Based on my experience, the foil wrappers are no picnic either-- after many bad experiences, on a tip from my gal Martha, the only caramel wrappers I use are the twisting wax paper from Candyland Crafts:
http://www.candylandcrafts.com/twistingwaxpaper.htmSounds like you normally use something similar. I gave all my foil wrappers to my 1st grader for craft projects.
As for salvage, you could make caramel sauce by adding some cream to the sticky caramels and heating it. You could either try to scrape the caramels off the paper before adding them to the cream, or try heating cream with the papers and caramel. The latter approach is risky, as the paper might disintegrate. With the time you invest, you might just be able to make a fresh batch of caramel-- luckily the ingredients are not so expensive!
Good luck and do report back! That reminds me, I need to get a batch of sea salt caramels going for teacher gifts-- holiday break is coming FAST!!
