Sealing is to use BOPP pressure-sensitive adhesive tape, which specifies the product classification, technical requirements, test methods, inspection rules and signs, packaging, transportation and storage of sealing tape (hereinafter referred to as 'tape'). The sealing tape is a tape that uses a biaxially oriented polypropylene film as a base material and uniformly coats a layer of pressure-sensitive adhesive on one side of the base material. The tape is mainly used for sealing boxes, capping and binding items, etc., and can also be used as office supplies. The test method of adhesive tape is as follows: 1. Initial adhesiveness: that is to test the initial adhesiveness of the adhesive tape to the adherend. The general method is to use a national standard steel ball to roll down naturally on the adhesive tape inclined at an angle of 45 degrees, and increase in turn. The size of the steel ball, the larger the steel ball it can stick to, the greater the initial adhesion. 2. Stickiness: After the tape sticks to the object completely, the stickiness of the stickiness, the usual test method is: use the tape of the specified size to stick the surface of two steel plates, then hang one steel plate on the tester, and the other Hang a 1KG weight to see how long the two steel plates are not separated. 3. Peeling force test: Use a tape of standard width to stick a specific steel plate, and then use a robot to tear the tape off the steel plate. The stable force of the manipulator reflects the peeling force.
