Q: What makes an archive box good for long term storage?
A: Archival quality boxes are made from materials that are free from lignin and acid, which helps to keep items safe for a long time. These boxes are best to store like artwork, photos, important papers, and other valuable items. They are designed to stay pH-neutral, and sometimes buffering agents like calcium carbonate are added to prevent damage from acidity. Sturdy construction with reinforced corners and strong board materials also provides extra protection against outside elements.
