Nope. They just fall apart after some time, usually a few years. You come out way ahead not keeping a lot on hand and buy them as needed.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

I use a 6 x 48 stationary belt sander for plastic and aluminum. I have gotten one dozen belts every ~two yrs. from
Industrial Abrasives. I keep them in their shipping box in a closed cabinet in my quasi-climate controlled shop and I have not had one fail.

Now you tell me
If it can't kill you it probably ain't no good. Better living through chemicals.

I have had some 3M for 10 years, sit in a hot garage in the summer, cold one in the winter here WI. Never a problem.

The SO asked me today, "what are you going to do to day"? I said "nothing". She said, "that's what you did yesterday"! Me, "Yes love, but I was not finished yet"!!!!!!!!

Kinda seems like the glue deteriorates with age.
on some brands of belts, yes, it does.

IME the width and length of the belts has more to do with failure over time. The joint is just too short and the adhesion seems to release with heat and friction
I was in a bind one day for a couple of 150g Belts and went to a local repair shop that had them.
I knew they would not last more than an hour when I took them out of the sleeve.
I expect they were 10+ yrs old and I was right they all failed at the joint in less than an hour
Let us not seek the Republican Answer , or the Democratic answer. Let us not seek to fix the blame for the past. Let us accept our own responsibility for the future John F. Kennedy

Yup. The klingspor ones I bought flew apart within seconds of use. The rep replaced them and said it happens allot. Haven't bought their stuff since. The lap joint ones last longer but have that bump during use.
Now I have cheap ones I bought at the woodworking shows 10 years ago... Just dug them out and they work just fine. I use 4x24 belts. Thought of getting the baby 3x 21 as its lighter and belts are more readily available locally when needed.

Well that is because you bought good quality belts with top of the line mylar tape. All other belts use junk adhesive and cheap Chinese mylar. Some of them don't even use mylar that has fibres in it that go the direction of the belt.
Although even 3M's belts will supposedly only last 10 years but I am using some I made myself 11 years ago and they are still going strong. And I am not a good belt splicer (doing it by hand) so if I can get 10 years, the factory splicers should be able to do the same.
If the tape peels off the backing, it is the resin/adhesive on the splice tape that failed.
If the tape splits in half, it is the wrong tape.
If the belt breaks just at the edge of the tape then the belt was skuffed too deep.
If the belt breaks anywhere not near the tape/splice, then it is the backing that has failed.
