They breathe better if you do not have them sealed when you are baking them..ed _www.smecc.org_ (http://www.smecc.org) (resent due to error message) Original message From: Chuck Guzis ccl...@sydex.com Date: 06/09/2015 9:46 PM (GMT-07:00) To: gene...@classiccmp.org, discuss...@classiccmp.org:On-Topic and Off-Topic Posts cctalk@classiccmp.org Subject: Re: Blue tape retainers On 06/09/2015 08:21 PM, ben wrote: Also would not a fall like that damage the tape reel? 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. --Chuck

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. -- Mark J.

I have had them come inthem for video tape too and they were seem to be white vinyl in this case Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 6/9/2015 5:04:47 P.M.

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?

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? Ben.
Re: Blue tape retainers
wonders how long it takes the seal to decay? when in the biz had tapes on the rack for 13 years and no falling . Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 6/9/2015 7:42:06 P.M.

Eventually the white material will fail, or the black lock will break, but they are by far the longest lasting other than just a clear box container. Every couple of years for awhile now I'll be surprised in hearing a snap, clunk and strange scuffling sound in the house.

After a few years, they start looking for food. :)
