(EP2918629) A method for producing a breathable film based on polyvinyl chloride (PVC), including the following steps. Preparing a paste-like compound including a first fraction composed of PVC, a second fraction composed of a foreign material, and a third fraction composed of adjuvants and/or additives that that are mixed together to form the paste-like compound, applying the paste-like compound to a base, and drying and gelling the paste-like compound, which has been applied to the base, through the addition of heat, thus forming the film in which pores extending from the one surface of the film to the other are formed, which give the film breathability.
