Problems to be paid attention to when checking the quality of double-sided tape
Double-sided tape products are composed of three parts: substrate, adhesive, release paper (film) or silicone oil paper. The quality inspection of double-sided tape products should pay attention to the following aspects: 1. You can check whether there are burrs on the double-sided tape. Cut edge of double-sided tape. 2. You can check whether the double-sided tape has cracks. For example, due to the influence of factors such as improper adjustment of the cutting tool or insufficient sharpness of the blade, cracks will appear on the top paper or bottom paper of the double-sided tape, and the fibers pulled out from the cracks stuck with adhesive again. Because the cracks are small, they can only be found after separating the backing paper and the top paper, so it is only necessary to ensure that the knife is adjusted in place and the sharpness of the blade is ensured. 3. You can check whether the edge of the double-sided tape is stuck and whether the backing paper is missing silicon. 4. Check whether the slitting end of the reel double-sided tape is straight and whether the rewinding is tight or not. For example, the slitting end face of the reel of double-sided tape is uneven, which affects the registration during processing, and it is difficult to discharge waste due to the change of the die-cutting position. Inconsistent tightness during rewinding will cause tension changes and cause product quality problems.
