The brightness of the second, watching film, touch membrane thickness. In general, inferior adhesive tape products color dark than qualified tape will be many, and hand touch, generally inferior adhesive tape will be more hard, but also because the membrane is thick, the actual number of meters must be reduced. Good adhesive tape film are soft, good tensile properties. So, it is very important to the brightness and the thickness of adhesive tape two indicators, must observe carefully.
