Conservation best practice suggests that tape needs to 'breath' as the binders holding the oxide to the tape backing also outgas. Cardboard boxes without plastics bags are what's used in archives - tapes stored upright in constant temperature and humidity. I would have through the Preservation...
Plasticisers come to the surface and do damage through contact but once there they vapourise and can damage anything in an enclosed space - like the inside of a plastic bag - there are lots of scientific papers on the subject in the conservation field.
Only if the paper was gas tight - which I suspect it is not. The plastic in ziploc bags can/does do dreadful things to photographic materials. Cutting a large piece of archival card into a cruciform shape and scoring/folding it to enclose the tape reels might be a solution but the corners could...
They'd keep the rain out and the tape in but they don't even come close to conservation grade. The soft plastics leaches plasticisers over time which may damage the reels or the tape. Only plastics like PET have any use in conservation. You might find 'memorabilia' bags at one of the UK family...
From a conservation point of view I wouldn't be using plastics - particularly soft plastics. Having lived in the US I know how very easy it is to get this kind of product there - Conservation Resources Audio Tape Boxes – #551MC- 771MC-1111MC - are inexpensive and good quality. You might try...
I would have though 29mile's D3500 would have been an ideal choice for her - not related.
Used to teach A level photography at a mixed FE/HE university college moons ago - I take it she's NOT looking for a film camera.

Thanks all - yes it's the last fitting in a looped circuit but there's no rose fitted so its just a bunch of wires hanging down into a very old piece of stripblock. Hence my caution.
Just taken a ceiling light fitting down. 4-way chocolate block in - commoned grounds; two twins from attic wired lives commoned but going nowhere; returns wired: one to live of light fitting - one to return of light fitting. Why?
I don't want to guess what I'll find behind the light switch...
Just notice this thread reactivated - FWIW I reviewed the 6000 system for HFN in 1986 if anyone wants a pdf just PM me. (Four acronyms/abbreviations in one sentence - not bad!) DGP
