Abstract
In a method for making a permeable film, a physical force is applied to a film of a first material containing particles of a second material which is different from the first material. The second material has a higher susceptibility to the physical force than does the first material. Applying the physical force to the film affects the particles which in turn affect the first material of the film, thereby increasing permeability of the film.
