Archival Glassine film negative sleeve pages Large Format 4x5 inch sheet, 20x4 frames[BKD]
Glassine sleeve pages for archiving large format sheet film negatives 4x5" (10.2x12.7cm). These sheets are made of finely-ground pulp paper which is largely greaseproof, but has a low wet strength. The high level of transparency is achieved by a special mechanical treatment called calendaring. Our glassine sleeves are made of acid- and lignin-free photo glassine. The main advantage of glassine over acetate is the ability to allow any moisture which may find its way in to evaporate again. This generally makes glassine sheets more suitable for archiving than acetate.
