Phase Boxes

Phase boxes are archival boxes used to effectively and economically protect brittle or deteriorated volumes. They are a custom made, four-flap enclosure available in grey/white or tan barrier board.  They can be closed with ties or hook & loop buttons. Titling is foil stamped directly onto the board.  Phase boxes are available in standard and deluxe versions.  The minimum thickness for phase boxes with ties is 1/2″.  The minimum thickness for phase boxes with hook & loop buttons is 3/8″.

(Almost) No Box Too Big or Too Small

While there have been boxes that are too big or too small for us to make, we rarely run into that problem.  Even items that are larger than our sheets of board can be pieced together.  Additional fees may apply for these monster boxes, but we love a challenge!

Archival Protection

We use acid and lignin free solid core barrier board to construct our phase boxes.  Our PVA adhesive meets library binding standards for long term stability. The tight fit of the phase box helps protect items from exposure to light and harmful pollutants.

Grey/White Board

The solid-core grey/white board used in our phase box product is made from non-groundwood pulp. It is lignin-free with an 8.5 pH and 3% calcium carbonate reserve. It has passed the Image Permanence Institute’s Photographic Activity Test (PAT), (ISO Standard 18916), and is safe to use with photographic albums.

For an additional cost, acrylic coated grey/white board is also available.

Tan Board

The solid-core tan board used in our Phase Box product is made from fully bleached virgin kraft pulp. It is lignin-free with an 8.5 pH and 3% calcium carbonate reserve. It has passed the Image Permanence Institute’s Photographic Activity Test (PAT), (ISO Standard 18916), and is safe to use with photographic albums. Colorfast and fade-resistant pigments give this board its color.
