Hey Geoff. I personally do not use ziplock bags because they contain PVC which will leach out & damage the items. It is much better to use some other long termed archival bags. The PVC contained in most bags will leach out in time & cause brown spotting on many materials. You can do a Google search on "archival storage bags". I buy my archival bags at a local high end picture framing shop. Hope this helps.
