The invention discloses a film having first and second segments alternating across the film's width direction. The second segments are more elastic than the first segments, and a force required to stretch the second segments is less than a force required to stretch the first segments. At least some of the first segments have apertures through their thicknesses, and a percentage of area of the first segments occupied by the apertures is greater than a percentage of area occupied by any apertures that may extend through the second segments. Laminates and absorbent articles including such films are also disclosed. A method of making the film is also described. 本发明公开了种膜，该膜具有在膜的宽度方向上交替的第区段和第二区段。该第二区段比第区段更有弹性，并且拉伸第二区段所需的力小于拉伸第区段所需的力。该第区段中的至少些区段具有穿过其厚度的孔，并且第区段的由孔占据的面积的百分比大于由可延伸穿过第二区段的任何孔占据的面积的百分比。还公开了包含此类膜的层合物和吸收制品。还描述了制备该膜的方法。
