Hi,
Things are starting to get a bit tight. So I’m thinking of storing my black-and-white slides in Adofile-style slide sleeves instead of in boxes as I’ve done up to now. Stored in ring binders, they’ll certainly take up far less space. But are polypropylene slide sleeves suitable for the long-term archiving of glassless framed slides, or are they not really recommended for this purpose? Does anyone know more about this?
Regards,
Jo

Jo,
What makes ADOFILES and similar products suitable for long-term archiving is the chemical inertness of polypropylene.
It does not react with the films.
This makes it the most suitable material for long-term archiving.
Advocates of glassine sleeves repeatedly argue that mould can form in PP sleeves because PP is airtight. That is correct, to a certain extent. Under extremely poor storage conditions (fluctuating humidity, rapidly changing temperatures), condensation can form and encourage mould growth.
Anyone with such poor storage conditions would be better off using glassine sleeves, but the films will still suffer in the glassine sleeves under sub-optimal storage conditions and will not last very long.
The paper and adhesive used in the glassine sleeves are, as far as paper can be, acid-free and chemically inert.
Best regards,
Mirko
