A forming, filling and sealing machine comprising:

• a first sealing mechanism for heat sealing a long sheet film carried downward with both side ends thereof overlapped with each other, said first sealing mechanism heat sealing said overlapped both side ends along the longitudinal direction of said film;
• a folding mechanism for forming two ridge portions in said film by inwardly folding the width direction center part of said long sheet film along the longitudinal direction of said film, the two ridge portions having tops, respectively;
• a second sealing mechanism for heat sealing at least the tops of the two ridge portions along the longitudinal direction of said film, the two ridge portions being formed in said film by means of said folding mechanism;
• an injection pipe perpendicularly provided for injecting filling material into the film heat sealed by said first sealing mechanism and said second sealing mechanism, said injection pipe being enclosed at the circumference thereof by said film;
• and
• a third sealing mechanism disposed below said injection pipe for heat sealing said film horizontally and cutting off the heat sealed portion.
