1. Add a balance pressure spoke on the waste discharge spoke, and properly balance the diameter of the waste discharge edge with external force.
2. Add proper lining paper at the winding position with less waste edges to balance the tension of waste edges.
3. Before die-cutting, the pre-stripping process is used to appropriately reduce the demoulding force of the material. The greater the waste discharge tension of materials, it is not conducive to the smooth discharge of waste, especially the special-shaped labels.
4. Improve the processing technology to improve the tensile strength of leftover materials.
