The paper is excellent to use for time capsules and long term storage projects. If your project entails frequent paper usage, consider the 24 lb weight rather than the 20 lb.
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.
