Abstract
A bag has two face panels having upper and lower transversely extending end edges and longitudinally extending side edges between outer ends of the end edges, two side gussets each between a respective one of the side edges of one of the face panel and the respective side edge of the other face panel, and a base panel having a peripheral edge connected to the lower edges of the face panels and gussets. The panels and gussets form beveled or rounded corners at upper ends of the side edges. Respective corner welds at the corners each extend inward from the respective side edges while leaving the face panels unconnected and forming a filling opening between the corner welds.

-
two face panels having upper and lower transversely extending end edges and longitudinally extending side edges between outer ends of the end edges and lying flatly against each other in at least a central region; two side gussets each folded and lying between a respective one of the side edges of one of the face panel and the respective side edge of the other face panel, the panels and gussets forming beveled or rounded corners at upper ends of the side edges; a base panel folded inward between the face panels and having a peripheral edge connected to the lower edges of the face panels and gussets; and respective corner welds at the corners and each extending inward from the respective side edges while leaving the face panels unconnected and forming a filling opening between the corner welds, the corner welds fixing together the face panels and portions of the side gussets therebetween such that the side gussets cannot unfold at the corner welds.
