It was much thinner than DECTape, and we had print-through issues of tapes that were stored for a few weeks. That seemed to clear up if the tapes were then used again. I guess the permeability was not as high as real DECTapes.
It may also be a case of wrong shape hysteresis loop. And standard tape isn't usually sandwich tape as DECtape is, so it would wear fast.
