This high-purity, 100% cotton all rag sheet was developed to meet the highest quality standards for the storage of photographs, textiles, and works on paper. Made in a very smooth finish to prevent damage to negatives and prints by abrasion, this natural white, cotton rag paper is unbuffered and sulfur-free. Fiber distribution and formation of this paper is excellent. The pH at the time of manufacture is 7.3. Since the paper is not buffered, a drop in pH-value is to be expected when exposed to normal atmospheric conditions. This tissue passes the Photo Activity Test of ANSI Standard IT9.2.
The sheet stock measures 24" x 36" and is packed 100, 250 and 500 sheets per carton. Roll stock is 55" in width and 250 yds in length.
