General Testing Technology In Adhesive Tape Industry
Sealing tape has become an indispensable product in packaging, but due to technical problems, the quality of sealing tape produced and sold by many manufacturers is also uneven. So what should we pay attention to when buying sealing tape? How to test the stickiness of sealing tape?
The oven-type tape retention tester performs a static load test on the adhesion of the adhesive tape, and automatically counts the time the tape can hold under a certain load and temperature to confirm the aging of the adhesive tape. Cut a 1-inch-wide strip of tape and paste it on the specified SUS#304 stainless steel plate, roll it back and forth three times with a 2kg standard roller at a speed of 300mm per minute, hang the steel plate on the testing machine, and add the specified weight , when the tape falls from the steel plate, the timer automatically retains the test time, which is used to evaluate the persistence of the tape adhesion.
The tape retention testing machine sticks the tape to the test board, hangs the weight at the lower end, and measures the sliding distance of the tape after a certain period of time.
The initial tack of the sample is tested by the adhesion of the tape to the steel ball when the steel ball and the sticky surface of the pressure-sensitive adhesive tape sample are in short-term contact with a small pressure by using the inclined-plane rolling ball method. This machine uses the rolling distance of the steel ball on the tape fixed on the inclined plate to test the stickiness of the tape to judge its quality, and record the number of balls that can stay on the tape for more than 5 seconds.
The tape peel strength testing machine is a mechanical performance testing machine for static load, tension, compression, bending, shearing, tearing, peeling, etc. of instruments and equipment for various materials. The tests yield precise results—force, elongation, tensile strength, peel strength, tear strength, compressive strength, and more.
