1. When cutting the double-sided adhesive tape, if the cutting tool is not properly adjusted or the blade is not sharp enough, cracks will appear on the face paper or bottom paper of the double-sided adhesive tape, and the fibers pulled out at the cracks will be stuck by the adhesive.
2. The occurrence of cracks in the double-sided adhesive tape may be continuous or random. It may occur on one side or both sides of the roll of double-sided adhesive tape. Therefore, before machining the double-sided adhesive tape, it is not possible to carefully check whether there are small cracks on its backing paper and face paper.
3. Take a section of sample paper that has passed the above inspection, peel it off the base paper and check again whether there is any crack on the top paper and the base paper, because the crack on the double-sided adhesive tape is sometimes very small and can only be found after separating the base paper and the base paper.
