Materials for clamshell boxes

The Folger Shakespeare Library is preparing for a rehousing project
for many of its rare items.  As part of our planning process, we
have begun investigating the longevity of materials commonly used in
the creation of archival clamshells.  While we have already gathered
sufficient information to decide upon an adhesive and millboard, we
are still attempting to gather information on covering and paper
lining materials. After performing a few simple in-house tests, we
have narrowed our covering material options down to the following:

    Canapetta, color 1411
    Asahi, color 2499B

We have also decided on the following paper stock for further
investigation:

    Heritage Archival pHotokraft in Old Grey Ivory, both the 170 and
    350 gsm weights

At this time, we are interested in determining if anyone in the
conservation/preservation community has tested these materials
already and are willing to share the results with us.  We are not
interested in a specific type of test but instead would like to know
what range of tests have been performed and the results.

We would also be interested in any procedures/protocols that
institutions have developed for material selection and construction
of their archival clamshells.
