A one-step method of imparting breathability and elasticity to a film includes coextruding elastic fibbers within a matrix of a filled, semi-rigid film structure. Once the elastic fibers are within the film structure, the film can be stretched to impart breathability, while the elastic fibers provide elasticity. Furthermore, the elastic fibers can include an absorbent material. The resulting breathable, elastic film is particularly useful in diapers and other personal care products. |
