Many types of tapes are used in packaging industries for sealing purpose such as printed fragile tape, PVC tape, Kraft paper tape etc. A peel test is conducted to check the adhesive strength between two flexible medias. The flexible medias can be rubber, polymers, tape, plastic material etc. Various conditions within which these materials are tested consist of many combinations of temperature, pre-treatment, and test speed depending on the standard. The strain rate differs with the loading rate in most adhesives. Fast peel test will damage the adhesive high peel force due to its elongation and slow peel test will stretch the adhesives due to low peel forces.Peel strength tester is effective testing machine to examine the peeling strength.
The purpose of peel tests is to check the adhesive strength between the two materials. The result can be used to analyse the firmness of the adhesive bond. Peel test gives accurate result to analyse the performance of adhesives, laminates and seals. The product performance and parameters of processing for example application of adhesives and curing ensure safe usage of products and conduct according to expected specifications keeping in mind the brand image.
