1. Look at the total thickness of the tape. It can be measured with a tape caliper.
2. Look at the tension of the tape. The method is to place the tape on both ends of the tape tensioner and start the test. The data obtained when the tape is broken is the tensile strength of the tape.
3. Look at the adhesive (ie, sticky) of the tape. The method is to place the tape on the tape detector and start the test. The data obtained when the tape is peeled off 180 degrees until the tape is detached is the viscosity of the tape. Generally expressed by steel ball number, such as 7N is 700g.
4. Look at the peeling force of the tape. The method is to place the high temperature tape on the tape detector and start the test. The data obtained when the tape is peeled off 180 degrees until the tape is detached is the viscosity of the tape. Generally expressed by steel ball number, such as 7N is 700g. Another way is to take a piece of tape and seal it on the box. Whether the tape is easy to break, whether the surface of the carton can be destroyed after tearing, the ordinary sealing tape in daily life.
