Terminate the main use of tape in industry

The termination tape is made of soft polyvinyl chloride (PVC) film as the base material and coated with rubber-type pressure-sensitive adhesive. It has good insulation, flame resistance, voltage resistance, cold resistance and other characteristics. It is suitable for automotive parts. Wire, wire winding, insulation protection, etc. The optical phenomenon when light passes through the center and the edge of the tape is different, because the center of the tape is theoretically a homogeneous medium, while the edge of the tape, especially the critical part of the tape edge, is an inhomogeneous medium, which will produce different degrees of light scattering, refraction and diffraction. phenomenon. At the same time, there will be a circle of air layer around the edge of the imposition tape. This air layer produces a difference in optical path and causes light interference. These will result in underexposure at the edges of the tape.　　In the process of terminating the use and placement of the tape, dust and other dirt adhere to the side of the tape, causing additional light blocking and light absorption, and further causing partial underexposure. In actual work, especially when the environmental conditions are poor, you often see obvious dark edges on the edge of the tape. The original plate of the tape collage must be printed with the print tape.
