We use PE foam tape every day. It is widely applied in daily life and is also extensively used in industrial production. However, for many merchants who have purchased a large amount of tape, they are still not very familiar with the quality inspection of PE foam tape. Today, Engineer He Xing will take you to understand how to check the quality of PE foam tape: methods for inspecting the quality of PE foam tape. First: Check if there are any cracks on the PE foam tape. When slitting PE foam tape, if your slitting tool is not sharp enough or is not adjusted properly, it is easy to leave cracks on the backing or surface paper of the foam tape. Moreover, the fibers pulled out from the cracked areas will also be stuck by the adhesive. There are two possibilities for cracks to occur: one is continuous and the other is random. Sometimes they may appear on one side of the roll of foam tape, or on both sides. Therefore, before the PE foam tape is processed on the machine, we need to carefully observe whether there are any cracks on its surface paper and backing paper. Second: Check whether the PE foam tape has burrs, the smoothness of the edge of the roll foam tape, and whether it is damaged. This is the basis for ensuring the good quality of the double-sided tape. Therefore, before processing, we need to carefully observe whether there are burrs on the edges of the roll foam tape and whether it has been damaged due to improper transportation
