Any ideas on how to unstick envelopes?

Question

I've got several boxes of business envelopes that have become stuck shut in the humidity. I'm looking for a tip less time consuming than holding each one over a steaming teakettle!

Answer 1

use a hot steam iron for about 5-10 seconds on each one.... peel flap gently open.

Answer 2

BRUTE FORCE!!!  Pull them open by hand/letter opener and tape them shut when necessary.  Next time you'll get the peel and seal, won't you ;-)

Answer 3

#dip in warm water for 10 seconds and try to open (longer if needed), let dry

#the steaming idea

#freeze them for about an hour , which will disable the glue so you can open it

# use a letter opening knife soaked in vinegar and carefully open

#spray liquid nitrogen, but i doubt you have that

#cut the flap off and just leave a small rectangle of the flap at the top, so it looks like this    http://www.suppliesforless.com/thumbs/PG...   opposed to this     http://tbn0.google.com/images?q=tbn:dCS6...

Answer 4

Put them in the freezer for a few hours.
