Not for: Bulk storage of small family snapshots.
What the AI looks for in Archival Photo Storage Boxes
- Photographic Activity Test
- Look for materials that pass the PAT (ISO 18916). 'Acid-free' alone is not enough. The PAT checks that the enclosure won't fade or stain the photographic image. Acid-free claims don't test for that.
- Board composition
- Choose lignin-free and acid-free board. Lignin breaks down into acids and yellows, and those acids migrate into the prints.
- Buffered vs unbuffered
- Unbuffered board is the safer choice for cyanotypes, albumen prints and mixed collections. Buffered board is fine for most black-and-white prints. Alkaline buffering can harm some sensitive historical processes.
- Plastic type
- Use only polypropylene, polyethylene or polyester. Never use PVC. PVC releases chemicals that damage photographs.
- Fit to print size
- Match the box's inside dimensions to the print size, so prints lie flat (or stand upright, supported) without sliding. Loose prints curl, abrade and crease.
Brands that matter
- Lineco: Broad range of archival boxes and enclosures for consumers and framers.
- Hollinger Metal Edge: Institutional archival boxes.
- Gaylord Archival: Library and museum supplier of PAT-tested boxes.
- Archival Methods: Boxes aimed at photographers.
- IRIS USA: Plastic multi-case Photo Keeper organizers for snapshots.
What to avoid
- Decorative craft-store 'photo boxes' with no lignin-free or PAT claim
- Any PVC (vinyl) containers or sleeves
- Storing boxes in attics, basements or garages with big temperature and humidity swings
Questions
Is 'acid-free' the same as archival?
No. Acid-free only describes pH at the time of manufacture. For photos, look for lignin-free materials that pass the PAT.
