Not sure about "archivalness" but the harder the plastic, the more inert
the plastic. Softer the plastic, more plasticizers are given off; Thus
the colored very-hard plastic lab bottles popular for water bottles.

We use the semi-soft cases; called "clear/crystal" They seem to be
harder than the soft smoky ones, and I like being able to read labels
easier. They are available from a few different vendors for under $0.20
each.

Subject: [ARSCLIST] Advice needed on audio cassette cases

Dear Collective Wisdom,

Does anyone know if audio cassette cases are archivally safe? I'm not
meaning archival storage boxes for multiple cassettes---I mean the hard
(or sometimes soft) plastic cassette housing cases.

We have a special collection (recently donated to us) of hundreds of
cassettes in which the plastic cases are broken and need replacing. My
colleague, who processed this collection, is suggesting we purchase
Norelco soft poly boxes. You can see them <a

c987077b618dd874bc423> here</a>.

What do you use? Is there any archival information on these cases?

Any information would be greatly appreciated.

Thank you,
Ashlie Conway
