Description

Stapel aus Produkteinheiten wie beispielsweise aus einzelnen Rollen oder auch zu einem Turm übereinandergestapelten Rollen müssen beim Versand gegen die produktqualität-beeinträchtigende Einflüsse beim Transport oder bei der innerbetrieblichen Handhabung geschützt werden.Stacks of product units, such as individual rolls or rolls stacked on top of a tower, must be protected during shipping against the product quality-impairing influences during transport or during in-house handling.

Nach dem Stand der Technik kann gemäß der DE3120215 mit Schrumpffolie gearbeitet werden. Nachteilig ist dabei allerdings die Tatsache, dass der Schrumpf der Verpackungsfolie mit Hitze ausgelöst wird. Hat man ein temperatursensitives Gut wie beispielsweise Polypropylenvlies zu verpacken, kann diese Verpackungsart thermische Schädigungen am eigentlichen Produkt nach sich ziehen.According to the prior art can according to the DE3120215 be worked with shrink film. The disadvantage here, however, is the fact that the shrinkage of the packaging film is triggered by heat. If one has to pack a temperature-sensitive material such as polypropylene fleece, this type of packaging can cause thermal damage to the actual product.

Häufig werden daher sogenannte stretchverpackte Produktstapel hergestellt. Figur 2 zeigt einen schematischen Aufbau einer derartigen Verpackung:Frequently therefore so-called stretch-packed product stacks are produced. FIG. 2 shows a schematic structure of such a package:

Ein Produktstapel (4) wird aus einzelnen Rollen gebildet, die übereinander zu einem Turm gestapelt sind. Die Oberseite und die Unterseite des Produktstapels (4) werden mit sogenannten Ronden (1) und (1a) abgedeckt. Der Begriff Ronden steht dabei für Stanzlinge aus Karton oder Kunststoff, die einen Durchmesser aufweisen, der gleich dem des Produktstapels oder minimal geringer ist. Die Außenseite (5) des Produktstapels (4) wird während eines sogenannten Stretchprozesses mit einzelnen Lagen einer hochdehnfähigen Verpackungsfolie, der Stretchfolie (2a), umhüllt. Dabei wird darauf geachtet, dass die dabei gebildeten Folienlagen (2) auch einen Teil der Oberseite und der Unterseite des Produktstapels (4) ausgehend von der Kante am Übergang von der Außenseite (5) zur Ober- bzw. Unterseite überdeckt.A product stack (4) is formed from individual rolls which are stacked one above the other to form a tower. The top and bottom of the product stack (4) are covered with so-called blanks (1) and (1a). The term round blanks stands for diecuts made of cardboard or plastic, which have a diameter which is equal to that of the product stack or minimal. The outer side (5) of the product stack (4) is wrapped during a so-called stretch process with individual layers of a highly elastic packaging film, the stretch film (2a). Care is taken to ensure that the film layers (2) formed thereby also a part of Covering the top and the bottom of the product stack (4), starting from the edge at the transition from the outside (5) to the top or bottom.

Man bezeichnet diese Überdeckung üblicherweise als "Overstretch" (6). Je größer der Overstretch (6) ist, umso besser sind die Verpackungsronden (1) und (1 a) am Produktstapel (4) verankert.This coverage is usually referred to as "overstretching" (6). The greater the overstretch (6), the better the packaging blanks (1) and (1a) are anchored to the product stack (4).

Üblicherweise werden derartige Produktstapel (4) palettenfrei transportiert, sodass die Unterseite eines verpackten Produktstapels (4) durch die Bewegungsvorgänge beim Lagern, beim Verladen und ähnlichen Handhabungsvorgängen einer extremen mechanischen Belastung ausgesetzt ist. Häufig kommt es beispielsweise vor, dass ein verpackter Produktstapel (4) vom Gabelstapler nicht ausreichend hoch angehoben wird und die die Unterseite bildende Lage über den Boden geschleift wird. In der Folge wird durch diese Schubbelastung der Overstretch (6) mechanisch durch Reibung zerstört und die Übergangskante zwischen Unterseite und Außenseite freigelegt. Häufig fallen dabei auch die Ronden (1a) ab, sodass Verschmutzungen und Beschädigungen des eigentlich zu schützenden Produktes die Folge sind. Das Produkt wird dadurch unbrauchbar, da es entweder mechanisch beschädigt ist oder es verschmutzt wird und aufgrund dessen auch nicht mehr verwendbar ist.Usually, such product stacks (4) are transported pallet-free, so that the underside of a packaged product stack (4) is subjected to extreme mechanical stress as a result of the movement processes during storage, loading and similar handling operations. It often happens, for example, that a packaged product stack (4) is not lifted sufficiently high by the forklift and the layer forming the underside is dragged over the ground. As a result, the overstretch (6) is mechanically destroyed by friction and exposed the transition edge between the bottom and outside by this shear load. Frequently, the blanks (1a) also fall off, so that dirt and damage to the product actually to be protected are the result. The product is thus unusable because it is either mechanically damaged or it is dirty and therefore no longer usable.

Eine weitere, dem Stand der Technik zu entnehmende Arbeitsweise ist die Verwendung von Ronden als Bodenlage, welche über aus der Grundfläche sternförmig herausragende Laschen haben. Diese Laschen werden beim Stretchprozess an der Kante zwischen Außenseite und Unterseite des Produktstapels (4) umgefalzt und tragen dadurch zu einer weiteren Sicherung der Ronde auf der Unterseite bei. Nachteilig ist hier, dass die Umfalzung auch nur in einem bestimmten Umfang möglich ist. Vergrößert sich im beschriebenen Fall der Durchmesser einer Rolle, so kommt es dazu dass die Unterseite nicht mehr vollends von der Ronde bedeckt ist und zwischen den eingeschnitten Laschen das Produkt frei liegt. Verschmutzungen sind die Folge.A further mode of operation to be taken from the prior art is the use of round blanks as a base layer, which have tabs protruding in a star shape from the base surface. These tabs are folded during the stretch process at the edge between the outside and the bottom of the product stack (4), thereby contributing to further securing the blank on the bottom. The disadvantage here is that the Umfalzung is possible only to a certain extent. If, in the case described, the diameter of a roll increases, then the underside is no longer completely covered by the round blank and the product is exposed between the cut-in tabs. Dirt is the result.

Problematisch ist bei Verpackungen nach dem Stand der Technik auch der Umstand, dass derartig verpackte Produktstapel beim Aufnehmen vom Boden anschließenden Absetzen auf den Boden, bspw. beim Umlagern oder Versenden häufig Verschmutzungen an der Außenseite zwischen Stretchfolie und der Produktoberfläche aufweisen. Dies wird, wie in Figur 2 dargestellt, durch minimal zu großen Durchmesser der Ronden (1a) verursacht. Die Ronden stehen über die Außenkante des Produktstapels (4) heraus. Durch die Spannung der Stretchfolie (2a) beim Erzeugen des Overstretches (6) wird die Ronde (1a) zusammengedrückt und versucht dieser Stauchbelastung auszuweichen. Dabei kann es passieren, dass die Stretchfolie an der Kante der Ronde aufgeschnitten wird oder aber die Ronde wird verformt. Dies wiederum kann zur Faltenbildung innerhalb der Rondenfläche führen oder zu einer durch Verformung aus der Ebene heraus, dem sogenanntem "Balgen" führen.The problem with packaging according to the state of the art is also the circumstance that product packs packed in this way follow from the bottom when picked up Settling on the ground, for example. When repositioning or shipping often have pollution on the outside between stretch film and the product surface. This will, as in FIG. 2 represented by minimally large diameter of the blanks (1a) caused. The blanks protrude beyond the outer edge of the product stack (4). By the tension of the stretch film (2a) in generating the overstretch (6), the blank (1a) is compressed and tries to avoid this compression load. It can happen that the stretch film is cut at the edge of the round blank or the round blank is deformed. This in turn can lead to wrinkling within the Ronde surface or lead to a deformation out of the plane, the so-called "bellows".

Im Falle des Balgens wird beim Aufnehmen eines so verpackten Produktstapels (4) von der Ebene durch die dann einsetzende Balgbildung Luft über den Übergang des Overstretches (6) zur Ronde (1a) eingesaugt. Schmutzpartikel werden dabei zwangsweise mit eingesaugt. Beim Absetzen wird die zuvor eingesaugte Luft allerdings nicht wieder über diesen Weg ausgeblasen, sondern, da der Produktstapel (4) wieder auf dem Boden steht - entlang der Außenseite zwischen Stretchfolie (2) und Produktoberfläche verteilt. Auch hier wird das Produkt durch die Verschmutzungen teilweise oder komplett unbrauchbar.In the case of bellows, air is drawn in through the transition of the overstretch (6) to the blank (1a) when picking up a product stack (4) packed in this manner from the plane through the then beginning bellows formation. Dirt particles are forcibly sucked in with it. When settling the previously sucked air is not blown out again on this way, but, since the product stack (4) is back on the ground - distributed along the outside between stretch film (2) and product surface. Again, the product is partially or completely unusable due to the contamination.

Die Aufgabe der vorliegenden Erfindung war es, die genannten Nachteile des Standes der Technik zu vermeiden. Gelöst wird die Aufgabe durch die im Anspruch 1 genannten Merkmale. Sinnvolle Ausgestaltungen sind in den Unteransprüchen 2 bis 9 genannt.The object of the present invention was to avoid the mentioned disadvantages of the prior art. The problem is solved by the features mentioned in claim 1. Useful embodiments are mentioned in the subclaims 2 to 9.

Ein Verfahren zur Herstellung einer erfindungsgemäßen Verpackung ist in Anspruch 10 genannt.A method for producing a packaging according to the invention is mentioned in claim 10.

Der erfindungsgemäßen Verpackung liegt die Idee zugrunde, anstatt der üblichen, steifen Papp- oder Kunststoffronden als Bodenlage (3) eine mechanisch stabiles und trotzdem flexibles Material (3a) zu verwenden. Dabei wird der Durchmesser oder die Kantenlänge der Bodenlage (3) bewusst größer als der zu bedeckende Durchmesser oder die Kantenlänge der abzudeckenden Seite gewählt.The packaging according to the invention is based on the idea of using a mechanically stable and nevertheless flexible material (3a) as the base layer (3) instead of the usual rigid cardboard or plastic fronts. In this case, the diameter or the edge length of the bottom layer (3) is deliberately chosen to be larger than the diameter to be covered or the edge length of the side to be covered.

Durch die Verwendung einer erfindungsgemäßen Bodenlage (3) ist es des Weiteren möglich Durchmesserunterschiede auszugleichen und der Balgbildung vorzubeugen.By using a bottom layer (3) according to the invention, it is further possible to compensate for differences in diameter and to prevent the formation of bellows.

Erfindungsgemäß wird analog zum in die Ober- oder Unterseite hineinragenden Overstretch (6) der Stretchfolie (2a) auch mit der Bodenlage (3) ein Überstand (7) erzeugt, der in die Außenseite (5) des Produktstapels (4) hineinragt.According to the invention, a projection (7) is produced analogously to the overstretch (6) of the stretch film (2a) projecting into the upper or lower surface (3), which protrudes into the outer side (5) of the product stack (4).

Die Länge des in die Außenseite (4) hineinragenden Überstands (7) ist dabei in Abhängigkeit von der Flexibilität des für die Bodenlage (3) verwendeten Materials (3a) zu wählen.The length of the protrusion (7) projecting into the outside (4) is to be selected as a function of the flexibility of the material (3a) used for the bottom layer (3).

Figur 3 zeigt den zur Ermittlung der Flexibilität angewandten Test schematisch. FIG. 3 shows schematically the test used to determine flexibility.

Als Flexibilität im Sinne der vorliegenden Erfindung wird die Überhanglänge (12) bezeichnet, die sich an einem Messstreifen (15) des Materials (3a), wenn nach Testmethode "WSP 090.1.R4(12)" getestet, ergibt.Flexibility in the sense of the present invention refers to the overhang length (12) which results on a measuring strip (15) of the material (3a) when tested according to test method "WSP 090.1.R4 (12)".

Die vorstehend genannte Testmethode, wie auch die im späteren aufgezeigte "WSP 080.6.R4 (12)" und die "WSP 110.4.R4 (12)" sind erhältlich bei EDANA, Avenue Herrmann Debroux 46-B-1160, Brussels, Belgien, www.edana.org.The above test method, as well as "WSP 080.6.R4 (12)" and "WSP 110.4.R4 (12)" shown below, are available from EDANA, Avenue Herrmann Debroux 46-B-1160, Brussels, Belgium, www .edana.org.

Bei diesem Test mit einem Cantilever Biegetester, beispielsweise einem Testgerät Typ "Shirley Stiffness Tester" wird ein Streifen (15) des zu prüfenden Materials (3a) der Breite 25mm mit dem Messlineal (14) abgedeckt und mit dem Messlineal (14) zusammen über die Messkante des Testgeräts geschoben. Durch das Eigengewicht des Teststreifens (15) wird dieser durch die Schwerkraft nach unten gebogen. Wird ein Biegewinkel (13) von 41,5° erreicht, wird die Überhanglänge (12) am Messlineal (14) der Testeinrichtung in cm abgelesen und notiert.In this test with a cantilever bending tester, for example a tester type "Shirley Stiffness Tester", a strip (15) of the test material (3a) of width 25 mm is covered with the measuring ruler (14) and combined with the measuring ruler (14) over the Measuring edge of the test device pushed. Due to the weight of the test strip (15) this is bent by gravity down. If a bending angle (13) of 41.5 ° is reached, the overhang length (12) on the measuring ruler (14) of the test device is read in cm and noted.

Der Test wird mit Teststreifen (15) durchgeführt, die in Fertigungsrichtung, quer zur Fertigungsrichtung und in einem Winkel von 45° zur Fertigungsrichtung des die Bodenlage (3) bildenden Materials (3a) entnommen wurden.The test is carried out with test strips (15) which have been removed in the production direction, transversely to the direction of manufacture and at an angle of 45 ° to the direction of production of the material (3a) forming the bottom layer (3).

Sollte das zu testende Material (3a) unterschiedliche Oberflächen aufweisen, wie für die erfindungsgemäße Bodenlage (3) bevorzugt, muss der Teststreifen (15) so auf die Messoberfläche gelegt werden, dass die später die Außenseite der Bodenlage (3) bildende Oberfläche des Materials (3a) nach oben zeigt und mit dem Messlineal (14) abgedeckt wird.If the material to be tested (3a) has different surfaces, as preferred for the base layer (3) according to the invention, the test strip (15) must be placed on the measurement surface such that the surface of the material later forming the outside of the bottom layer (3) ( 3a) upwards and covered with the measuring ruler (14).

Dem Stand der Technik entsprechende Materialien, wie beispielsweise Wellpappronden der Firma Liebensteiner, Typ 1.30e bs weiß, sind mit den methodengemäß ausgerüsteten Prüfeinrichtungen nicht messbar, da sich mit diesen Prüfeinrichtungen Überhanglängen bis maximal 30cm ermitteln lassen , sich an den untersuchten Mustern bei diesem Überhang noch keinerlei Durchbiegung einstellte. Tatsächlich liegen derartige, dem Stand der Technik entsprechende Materialien bei größer 80cm.The prior art materials, such as corrugated paper probes from Liebensteiner, type 1.30e bs white, are not measurable with the test equipment equipped according to the method, since overhang lengths of up to 30 cm can be determined with these test equipment, nor on the examined samples in this overhang no deflection was set. In fact, such prior art materials are greater than 80cm.

Erfindungsgemäß für die Bodenlage (3) einsetzbare flexible Materialien (3a) weisen daher geringe Überhanglängen auf. Erfindungsgemäße Materialien (3a) haben gemäß der vorstehend beschriebenen Prüfmethode Flexibilitäten im Bereich von 5 bis 30 cm, bevorzugt im Bereich von 8 bis 20cm. Höhere Flexibilitäten geben Probleme bei Anwendung der nachfolgend beschriebenen Verpackungsmethoden und bringen auch keine Weiteren Vorteile bezüglich der mechanischen Beständigkeit.Flexible materials (3a) which can be used according to the invention for the bottom layer (3) therefore have low overhang lengths. Inventive materials (3a) according to the test method described above have flexibilities in the range of 5 to 30 cm, preferably in the range of 8 to 20cm. Higher flexibilities present problems with the packaging methods described below, and also provide no further advantages in terms of mechanical resistance.

Bei geringeren Flexibilitäten ist, wenn man im unteren Bereich des erfindungsgemäßen Überstands (7) arbeitet, die Gefahr, dass die Bodenlage (3) herausgerissen wird, deutlich erhöht.With lower flexibilities, if one works in the lower region of the supernatant (7) according to the invention, the risk of the bottom layer (3) being torn out is markedly increased.

Die Flexibilität des die Bodenlage (3) bildenden Materials (3a) ist bei der Erzeugung eines erfindungsgemäß verpackten Produktstapels (4) von entscheidender Bedeutung.The flexibility of the material (3a) forming the bottom layer (3) is of crucial importance in the production of a product stack (4) packed according to the invention.

Wie der Figur 4, einem prinzipiellen Weg wie man eine erfindungsgemäße Verpackung herstellen kann, zu entnehmen ist, wird die spätere Bodenlage (3) in der Auflegestation (9) zunächst zentriert auf die Oberseite des Produktstapels (4) gelegt. Durch die Flexibilität des die Bodenlage (3) bildenden Materials (3a) faltet sich der über die Kanten des Produktstapels hinausragende Anteil der Bodenlage (3) an der Kante selbstständig und bildet den Überstand (7). Dabei sind keine weiteren Hilfsmittel wie bspw. Falteinrichtungen oder Luftgebläse notwendig, das Falten geschieht rein durch die auf den Überstand wirkende Schwerkraft.Again FIG. 4 , A principle way how to produce a packaging according to the invention, it can be seen, the subsequent bottom layer (3) in the laying station (9) is first placed centered on the top of the product stack (4). Due to the flexibility of the material (3a) forming the bottom layer (3) folds the portion of the bottom layer (3) projecting beyond the edges of the product stack is independent of the edge and forms the projection (7). There are no other aids such as. Folding or air blower necessary, the folding is done purely by acting on the supernatant gravity.

Die Länge des Überstands (7) muss dabei mindestens das Anderthalbfache der in cm ermittelten Flexibilität des die Bodenlage 3 bildenden Materials (3a) betragen. Liegt der Überstand (7) geringer, kommt es bei der nachfolgenden Stretchung zu Problemen mit der Fixierung der Bodenlage (3). Auch ist dann die Gefahr gegeben, dass die erfindungsgemäße Bodenlage (3) aufgrund mechanischer Schubbelastungen bei der Handhabung herausgezogen wird.The length of the projection (7) must be at least one and a half times the determined in cm flexibility of the bottom layer 3 forming material (3a). If the supernatant (7) is lower, there will be problems with the fixation of the bottom layer (3) during the subsequent stretching. Also, then there is the danger that the floor layer (3) according to the invention is pulled out due to mechanical thrust loads during handling.

Erfindungsgemäß bevorzugt werden Längen des Überstands (7) im Bereich des doppelten bis zum fünffachen Wert der Flexibilität des die Bodenlage (3) bildenden Materials (3a).According to the invention, lengths of the projection (7) are preferably in the range of twice to five times the value of the flexibility of the material (3a) forming the base layer (3).

Anschließend wird der so erzeugte Produktstapel einer handelsüblichen Stretcheinrichtung (10) zugeführt. Der Produktstapel wird mit einzelnen Lagen der Stretchfolie (2a) umhüllt. Dazu kann entweder der Produktstapel (4) selbst in Rotation versetzt werden oder aber die Spendeeinheit (10) für die Stretchfolie (2a) rotiert um den Produktstapel (4). Während der Rotation bewegt sich die Spendeeinheit mehrmals auf und ab. Dabei werden einzelne Lagen aus Stretchfolie (2a) spiralförmig übereinander abgelegt und bilden nach Abschluss dieses Vorgangs in ihrer Gesamtheit die Folienlagen (2).Subsequently, the product stack thus produced is fed to a commercially available stretch device (10). The product stack is covered with individual layers of the stretch film (2a). For this purpose, either the product stack (4) itself can be set in rotation or else the dispensing unit (10) for the stretch film (2a) rotates about the product stack (4). During rotation, the dispensing unit moves up and down several times. In this case, individual layers of stretch film (2a) are superimposed spirally one above the other and form after completion of this process in their entirety the film layers (2).

Die Anlage ist dabei so eingestellt, dass sich der Overstretch (6) sowohl am oberen Ende als auch am unteren Ende des Produktstapels (4) ergibt.The system is set so that the overstretch (6) results both at the upper end and at the lower end of the product stack (4).

Abschließend wird der so verpackte Produktstapel (4) in einer Drehstation (11) um 180° gedreht, sodass die die Bodenlage (3) nun auf der dem Boden zugewandten Seite des Produktstapels(4) zu liegen kommt.Finally, the packaged product stack (4) is rotated in a rotating station (11) by 180 °, so that the bottom layer (3) now comes to rest on the side facing the bottom of the product stack (4).

Erfindungsgemäße für die Bodenlage (3) einsetzbare Materialien (3a) haben wie bereits vorstehend aufgezeigt, eine Flexibilität im Bereich von 5 bis 25cm. Die Flexibilität muss in dem Material (3a) homogen vorhanden sein. Dies bedeutet, dass das die Bodenlage (3) bildende Material (3a) in Fertigungsrichtung, quer zur Fertigungsrichtung und in einem Winkel von 45° zur Fertigungsrichtung annähernd gleiche Überhanglängen (12) aufweist. Diese Eigenschaft ist wichtig um ein gleichmäßiges Falten um die Kanten speziell bei runden Produktstapeln (4) zu erzielen.Inventive materials for the bottom layer (3) usable materials (3a) have, as already shown above, a flexibility in the range of 5 to 25cm. The Flexibility must be present homogeneously in the material (3a). This means that the material (3a) forming the bottom layer (3) has approximately the same overhang lengths (12) in the production direction, transversely to the production direction and at an angle of 45 ° to the production direction. This property is important to achieve a uniform fold around the edges, especially with round product stacks (4).

Geeignet für die Bodenlage (3) sind alle Arten von flexiblen, flächigen, wasserdichten und mechanisch belastbaren Materialien (3a) mit den vorerwähnten Eigenschaften.Suitable for the bottom layer (3) are all types of flexible, flat, waterproof and mechanically strong materials (3a) with the aforementioned properties.

Wasserdicht im Sinne der vorliegenden Erfindung bedeutet, das das Material (3a) einen Wert für die Wassersäule (ermittelt nach "WSP 080.6.R4 (12)") von größer 1000mm Wassersäule aufweist.Waterproof in the sense of the present invention means that the material (3a) has a value for the water column (determined according to "WSP 080.6.R4 (12)") of greater than 1000 mm water column.

Mechanische belastbar im Sinne der vorliegenden Erfindung bedeutet, das das Material (3a) entlang oder quer zur Fertigungsrichtung des Materials (3a) eine Reißkraft von größer 200N/25mm (ermittelt nach "WSP 110.4.R4 (12)", Option A) aufweist.Mechanical loadable in the sense of the present invention means that the material (3a) along or transversely to the production direction of the material (3a) has a tensile strength of greater than 200N / 25mm (determined according to "WSP 110.4.R4 (12)", option A).

Erfindungsgemäß bevorzugt werden mehrlagige Laminate von Folien mit Geweben, wobei Laminate aus Folien mit Bändchengeweben am meisten bevorzugt werden.Multi-layer laminates of films with fabrics are preferred in the present invention, with laminates of films with ribbon fabrics being most preferred.

Zweilagige Laminate aus einem Bändchengewebe auf der einen Seite und einer Folienlage auf der anderen Seite bringen für die erfindungsgemäße Verpackung weitere Vorteile.Two-layer laminates of a ribbon fabric on one side and a film layer on the other side bring further advantages for the packaging according to the invention.

Derartige Aufbauten, wie beispielsweise unter der Produktbezeichnung BE113 von Lenzing Plastics, Lenzing, Österreich erhältlich, bestehen aus einer LD-Polyethylen-Folie mit 35 g/m2, welche mittels direkt auf ein 78g/m2 Bändchengewebe aus HD-Polyethylen extrudiert und dadurch verbunden wurde. Dieses Material weist Flexibilitäten in Fertigungsrichtung ca.8,5 cm, quer zur Fertigungsrichtung von ca.8,4cm und in einem Winkel von 45° zur Fertigungsrichtung von ca. 8,2cm auf. Dabei wurde, gemäß dem Testaufbau aus Figur 3 die Seite mit dem Bändchengewebe in Richtung des Messlineals (14) gelegt. Eine derartiges Aufbau hat des Weiteren eine mechanische Beständigkeit von 255N/25mm in Fertigungsrichtung und von 330N/25mm quer zur Fertigungsrichtung. Die Wasserdichtheit liegt bei größer 3000mm/WS.Such structures, such as under the product BE113 of Lenzing Plastics, Lenzing, Austria available, consist of a low density polyethylene film having 35 g / m 2, which is extruded by means of directly to a 78g / m 2 woven fabric of high density polyethylene and thereby was connected. This material has flexibilities in the production direction about 8.5 cm, transverse to the production direction of about 8.4 cm and at an angle of 45 ° to the production direction of about 8.2 cm. It was, according to the test setup FIG. 3 put the side with the ribbon fabric in the direction of the measuring ruler (14). Such a construction Furthermore has a mechanical resistance of 255N / 25mm in the direction of production and 330N / 25mm across the direction of production. The watertightness is greater than 3000mm / WS.

Werden derartige Laminate als Materialien (3a) für die Bodenlage (3) verwendet, so wird das Material (3a) auf dem Produktstapel (4) so platziert, dass die Folienseite zum Produktstapel (4) hin zeigt und die Seite mit dem Bändchengewebe nach außen. Erfindungsgemäß werden die Abmessungen der Bodenlage (3) so bemessen, dass sich dabei ein Überstand (7) der Bodenlage (3) in Höhe von 30 cm bildet, was dem 3,6-fachen der Flexibilität des die Bodenlage (3) bildenden Materials (3a) entspricht.When such laminates are used as the bottom sheet material (3a), the material (3a) is placed on the product stack (4) so that the film side faces the product stack (4) and the ribbon fabric side faces out , According to the invention, the dimensions of the bottom layer (3) are dimensioned such that a projection (7) of the bottom layer (3) is formed at a height of 30 cm, which is 3.6 times the flexibility of the material forming the bottom layer (3). 3a) corresponds.

Das Bändchengewebe erhöht aufgrund der Oberflächenstruktur die Haftung an Oberflächen wie beispielsweise auf Böden, was beispielsweise wichtig für den Transport im LKW ist, da die Produktstapel (4) weniger zum Verschieben neigen. Weiterhin wird auch die Gefahr, dass die Bodenlage (3) herausgerissen wird, aufgrund der erhöhten Reibung. deutlich verringert.Due to the surface structure, the ribbon fabric increases the adhesion to surfaces such as floors, which is important for transport in the truck, for example, because the product stacks (4) are less prone to shifting. Furthermore, the risk that the bottom layer (3) is torn out, due to the increased friction. significantly reduced.

Des Weiteren bilden die Schuss- und Kettfäden des Bändchengewebes im Bereich des Overstretches (6) und des Überstands(7) eine mechanische Barriere für Schmutzpartikel. Sollte es zum Aufbalgen des Produktstapels (4) kommen, werden die Schmutzpartikel in den Strukturen des Bändchengewebes zurückgehalten.Furthermore, the weft and warp threads of the ribbon fabric in the region of the overstretch (6) and the supernatant (7) form a mechanical barrier for dirt particles. Should it come to the lifting of the product stack (4), the dirt particles are retained in the structures of the ribbon fabric.
