Corona-treated film test
The American Society of Test Methods (ASTM) announces the approval of a new test method for determining the surface energy of corona-treated films. The new test method, ASTM5679-96, is entitled "Test Method for Corona-Treated Polymer Films Using Water Contact Angle Measurements." Method allows for the inclusion of measuring all polymer films, unlike the older test that measured only PP and PE films.
