Question about DECtape formulation

Back in 1971 or so, we had a PDP-5 with DECTapes, and bought 
3/4" analog recorder tapes surplus to make up new tapes.  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.
