Is It Important To Conduct Peel Strength Test?

The Peel strength test is a mechanical test that helps manufacturers measure the strength of the adhesive bond between two bonded materials. This test helps evaluate the performance of peel-off strips, adhesive tapes, labels, and other bonded materials commonly used in the textile and packaging industry. The test is usually performed with 90 or 180-degree angles. The test can be performed using a peel-strength tester instrument. There are advanced testers available in the market empowered with computer interface RS232 communication that connects the instrument to the computer to deliver comprehensive graphs.

What is Peel Strength Test?

The peel strength test can be conducted using a peel/bond strength tester instrument with high-end features to maximise accuracy in test results. During the test, a sample is bonded to a base substance and pulled apart under a controlled environment like controlled rate, angle, pressure, etc. A programmable logical controller measures the force required to peel the sample from the base substance. The test results are used to determine the strength of the bond. Invest in a tabletop model for easier access and portability.

How To Perform Peel Strength Test

Prepare the peel-strength tester according to the manufacturer's instructions. The testing instruments by Pacorr are user-friendly with easy-to-use controls. Adhesive bonds must fulfil its requirement. The user should not require too much effort to rip the bond apart. Alternatively, the bond should not be too weak to ensure the safety of the content it encloses. Therefore it is crucial to include the peel strength testing instrument in the packaging industry to ensure every package is packed with utmost precision.

The Peel strength test usually involves the following steps:

Step 1: Place the sample to be tested on the machine. Ensure the ends of the sample are held by solid clamps.

Step 2: The sample is pulled in opposite directions at a set load to facilitate a real-life pulling-apart scenario. The tester can define the pulling force and modify the speed controls based on their requirements.

Step 3: The instrument is enabled with S type load cell that takes care of the applied pressure to the specimen. It helps uniformly distribute the force across the specimen.

The microprocessor-based digital programmer facilitates accurate reading of the test performed. Typically a vice clamp is used within the setup. However, most manufacturers offer various types of clamps based on client requirements. The single screw mechanism machine paired with a reputed induction motor ensures smooth speed variation.

Final Thoughts
The peel strength tester is a useful instrument that helps determine the quality and performance of adhesive bonds in various industries, including packaging, automotive, and construction. Invest in quality testing equipment that produces accurate results. Pacorr is one of the foremost producers of testing instruments delivering high-end durable testing instruments worldwide. It can help to identify potential issues with the adhesive bond and ensure that products meet the required standards and specifications. The tester is equipped with an AC drive to control the peel-off speed allowing testers to record values that include load and elongation.
