That sounds right.  It’s the same stuff used for DECtape; we called those LBTs (“little blue things”).  They work for 1/2 inch magtape provided the backing is glossy, not the matte stuff that some manufacturers used.

I believe it’s the same stuff that you can find in window decals, like the ones of animals I had as a 4 year old.
