Abstract

Gas-tight packages for enclosing solid articles such as chocolates and other non-perishable baked goods in the form of a tubular pouch package which is easily opened and can be stream lined wherein the pouch has a gas-tight envelope made of a flexible sheet-like packaging material provided with zones where the packaging material is doubled and with a tear-open means.

Description

Die Erfindung betrifft eine Öffnungshilfe aufweisende Packung mit einer gasdichten Packungshülle aus einem flächigen, insbesondere flexiblen Verpackungsmaterial, in welchem ein streifen-oder lappenförmiger Aufreißbereich vorgesehen ist, wobei das Verpackungsmaterial längs zumindest einem Teil der Berandung dieses Aufreißbereiches Durchstanzungen und/oder Schwächungslinienstücke aufweist und wobei beim Öffnen der Packung das Verpackungsmaterial längs zumindest einem Teil der Berandung des Aufreißbereiches aufreißt, und mit einem Abdeckelement aus flächigem Material, welches am Aufreißbereich über einen Teil seiner Fläche in lösbarer Weise mit dem Verpackungsmaterial verbunden ist.The invention relates to a package having an opening aid with a gas-tight packaging envelope made of a flat, in particular flexible packaging material, in which a strip-like or tab-shaped tear-open area is provided, the packaging material having punched-through and / or weakening line pieces along at least part of the edges of this tear-open area, and wherein When the package is opened, the packaging material tears open along at least part of the edge of the tear-open area, and with a cover element made of flat material, which is detachably connected to the packaging material at the tear-open area over part of its area.

Eine Packung dieser Art, die aus der EP-A-30348 bekannt ist, dient vorzugsweise zur Aufnahme von Tissus oder Gazestücken, die mit einer vorzugsweise erfrischenden oder desinfizierenden Flüssigkeit getränkt sind. Der im Verpackungsmaterial vorgesehene Aufreißbereich ist hier ein durch eine Perforationslinie völlig umschlossener, länglicher Bereich, während das Abdeckelement, das aus flächigem Material besteht, mit dem Verpackungsmaterial durch ein Bindemittel lösbar verbunden ist und den genannten länglichen Bereich dabei vollständig überdeckt. Das Abdeckelement ist ferner an einer seiner Rechteckseiten nahe einem Ende des Aufreißbereiches mit der Packungshülle zusätzlich in unlösbarer Weise durch eine streifenförmige Heißsiegelung verbunden. Beim Öffnen der Packung wird das Abdeckelement an seinem der Heißsiegelung entgegengesetzten Rand angefaßt und in Richtung auf die Heißsiegelung abgezogen, wobei das Verpackungsmaterial längs der den Aufreißereich umschließenden Perforationslinie einreißt und der längliche Abreißbereich, der an dem Abdeckelement haften bleibt, von diesem mitgenommen wird, so daß an der Stelle des Aufreißbereiches eine längliche Öffnung in der Packungshülle freigegeben wird. Das Abdeckelement samt dem an ihm haftenden Aufreißbereich, das über die streifenförmige Heißsiegelung mit der Packungshülle wie an einem Scharnier verbunden bleibt, kann nach einer Entnahme vom Verpackungsgut für ein Wiederverschließen in seine ursprüngliche Lage geklappt und durch Andrücken die lösbare Verbindung wieder hergestellt werden. Eine im wesentlichen nach demselben Prinzip arbeitende Öffnungshilfe mit Wiederverschließbarkeit ist ferner auch aus der US-A-3 711 011 für einen beutelförmigen Behälter bekannt.A pack of this type, which is known from EP-A-30348, is preferably used to hold tissues or gauze pieces soaked in a preferably refreshing or disinfectant liquid. The tear-open area provided in the packaging material is here an elongated area which is completely enclosed by a perforation line, while the cover element, which consists of flat material, is detachably connected to the packaging material by a binder and completely covers the said elongated area. The cover element is also inseparably connected on one of its rectangular sides near one end of the tear-open area to the packing envelope by a strip-shaped heat seal. When the package is opened, the cover element is gripped at its edge opposite the heat seal and pulled off in the direction of the heat seal, the packaging material tearing along the perforation line surrounding the tear-open area and the elongated tear-off area which remains adhering to the cover element being carried away by it that an elongated opening in the packaging envelope is opened at the location of the tear-open area. The cover element together with the tear-open area adhering to it, which remains connected to the packaging sleeve like a hinge via the strip-shaped heat seal, can be folded back into its original position after removal from the packaged goods for reclosing and the releasable connection can be restored by pressing. An opening aid with resealability, which operates essentially on the same principle, is also known from US-A-3,711,011 for a bag-shaped container.

Die Erfindung, wie sie in den Patentansprüchen gekennzeichnet ist, löst die Aufgabe, eine Packung der eingangs genannten Art anzugeben, bei der das Verpackungsmaterial beim Öffnen an der Berandung eines streifen- oder lappenförmigen Aufreißbereiches einreißt, der sich bei relativ kleinem für die Öffnungshilfe erforderlichen Materialaufwand über einen relativ großen Bereich der Packung erstrecken können soll, und die besonders einfach herstellbar ist.The invention, as characterized in the claims, solves the problem of specifying a pack of the type mentioned, in which the packaging material tears when opened at the edge of a strip or tab-shaped tear-open area, which tends to be relatively small in terms of the material required for the opening aid should be able to extend over a relatively large area of the pack, and which is particularly easy to produce.

Nach Anspruch 1 ist die erfindungsgemäße Packung dadurch gekennzeichnet, daß der mit dem Verpackungsmaterial flächig verbundene Oberflächenbereich des Abdeckelementes eine äußere Kontur aufweist, die nur einen Teilbereich des streifen- oder lappenförmigen Aufreißbereiches an dessen Anfang umschließt und die im Falle einer Durchstanzung diese völlig umschließt, sie dabei aber nicht berührt.According to claim 1, the package according to the invention is characterized in that the surface area of the cover element which is connected to the packaging material in a flat manner has an outer contour which surrounds only a partial area of the strip-like or tab-shaped tear-open area at the beginning thereof and which completely surrounds it in the event of a punching but not touched.

Aus der US-A-3 302 856 ist zwar eine als Abdeckung für einen Plastikbehälter dienende axial verstreckte Polyolefinfolie bekannt, die über einen dreieckförmigen Bereich, von dem eine der Dreiecksseiten senkrecht zur Folien-Verstreckungsrichtung verläuft, durch Heißsiegelung mit einer Aufreißlasche verbunden ist. Wird die Aufreißlasche nun von der Dreiecksmitte aus gesehen parallel zur Folien-Verstreckungsrichtung in Richtung auf die genannte Dreiecksseite gezogen, reißt diese Polyolefinfolle zunächst von einer Ecke des Dreiecks ausgehend längs zwei Dreiecksseiten ein, wonach - außerhalb dieser dreiecksförmigen Siegelverbindung - die Polyolefinfolie längs zwei zueinander parallelen und seitlich einem Aufreißstreifen begrenzenden Linien in Folien-Verstreckungsrichtung weiterreißt. Die aus dieser US-A-3 302 856 bekannte Öffnungshilfe ist aber nur für ein Verpackungsmaterial einzusetzen, das aus einer heißsigelfähigen Folie aus axial verstrecktem Kunststoff, insbesondere axial verstreckten Thermoplasten besteht und ist demzufolge in seiner Anwendungsmöglichkeit beschränkt.From US-A-3 302 856, an axially stretched polyolefin film serving as a cover for a plastic container is known, which is heat-sealed to a tear-open tab over a triangular area, one of the triangular sides of which extends perpendicular to the film stretching direction. If the tear-open tab is now seen from the center of the triangle parallel to the film stretching direction in the direction of the triangle side mentioned, this polyolefin roll first tears along two triangle sides starting from a corner of the triangle, after which - outside of this triangular sealing connection - the polyolefin film along two parallel to one another and tears along the lines delimiting a tear strip in the film stretching direction. However, the opening aid known from this US Pat. No. 3,302,856 is only to be used for a packaging material which consists of a heat-sealable film made of axially stretched plastic, in particular axially stretched thermoplastics, and is therefore limited in its possible application.

Anhand der Figuren erfolgt nun die Erläuterung einiger vorteilhafter Ausführungswege der Erfindung.Some advantageous embodiments of the invention are now explained on the basis of the figures.

Für die anhand der Figuren 1 und 2 beschriebenen Packungen geht man beispielsweise von einem mehrlagigen Verpackungsmaterial aus, das eine an der Packungsaußenseite zu liegen kommende Trägerschicht aus einem getrichenen Kraftpapier einer Grammatur von 50-70 glm2, eine an diese ankaschierte 0,009 mm starke Aluminiumfolie als gasdichte Schicht und daran anschließend eine Siegelmediumschicht aufweist. Je nach Art der durchzuführenden Siegelung besteht die Siegelmediumschicht vorteilhaft aus einem Heißsiegelmedium, wie einer PE- oder PVDC- oder Hotmelt - Beschichtung, einer Stärke von 0,02 bis 0,06 mm oder einer Kaltkleberbeschichtung auf Latex-basis mit einem Auftrag von 2-7 g/m2 (Feststoff).For the packs described with reference to FIGS. 1 and 2, it is assumed, for example, that there is a multilayer packaging material which is a carrier layer to be located on the outside of the pack made of coated kraft paper with a grammage of 50-70 glm 2 , a 0.009 mm thick aluminum foil laminated to it gas-tight layer and then has a sealing medium layer. Depending on the type of sealing to be carried out, the sealing medium layer advantageously consists of a heat sealing medium, such as a PE or PVDC or hotmelt coating, a thickness of 0.02 to 0.06 mm or a cold adhesive coating based on latex with an application of 2- 7 g / m 2 (solid).

Fig. 1 zeigt in perspektivischer Darstellung eine Schlauchbeutelpackung 1 deren Verpackungsmaterial zwei Schwächungslinien 2 aufweist, welche an ihren Enden durch eine im Verpackungsmaterial angebrachte linienförmige Durchstanzung 3 miteinander verbunden sind, derart, daß diese Schwächungslinien 2 und die Durchstanzung 3 einen Aufreißbereich 4 begrenzen.1 shows a perspective view of a tubular bag pack 1, the packaging material of which has two weakening lines 2, which are connected at their ends by a line-shaped punching 3 provided in the packaging material, such that these weakening lines 2 and the punching 3rd limit a tear area 4.

Im Bereich dieser Durchstanzung ist das Verpackungsmaterial mit einem flächenhaften Abdeckelement 5 (das in Fig. 1 aus Gründen der Übersichtlichkeit mit übertrieben großer Dicke dargestellt ist) in lösbarer Weise über einen Bereich 6 der Abdeckelementoberfläche verklebt, wobei die äußere Kontur 7 dieses Oberflächenbereichs 6 die Durchstanzung 3 völlig umschließt, diese aber nicht berührt. Durch das Abdeckelement 5 wird die Durchstanzung 3, welche eine Öffnung im Verpackungsmaterial darstellt, gasdicht verschlossen. Zur Erzielung einer ausreichenden Gasdichtheit beträgt der Mindestabstand der Kontur 7 von der Durchstanzung 3 dabei etwa 5 mm. Das Abdeckelement 5, das z. B. vorteilhaft eine Klebeetikette sein kann, ist ferner an einem Randbereich 8, der den ablaufenden Schwächungslinien gegenüberliegt, mit dem Verpackungsmaterial nicht verklebt.In the area of this punching, the packaging material is detachably glued to a surface covering element 5 (which is shown in FIG. 1 with an exaggerated thickness for clarity) over an area 6 of the covering element surface, the outer contour 7 of this surface area 6 being punched through 3 completely encloses, but does not touch them. The punching 3, which represents an opening in the packaging material, is closed gas-tight by the cover element 5. To achieve sufficient gas tightness, the minimum distance of the contour 7 from the punching 3 is about 5 mm. The cover element 5, the z. B. can advantageously be an adhesive label, is also not glued to an edge region 8, which lies opposite the running lines of weakness, with the packaging material.

Beim Aufreißen der Packung wird das Abdeckelement 5 an seinem Randbereich 8 angefaßt und in Richtung des Pfeiles 9 zunächst vom Verpackungsmaterial abgezogen und dann dem Aufreißbereich 4 entlanggeführt. Das Abdeckelement 5 löst sich dabei nicht vom Aufreißbereichanfang 10, so daß die Packung in üblicher Weise durch Einreißen der Schwächungslinien 2 geöffnet wird. Dabei wird infolge der U-förmigen Durchstanzung 3 bewirkt, daß beim Aufreißvorgang dem Abziehen des Aufreißbereiches 4 kein stärkerer Widerstand entgegensteht und das Einreißen des Verpackungsmaterials an seinen Schwächungslinien 2 zügig und mit geringem Kraftaufwand ausgeführt werden kann.When the package is torn open, the cover element 5 is gripped at its edge region 8 and first pulled off from the packaging material in the direction of arrow 9 and then guided along the tearing region 4. The cover element 5 does not detach from the opening area 10, so that the package is opened in the usual way by tearing the lines of weakness 2. As a result of the U-shaped punching 3, there is no greater resistance to the pulling off of the tearing area 4 during the tearing process and the tearing of the packaging material on its weakening lines 2 can be carried out quickly and with little effort.

In manchen Fällen kann nun aber statt der die beiden Schwächungslinien 2 verbindenden linienförmigen Durchstanzung ein insbesondere durch eine Anstanzung realisiertes Schwächungslinienstück vorgesehen werden. Dabei kommt es darauf an, daß die Adhäsion der flächigen Verbindung, mit der das Abdeckelement mit dem Anfang des Aufreißstreifens verbunden ist, groß genug ist, um die Kraft, die zum Aufreißen des Verpackungsmaterials an den die beiden Schwächungslinien 2 verbindenden Schwächungslinienstücke benötigt wird, zu übertragen. Da bei diesen Packungsvarianten keine Durchstanzung vorgesehen ist, verliert das Abdeckelement seine Dichtungsfunktion und es genügt, wenn das Abdeckelement ausschließlich im Aufreißbereich-Anfang mit dem Verpackungsmaterial flächig verbunden ist.In some cases, instead of the line-shaped punching that connects the two weakening lines 2, a piece of weakening line that is realized in particular by punching can be provided. It is important that the adhesion of the flat connection with which the cover element is connected to the start of the tear strip is large enough to the force required to tear the packaging material on the pieces of weakening line connecting the two lines of weakness 2 transfer. Since no punching is provided in these pack variants, the cover element loses its sealing function and it is sufficient if the cover element is connected to the packaging material only at the beginning of the tear-open area.

Fig. 2 zeigt eine Schauchbeutelpackung 11, die analog wie die Packung gemäß Fig. 1 einen Aufreißbereich 14 aufweist, der von Schwächungslinien 12 und einer diese Schwächungslinien verbindenden Durchstanzung 13 begrenzt wird. Bei dieser Packungsvariante ist nun ein flächiges Abdeckelement 15 im Bereich der Durchstanzung 13 auf der Innenseite des Verpackungsmaterials aufgeklebt. Der bei dieser Verklebung mit dem Verpackungsmaterial flächig verbundene Oberflächenbereich 16 des Abdeckelements 15 ist fensterförmig ausgebildet, d. h. er weist neben einer äußeren Kontur 17 eine die Fensteröffnung begrenzende innere Kontur 18 auf, innerhalb der das Abdeckelement 15 mit dem Verpackungsmaterial nicht verklebt ist. Der Mindestabstand dieser inneren Kontur 18 von der äußeren Kontur 17 beträgt dabei etwa 5 mm. Durch das Abdeckelement 15 ist nun in ähnlicher Weise wie bei der Packung gemäß Fig. 1 die durch die Durchstanzung 13 gebildete Öffnung im Verpackungsmaterial gasdicht verschlossen. Da bei der vorliegenden Packung gemäß Fig. 2 das Abdeckelement 15 im Bereich der Durchstanzung 13 nicht mit dem Verpackungsmaterial verklebt ist, bildet der Aufreißbereich-Anfang 20 einen leicht abhebbaren Verpackungsmateriallappen.FIG. 2 shows a tubular bag pack 11 which, like the pack according to FIG. 1, has a tear-open area 14 which is delimited by weakening lines 12 and a punching 13 connecting these weakening lines. In this packaging variant, a flat covering element 15 is now glued in the area of the punching 13 on the inside of the packaging material. The surface area 16 of the cover element 15 which is connected flatly to the packaging material during this bonding is window-shaped, i. H. in addition to an outer contour 17, it has an inner contour 18 delimiting the window opening, within which the cover element 15 is not glued to the packaging material. The minimum distance of this inner contour 18 from the outer contour 17 is about 5 mm. Through the cover element 15, the opening formed by the punching 13 in the packaging material is now closed in a gas-tight manner in a manner similar to the packing according to FIG. 1. Since the cover element 15 in the present punching according to FIG. 2 is not glued to the packaging material in the area of the punching 13, the tear-off area beginning 20 forms an easily removable packaging material flap.

Beim Aufreißen der Packung wird der Aufreißbereich 14 an seinem Anfang 20 angefaßt und unter Einreißung der Schwächungslinien 12 und Ablösung von dem an der Verpackungsmaterialinnenseite angebrachten Abdeckelement 15 in Richtung des Pfeiles 19 abgezogen.When the package is torn open, the tear-open area 14 is grasped at its beginning 20 and, in the direction of the arrow 19, is pulled off by tearing the lines of weakness 12 and detaching it from the cover element 15 attached to the inside of the packaging material.

An den beiden anhand der Figuren 1 und 2 beschriebenen Packungsvarianten nehmen die Aufreißbereiche jeweils einen relativ großen Teil der Packungsfrontoberfläche ein.In the case of the two packaging variants described with reference to FIGS. 1 and 2, the tear-open areas each occupy a relatively large part of the surface of the packaging front.

Um diese Aufreißhilfen aus ästhetischen Gründen bzw. zum Schutz gegen etwaige mechanische Beschädigungen abzudecken, kann der prismaförmige Hüllenbereich dieser Packungen vorteilhaft mit einer nachträglich angebrachten hülsenförmigen Schleife aus flächigem Material, wie Papier, versehen werden. Auf diese Schleife wird dann - unbeeinträchtigt durch die Ausbildung der Aufreißhilfe - die äußere Aufmachung der Packung angebracht. Es kann aber auch bei einer Packung wie nach Fig. 1 die hülsenförmige Schleife vorteilhaft so ausgebildet sein, daß sie gleichzeitig das Abdeckelement bildet.In order to cover these tear-open aids for aesthetic reasons or to protect against any mechanical damage, the prism-shaped envelope area of these packs can advantageously be provided with a subsequently attached sleeve-shaped loop made of sheet material, such as paper. The outer packaging of the pack is then attached to this loop, unaffected by the design of the tear-open aid. 1, the sleeve-shaped loop can advantageously also be designed such that it forms the cover element at the same time.

Es hat sich gezeigt, daß das Aufreißorgan der erfindungsgemäßen Packung in vielen Fällen auch dann in gut reproduzierbarer Weise funktioniert, wenn der Aufreißbereich seitlich nicht durch Schwächungslinien begrenzt ist. In diesen Fällen reißt das Verpackungsmaterial von den beiden Enden der Durchstanzung ausgehend längs zwei im wesentlichen parallel bzw. leicht konvergierenden oder leicht divergierenden Linien ein. Dies ist z. B. der Fall, wenn das Verpackungsmaterial aus bestimmten einlagigen Materialien wie Papier, einem biaxial gereckten Polypropylen (OPP) oder einer Aluminiumfolie besteht. Beim Einsatz von mehrlagigen Verpackungsmaterialien, wie sie bevorzugt zum Aufbau von gasdichten Packungen, wie Schlauchbeutelpackungen verwendet werden, zeigt sich aber ein differenziertes Einreißverhalten.It has been shown that the tear-open member of the package according to the invention in many cases also functions in a reproducible manner if the tear-open area is not laterally limited by lines of weakness. In these cases, the packaging material tears from the two ends of the punching along two substantially parallel or slightly converging or slightly diverging lines. This is e.g. B. the case when the packaging material consists of certain single-layer materials such as paper, a biaxially oriented polypropylene (OPP) or an aluminum foil. When using multi-layer packaging materials, as they are preferably used to build gas-tight packs, such as tubular bag packs, there is a differentiated tear behavior.

Bei Verpackungsmaterialien, die eine Trägerschicht und eine mit dieser verbundenen gasdichten Schicht aus einem homogenen, gasdichten, jedoch gut einreißfähigem Material aufweisen, welche Schichten bei der Herstellung durch bahnenförmige Lagen gebildet werden, zeigt sich - insbesondere bei einem raschen Aufreißen der Packungen - in der Regel nur dann ein gut reproduzierendes, nicht zu stark divergierendes oder keilförmig zusammenlaufendes Einreißen des Verpackungsmaterials, wenn das Trägermaterial dem Packungsgut zugewandt ist.In the case of packaging materials which have a carrier layer and a gas-tight layer connected therewith from a homogeneous, gas-tight but easily tearable material, which layers are formed in the form of web-shaped layers, it becomes apparent - particularly when the sheets are torn open quickly Packs - usually only a well reproducing, not too divergent or wedge-shaped tearing of the packaging material when the carrier material is facing the packaged goods.

Ein solches Verpackungsmaterial, welches dreischichtig aufgebaut ist, besteht z. B. - von der Packungsaußenseite ausgehend - aus einer 0,0-12 bis 0,020 mm starken Folie aus biaxial gerecktem Polypropylen (OPP), einer 0,009 mm starken Aluminiumfolie, einem Kraftpapier einer Grammatur von 40-60 g/m2 und einer Kaltkleberbeschichtung auf Latexbasis (2-7 g/m2 Feststoff).Such packaging material, which is constructed in three layers, consists, for. B. - starting from the outside of the pack - from a 0.0-12 to 0.020 mm thick film made of biaxially oriented polypropylene (OPP), a 0.009 mm thick aluminum film, a kraft paper with a grammage of 40-60 g / m 2 and a cold adhesive coating Latex base (2-7 g / m 2 solid).

Die Fig. 3 zeigt in perspektivischer Darstellung eine z. B. mit einem solchen Verpackungsmaterial hergestellte, als Schlauchbeutelpackung ausgebildete erfindungsgemäße Packung, bei der keine Schwächungslinien vorgesehen sind.Fig. 3 shows a perspective view of a z. B. produced with such a packaging material, designed as a tubular bag pack according to the invention, in which no lines of weakness are provided.

Das Verpackungsmaterial weist hier eine U-förmige Durchstanzung 33 auf, die mit einer partiell mit Klebstoff beschichteten Klebeetikette als Abdeckelement 25 wieder verschlossen ist. Die äußere Kontur 27 des Klebebereiches 26 des Abdeckelementes 25 umschließt dabei die Durchstanzung 23 völlig, ohne sie jedoch zu berühren. Das Abdeckelement 25 weist ferner einen Randbereich 28 auf, mit dem es mit dem Verpackungsmaterial nicht verbunden ist.The packaging material here has a U-shaped punching 33, which is closed again as a covering element 25 with an adhesive label partially coated with adhesive. The outer contour 27 of the adhesive area 26 of the cover element 25 completely surrounds the punched hole 23 without, however, touching it. The cover element 25 also has an edge region 28 with which it is not connected to the packaging material.

Beim Aufreißen der Packung wird das Abdeckelement 25 angefaßt und in Richtung des Pfeiles 29 abgezogen. Dabei reißt das Verpackungsmaterial längs zwei zueinander angenähert parallel verlaufenden Linien, die den Aufreißbereich 24 zu beiden Seiten begrenzen, ein. Fig. 4 zeigt die Packung während des Aufreißvorganges in einer Teildarstellung im Schnitt. Verwendet man bei einer Packung gemäß den Figuren 3 und 4 hingegen ein Verpackungsmaterial, welches - von außen nach innen - eine OPP-Folle, ein Kraftpapier, eine Aluminiumfolie und schließlich die Kaltkleberbeschichtung (jeweils z. B. in den Einzelstärken wie im Zusammenhang mit Fig. 3 angegeben) aufweist, so laufen - insbesondere bei einem raschen Aufreißen der Packung - die Einreißlinien keilförmig zusammen, so daß sich keine zur Entnahme von Verpackungsgut brauchbare Öffnung bildet.When the package is torn open, the cover element 25 is gripped and pulled off in the direction of the arrow 29. The packaging material tears along two lines running approximately parallel to one another and delimiting the tear-open area 24 on both sides. Fig. 4 shows the package during the tearing process in a partial representation in section. If, on the other hand, a packaging according to FIGS. 3 and 4 is used, a packaging material which - from the outside inwards - contains an OPP sheet, a kraft paper, an aluminum foil and finally the cold adhesive coating (in each case e.g. in the individual thicknesses in connection with 3 indicated), the tearing lines run together in a wedge shape, particularly when the package is torn open quickly, so that no opening that can be used to remove packaging material is formed.

Ein zweilagiges Verpackungsmaterial, das für erfindungsgemäße Packungen, welche ohne den Aufreißbereich seitlich begrenzende Schwächungslinien auskommen, geeignet ist, besteht außerdem z. B. - von außen nach innen - aus einer Aluminiumfolie, einem gestrichenen Kraftpapier und der Kaltkleberbeschichtung, und zwar jeweils mit Einzelstärken, wie sie z. B. bei dem im Zusammenhang mit den Figuren 1 und 2 verwendeten Verpackungsmaterial angegeben sind.A two-ply packaging material, which is suitable for packs according to the invention, which do not require weakening lines that laterally delimit the tear-open area, also consists, for. B. - from the outside to the inside - from an aluminum foil, a coated kraft paper and the cold adhesive coating, each with individual thicknesses such as z. B. are specified in the packaging material used in connection with Figures 1 and 2.

Andere geeignete zweilagige Verpackungsmaterialien bestehen z. B. - jeweils von außen nach innen - aus einer 0,012 bis 0,030 mm starken OPP-Folie, einer 0,02 bis 0,04 mm starken PE-Folie und einer Kaltkleberbeschichtung oder aus einer 0,009 mm starken Aluminiumfolie, einer 0,02-0,03 mm starken OPP-Folie und der Kaltkleberbeschichtung.
