Abstract
The invention relates to a breathable multi-layer film with at least one layer containing a breathable resin, such as block copolymers with polyether blocks, and one layer containing a soft polymer (Tg<0° C.), such as a polyolefin. The film is selectively permeable to water vapor but not permeable to water. The film can be bonded to a woven or non-woven substrate to produce a breathable fabric.
