A bag includes front and back panels having joined first and second opposing side edges, and opposing top and bottom end edges. An end edge seal line adjacent one of the top and bottom end edges extends laterally from one side of the bag to the other for sealably closing the adjacent end edge of the bag. The opposite end edge of the bag is open for receiving contents therein and is subsequently closed to retain the contents within the bag. The improvement in the bag includes a folded in-tuck formed along one of the first and second side edges of the bag. The in-tuck cooperates with the front and back panels to define a side gusset adapted for allowing expansion of the bag when filled. The in-tuck is sealed along the end edge seal line to form a multi-ply reinforced end portion of the bag. A handle is formed with the reinforced end portion of the bag to allow convenient handling of the bag when filled.

[ I claim:] [1.]1. In a bag comprising front and back panels joined together to define a contents-receiving cavity, said panels having first and second opposing side edges, opposing top and bottom end edges, and an end edge seal line adjacent one of the top and bottom end edges and extending laterally from one side of the bag to the other for sealably closing the adjacent end edges of the bag, the opposite end edge of the bag being open for receiving contents therein and subsequently closed to retain the contents within the bag, the improvement comprising:(a) a folded in-tuck formed along one of the first and second side edges of said bag and cooperating with the front and back panels to define a side gusset adapted for allowing expansion of said bag when filled, said in-tuck being sealed along the end edge seal line to form a multi-ply reinforced end portion of said bag; and(b) a die-cut handle formed in the reinforced end portion of said bag and defining a handle slit communicating with the contents-receiving cavity of said bag, said handle allowing convenient handling of said bag when filled.
