To determine whether the adhesive performance of the tape is qualified and meets the requirements for use, the main 

focus is on three indicators: peel strength, initial adhesion, and holding adhesion. Peel strength refers to the force

 required to peel a certain width of adhesive tape from a specific surface of the adhesive material, and is one of the 

most important indicators of the tape.

What testing instrument is used for peel strength testing

The peel strength of adhesive tape products can be tested using the adhesive tape rolling machine and electronic 

tensile testing machine ETT-A developed and produced by Puchuang Industrial Technology.

Testing instrument: Electronic tensile testing machine

Test steps for peel strength testing method

This experimental method tests the peel strength between tape samples and stainless steel plates.

(1) Place the adhesive tape sample in an environment of 23 ± 1 ℃ and 50 ± 5% RH for 24 hours of state adjustment.

(2) Wipe the surface of the stainless steel plate with acetone 4 times and let it air dry for 10 minutes.

(3) Remove the 4 layers on the surface of the adhesive tape sample, and use a cutting knife to cut a sample with a 

width of 24 mm and a length of 300 mm from the remaining sample.

(4) Fold one end of the cut sample with adhesive to form a folded layer approximately 12 mm long. Stick the other 

end of the sample onto one end of the steel plate and roll it twice with an adhesive tape roller at a speed of 600 mm/min.

(5) Peel off approximately 25mm of adhesive tape from the steel plate at the folded end of the specimen, and clamp 

the steel plate at that end and the free end of the specimen separately in the upper and lower fixtures of the electronic 

tensile testing machine.

(6) Set parameters such as test speed (300 mm/min) and sample width (24 mm), click on the test option, and the test 

will begin. The equipment will automatically record the force values during the peeling process and report the peeling 

strength of the sample accordingly.

(7) Repeat steps (3) to (6) regarding sample cutting, preparation, and testing, and test the peel strength values of three 

samples.
