Abstract: Breathable multilayer films suitable for a wide variety of uses (e.g., protective apparel, surgical gowns, surgical drapes, aprons, roofing material, house wrap, etc.) are disclosed. The breathable multilayer film may include a monolithic core layer. The monolithic core layer may comprise at least one highly breathable polymer. The breathable multilayer film may also include at least one skin layer. The skin layer or layers may comprise at least one highly breathable polymer, a filler, and a non-breathable material. An exemplary structure of the breathable multilayer film provides a monolithic core layer, a first skin layer on one side of the monolithic core layer, and a second skin layer on the other side of the monolithic core layer. An exemplary construction of one or both of the skin layers includes one or more highly breathable polymers, a filler, and a non-breathable material. The filler, for example, may comprise calcium carbonate.
