What is Acid Free and Buffered Paper?
Understanding the difference between acid-free and buffered paper is essential for preserving photographs, documents, and artwork. This video explains these archival materials, their benefits, and when to use each for long-term storage and protection. What is Acid-Free Paper? Made without acidic components that cause the paper to turn yellow and deteriorate over time. pH level is neutral (7.0 or higher), ensuring longevity and preventing damage to stored materials. Ideal for storing photographs, documents, artwork, and prints that require long-term preservation. What is Buffered Paper? Includes an alkaline reserve (typically calcium carbonate) to neutralize acids that develop over time. It helps protect against acid migration from surrounding materials or environmental pollutants. Recommended for storing paper-based documents, books, and artwork that benefit from pH stabilization. When to Use Each? Acid-Free Unbuffered Paper: • Best for cyanotype photographs, silk, wool, and protein-based materials. Acid-Free Buffered Paper: • Suitable for paper-based materials, such as historical documents, letters, and artwork, as it helps prevent acid buildup. • Recommended for long-term document storage where acidity may develop over time. • Ideal for black-and-white and color prints and inkjet prints.
