Why Acid-Free Storage Matters
Time does not forgive improper storage
Every collection tells a story, but improper storage can silently rewrite it. Ordinary cardboard boxes and envelopes slowly damage the very things they are meant to protect.
Improper storage Ordinary cardboard
Acid discoloration
Acidic cardboard and paper cause yellowing, browning and brittleness.
UV degradation & colour bleed
Light exposure fades photographs and inks and makes colours bleed.
Physical warping
Poorly supported material bends, warps and cockles over time.
Acid migration stains
Acids transfer from ordinary storage materials onto the objects they touch.
Corrosion
Metal objects such as coins and medals corrode in unstable storage.
Properly stored Acid-free archival box
Alkaline buffer
Formulated to counteract acidic compounds and slow deterioration.
Lignin-free
Excludes lignin, the wood component that causes discoloration and brittleness.
Non-volatile
Made from materials that do not emit harmful gasses over time.
Moisture buffer
Helps maintain a stable, safe internal climate around the contents.
Light protection
Closed archival enclosures shield contents from damaging UV light.
Protect what matters. Choose acid-free archival boxes.
