Thread: Scotch Super 33+ for taping spines.

OK, here's something quite strange. I ran across the "core" or empty roll of the previous tape I bought. Guess what? It was 33+ also but I had no problem with that roll at all. My current roll must be of a different production batch or something. I would not expect a quality control issue from 3M but apparantly there are differences from one roll to another. Odd.

I like the Duck 0.007 mil one, no residue and I find it behaves at least as well as the super 33.

All physical processes will produce different outcomes due to natural variability - the only question is the magnitude of the variation and whether that is acceptable or not. A whole industry has developed around manufacturing and automation for just such purposes, known as Statistical Process Control. I am sure 3M are quite familiar with it, and have probably spent several millions of dollars over the years on it. That's just a guess though.

In any event, I favour the cheapest tape I can find. Currently that is a 5 pack from the local supermarket for 2 dollars. It may not be as durable as more expensive tapes, but when it wears out I can just replace it because it is pretty cheap stuff. It produces no glue residue at all, probably because it is so cheap the glue is basically flour and water...

i have found that mineral oil takes the residue of lickity split on my razors and leaves the blade protected. YMMV but its what i do! lol

I haven’t run across any tape residue that good ol’ Zippo Lighter Fluid wouldn’t remove.

But again, YMMV.

electrical tape if exposed to heat will leave a black residue .heat breaks down the adhesive

For what it was designed for, covering electrical connections, stickiness is a virtue, and 3M is probably the best electrical tape for what it was intended. Adhesives dry out, maybe the "old" roll was around for a while and the adhesive dried some, making it less apt to leave a residue.
