The method consists of filling a soft container ( 2 ) comprising two thin sheets sealedly joined together along a bounding perimeter by the following steps: providing an internally sterile container ( 2 ), inserting a nozzle ( 8 ) with a delivery mouth ( 9 ) through an aperture ( 5 ) formed in the container ( 2 ), conveying the fluid material into the container through said mouth ( 9 ), extracting the nozzle ( 8 ) from the container ( 2 ) after conveying the material; closing said aperture ( 5 ) by sealing the two sheets of the container ( 2 ). The filling machine comprises: a sealing box ( 3 ) comprising two complementary half-boxes ( 4 a , 4 b); clamping means for clamping together and unclamping said two half-boxes ( 4 a , 4 b) along respective sealing edges ( 21, 22, 23 ), to isolate its interior from the outside environment; aperture-forming means ( 26 a , 26 b , 26 c) located in said sealing box ( 3 ) to form an aperture ( 5 ) in that portion of the container ( 2 ) inserted in the box ( 3 ); filling means ( 8, 9 ) for filling the container ( 2 ) through the aperture ( 5 ); welding means ( 32 ) for sealing said aperture ( 5 ) on termination of filling.
