Abstract

A multi-layer sack comprises at least one outer (1) and at least one inner (5) paper layer with a plastic layer (2) between them. There is an overlap of the outer breadth and partial overlap of the plastic at the long side and the outer layer is partially stuck (3) to itself in the overlap region.

Description

Die Erfindung betrifft einen mehrlagigen Sack bestehend aus Papier, der an seiner Innenseite eine Folienbahn aufweist, und einen verbesserten Schutz des Verpackungsguts gegen Feuchtigkeit, sowie eine verbesserte Entlüftung beim Befüllen aufweist.The invention relates to a multilayer bag consisting of paper, which has on its inner side a film web, and improved protection of the packaged goods against moisture, as well as improved ventilation during filling.

Zur Erzielung eines guten Feuchtigkeitsschutzes von feuchtigkeitsempfindlichen Gütern weisen Papiersäcke häufig Kunststofffolien als Innenlage, bzw. zwischen zwei Papierlagen auf.
Um eine ausreichende Luftdurchlässigkeit bzw. Entlüftung beim Befüllen des Sacks zu gewährleisten, wird die Kunststofffolie entweder mit Durchbrechungen versehen, bzw. genadelt oder perforiert.To achieve a good moisture protection of moisture-sensitive goods, paper sacks often have plastic films as an inner layer or between two paper layers.
In order to ensure sufficient air permeability or ventilation when filling the bag, the plastic film is either provided with perforations, or needled or perforated.

Aus der EP 0 867 379 A1 ist ein perforierter Sack bekannt, wobei eine Perforierung durch alle Lagen des Sacks erfolgt. Dadurch wird zwar eine ausreichende Luftdurchlässigkeit gewährleistet, der Schutz gegen Feuchtigkeit ist aber nicht mehr zuverlässig gegeben. Ferner ist ein derartiger Sack nicht mehr zur Aufnahme von pulverförmigen Verpackungsgütern geeignet.From the EP 0 867 379 A1 a perforated bag is known, with a perforation is made through all the layers of the bag. Although this ensures sufficient air permeability, the protection against moisture is no longer reliably given. Furthermore, such a bag is no longer suitable for receiving powdery packaging goods.

Aus der WO 98/57861 ist ein mehrlagiger Papiersack bekannt, der zur Aufnahme von pulverförmigem Verpackungsmaterial geeignet ist. Dabei weist der Papiersack an seinen Breitseiten jeweils Perforationen in Band- oder Streifenform zumindest in der Kunststoffzwischenlage auf. Um eine ausreichende Luftdufchlässigkeit zu gewährleisten müssen diese Perforationen bzw. Durchbrechungen einen entsprechend große Durchmesser aufweisen. Dabei wird die Festigkeit des Sacks jedoch herabgesetzt. Bei der Aufnahme von Gütern mit hohem Gewicht ist dies besonders nachteilig.From the WO 98/57861 a multi-ply paper bag is known, which is suitable for receiving powdered packaging material. In this case, the paper bag on each of its broad sides perforations in strip or strip shape at least in the plastic liner. In order to ensure adequate Luftdufdrlässigkeit these perforations or openings must have a correspondingly large diameter. However, the strength of the bag is reduced. This is particularly disadvantageous when accommodating high-weight goods.

Aufgabe der Erfindung war es daher, einen Papiersack bereitzustellen, der einen verbesserten Feuchtigkeitsschutz des Verpackungsgutes und gleichzeitig eine ausreichende Luftdurchlässigkeit bzw. Entlüftungsfähigkeit beim Befüllen des Sacks aufweist.The object of the invention is therefore to provide a paper bag, the improved moisture protection of the packaged goods and at the same time has sufficient air permeability or venting capability when filling the bag.

Gegenstand der Erfindung ist daher ein mehrlagiger Sack bestehend aus mindestens einer äußeren und mindestens einer inneren Papierlage und zwischen einer äußeren und einer inneren Papierlage situierten einer Kunststofflage, dadurch gekennzeichnet, dass der Papiersack an seiner Längsseite eine Überlappung der äußeren Papierbahn und eine partielle Überlappung der Kunststoffbahn vorgesehen ist und die äußere Papierbahn partiell mit sich selbst im Überlappungsbereich verklebt ist.The invention is therefore a multilayer bag consisting of at least one outer and at least one inner paper layer and located between an outer and an inner paper layer a plastic layer, characterized in that the paper bag on its longitudinal side an overlap of the outer paper web and a partial overlap of the plastic web is provided and the outer paper web is partially glued to itself in the overlapping area.

Vorzugsweise erfolgt die partielle Verklebung der außen liegenden Papierbahn auf zwei im Wesentlichen parallel zueinander liegenden Linien, wobei die Verklebungspunkte auf gleicher Höhe nebeneinander oder zueinander versetzt angeordnet sein können.
In einer weiteren Ausführungsform kann die partielle Verklebung in einer Linie erfolgen.Preferably, the partial bonding of the outer paper web takes place on two substantially mutually parallel lines, wherein the Verklebungspunkte can be arranged at the same height side by side or offset from one another.
In a further embodiment, the partial bonding can take place in a line.

Die Abstände zwischen den Verklebungspunkten bzw. die Abstände zwischen den partiellen Verklebungslinien sind abhängig von der Konsistenz und Gewicht des Füllguts.The distances between the gluing points or the distances between the partial gluing lines depend on the consistency and weight of the product.

Die innere Pappierbahn ist in ihrem Längsüberlappungsbereich durchgehend verbunden, beispielsweise durch Verkleben.The inner paperboard web is connected continuously in its longitudinal overlapping area, for example by gluing.

Die einzelnen Lagen des Sacks sind vorteilhafterweise zumindest partiell miteinander verbunden.
Die Kunststoffzwischenlage ist im fertigen Sack durch einfaches Überlappen festgelegt. Als Kunststoffzwischenlage kommen beispielsweise Kunststofffolien aus Polyolefinen, wie Polypropylen, Polyethylen, deren Copolymeren oder Mischungen in Frage.The individual layers of the bag are advantageously at least partially connected to each other.
The plastic liner is fixed in the finished bag by simply overlapping. Plastic liners of polyolefins such as polypropylene, polyethylene, their copolymers or mixtures are suitable as plastic liners.

Die Dicke der Kunststoffzwischenlage beträgt vorzugsweise etwa 10 bis 100 µm.
In einer weiteren Ausführungsform kann anstelle der Kunststoffzwischenlage, die äußere Papierlage eine Kunststoffbeschichtung aufweisen, wobei dabei ein beschichtungsfreier Randstreifen, in dem die partielle Verklebung vorgenommen wird, vorgesehen sein muss.The thickness of the plastic intermediate layer is preferably about 10 to 100 microns.
In a further embodiment, instead of the plastic intermediate layer, the outer paper layer may have a plastic coating, wherein a coating-free edge strip in which the partial bonding is carried out must be provided.

Ferner kann der Sack weitere Schichten, beispielsweise eine weitere Kunststoffschicht als zusätzliche Barriereschicht aufweisen.
Ferner können Außen- und/oder Innenlage aus Papier mehrlagig ausgeführt sein.
Der erfindungsgemäße Sack ist insbesondere für Produkte, die einen Feuchtigkeitsschutz benötigen, mit viel Luft und hoher Füllgeschwindigkeit beispielsweise über einen Füllstutzen in den Sack gefüllt werden.Furthermore, the bag can have further layers, for example a further plastic layer as an additional barrier layer.
Furthermore, outer and / or inner layer of paper can be made of several layers.
The bag according to the invention is particularly filled for products that require moisture protection, with plenty of air and high filling speed, for example via a filler in the bag.

Durch die unterbrochene Längsklebung der äußeren Papierhülle kann dabei die Luft noch während des Füllvorgangs vollständig entweichen.
Dadurch kann eine festere kompakte Packung der meist pulverförmigen Produkte erreicht werden.
Beispiele für Produkte, die in dem erfindungsgemäßen Sack eingefüllt und verpackt werden sind beispielsweise Zement, Mörtel, Bauhiffsmaterialien, chemische Produkte, Lebens- oder Futtermittel und dergleichen.Due to the interrupted longitudinal adhesion of the outer paper envelope while the air can escape completely during the filling process.
As a result, a firmer compact packing of mostly powdery products can be achieved.
Examples of products that are filled and packaged in the bag according to the invention are, for example, cement, mortar, construction materials, chemical products, food or feed and the like.

Der Sack kann Blockbodenbeutel, Kreuzbodenbeutel Seitenfaltenbeutel oder Pouch sein.
