Thermoplastic bags with duplicative seals

A thermoplastic trash bag, comprising:

• first and second sidewalls comprising a first side edge, a second side edge, and a bottom edge, the first and second sidewalls being un-joined along at least a portion of their respective top edges to define an opening;
• a first pair of side seals securing the first and second sidewalls together along the first side edge, wherein the first pair of side seals are spaced from the first side edge by a first distance;
• and
• a second pair of side seals securing the first and second sidewalls together along the second side edge, wherein the second pair of side seals are spaced from the second side edge by the first distance,
• wherein the thermoplastic trash bag lacks a heat seal at the first side edge and at the second side edge, and wherein portions of the first and second sidewalls between the first side edge and the first pair of side seals comprise SELFing or ring rolling deformations.
