The utility model discloses a fastening structure for slitting a film mother roll, which comprises a body, and the body is sleeved on the surface of a film layer of the film mother roll and is positioned at the edge position of the film layer; after the body is arranged on the surface of the film layer in a sleeving mode, the body generates radial pressure on the film layer so as to press the film layer tightly. According to the utility model, the fastening structure is additionally arranged at the end part of the film layer of the film mother roll, and the fastening structure can generate radial pressure, so that the difficulty of axial movement among the layers is increased, the release of tension force is effectively prevented, the slitting quality problems of burrs, unevenness and the like of the slitting end surface are reduced and even eliminated, and the slitting quality is effectively improved. 本实用新型公开了一种薄膜母卷分切用紧固结构，包括本体，所述本体套设于所述薄膜母卷的膜层表面，且位于所述膜层的边缘位置处；所述本体套设于所述膜层表面后，所述本体对所述膜层产生径向的压力以压紧所述膜层。本实用新型通过在薄
