First of all, you can smell the smell of kraft paper tape. If the smell is strong and has a sour smell, this kind of destructive tape has very poor holding power, especially in low temperature environments, and it will basically crack when it sticks to the carton. Then, you can feel the thickness of the film with your hands. The tape that feels hard is generally inferior, and due to the thickness of the film, the actual number of meters will decrease. The films selected for good quality tapes are relatively soft and have good elongation by hand. .
In addition, you can also look at the color of the kraft paper tape. Generally, the whiter the appearance of the transparent tape, the less impurities the tape has, so as to ensure normal adhesiveness.
