Abstract
The invention relates to a liquid-permeable primary dressing in the form of a supple thermoplastic section of material (1.4), comprising: a first smooth surface (4); a second surface (5) facing away from the smooth surface (4); and a plurality of three-dimensional perforations, whose walls extend from the first smooth surface (4) and end in an overhang with a free edge, thus making the second surface (5) rough to the touch. At least one of the free edges has an angled section that is approximately perpendicular to a perforation axis. In a preferred embodiment, the periphery (13) of the material section is smooth on both sides, i.e. on both the first and second surfaces (4; 5), the periphery (13) of the surface (5) that was at first rough being thermally smoothed.
