Storing slides

I am the Collection Management Librarian at the National Library of
Medicine, and am looking for storage boxes made of polypropylene or
other archivally safe materials to house slides stored in carousels.
We currently have the vinyl slide carousel holders in our
collection, and would like to replace them with archival quality
boxes.  Does anyone have any suggestions or sources for this type of
housing?  Thank you very much,

Mary Kate Dugan
