Enhanced Flexible Material And Articles Formed Therefrom

A flexible film, and articles comprising the film, comprises interleaved pluralities of each of first bands and second bands disposed adjacent to the first bands. Both the first and second bands have a length and a width; the first bands comprise a first film basis weight and first and second regions. The first regions and second regions being comprised of the same material composition. The first regions undergo a substantially molecular-level deformation and the second regions initially undergo a substantially geometric deformation when the sheet material is subjected to an applied elongation along at least one axis. The second bands comprise a second film basis weight and a plurality of corrugations disposed along the length of the band. In this aspect the material may be described as having alternating bands of structural-elastic-like film and ring-rolled film.
