Absorbent article containing a porous polyolefin film

An absorbent article that contains an absorbent member positioned between a backsheet and a topsheet, wherein the absorbent article comprises a film formed from a thermoplastic composition that contains a continuous phase that includes a polyolefin matrix polymer and a nanoinclusion additive dispersed within the continuous phase in the form of discrete domains, wherein the nanoinclusion additive includes a functionalized polyolefin,

• wherein a porous network is defined in the composition that includes a plurality of nanopores having an average cross-sectional dimension of about 800 nanometers or less;
• wherein the nanoinclusion additive is present in the thermoplastic composition in an amount from about 0.05 wt. % to about 10 wt. % based on the weight of the continuous phase;
• wherein the composition further comprising a microinclusion additive dispersed within the continuous phase in the form of discrete domain and the microinclusion additive is a polymer that includes a styreneic copolymer, fluoropolymer, polyvinyl alcohol, polyvinyl acetate, or polyester;
• wherein the microinclusion additive is present in the thermoplastic composition in an amount of from about 1 wt. % to about 20 wt. %;
• and
• wherein the film has a hydrohead value of 50 centimeters or more, as determined in accordance with ATTCC 127-2008.
