GLASSINE NEGATIVE BAGS & SHEETS

Glassine is not to be regarded as an archival material, although it is still the mainstay of many an old collection. In its favour, it is soft, so unlikely to abrade the negative, and the sulphur it contains is reasonably well locked up, so you are unlikely  to see any significant deterioration in silver images over a few decades. On the other hand, if it gets wet while in contact with with the emulsion you have got problems, and it will be very difficult to avoid marks even if the film is carefully rewashed. The file sheets are 4-hole punched to fit into the cheaper PVC files, or the ARCHIVE RING-BINDER BOXES.
