A film bag has a pair of longitudinally extending film face panels having longitudinal edges and first and second folded film gussets having longitudinal edges welded at longitudinal seams to respective longitudinal edges of the face panels and formed with two spaced throughgoing cuts forming a handle loop. A separate film inner liner panel lies against an inner face of the first gusset, extends a full transverse width of the first gusset, and is fixed at the longitudinal welds of the first gusset to the front panels so that the liner prevents leakage from the bag through the cuts.

A reliable leakage resistant reinforced paper bag having reinforcement strips coupling the two handles and traversing the bag handle sides, spanning the bottom and coupled to the opposite bag side handle while increasing reliability and carrying capacity of the bag.
