for Cold Storage of Photographic Material
Bags for cold storage of photographic
material are available in a variety of sizes. We have detailed information
which we will be happy to send upon request. This information was kindly
provided by Siegfried Rempel, author of The Care
of Photographs (see our book section). Cold storage is recommended
for color materials in particular because the organic dye systems upon which
these prints are based are prone to chemical deterioration at a more rapid
rate than non-color material, which are usually done in an inorganic metal
system. The rate at which chemical reactions occur slows as temperatures
fall, hence the reason for cold storage. The prints to be stored should be
placed in a cold storage bag with a laminate structure featuring paper on the
outside, a center layer made of foil, and a polyethylene layer inside.
Complete instructions are available. Freezing pouches are available in three
different sizes to accommodate most print sizes.
