摘要： Multilayer microporous films comprise first and second microporous film layers. The first film layer has a first maximum pore size and the second film layer has a second maximum pore size different from the first maximum pore size. In a more specific embodiment, the multilayer microporous films comprise coextruded first, second and third microporous film layers. One of the first, second and third film layers has a maximum pore size smaller than the respective maximum pore sizes of the remaining layers of the multilayer film or larger than the respective maximum pore sizes of the remaining layers of the multilayer film, and the one layer does not have an unconstrained surface in the multilayer film. Methods for producing multilayer microporous films provide a first film layer having a maximum pore size upon stretching which is different from that of a second film layer upon stretching.

摘要： Embodiments of a breathable multilayer microporous film comprise a first outer film layer, a second inner film layer, and a third outer film layer, wherein each film layer comprises at least one pore-forming filler and one thermoplastic polymer. Each film layer is rendered microporous and breathable by stretching each film layer having the pore-forming filler therein, wherein the first and third outer film layers have first and third maximum pore sizes, respectively, and the second inner film layer has a second maximum pore size different than the respective maximum pore sizes of the first and third outer film layers of the multilayer film. The multilayer microporous film passes ASTM F 1671-03 test.

摘要： A method of making a laminate sheet having a film layer and a fabric layer. The method includes the step of bonding a film layer to a fabric layer in order to form a laminate sheet such that the laminate sheet includes at least one high-bond region whereat the strength of the bond between the film and fabric layers is greater than other regions of the laminate sheet. The method further includes the step of stretching the laminate sheet such that the high-bond regions are either not stretched or are only partially stretched. A method of making a diaper backsheet, as well as a stretched laminate of a polymeric film and a fabric web, is also provided.
