Very thin (.001) acid-free tissue with a 3% calcium carbonate buffer added. Buffering agent will help neutralize acids and prevent acid migration to the objects that the tissue is used to protect. Buffered interleaving tissue extends the life of paper, photographs, textiles, and artifacts. Use for most photographs, including black & white, color & albumen prints. Most items in storage, especially in the collectibles arena, would benefit from storage in a buffered enclosure. This is especially true for the vast majority of paper items. Because of its ability to neutralize acids and extend the life of paper, photographs, textiles, and artifacts, buffering is more often than not a benefit in interleaving tissue, storage boxes, folders, and other paper enclosures. For most photographic materials, including black and white prints, color prints, and albumen prints, either buffered or unbuffered enclosures are satisfactory.
