Description

Verwendung einer Kunststoffolie zum Verbinden von Blättern Es ist bekannt, Akten auf verschiedene Art und Weise zu heften. Eines der modernsten Verfahren zum Heften von Akten ist das »Papierverschweißen«, wobei auf dem Rücken der Akte statt eines Klebstoffs eine Kunststoffolie aufgelegt und in der Hitze geschmolzen wird. Der geschmolzene Kunststoff dringt oberflächlich zwischen die Papierfasern und verursacht so eine recht stabile Verbindung. Diese Art des Verklebens von Papierblättern wurde vielleicht etwas zu Unrecht als Papierschweißen bezeichnet. Man hatte nämlich festgestellt, daß die Folie bzw. der Kunststoff in Folienform die einzelnen Blätter doch nicht im gewünschten Maße zusammenhält.Using a plastic sheet to join sheets It is known to staple files in various ways. One of the most modern processes for stapling files is the "paper welding", whereby on the back of the files Instead of an adhesive, a plastic film is placed on top and melted in the heat will. The melted plastic penetrates the surface between the paper fibers and so creates a fairly stable connection. This way of gluing sheets of paper was perhaps wrongly called paper welding. Because you had found that the film or the plastic in film form the individual sheets but does not hold together to the extent desired.

Überraschenderweise wurde nun festgestellt, daß bei der Verwendung von gealterter Kunststoffolie, insbesondere einer Polyäthylenfolie, wesentlich besser Ergebnisse erzielt werden. Gegenstand der Erfindung ist also die Verwendung einer gealterten Kunststoffolie zum Verbinden von einzelnen und/ oder mehreren Blättern aus organischem Material, insbesondere Papierstoff oder sonstigem Faserstoffmaterial, unter Anwendung von Hitze. Surprisingly, it has now been found that when using Aged plastic film, especially a polyethylene film, is much better Results are achieved. The invention is therefore the use of a aged plastic film for joining individual and / or multiple sheets made of organic material, in particular paper or other fibrous material, using heat.

Als gealterter Kunststoff in Folienform kommt insbesondere solcher in Frage, der durch ionisierende Behandlung, wie UV- oder Infrarotbestrahlung oder durch eine sonstige Vorbehandlung unter Druck oder mit chemischen Mitteln, wie Ozon, gealtert worden ist. Es ist anzunehmen, daß durch die Alterung der Kunststoff aktiviert oder angegriffen wird unter Bildung von aktiven Zentren, die sich dann beim Schmelzen den reaktionsfähigen Gruppen des Blattmaterials, z. B. mit Hydroxylgruppen der Cellulose im Papier unter chemischer Bindung umsetzen und so eine echte Verschweißung bewirken. Von Polypropylen ist es z. B. bekannt, daß dieses bei der Bestrahlung durch energiereiche Strahlen aktive Zentren an der Oberfläche bildet, die weitere Angriffsflächen zur Pfropfpolymerisation bietet. The aged plastic in film form is particularly such in question, by ionizing treatment, such as UV or infrared radiation or by any other pre-treatment under pressure or with chemical agents such as ozone, has aged. It can be assumed that the plastic is activated by aging or is attacked with the formation of active centers, which are then melted the reactive groups of the sheet material, e.g. B. with hydroxyl groups of cellulose convert in the paper under chemical bonding and thus cause a real welding. From polypropylene it is z. B. known that this when irradiated by high-energy Radiation forms active centers on the surface, which further attack surfaces to Graft polymerization offers.

Erfindungsgemäß können als Kunststoffe für die Folien solche verwendet werden, deren Molekularstruktur die Bildung aktiver Zentren durch Alterung erlaubt. Dies sind beispielsweise Polyolefine wie Polypropylen und insbesondere Polyäthylen, Polyamide, Polyester usw. According to the invention, plastics can be used for the films whose molecular structure allows the formation of active centers through aging. These are, for example, polyolefins such as polypropylene and especially polyethylene, Polyamides, polyesters, etc.

Als zu verschweißendes Material kommt hauptsächlich Papier aller Art, z. B. Durchschlag-, Kunstdruck-, Saugpost und mittelfeines Papier, sowie der verschiedensten Zusammensetzung aus natürlichem, mit und ohne Zusatz an synthetischen Fasern, dann auch kaschiertes und mit Kunststoffen beschichtetes Papier (z.B. mit Polyurethanschaumstoff), dünne Gewebe, Gewirke und Vliese usw. in Frage. The main material to be welded is paper Kind, e.g. B. carbon copy, art print, suction mail and medium-fine paper, as well as the various composition of natural, with and without the addition of synthetic Fibers, then also laminated paper coated with plastics (e.g. with Polyurethane foam), thin woven fabrics, knitted fabrics and fleeces, etc.

Das zu verschweißende Material kann seinerseits ebenfalls aktiviert sein, falls es z. B. kunststoffhaltig ist. The material to be welded can in turn also be activated be if it z. B. contains plastic.
