IN A PROCESS FOR THE MANUFACTURE OF A STRIP MATERIAL (1) A PLASTICS LAYER (5, 6) IS FORMED AT LEAST ON ONE SIDE OF A SUPPORT (2) FROM A MIXTURE OF PLASTICS MATERIALS AND PARTICULATE SOLUBLE CORPUSCLES WHEREIN THE SOLUBLE CORPUSCLES ARE LEACHABLE BY A SOLVENT OF A TYPE AGAINST WHICH THE PLASTICS MATERIAL IS STABLE. THEREAFTER THE SOLUBLE CORPUSCLES ARE LEACHED OUT FROM THE PLASTICS LAYER (5, 6) WITH THE FORMATION OF THROUGHFLOW PASSAGES. ACCORDING TO THE INVENTION, A PLASTIC POWDER IS PREPARED AS THE PLASTICS MATERIAL, WHICH IS MIXED WITH THE SOLUBLE CORPUSCLES AND APPLIED ONTO THE SUPPORT (2). BY HEAT AND PRESSURE TREATMENT A PLASTICS LAYER (5, 6) INCLUDING THEREIN THE SOLUBLE PARTICLES, IS PRODUCED FROM THE MIXTURE OF PLASTICS POWDER AND SOLUBLE CORPUSCLES, PRIOR TO THE SOLUBLE CORPUSCLES BEING LEACHED AT LEAST IN PART OUT OF THE PLASTICS LAYER (5, 6).FIGURE 1
