PROBLEM TO BE SOLVED: To provide a bag sealing device capable of saving the bag sealing work and enhancing the capacity by shortening the operation time required to seal a mouth part of a bag. SOLUTION: A mouth part Fa of a bag F covered on flaps Ba, Ba, Bb and Bb of a box B is turned up by a pair of takeup plates 47 to constitute a bag takeup device 40, and pulled in a substantially flat state by a pair of bag pulling bars 51 to constitute a bag tensioning device 50. A flat portion of the bag F in a pulled state in a substantially flat state is lowered to the height close to a circumferential edge portion on the opening side of the box B, and the flaps Ba and Ba of the box B are bent in the longitudinal direction, and air inside the bag F is discharged and removed. The mouth part Fa of the bag F is wound and sealed by holding front and back edge portions on the flat side of the bag F by a pair of front and back winding bars 66 to constitute a bag winding device 60, and lowering it in the winding direction of the mouth part Fa of the bag F in a rotating direction.
