A monolayer monolithic waterproof-breathable film A with a thickness between 5 and 150 μm consists of at least 50% by weight of a highly breathable polymer. One of its faces exhibits an arithmetical mean roughness Ra of at least 0.1 μm. A process for manufacturing said film includes a stage (i) of formation, by coextrusion, of a multilayer film M comprising a bilayer B/A, wherein the layer A is as defined above. The layer B is a peelable layer with a thickness between and 100 μm and consisting of a dispersion of high density polyethylene (HDPE) in a continuous phase of atactic polypropylene. The amount of dispersed HDPE is such that layer B exhibits an arithmetical mean surface roughness Ra of at least 0.1 μm. Stage (ii) of the process includes separating the monolayer film A by peeling off the layer B in the multilayer film M.
