Abstract
A thermoplastic bag includes raised rib-like elements that allow the thermoplastic bag to expand. The thermoplastic bag further includes side seals having rib-like elements that allow the side seals to expand. Additionally, in one or more implementations, the thermoplastic bag includes one or more of a material formulation, a density of raised rib-like elements, a height of raised rib-like elements, or land areas that provide the raised rib-like elements with a reduced rebound ratio.
Claims20
A thermoplastic bag, comprising:
- first and second sidewalls comprising a thermoplastic material;
- the first and second sidewalls comprising a first side edge, an opposite second side edge, a bottom edge, and an opening along respective top edges;
- a closure mechanism that provides for selective closing of the top edges;
- a first side seal extending along the first side edge;
- a second side seal extending along the second side edge;
- and
- a plurality of raised rib-like elements formed in the first and second sidewalls;
- wherein the plurality of raised rib-like elements have a rebound ratio such that when the raised rib-like elements undergo an expansion of 15-30 percent under a strain of 3 to 6 pounds, the raised rib-like elements rebound less than 50 percent of the expansion.
