Abstract
An elastomeric breathable three-dimensional composite material and the process for producing the same are disclosed. A carrier material is supplied onto a top surface of continuous portions of an elastomeric film to form the composite material. A pressure differential is applied to a bottom surface of film for a period of time sufficient for three-dimensional apertured structures to be formed in the film.
