A bag made from plastic film includes a handle and a gusset that is integral with the handle and with front and rear panels of the bag. Left and right side-welds unite the front and rear panels as well as the respective left and right ends of the handle. A process can create such structures from a single, seamless sheet of plastic. In the process, a handle opening is preferably provided in the handle, and a handle seal is provided below the handle opening. The handle may then be inserted between the front and rear portions, and the left and right side edges of the bag, the gusset and the handle may be fused together at respective left and right side-welds.
