Becky,
See the WAML Map Librarian's Toolbox site here: http://www.waml.org/maptools.html
Under the N-Z column is a link to Preservation supplies. Perhaps this will help?

Subject: Aerial photo poly sleeves
We have some odd (for us) sized negatives that we need to get into poly
sleeves for protection. They are 9.5 by 9.5 inches. We are not having
any luck finding sleeves this size. Does anyone know of, used in the
past, have a good guess where we might get such sleeves?
Many thanks for any thoughts.
