When baking tapes with the Wright Line seals, I've  learned to remove the 
seals.  If you leave them on, the tapes at 58C,  will often just fall 
right out the seal--the coefficient of expansion is  much larger for the 
seals than for the tape reels.  After the seal has  had a chance to cool 
off, it fits fine.

This is particularly a  problem with the smaller size  reels.

I finally succeeded in putting a name to where I've seen that clingy 
vinyl material before--in a children's toy:


Google:  Colorforms

Interesting. I don't think I've encountered that style before, or if I did, 
that memory has snuck away in the night.

 It seems to me that I've seen it in the form of letters to be stuck to 
 windows.

That looks really promising. It would probably be easy to slice into neat 
strips with one of those circular-blad paper cutters from the local office 
supply store.

 One thing that I recall is that many tape  manufacturers used a blue,
 sort of sticky silicon tape to hold  ends in place.  This stuff never
 seems to  degrade.

 Since I used to buy them, I can say with some  authority that (1) they're
 vinyl tape, as others have surmised, and  yes it's the same stuff that
 adhesive-free window stickers are made  from, and (2) they came in lots
 of colours - I have almost every one  except purple, and, oddly enough,
 blue.  So the item on Amazon  might be a very good option.

Have you checked the places that sell  professional audio reel 2 reel  tape?

Hmm, the NOS 3M 777 tapes that I got off eBay have that one seals. Did 3M 
later switch to Wright Line seals? Off to google pictures of random mag taps

If it is generally UNwinding the tape as it goes, the reason is exactly
the same as why buttered toast always falls buttered side down:
   It is NOT due to the aerodynamics during the fall.
   It is NOT due to the center of gravity.
It is because you are winding it the wrong way around - (or
buttering the wrong side)


Also would not a fall like that damage the tape reel?

 Every couple of years for awhile now I'll  be surprised in hearing a
