Permalife® Bond Paper (75 gm2) is known for its durability and strength. It is made to exacting specifications and is ideal for museum and archival uses. This acid-free 20# white paper is produced from 25% rag, 75% wood fiber.
Acid Free Paper is paper that contains no free acids, thus providing greater permanence and durability. The paper is typically produced from cotton linters, rags, esparto grass, or chemical wood pulp which minimizes the potential for acid and/or lignin in the pulp. Acid-free paper may also contain a buffering material to maintain a pH in the neutral to slightly alkaline range. This helps scavenge any acidic materials formed by bleaching residues, sizes, degradation products, or air pollutants. It is rated to last 300 years in storage. This paper has been used successfully for hundreds of official applications submitted to NSDAR for Patriots.
