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. This Permalife® permanent archival bond paper is not only Acid Free but is also Lignin-Free & Buffered (with a 3 to 4.5% calcium carbonate reserve).
The paper is excellent to use for end sheets, interleaving, photocopying, lining of drawers and cabinets, and general wrapping. Recommended for a variety of uses including printing (letterpress or offset), writing (pen and ink with excellent erasing qualities) or folding (exceptionally strong paper). This is the paper that's used most frequently for doctoral and masters' theses. Often used inside time capsules, not only for properly photocopied items and clippings of interest but for original messages and even, in some cases, cushioning inside.
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.
We recommend you use this paper for your time capsule needs. It is 25% cotton, acid free, and rated to last 300 years. The 20 lb weight is not as heavy as 24 lb - however there will not be heavy usage while in the time capsule.
This is the same fine paper that we include in our preservation kits.
