Metal Adhesion Strength of Metallized Films, Peel Tests

摘要

1. 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. 2. 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. 3. There is still a considerable amount of work to be done about development of adhesion tests.
