Abstract
A breathable film having improved physical and barrier properties includes a stretched impact modified polyolefin matrix and a particulate filler. The impact modified polyolefin matrix includes at least one impact polypropylene copolymer, alone or in combination with other polymers. The film, and laminates including the film, provide excellent moisture breathability and excellent barrier to penetration by liquids. Laminates including the film may be used in diaper outercovers and other applications requiring breathability and resistance to penetration by liquids.
