Adhesive tapes are now widely used in carton packaging, parts fixing, and sharp object bundling. Good adhesion can avoid the phenomenon of delamination of the adhesive tape and the adherend during use, especially in high or low temperature environments, this delamination phenomenon is more common.
Peel strength is the force required to peel a unit width of adhesive tape from a specific adhesive surface at a certain angle and rate, in N / cm. As an important indicator of the adhesiveness of the adhesive tape, the peel strength can provide more information about the performance of the adhesive tape and its expected behavior compared with the initial adhesion and the holding viscosity.
In terms of evaluation test of adhesive tape peel strength, GB / T2792-2014 "Test Method of Adhesive Tape Peel Strength" provides five kinds of test methods, 90 ° peel strength test is one of them. Below, we demonstrate this test process using Labthink BLD-200N electronic peeling machine.
The unwinding strength reflects the applicability of the adhesive tape in the automatic packaging machine. If the unwinding strength is too great, the adhesive tape will break and stretch to varying degrees, affecting production efficiency. When pasting and applying, quality defects such as shrinkage and unevenness will also occur, which will affect the bonding effect and bring about hidden quality problems.
Next, we used Labthink unwinding strength test fixture and tested a certain adhesive tape sample with reference to GB / T 4850-2002 "Determination of low-speed unwinding strength of pressure-sensitive adhesive tape".
Strengthening the monitoring of the adhesiveness and unwinding performance of the adhesive tape is of great significance for improving the product quality of the adhesive tape and improving the applicability of the machine. Labthink is committed to helping customers cope with packaging problems through packaging testing technology improvement and cutting-edge testing instrument research and development, and helping the quality and safety of packaging related industries.
