ABSTRACT:
A method for forming a thermoplastic film handled bag comprising: forming a continuous collapsed thermoplastic tube having heat seal lines across the width of said tube at bag length intervals, longitudinally folding opposite sides of the heat sealed tube equally towards each other until they meet at a common center line, folding the structure once again in the same direction along said center line and removing eight film layers in one of the corner regions defined by a heat seal line and the spine of the common center line fold, the film removal yielding a bag mouth opening and single loop handles at near the opposite ends of said bag mouth opening. Interconnected bags can be formed into a roll pack or individually severed bags can be unitized into a bag pack.
