PEEL STRENGTH is a material's ability to resist forces that can pull it apart by separating a flexible surface from a rigid surface or another flexible surface.
Peel tests are useful for a variety of products and can be performed on containers such as jars, cans, trays, packaging pouches as well as assessment of adhesive, cosmetic and medical products such tapes, bandages, wax strips etc. The most common tests are the T-peel, 90 degree peel and the 180 degree peel strength test but different peeling angles are possible. Usually the average force per unit width and the peak force required to separate either of these two surfaces is measured.
Typical properties that can be obtained from a texture analyser graph:
Peel Strength, Force to Commence Peeling, Mean Peeling Force
Typical Texture Analyser graphs with annotated properties of 180 tape peel and packaging opening tests
Typical Probe/Fixture used for Measurement:
The above are only typical examples of peel strength measurement. We can, of course, design and manufacture probes or fixtures that are bespoke to your sample and its specific measurement.
Once your measurement is performed, our expertise in its graphical interpretation is unparalleled – no-one understands texture analysis like we do. Not only can we develop the most suitable and accurate method for the testing of your sample, but we can prepare analysis procedures that obtain the desired parameters from your curve and drop them into a spreadsheet or report designed around your requirements.
