A process for manufacturing a tetrahedral-shaped pouch ( 100 from a flexible strip of film material is such that a tube ( 13 ) is formed from a strip ( 32 ) in a continuous manner involving the creation of a longitudinal sealing seam ( 12 ), and a tetrahedral shaped pouch ( 10 ) is formed from the tube ( 13 ) by means of alternating 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 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 as 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 neighboring tetrahedral shaped pouched ( 10, 10' ) are delimited by regions ( 16 a , 16 a') of neighboring 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 ( 16 b) of the transverse sealing seams ( 16, 16 ').
