Abstract

Um in einer Folie (1) aus thermoplastischem Kunststoff Perforationslöcher (2) herzustellen, werden auf der Folie (1) überall dort, wo solche Perforationslöcher (2) herzustellen sind, durch eine Vorbehandlung, beispielsweise durch Auftragen von Pigmenten, Bereiche (4, 8, 10) erzeugt, in denen die Absorption bezüglich zugeführter Energie im Vergleich zu den anderen, nicht vorbehandelten Bereichen der Folie (1) erhöht ist. So wird erreicht, dass die Folie (1) beim Zuführen von Energie, wegen der in den vorbehandelten Bereichen (4, 8, 10) verstärkten Absorption für die zugeführte Energie so stark erwärmt wird, dass sie unter Ausbilden der gewünschten Perforationslöcher (2) aufschmilzt. So entstehen in der Folie (1) Perforationslöcher (2), die rissfrei sind.

In order to produce perforation holes (2) in a film (1) made of thermoplastic material, areas (4, 8) are produced on the film (1) wherever such perforation holes (2) are to be produced by pretreatment, for example by application of pigments , 10) in which the absorption with respect to supplied energy is increased compared to the other, non-pretreated areas of the film (1). Thus, it is achieved that the film (1) when supplying energy, because of the in the pretreated areas (4, 8, 10) increased absorption for the energy supplied is heated so much that it melts to form the desired perforation holes (2) , Thus arise in the film (1) Perforationslöcher (2), which are free of cracks.
