Breathable multilayer films are provided. The multilayer films may include a monolithic core layer comprising a core-layer composition, which includes a core-layer highly breathable polymer and has a core-layer water absorption rate, and at least a first skin layer comprising a first-skin-layer composition, which includes a first-skin-layer highly breathable polymer and has a first-skin-layer water absorption rate. The core-layer water absorption rate may be at least about 10 times larger than first-skin-layer water absorption rate. Laminates including the multilayer films and at least one fibrous layer are also provided.

A disposable absorbent garment (10) comprising a topsheet (30), a back-sheet (32), an absorbent core (342) disposed between the topsheet and backsheet is disclosed. The absorbent core is formed from a folded laminate (342) comprising three layers, including an upper layer (342b), a lower layer (342c), a central fibrous layer (342a) including from about 50 percent to about 95 percent by weight super-absorbent polymer, and about 5 percent to about 50 percent by weight stabilization additives. The upper, and lower layers comprise tissue, airlaid fluff pulp or synthetic non-woven fibrous layers. The central fibrous layer is adhesively bonded to both the upper, and lower layers; all layers together assisting to maintain the dry, and wet integrity of the absorbent core. Folding of the thin absorbent laminate provides an absorbent core that can handle large doses of urine. The folded structure provides a central channel (360) that provides free volume for temporary liquid storage, and increases the surface area of laminate available for liquid absorption. The absorbent garment thus formed is very thin, lightweight, and economical.
