Beschreibung
Zusammenfassung:	A film having first and second segments arranged along the film's width direction. The second segments are more elastic than the first segments. The first segments can include a polymer and a diluent that is miscible with the polymer at a temperature above a melting temperature of the polymer but that phase separates from the polymer at a temperature below a crystallization temperature of the polymer, or the first segments can include at least one of a beta-nucleating agent or thermally induced phase separation caused by a diluent. Laminates and absorbent articles including such films are also disclosed. A method of making the film is also described.
