A process for manufacturing a, tetrahedral-shaped pouch (10) from a flexible strip of film material is such that a tube (13) is formed from a film strip (32) in a continuous manner involving the creation of a longitudinal sealing seam (12), and the tetrahedral shaped pouch (10) is formed from the tube(13) by means of alternatingly forming a first transverse sealing seam (14) running transverse to the longitudinal seam (12) and second transverse sealing seam (16) running essentially perpendicular to and a distance from the the first transverse seam (14), whereby the second transverse seams (16) are situated in the region of a tetrahedral corner (18) of the pouch (10), such that an essentially tube outlet part (20) for pouring that is closed at its free end (22) is formed projecting out from the pouch (10). The second transverse seams (16) are positioned such that the outlet parts (20, 20') projecting out from two neighbouring tetrahedral shaped pouches (10, 10') are delimited by regions (16a, 16a') of neighbouring transverse sealing seams (16, 16') that are arranged spaced apart from each other and their free ends (22) lie facing each other separated by a common part (16b) of the transverse sealing seams (16, 16').
