Tupperware is known in Europe too and at the Central Laboratory in
Amsterdam (laboratory supporting conservation of works of art) a lot of
investigations have been done into plastics. Tupperware is made of
polyethene, this plastic will turn sticky, smelly and discolour over time.
So I would not use it if I where you. The concept of drying photos and then
putting them in a sealed box is a good one if a stable climate is
maintained ant the box is really air/gastight. These boxes will be costly
therefore.
Bags sold as archival should be good, I think Light impressions know what
they are doing and selling. See also addresses I gave before.

nice stuff to keep your photos next to eh?? Insects will drop dead from it
or not want to go near. Andthere must be some of it in the air, I do not
know of any research done as to the safety of this compound near photo's
but reading this (and other books) I would not recommend it unless the
plague does more damage than this cure.
