Verpackungsband aus Kunststoff und Verfahren zur Herstellung des Verpackungsbandes __Plastic packaging tape and method of manufacturing the packaging tape __

Die Erfindung betrifft ein Verpackungsband aus Kunststoff. The invention relates to a packaging tape made of plastic.

Es sind schon Kunststoffbänder der vorbezeichneten Gattung in verschiedenen Ausführungen bekannt. Zur Erhöhung der Festigkeit derartiger Kunststoffbänder ist auch schon vorgeschlagen worden, die Zugfestigkeit durch Verstreckung der Kunststoffbänder zu erhöhen. Dieser Verstreckung sind jedoch Grenzen gesetzt, denn es ist bekannt, daß die Makromoleküle der Thermoplaste beim VerStreckung3-vorgang im Innenbereich nicht über den ganzen Querschnitt voll erfaßbar sind, so daß der Innenkern, zur Mitte abnehmend, immer weniger der Verstreckung und Verkettung unterworfen ist, womit die Endprodukte nicht die vollen physikalisch möglichen Festigkeitswerte erreichen.Plastic tapes of the aforementioned type are already known in various designs. To increase the strength of such plastic strips has already been proposed, the tensile strength by stretching to increase the plastic straps. However, there are limits to this stretching, because it is known that the macromolecules of the thermoplastics during the stretching3 process in the interior are not fully detectable over the entire cross-section, so that the inner core, decreasing towards the center, is less and less subject to stretching and chaining, so that the end products are not the full physically possible strength values.

Der Erfindung liegt die Aufgabe zugrunde, die Zugfestigkeit der Verpackungsbänder insbesondere unter Verwendung des Verstreckungsverfahrens weiter zu erhöhen.The invention is based on the object of using the tensile strength of the packaging tapes in particular of the stretching process to increase further.

Diese Aufgabe ist erfindungsgemäß aaaurch gelöst worden, daß aas VerpackungsucOid aus mindestens zwei aufeinanderliegenden Schichten besteht., die vorzugsweise miteinander verbunden sind.This object has been achieved according to the invention aaaurch, that aas packaging ucOid consists of at least two superimposed Layers consists. Which are preferably connected to one another.

Bei dieser neuen Ausbildung hat das Verpackungsband zwei aufeinanderliegende Abschnitte mit jeweils im Verhältnis zur Kontaktoberfläche kleinem Querschnitt» Daraus ergibt sich der Vorteil, daß bei dem Verstrecken des Kunststoffbandes während der Herstellung mehr Jkakromoleküle verstreckt und miteinander verkettet werdens als es sonst bei großen Querschnitten der Fall ist» Die verstreckten verhältnismäßig dünnwandigen Wandabschnitte werden anschließend zur Anlage gebracht und damit zur gewünschten %uerschnittsdicke vereinigt. Dabei können beids Wandabschnitte miteinander durch Schweißen oder- Kleben verbunden werden, was den Vorteil ergibt, daß die Klebe- οdar Schwsißschicht eine zähe Einheit zwischen den WsJiclab schnitten oder Bändern bildet) wodui'ch. eine der Spleißneigung entgegengesetzte Wirkung erzielt wird* Diese Minderung der Spleißgefahr- kann noeh verbessert werae3^.;, wenn gleichseitig oder zusätzlich ia ä@n übrigen Oberflächen dia äußersten Makromoleküle big zum Schmelzpunkt aufgeheizt und daclui-oli initGinand©? auch ia Quer richtung verstärkt vcx-bundsn werden«In this new configuration, the strap has two superimposed portions each having a small relative to the contact surface cross-section "This has the advantage that s be stretched at the stretching of the plastic tape during manufacture more Jkakromoleküle and concatenated together as it otherwise with large cross-sections of the case, is »The stretched, relatively thin-walled wall sections are then brought to bear and thus combined to the desired% cross-section thickness. Both wall sections can be connected to one another by welding or gluing, which has the advantage that the adhesive or black layer forms a tough unit between the WsJiclab or strips) wodui'ch. an effect opposite to the tendency to splice is achieved * This reduction in the risk of splicing can still be improved. ; When big heated equilateral or additionally ia ä @ n other surfaces dia extreme macromolecules to the melting point and daclui-oli initGinand ©? vcx-bundsn will also become more vcx-bundsn across the board «

Nach einer Weiterbildung eier iürfindung ist das Verpackungsband so ausgebildet, daß die beiden vorzugsweise aufeinandergeschweißten Schichten aus einem gequetschten Rohr gebildet sind. Diese Ausbildung ist besonders für einAccording to a further development, the packaging tape is designed in such a way that the two layers, which are preferably welded to one another, consist of one pinched Tube are formed.

Nach einer anderen Weiterbildung der Erfindung ist das VerpackungsDand aus zwei aufeinandergelegten 3ändern zusammengesetzt. Beide Bänder können beispielsweise im Querschnitt zick-zack-förmig ausgebildet sein, wobei dann die Bänder formschlüssig aneinandergelegt werden. In diesercontinuous manufacturing process suitable. The two flattened layers of the pipe are side by side with each other connected, so that round splice-resistant edges result. According to another development of the invention, the packaging is dandy composed of two superimposed 3 bands. Both bands can, for example, in cross-section Be designed in a zigzag shape, the bands then being placed against one another in a form-fitting manner. In this

Ausbildung bietet das Verpackungsband zusätzlich den Vor- "Training, the packaging tape also offers the

teil einer weitgehenden Rutschsicherheit auf dem Verpakkungsgut sowie einer federnden Dickenstabilität, da bei Belastung oder Stoß die einzelnen dachförmigen Elemente nachgiebig sind, und somit kaum ein Durchstoßen befürchtet zu werden braucht. Auch die sonst gefährliche Quereinritzung wirkt sich Dei dieser Querschu^ttsformgebung kaum aus, weil in diesem Fall nur die ooeren Spitzen beschädigt wurden und die Kerbwirkung bei Zugbeanspruchung nur in einem Bruchteil zum Tragen kommt.

Nach einer zweiten Lösung der gestellten Aufgabe ist das Verpackungsband so ausgebildet, daß es axial verlaufende Hohlräume hat. Diese Hohlräume können im Querschnitt beispielsweise kreisförmig oder flach rechteckig sein. Auch diese Lösung bietet den Vorteil der Querschnittsverringerung und der Schaffung von Oberflächen im Inneren des Verpackungsbandes, wodurch die Anzahl der bei der Verstreckung erfaßten Makromoleküle vergrößert wird.According to a second solution to the problem posed, the packaging tape is designed so that it runs axially Has cavities. These cavities can be circular or flat, rectangular in cross section, for example. This solution also offers the advantage of reducing the cross section and creating surfaces inside the Packaging tape, reducing the number of times when stretching detected macromolecules is enlarged.

In Weiterbildung der Erfindung ist ein. Verfahren zum Herstellen des aus einem Kunststoffrohr hergestellten Verpackungsbandes entwickelt worden, welches sich dadurch auszeichnet, daß ein rohrförmig extrudierter, kalibrierter Bandrohling nach einer Abkühlung aufgeheizt, vorverstreckt, abgekühlt, nochmal aufgeheizt und hauptverstreckt wird, wobei der Bandrohling durch einen Heizdorn an der Innenfläche bis zum Schmelzpunkt erwärmt und durch Quetschwalzen zu einem flachen Band zusammengeschweißt wird, worauf das Band erneut aufgeheizt, nachverstreckt und thermostabilisiert und abgekühlt und durch hochenergetische Strahlen vernetzt und verfestigt wird.In a further development of the invention is a. Procedure for Manufacture of the packaging tape made from a plastic tube has been developed, which is thereby is characterized by the fact that a tube-shaped extruded, calibrated strip blank is heated, pre-stretched after cooling, is cooled, reheated and stretched the main, whereby the band blank is heated on the inner surface by a heating mandrel to the melting point and is formed into one by nip rollers flat tape is welded together, whereupon the tape is heated up again, post-stretched and thermally stabilized and cooled and is crosslinked and solidified by high-energy rays.

Dieser Herstellungsablauf kann vollkontinuierlich erfolgen, womit bei niedrigen Kosten hohe Produktionsleistungen erzielbar sind. Die beiden aneinanderliegenden Bandabschnitte können beispielsweise auch miteinander verklebt werden. Für die Strahlenbehandlung kommen vorzugsweise Alpha-, Beta- oder Gammastrahlen in Frage, wobei die Bestrahlung vor oder nach dem Kachverstrecken erfolgen kann.This production process can be carried out continuously, which means high production rates at low costs are achievable. The two adjacent tape sections can, for example, also be glued to one another will. Alpha, beta or gamma rays are preferably used for the radiation treatment, with the irradiation can be done before or after caching.

Nach einer anderen Lösung der gestellten Aufgaben, für die auch selbständiger Schutz beansprucht wird, wird zunächst ein breiteres Band hergestellt und wird dieses längs der Mittellinie gefaltet, worauf die beiden Hälften aneinandergelegt und miteinander verbunden werden. Dieser Fertigungsprozess erfordert besonders einfache Bearbeitungsvorrichtungen. After another solution to the set tasks, for which independent protection is also claimed, is first a wider band is made and this is folded along the center line, whereupon the two halves are placed against each other and be connected to each other. This manufacturing process requires particularly simple processing devices.
