Archival Methods Archival White Paper, 120gsm, 11.6x8.2", 100 Sheets
Description
Over time, the integrity of your precious photographs, artwork, and documents is paramount. Adorama's Archival White Paper is meticulously crafted to ensure the long-term preservation of your valuable items. Made from high alpha cellulose pulp derived from purified wood fiber, this archival-grade paper boasts a substantial 25% cotton content, enhancing its durability and feel.Each sheet of this premium 120gsm, 11.6x8.2" paper is acid-free, ensuring that it will not contribute to the deterioration of the materials it comes in contact with. The inclusion of a 2-3% alkaline reserve, with a pH of 9 ±0.5, courtesy of calcium carbonate buffering, provides an additional layer of protection against acid migration and environmental pollutants that can compromise the quality of your stored items.This Archival White Paper has been rigorously tested and passes the Photographic Activity Test (PAT) according to ISO IT 18916 standards, confirming that it is safe for long-term storage of photographic materials. The sulfur content is impressively low at less than 0.0008% reducible sulfur, minimizing the risk of corrosion and damage. Furthermore, the lignin content, which can lead to paper yellowing, is kept in check with a Kappa number of less than five as tested by TAPPI 236 cm-85.Ideal for a multitude of applications, this acid and lignin-free white paper is perfect for creating album pages, interleaving between prints, or providing an acid-free lining where necessary. The National Archives and Records Administration (NARA) endorses the use of buffered paper stock for the storage of photographic materials, with the exception of cyanotypes and dye-transfer images, to prevent the natural acidification process that can occur with non-buffered paper.Recent studies underscore the importance of avoiding prolonged exposure to moisture for alkaline-sensitive photographs, a practice that should be standard for the preservation of all paper-based materials. With Adorama's Archival White Paper, you can rest assured that your treasured memories and important documents are protected, housed in a stable and secure environment that guards against the ravages of time.
