The tapes are distinguished according to the stickiness: single-sided tape and double-sided tape; the second is to look at the color and brightness. The color of the inferior tape is dark. Dark tape has a high chance of cracking. Generally speaking, the whiter the color of good-quality tape, the better. There are few impurities in the tape, and the quality of the tape with high transparency is relatively good. Appearance and smell are different. Open a roll of tape to see if it has a soft film thickness. Maybe we feel that the harder the tape film, the better. In fact, on the contrary, the harder the tape, the easier it is to crack, and the better the hand stretch rate of the soft tape.
After opening the box, smell it first. If there is a sour taste, this tape has poor retention. At low temperatures in winter, the tape can become very brittle and crack in appearance, causing it to break as soon as it is pulled. Over time, the glue on this tape dries out and loses its viscosity.
