What are the features or advantages of Cleaner’s Supply’s acid free tissue (TU3)?

Our acid free tissue is unbuffered and is recommended for storage purposes. It has a pH level of approximately 7. Unlike buffered tissue, this has no alkaline buffer added to it. Alkaline buffers, such as calcium carbonate, are intended to neutralize acidic build-up in the future. Unbuffered tissue is recommended for silks, wool, or other unknown materials because some of the protein fibers in the materials may be sensitive to the alkaline buffers.
