Archival Glassine negative sleeve pages for 120 format film, 25 pack of 4 row sheets[BDER]
Glassine film Negative Sleeves for archiving 120 medium format films. Glassine is a paper based product. 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, because glassine can breathe. This generally makes glassine sheets more suitable for archiving than acetate. Overall sheet size is 250mm x 310 mm.
