Description

Vorliegende Erfindung betrifft eine Verpackung mit Siegelrändern und geschwächten Zonen als Aufreisshilfe aus einem folienförmigen, mehrlagigen Verbundmaterial gemäss dem Oberbegriff von Anspruch 1 sowie ein Verfahren zur Herstellung der Verpackung, ferner Mittel zur Herstellung der Verpackung und die Verwendung der Packung.The present invention relates to a package with sealing edges and weakened zones as a tear-open from a film-shaped, multilayer composite material according to the preamble of claim 1 and a Method for producing the packaging, further means for producing the packaging and the use of the pack.

Es sind beispielsweise Siegelrandbeutel bekannt, die zum Verpacken von pulverförmigen oder festen Füllgütern vorgesehen sind. Typische Füllgüter können aus dem Bereich der Nahrungs- und Genussmittel sein, wie pulverförmiger sofortlöslicher Kaffee oder Schokladeriegel, Milchspeisen, wie Yoghurt, und dergl. Die Verpackungen müssen das Füllgut vor mechanischen, chemischen und physikalischen Einflüssen schützen. Deshalb sind solche Verpackungen in vielen Fällen aus mehrlagigem Verpackungsmaterial gefertigt, wobei einzelnen Materiallagen oder einer Materiallagenkombination eine spezifische Schutzfunktion zugeordnet werden kann. Das Verpackungsmaterial muss beispielsweise reissfest sein. Dies bedingt sehr dehnbare oder verstreckbare Materialien hoher struktureller Festigkeit. Das Öffnen einer Verpackung aus solchen Materialien gestaltet sich schwierig und ist ohne Zuhilfenahme einer Schere oder eines Messers nicht zu bewerkstelligen. Zur Erleichterung des Öffnens ohne ein Werkzeug werden deshalb regelmässig Aufreisshilfen an der Verpakkung angebracht. Eine Anreisshilfe kann beispielsweise eine Kerbe am äusseren Rand der Siegelnaht sein. Das Material einer derart ausgerüsteten Verpackung lässt sich sehr leicht anreissen, beim Weiterreissen durch die Beutelwandung lässt sich die Reissrichtung nicht mehr kontrollieren und die entstehende Öffnung ist oft unvollständig oder führt mitten durch eine Seitenwand. Das Anbringen der Anreisshilfe muss in der Verpackungsmaschine erfolgen. Dies reduziert die Betriebsgeschwindigkeit der Verpackungsmaschine. In vielen Fällen versucht man die Nachteile dadurch zu beheben, dass ein Aufreissstreifen zwischen zwei Materiallagen gelegt wird und durch Ziehen am Aufreissstreifen eine Teilung des Verpakkungsmaterials erreicht wird. Die entstehende Öffnung ist klar definiert, jedoch ist die Herstellung dieser Aufreisshilfe aufwendig und führt zu unflexiblen Fabrikationsprozessen. There are, for example, sealed edge pouches known for the packaging of powdery or solid contents are provided. Typical products can be found in the field of Foodstuffs, such as powdered instant coffee or chocolate toppings, Dairy foods, such as yoghurt, and the like. The packaging must contain the contents Protect mechanical, chemical and physical influences. That's why they are Packaging in many cases made of multi-layer packaging material, with individual Material layers or a material layer combination a specific protective function can be assigned. The packaging material, for example, must be tear-resistant. This conditionally very ductile or stretchable materials of high structural strength. The Opening a package made of such materials is difficult and is without Can not be done with the help of scissors or a knife. To make things easier Therefore, when opening without a tool, it will regularly tear open the packaging appropriate. A Anreißhilfe can, for example, a notch on the outer edge of the Be sealed seam. The material of such a package is very easy tear, when tearing through the bag wall, the direction of travel can not control more and the resulting opening is often incomplete or performs right through a side wall. The attachment of the marking aid must take place in the packaging machine. This reduces the operating speed of the packaging machine. In many cases one tries to remedy the disadvantages by having a tear strip between two Laying material layers is laid and by pulling the tear strip a division of Verpakkungsmaterials is reached. The resulting opening is clearly defined, but the manufacturing is This tearing aid consuming and leads to inflexible manufacturing processes.

Die FR-A-2 717 449 offenbart eine Verpackung gemäss dem Oberbegriff von Anspruch 1 (vgl. Anspruch 1; Seite 5, Zeile 15 bis Seite 6, Zeile 8; Seite 8, Zeilen 15 bis 32; Seite 10, Zeile 33 bis Seite 11, Zeile 9; Fig. 1 bis 3). Dabei sind die geschwächten Zonen in Form von Mikroporen ausgebildet.FR-A-2 717 449 discloses a package according to the preamble of claim 1 (see claim 1, page 5, line 15 to page 6, line 8, page 8, lines 15 to 32, page 10, Line 33 to page 11, line 9; Fig. 1 to 3). The weakened zones are in the form of Micropores formed.

Die EP-A-0 521 618 beschreibt eine Beutelverpackung mit geschwächten Zonen als Aufreisshilfe in wenigstens einer Materiallage ausserhalb des Füllraumes in Form von nicht näher definierten Diskontinuitäten (vgl. Spalte 3, Zeilen 41 bis 55; Fig. 2 und 3). EP-A-0 521 618 describes a bag package with weakened zones as a breakdown aid in at least one material layer outside the filling space in the form of not closer Defined discontinuities (see column 3, lines 41 to 55, Fig. 2 and 3).

    Das Verbundmaterial weist geschwächte Zonen in wenigstens einer Materiallage des Verbundmaterials auf. Vorzugsweise sind die geschwächten Zonen an der ersten Materiallage des Verbundmaterials vorgesehen. Es ist auch möglich, die geschwächten Zonen an der zweiten Materiallage oder an der ersten und der zweiten Materiallage des Verbundmaterials vorzusehen. In letzterem Fall ist es vorteilhaft, dass die geschwächten Zonen der ersten Materiallage und der zweiten Materiallage am Verbundmaterial nicht übereinander, sondern versetzt zueinander, angeordnet sind. Geschwächte Zonen sind erfindungsgemäss Schnittfolgen oder eine Vielzahl von Einzelschnitten in paralleler Anordnung. Die Schnittrichtung verläuft dabei in Reissrichtung. Beispielsweise können die Abstände der Schnitte 0,1 bis 1mm, die Länge der Schnitte 1 bis 50 mm und die Anzahl der Schnitte je geschwächte Zone kann 2 bis 50 betragen. Die geschwächten Zonen können sich nur über dem Füllraum einer Verpackung befinden oder können sich über dem Füllraum befinden und sich bis innerhalb einer gesiegelten Rand- oder Seitennaht erstrecken. Die Materiallage oder Materiallagen mit den geschwächten Zonen stellt an einer Verpackung vorteilhaft eine aussenliegende oder nach aussen weisende Schicht des Verbundmaterials dar.The composite material has weakened zones in at least one layer of material of the composite material on. Preferably, the weakened zones are at the first material layer provided the composite material. It is also possible to weaken the zones at the second material layer or at the first and the second material layer of the composite material provided. In the latter case, it is advantageous that the weakened zones of the first material layer and the second material layer on the composite material are not superimposed, but offset from one another, are arranged. Weakened zones are according to the invention Cutting sequences or a variety of single cuts in parallel Arrangement. The cutting direction runs in the direction of travel. For example, you can the distances of the cuts 0.1 to 1mm, the length of the cuts 1 to 50 mm and the number of cuts per weakened zone can be 2 to 50.

Geeignete Druckverfahren sind beispielsweise Buch-, Offset-, Flexo-, Sieb- und Kupfertiefdruck. Im Bereich der Druckmaschine, vor, zwischen zwei Farbaufträgen oder nach dem Druckfarbenauftrag kann die erste Materiallage geschwächt werden. Die geschwächten Zonen können durch Anbringen von Schwächungen oder Durchtrennungen erzeugt werden. Dies kann mechanisch, beispielsweise durch Messer, wie oszillierende Messer, an einem Zylinder angebrachte rotierende Messer, Stanzmesser oder Nadeln usw. erfolgen. Andere Vorrichtungen zum Anbringen der geschwächten Zonen sind energiereiche Strahlungen, wie Laserstrahlen oder Elektronenstrahlen. Solche Verfahren führen in der Regel zu Mikroperforationen. Die Schwächungen werden im Register, d.h. synchron, mit der Bedruckung, an der ersten Materiallage angebracht. Dies ermöglicht eine genaue Ausrichtung der Schwächung, gleichzeitig mit der genauen Ausrichtung der Bedruckung auf dem Verpackungsmaterial. Es ist auch möglich, die Schwächung zu Beginn oder im Laufe des Druckfarbenauftrages oder vor einem allenfalls vorgesehenen Lack- oder Schutzlackauftrag durchzuführen. Die Schwächung wird dann durch die Druckfarben und/oder den Lack oder Schutzlack überdeckt. Damit wird u.a. eine Barrierewirkung gegen einen Stoffaustausch von Feuchtigkeit, Gasen etc. beispielsweise durch die Öffungen einer Perforation oder eines Schnittes erreicht. Gleichzeitig kann die geschwächte Zone bezüglich der Reissfestigkeit stabilisiert werden, ohne das gewollte Aufreissen zu erschweren. Vorzugsweise werden die Druck- und Schwächungsverfahren an Endlos- oder Rollenware kontinuierlich durchgeführt, die Behandlung von Blättern oder Bogen ist ebenfalls möglich.The present invention also relates to a method of attaching the weakened zones on the composite material according to the characterizing part of claim 7. The composite material is produced by the provision of the first Material situation, occasionally the one- or two-sided printing of the first material layer and simultaneously applying the weakened zones in the register. Suitable printing methods are for example book, offset, flexo, screen and copper gravure printing. Around Printing machine, before, between two color orders or after the ink application can weaken the first material situation. The weakened zones can be attached by attaching from weakening or severing. This can be mechanical, for example by knives, such as oscillating knives, mounted on a cylinder rotating Knife, punch or needles, etc. done. Other devices for attachment The weakened zones are high-energy radiations, such as laser beams or electron beams. Such methods usually lead to microperforations. The weakenings are stored in the register, i. synchronously, with the printing, on the first material layer appropriate. This allows a precise alignment of the weakening, simultaneously with the precise alignment of the printing on the packaging material. It is also possible, the weakening at the beginning or in the course of the ink application or before a if necessary, apply varnish or protective varnish. The weakening will then covered by the printing inks and / or the paint or protective varnish. This will u.a. a barrier effect against a mass transfer of moisture, gases, etc., for example achieved through the openings of a perforation or a cut. simultaneously The weakened zone can be stabilized with respect to tear strength without the wanted Complicating tearing up. Preferably, the pressure and Weakening process on continuous or roll goods continuously carried out the treatment of leaves or bow is also possible.
