PURPOSE:To obtain the present film, excellent in moisture and air permeability, water resistance and flexibility and suitable as rain apparels, disposable diapers, packaging materials, etc., by blending a polyolefinic resin with specific magnesium hydroxide, melt forming a film and drawing the resultant film. CONSTITUTION:The aimed film obtained by blending (A) 100pts.wt. polyolefinic resin with (B) 50-400pts.wt., preferably 60-200pts.wt. magnesium hydroxide, having 0.3-2.0mum, preferably 0.5-1.0mum average particle diameter and <=10m<2>/g, preferably 0.5-5.0m<2>/g specific surface area and subjected to surface treatment, then melt forming a film and drawing the resultant film in at least an uniaxial direction at >=1.1 times. |
