Cotton paper wrapping for microfilms

Leírás

A wrapping used to secure microfilm reels is a perfect protection against damage and accidental unreeling. It is a classic and very simple packaging made from cotton paper. This material does not contain an alkaline agent - calcium carbonate - owing to which it is perfectly neutral and can come into contact with chemically "agressive" photographic materials.
