Metal adhesion strength of metallized films, peel tests

• There is a lack of test methodologies for metal adhesion on polymeric substrates. Current measurement; standards are largely Incomplete. Available EAA-peel tests are not always applicable by the metallizing companies due to the overstretching of the EAA-film during the peel test. Mechanically stronger heat sealable | films may be more promising. • Peel test results of laminates are influenced by several factors, which are usually not recorded during the; measurements such as peel distance, peel-off angle, thickness, elastic and viscoelastic properties of the! peeled material. Relations to practical load conditions are still not known. • There is still a considerable amount of work to be done about development of adhesion tests.
