According to a method for manufacturing flexible bags: - a first strip (la) of flexible material is unwound as a continuous sheet in a longitudinal direction (F); - a hem (15) is formed on each edge of the first strip (la) and the hems (15) are glued over at least one length of a first or a second flap (11, 12) on one stitching face (150), - a fold is formed in the first strip (la) along a transverse folding line (13) to fold down the first flap (11) over the second flap (12) against an internal face (14) of the first strip (la), the fold bringing, for each edge, hem (15) against hem (15) so as to obtain the bonding of the hems (15), - the strip (la) is cut along a transverse section (111) to form the bag (1) at the end of the operations. Machine implementing the method and bag thus obtained.
