1. A thermoplastic bag with one or more strainable networks formed by a structural elastic like process, the thermoplastic bag comprising:
first and second sidewalls of a thermoplastic film having a plurality of non-continuous raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film, wherein the plurality of non-continuous raised rib-like elements:
form one or more strainable networks; and
comprise raised rib-like elements arranged into repeating patterns comprising a first macro pattern and a second micro pattern, wherein second micro patterns are surrounded by first macro patterns;
a plurality of web areas positioned about the plurality of non-continuous raised rib-like elements; and
wherein the plurality of non-continuous raised rib-like elements and the plurality of web areas are sized and positioned such that, when subjected to an applied load, a stretch profile of the thermoplastic film has a complex shape.
