Paper Longevity: Sleeves, Folders, and Climate
Acid-free, lignin-free sleeves and folders slow deterioration, while clear polypropylene protectors resist moisture without sticking to ink. Avoid direct sunlight and wide humidity swings; cool, dry, and dark wins. Flat storage prevents creases and tears, especially for older certificates. Use pencil or archival pens for labels, and never staple irreplaceable originals. Consider desiccant packs in sealed bins where humidity fluctuates. Tiny choices—like a softer clip or buffered paper—compound into decades of preservation, letting your records remain legible, intact, and ready for whatever bureaucracy requests next.
