ABSTRACT:
A carrier bag of heat-sealable plastic film has a front panel joined along side edges by weld lines to a rear panel. The top ends of the panels are joined by an inwardly foldable gusset which is integral in one piece with the panels. The gusset is joined at the ends to the weld lines such that when the bag is in expanded position, the gusset opens to form a top panel of the bag with inner triangular gussets at the ends thereof lying adjacent double-layer triangular film portions joined through the apexes thereof by the weld lines. A cut-out handle for the bag is formed in one of these double-layer triangular portions. The handle may be further reinforced by joining the two film layers of the double-layer portion by means of a V-shaped weld line having the apex on a side edge weld line and extending upwardly on each side of the cut-out handle.
