Monoaxial gereckte spleißfreie Packbänder aus PolyolefinenMonoaxially stretched, splice-free packaging tapes made from polyolefins

Die vorliegende Erfindung betrifft gereckte Packbänder aus isotaktischern Polypropylen, die durch Zusatz geeigneter Füllstoffe bestimmter Konzentration praktisch keine Spleißneigung bei ausreichender Rf.-ißfostigkGit gegenüber Artikeln aus unga füll ten Polyolefinen auf v/eisen.The present invention relates to stretched packaging tapes made of isotactic polypropylene, which by adding suitable fillers at a certain concentration practically no tendency to splice if there is sufficient Rf.-ißfostigkGit compared to articles from unga filled polyolefins on iron.

Packbänder v/orden bekanntlich z,B, benötigt, um Stückgüter aller Art, wie z.B. Platten, Steine, Blechtafeln, Ilolzgebiude, Kunststofftafeln etc, als rutschfeste Einholt transportieren zu können.As is well known, packing tapes are required, for example, to carry piece goods of all kinds, such as plates, stones, sheet metal, Ilolzgebiude, Transport plastic boards etc. as non-slip catches to be able to.

Hierbei v/ird das Packband um das Packgut gelegt und mit Hilfe eines Bandspanners bzw. einas Pückautoraaten straff angezogen. Anschließend wird das vor dorn Spannen über Anfang und Ende de;; Spannbandes geschobene sernannte Schloß mit einer Plombenzange verplombt. Hierdurch wird erreicht, daß das sich überlappende Band in dem Schloß fest verankert.Here the packing tape is placed around the packaged goods and with the help a tape tensioner or a Pückautoraaten tightened. Then the front of the mandrel is clamped over the beginning and end of the ;; Clamping strap pushed sernnamed lock with a Sealing pliers sealed. This ensures that the overlapping band firmly anchored in the lock.

Derartige Packbänder vurden binor auü i.jotaktischem, ungefülltem Polypropylen hergestellt und hatten jedoch den Nachteil, daß das Band beim Verplomben «ploißte und beim Auftreten höherer Zugkräfte aus dor Plombe gezogen wurde.Packaging tapes of this kind are made binary from i.jotactic, unfilled Made of polypropylene but had the disadvantage that the tape ploissed when it was sealed and when it stepped on higher tensile forces from the seal.

Ein weiterer Nachteil ist, daß die Verstreckung der bisher gefertigten Packbänder fast ausschließlich über eine beheizbare Walzenverstreckung erfolgte, da eine Verstreckung durch Zwischenschaltung eines Umluftkanals anstelle der Walzenverstrekkung eine höhere Spleißneigung der Packbänder zur Folge hatte.Another disadvantage is that the stretching of the hitherto The packaging tapes produced almost exclusively took place via heatable roller stretching, as stretching was carried out through Interposition of a circulating air duct instead of the roller stretching resulted in a higher tendency of the packaging tapes to splice.

Der Erfindung lag die Aufgabe zugrunde, die Spleißneigung auszuschließen und somit einen größeren Nutzeffekt für das Packband zu erreichen. Diese Aufgabe wurde erfindungsgemäß durch das in folgenden beschriebene Verfahren gelöst.The invention was based on the problem of the tendency to splice to be excluded and thus to achieve a greater efficiency for the packaging tape. This object was achieved according to the invention solved by the procedure described below.

Es wird zunächst dem in Pulver- oder Granulatfonn vorliegenden thermoplastischen Kunststoff, vorwiogend isotaktischem Polypropylen, ein geeigneter Füllstoff (z.B. auf Talkumbasis) in bestimmter Konzentration zugesetzt, Die erstellte Mischung wird dann im Extrusionsvorxahren mit anschließender monoaxialer Verstrickung zu iJdiidcrn verarbeitet.It will first be available in powder or granular form thermoplastic plastic, predominantly isotactic polypropylene, a suitable filler (e.g. based on talc) is added in a certain concentration, the mixture created is then in the extrusion process with subsequent monoaxial Entanglement processed into iJdiidcrn.

Gegenstand dor Erfindung sind dahsr monoaxial gereckte f nicht spleißende Packbänder aus isotaktischom Polypropylen, dadurch gekennzeichnet, daß das isotaktisoho Polypropylen mit einem mineralischen Füllstoff in Mengen von 1 bis 30 Gew.ία versetzt ist.Dor subject invention are monoaxially stretched dahsr f not spliced strips of Pack isotaktischom polypropylene, characterized in that the isotaktisoho polypropylene is mixed with a mineral filler in amounts of 1-30 Gew.ία.

Bisher \Airden gefüllte Polyolefine nie für derartige Zwecke mit großer Zugbeanspruchung eingebefczt. Das Vorurteil ist darin begründet, daß bekannterweise der Zu^aiü von Füllstoffen einen Abfall dor Festigkeit bewirkt, und -nan davon ausging, daß ein Packband, welches ja eine.ν Einwirkung großer Zugkräfte ausgesetzt ist, nicht dia erforderliche Festigko.it besitze:·.! könnte.Previously \ Airden never used filled polyolefins for such purposes with great tensile stress. The prejudice is based on the fact that, as is well known, the addition of fillers causes a decline in strength, and -nan assumed that that a packing tape, which is an effect of great tensile forces is exposed, not dia required Festigko.it own: ·.! could.

Die mineralischen Füllstoffe, die kein Kristallwasser enthalten sollen, werden bevorzugt in Mengen von 5 bis 20 Gew.% eingesetzt. Als geeignet sind insbesondere Talkum, Zinkoxyd, Bariumsulfat, AluminiumSilikate, Asbestmehl, Schiefermehl, Titandioxyd, Calciumcarbonat (Kreide) oder Glasfasern zu nennen.The mineral fillers, which should not contain any water of crystallization, are preferably used in amounts of 5 to 20 % by weight . Talc, zinc oxide, barium sulfate, aluminum silicates, asbestos flour, slate flour, titanium dioxide, calcium carbonate (chalk) or glass fibers are particularly suitable.

Überraschenderweise behindert der gleichmäßig im Thermoplasten verteilte Füllstoff die sonst bei ungefüllten Thermoplasten entstehende Einschnürung beim Recken derartig, daß keine nennenswerte Spleißneigung mehr zu beobachten ist.Surprisingly, the filler, which is evenly distributed in the thermoplastic, hinders what would otherwise be the case with unfilled thermoplastics resulting constriction during stretching in such a way that no appreciable tendency to splice can be observed any longer.

Die erfindungsgemäße Anwendung von gefülltem Polypropylen für Packbänder bietet gegenüber dem bisher üblichen Material Vorteile hinsichtlich der Anwendungsmöglichkeiten und des Herstellungsverfahrens.The use according to the invention of filled polypropylene for packaging tapes offers advantages over the material that has been customary up to now with regard to the possible applications and the manufacturing process.
