摘要： Absorbent articles having a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core disposed between said topsheet and said backsheet are disclosed. The backsheet has a physical variation along at least one axis, wherein said physical variation defines a first backsheet zone and a second backsheet zone, and at least one elastomeric element having at least one primary direction of stretch, said elastomeric element at least partially overlapping and joined to first and/or second backsheet zone, wherein a relaxed pathlength of said elastomeric element in the primary direction of stretch is less than a total pathlength of said backsheet in the region of overlap. The physical variation is a measurable difference as measured by a physical property selected from the group consisting of basis weight, thickness and density.

摘要： An absorbent article comprises a lateral axis defining a front portion and a back portion in the absorbent article, a topsheet, and a backsheet. The absorbent article further comprises an absorbent core positioned at least partially intermediate the topsheet and the backsheet. The backsheet comprises a first backsheet zone positioned at least partially in the front portion, and a second backsheet zone positioned in the back portion. The first and second backsheet zones differ from each other in at least one physical property. The physical property is basis weight, thickness, density, and/or tensile modulus. The second backsheet zone overlaps a portion of the absorbent core in the back portion. The second backsheet zone is not bonded to the absorbent core in the area of overlap.

摘要： A breathable, substantially liquid impermeable film and laminate are provided for use in a wide variety of personal care garments and protective garments. The film, and laminate containing the film, are extendible in a cross-direction to a stretched width which is at least 25% greater than an original, unstretched width. The film and laminate have a first water vapor transmission rate of at least about 500 grams/m2-24 hours coinciding with the unstretched width. The film and laminate have a much higher second water vapor transmission rate which is at least about 225% of the first water vapor transmission rate, and not less than about 4000 grams/m2-24 hours, coinciding with a stretched width that is only 25% greater than the stretched width.

摘要： A breathable multilayer film including a breathable core layer and one or two skin layers is prepared by providing a core layer mixture of a thermoplastic polymer and a particulate filler, providing a skin layer mixture of at least two incompatible polymers, coextruding the core and skin layer mixtures to form a multilayer film, and stretching the multilayer film to cause void formation in the core layer and crack formation in the one or two skin layers. By forming cracks in the skin layers during stretching, the skin layers can perform dual functions of alleviating die build-up of filler from the core layer during coextrusion, and bonding the film to a substrate subsequent to coextrusion, without unduly hindering the moisture vapor transmission rate of the film or laminate product. The breathable film, and laminates including the film, are useful in a wide variety of personal care absorbent articles, medical garments, and other products.
