second plastic film front wall section, containing a bag opening edge, the length of the plastic film rear wall section being greater than or equal to the cumulative length of the first plastic film front wall section and the second plastic film front wall section.
Die erfindungsgemäßen Kunststofffolienbeutel eignen sich auch als, insbesondere manipulationssicheres, Transport- und/oder Verpackungsgebinde, insbesondere im Duty-free-Bereich oder als Tragetasche für Obst oder Gemüse.The plastic film bags according to the invention are also suitable as, in particular, tamper-proof, transport and/or packaging containers, particularly in the duty-free sector or as a carrying bag for fruit or vegetables.
Mit der vorliegenden Erfindung geht die überraschende Erkenntnis einher, dass Kunststofffolienbeutel auf sehr materialsparende Weise zugänglich sind und gleichwohl ein zuverlässiges Transport- und/oder Verpackungsgebinde liefern, das sogar als manipulationssicheres Transport- und/oder Verpackungsgebinde, z.B. für den Duty-free-Bereich, oder auch als Obst- oder Gemüsetragetasche eingesetzt werden kann.The present invention is accompanied by the surprising finding that plastic film bags are accessible in a very material-saving manner and nevertheless provide a reliable transport and/or packaging container that can even be used as a tamper-proof transport and/or packaging container, e.g. for the duty-free area. or can also be used as a fruit or vegetable carrier bag.
