Sorry for the late reply
DW Viewpacks http://www.dw-view.com and Secol http://www.secol.co.uk both supply archival quality photo holders of the kind you are looking for.
By archival I mean the materials they are made from have been rigorously tested, certified and are accepted by museums for deposition. As a very basic rule, if the plastic 'smells' in any way, it is giving off vapours harmful to your photos.
We still archive slides and medium format negs this way. I note that some museums are now requiring digital photos are printed professionally and then archived in the traditional manner - that or back to film!
