PROBLEM TO BE SOLVED: To provide a moisture-permeable film which is soft, is excellent in moisture permeability and water resistance, and has a high expansibility and to provide an absorbent article prepd. by using the same. SOLUTION: A polyolefin resin compsn. prepd. by compounding 100 pts.wt. resin component comprising 20-100 pts.wt. crystalline low-density polyethylene having a density of 0.86-0.90 g/cm3, a melt index of 0.1-50 g/10 min, a ratio of wt. average mol.wt. no average mol.wt. of 3 or lower, and a content of 4-8Cα-olefin comonomers of 12 wt.% or higher and 80-0 pt.wt. polyethylene having a density of 0.915-0.950 g/cm3 with 50-400 pts.wt. inorg. filler is formed into a film and then stretched at least monoaxially to give the objective moisture-permeable film. An absorbent article is prepd. by using the moisture- permeable film as a lining material. |
