[0007] To achieve the above purpose, the utility model provides a sealing film cutting tool for plane pasting film or container, which comprises a fixed die provided with a cutting hole and a movable die, the movable die can move between the position of extending into the cutting hole and the position of moving away from the cutting hole.

[0008] The inner peripheral wall of the fixed die at the cutting hole is provided with a first blade edge, and the outer peripheral wall of the movable die is provided with a second blade edge matched with the first blade edge.

[0009] The first blade edge and / or the second blade edge is concavely provided with a plurality of circumferentially distributed relief positions, the relief positions are gradually expanded in diameter from the head end to the tail end, and the head end of the relief position is a notch.

[0010] In actual design, the avoiding position is arranged on the fixed mold and / or the movable mold, so that the width of the connecting part formed by the avoiding position is smaller in actual processing, and the connection with the film roll is still stable, so that the connecting part can be stably broken under the action of hot pressing when the film roll and the label move to the next hot pressing station, the stability and efficiency of processing are ensured, and the instability caused by the large width of the connecting part is avoided.

[0011] The gradually expanding diameter of the avoiding position from the end to the surrounding part can be understood as both forming a connecting part and supporting, avoiding the problem that the uncut part is not broken when directly punching in the prior art, that is, the punching between the fixed mold and the movable mold is more uniform.
