A method for treating a film by providing a structure including a substrate and an array of upstanding projections each of which includes multiple contact points. The structure is pressed against the surface of a polymeric film to cause deformation or rupture of the film. The film may then be pressed to partially reseal the perforations. The structure can be produced by electroplating a mould which includes an array of elements of dimensions corresponding to the projections of the desired structure.
L'invention concerne un procédé de traitement de pellicules qui met en oeuvre une structure comprenant un substrat et un réseau de projections verticales présentant chacune plusieurs points de contact. La structure est pressée contre la surface d'une pellicule polymère afin de provoquer la déformation ou la rupture de la pellicule. La pellicule peut ensuite être pressée pour reboucher partiellement les perforations. La structure peut être produites par électrodéposition d'un moule qui comprend un réseau d'éléments dont les dimensions correspondent aux projections de la structure désirée.
