You need to very carefully dry it, possibly with a re spooling to destress, and then keep it at or below 18C, but it has to be stable. Though the same applies

Though the same applies to polycarbonate/acrylic-glue BD-R.
If you do that they'll keep for centuries, at least the tapes that use oxygen resistant magnetic particles like BaFe (not MP).
Calcium oxide aka burnt lime is a cheap non-toxic (but caustic!) desiccant that can keep an e.g. paint can dry for centuries.

I find it entertaining that high speed magnetic tape - a technology in the consumer space that is basically obsolete is still one of the optimal solutions for "I have hundreds of terabytes of data I need to be able to read in 15 years".
