This heavy white sheet is Buffered, AcidFree & LigninFree and insert dimensions about 13-1/8" x 23-1/2" hand-cut.
100% cotton museum-quality AlphaRag Artcare sheet that features MicroChamber "zeolite" Technology. Meets the regulations of ANSI/ NISO Z39.48-1992 (Permanence of Paper) AND passes the Photographic Activity Test (P.A.T.). No optical brighteners are used in the manufacturing process. The MicroChamber products incorporated in this heavy paper effectively remove many harmful compounds such as phenols, ethanoic and methanoic acid, sulfur dioxide, ammonia, and formaldehyde, which contribute to the aging of artwork and other materials (including newspapers).
Paper is AcidFree, LigninFree, Buffered to impart a pH protective backing, but it does much more. Its thickness is 1 pt, so it's not overly thick nor is it too thin.
Add a slightly larger inert plastic closing bag (i.e., polyethylene or polypro) to make your own kit (see our premades 11364 & 11366 sold separately).
Your order comes to you packed in a plain non-closing plastic bag.
