Process for producing polyolefin microporous breathable film

Abstract

The present invention relates to a process for producing polyolefin / filler permeable films using machine directional or transverse orientation orientation using interconnected grooved cylinders (16, 26). Two-axis orientation - similarly to the production of permeable foils - can also be carried out by the same method. By heating the cylinders (16, 26), the permeability of the foil increases without increasing the interconnection depth of the interconnected cylinders. ŕ
