    摘要: A stretchable outer cover for use with an absorbent article including an elastomeric film. The elastomeric film includes at least one skin layer that is less tacky than at least one core layer. The outer cover can include a nonwoven layer different structural combinations of spunbond fibers, meltblown fibers, and/or nanofibers. The combination of plastic and elastic components results in an outer cover that has favorable mechanical, physical, and aesthetic properties. The outer cover can be rendered either uniaxially or biaxially stretchable via a mechanical activation process.

    摘要: The present invention relates to a process of manufacturing a stretch composite, said method comprising: a) providing a first substrate in a machine direction, wherein said substrate has opposing first and second surfaces; b) providing a gravure printing roll having an exterior surface that comprises one or more cells wherein at least a portion of the surface is relatively cool; c) depositing a molten, non-adhesive, elastomeric composition onto the exterior surface of the gravure printing device which comprises a gravure printing roll, wherein less said composition is characterized as having a peel force of less than about 3 N/cm; d) causing said composition to be pushed into cells; and e) contacting said first surface of said substrate with said gravure printing roll and substantially completely transferring said elastomeric composition from said cells of said exterior surface on said gravure printing roll to said surface; wherein said process is substantially free of tackifier.
