The ordered column packing comprises-in the form of packing layers containing flow channels (2)-foil-like material (1) with a fine structuring (10). The foil-like material is profiled with concave structure elements (3b; minus sign-) and convex structure elements (3a; plus sign+) in an alternating arrangement. An average distance a exists between centers of adjacent concave and convex structure elements respectively. This average distance a is substantially smaller than a distance between centerlines (20) of adjacent flow passages. The foil-like material has a second fine structuring which consists of regularly arranged apertures (5). An average distance b between centers of adjacent apertures is smaller than the average distance a, preferably smaller by at least 50%; and edges (51, 52) of the apertures have in each case a shaping comprising convex and concave locations (6a, 6b).
