PROBLEM TO BE SOLVED: To provide a bag packaging machine which can prevent contact between a horn and an anvil used in an ultrasonic seal.SOLUTION: A bag packaging machine 1 includes a lateral seal mechanism 17, a horn supporting body 71, and a pressure part 72. The lateral seal mechanism 17 holds a cylindrical film Fc with a first horn 51a and a first anvil 51b. The first horn 51a has a plurality of resonance bodies 513 arranged in a width direction. The horn supporting body 71 has a first supporting member 73, a second supporting member 74, and a connection member 75. The plurality of resonance bodies 513 are fixed to the first supporting member 73. Both ends of the second supporting member 74 are pressurized by the pressure part 72. The connection member 75 connects a first central part 73a being a central part of the first supporting member 73 and a second central part 74a being a central part of the second supporting member 74. The first central part 73a is positioned between a pair of end fixing parts 73b to which the resonance bodies 513 on both ends in the width direction are fixed. |
