Acid Free Tissue Paper

Q: What is the difference between acid-free and acid-free buffered tissue paper used in packaging wedding gowns?

A: Acid-free is a general term for a tissue paper that is free of acid or has a pH of approximately 7. Textile conservators recommend that this be used for silk and wool fabrics or whenever the fiber content is mixed or unknown.

Acid-free buffered tissue paper has an alkaline buffer such as calcium carbonate that helps neutralize any acids and retards the evolution of acid in the future. Conservators recommend this type of tissue paper for storing cellulose fabrics such as cotton, linen, and, ramie to protect them from deteriorating.

Unbuffered tissue should be used when storing silk or wool because protein fibers are known to be sensitive to alkalis.
