Phase Box

Phase boxes are used to effectively and economically protect brittle or deteriorated volumes. They are custom made from non-groundwood pulp, lignin-free, archival grey/white board, pH 8.5, with a 3% calcium carbonate reserve. The grey/white board used in our Phase Box product has passed the Image Permanence Institute’s Photographic Activity Test (PAT), (ISO Standard 18916), and is safe to use with photographic albums. Titling is printed directly on the board and the enclosure is sealed with ties or Velcro tabs.

Phase Box Deluxe

The Phase Box Deluxe incorporates our standard Phase Box structure but includes a case binding cover for durability and increased rigidity. The case is covered in grade F library buckram and titling is printed directly on the cover.
