I mentioned this in another post and someone thought it might be worth a TOTW attempt so here it is..it's save all tinters $$ if your in flat glass or automotive..especially if you ordered specialty film that you don't use often , but you paid for it.
I've kept partials for yrs without separation :
1.Make sure the film it dry B4 storing
2. Place it inside a core tube with about 3 small moisture bead packs
3. Wrap that up with the plastic bag that comes with your film when you buy it
4. replace end caps (this makes a relatively airtight seal for any moisture entering and the beads locked inside takes care of any moisture when packed)
5. Place lid on
Will last for a long time and save $$$
