Patent ID: 7932196

Claim:
A breathable laminate having a moisture vapor transmission rate of at least about 300 g/m 2 /24 hours comprising a nonwoven support layer bonded to an oriented film comprising a letdown resin phase wherein said letdown resin comprises a first ethylene copolymer having a density between 0.900 and 0.915 g/cc and a melt index of no greater than 6 g/10 minutes and a carrier resin phase comprising a filler and a different ethylene polymer or copolymer having a density at least about 0.003 g/cc greater than the density of said letdown resin, wherein substantially all of said filler in said oriented film is contained only within discrete regions of said carrier resin phase and thereby separated from contact with said letdown phase, and wherein each of the discrete regions of the carrier resin phase is completely intermixed with and surrounded by the letdown resin phase.
