3. Glue

Look at the glue. Now most of the glue has evolved to environmental protection. If the smell is pungent, it is more likely to be a defective product (not all tapes).

It should be noted that the PVC materials used in the electrical insulation  Adhesive Tape are basically the same, mainly depending on the glue. After the tape with poor quality is wrapped for a period of time, it can be seen that the glue and PVC materials are separated, which looks sticky and uncomfortable, while the tape with good quality will not have this problem.
