1. A flexible bag comprising at least one sheet of flexible sheet material assembled to form a semi-enclosed container having an opening defined by a periphery, the sheet of flexible material comprising a first band and a second band disposed adjacent to the first band, both the first and second bands having a length and a width,
wherein the first band comprises a first film basis weight,
wherein the first band comprises a strainable network comprising a first region and a plurality of discontinous second regions,
wherein at least a portion of the plurality of discontinuous second regions are separated by the first region,
wherein the first region undergoes a substantially molecular-level deformation and the plurality of second regions initially undergo a substantially geometric deformation when the sheet material is subjected to an applied elongation across the width of the first band,
wherein the second band comprises a second film basis weight that is lower than the first film basis weight and a plurality of substantially continuous corrugations, and
wherein each of the plurality of continuous corrugations extends fully along the length of the second band to span an entirety of the length of the second band.
