Improvements in the formation of flexible containers, consisting of replacing the classic cross-section series of straight welds that is normally applied to a strip already closed superiorly and inferiorly, by another in which each of the welds is straight over almost its entire length, but that when approaching the limit of the strip it is subdivided forming an angle as "Y", the sides of whose angle are closed and with convexity towards the interior of the same, with which they are obtained in the filled and welded container, some full angles and perfectly straight.
