Talking about the importance of tape retention - 1

The so-called tape holding force is usually reflected by the sticky performance of the adhesive tape. When a weight of a specified weight is vertically suspended along the length of the pressure-sensitive adhesive tape pasted on the adherend, the adhesive tape resists displacement. It is expressed by the time for the test piece to move a certain distance or the moving distance within a certain period of time. As an index for testing pressure-sensitive adhesive tapes, stickiness can also be used as an index for testing pressure-sensitive adhesives. The stickiness of the tape is closely related to the quality of the product. If the stickiness is poor, the tape will easily fall off and the purpose of the adhesive tape cannot be achieved; if the stickiness is too large, it is easy to be a sticker. It is damaged when the sticker is released. Adhesion is a complex physical and chemical process. The generation of adhesive force depends not only on the adhesive, but also on the adherend and the operation process of the bonding. Therefore, in the test process, various influencing factors should be fully considered and the operation method should be unified in order to obtain accurate and reliable test results.
