Your lucky these are small pieces, the only method I have used that was
successful was soaking in cold water for several days to a week or more.
This will break down cellulose which can then be rolled off with the
palm of your hand (kind of like rolling a buger between your fingers).
Yes the adhesive will come off at the same time.

Anybody had any experience Peeling Protective Paper from
Plexiglass??---When it's old & dried out---everything I've used to try
to soften the old glue also softens the plexi & leaves it with an
orange-peel finish. I have several 12" sq pieces, the center will
finally come once you get out there, but the edges are no-luck.

Thanks in advance
