I have worn myself out trying to find a standard. I swear, I have seen it before, but for the life of me I cannot find it out there at all (ANSI, ASTM, no where).
We print (screen and flexo) on flexible materials (PVC, tyvek, PE, PU, etc.). We perform and our customer performs a "scotch tape test" to check the adhesion of the ink to the substrate. We perform our test by applying the tape and peeling back at a 180 degree angle (or as close to 180 as possible). The customer does basically the equivalent of a "clean and jerk". There is a definite difference in the reaction of the ink.
I know that I have seen a standard somewhere for performing this scotch tape test. I did not get this 180 degree angle from "out of my @$$", but I cannot find the standard anywhere. I can find an ASTM standard for testing print on packaging materials, and also one for cross-cut or hatch tape testing. But we are not cross-cutting this substrate (we do for other tests, but that's beside the point).
Is anyone familiar with the scotch tape test and where I might find a reference or standard for performing this test. I'd like to "convince" our customer to modify their test method to match ours, provided that I can find some sort of guidance document to back up our method.
Thanks in advance for any guidance.
