Title: (EN) Breathable elastic polymeric film laminates and absorption products
(ZH) 透气性弹性聚合物薄膜层压物和吸收制品
Abstract: front page image
(EN) An elastomeric breathable three-dimensional composite laminate (18) and the process for producing the same are disclosed. A carrier material (10) is supplied onto a top surface of continuous portions of an elastomeric film (12) to form the composite material. A pressure differential is applied to a bottom surface of the film for a period of time sufficient for three-dimensional apertured structures (36) to be formed in the film.
