A bag roll cutting device in which a bag roll comprising a series of wrapping bags wound up to form a roll is vertically accommodated in a container, the series of wrapping bags being constituted by an elongated cylindrical synthetic resin film flattened in the form of a band on which straight-line weldings are applied at certain intervals to form bottoms with score lines provided adjacent to the bottoms to allow the individual bags to be easily cut off. A cylindrical frictional cutter with an inside surface having a high degree of frictional resistance is secured to a top cover which is detachably fitted to the container in such a manner that the cylindrical frictional cutter is connected to a through hole of suitable size provided in the top cover. The front end portion of the bag roll is drawn out through the cylindrical frictional cutter from the end portion of the bag roll in the axial direction of the bag roll in the form of a string. A bag can be cut off the roll by pulling diagonally upwardly the front end of the bag roll with the aid of the tension and friction generated by the cylindrical frictional cutter.
