Abstract
A thermoplastic bag structure and a method for forming handle-containing bags in roll-form. The method includes the steps of forming a continuous collapsed tube; forming pairs of closely spaced seals transverse to the tube at bag length distances apart; forming a transverse line of weakness between each pair of seals; simultaneously or thereafter folding the marginal edges of the tube inwardly toward each other; forming and removing a cut-out region at one end of each sealed segment of the tube so that on removal of the cut-out region, the cut defines loop handles and a bag mouth region in each bag; again folding the marginal edges of the tube inwardly toward each other; and convolutely winding the structure to form severable bags on a roll.
