The invention relates to a bag with lateral folds (1) with a weldable or sealable sheet lying upon at least one layer internal to the bag with two opposite main walls (2, 3) and two lateral fold walls (4, 5) lying therebetween, which join with extensions in a floor (9) and are connected there through at least one floor seam (10) in such a manner that the lateral fold walls (4, 5) are connected to each other on both sides of a fold corner (13, 14) flush with the adjacent main wall (2, 3) and such that, in addition, the main walls (2, 3) are connected to each other and are connected by a one-piece sheet running between main wall and floor designed for the improvement of the floor contour and the stability such that the floor (9) is delimited from each of the two main walls (2, 3) by a fold seam (11, 12).
