This .001 thick (16 gm2) acid-free tissue paper has a 3% calcium carbonate buffer added. Buffering agent will help prevent acid migration to the tissue itself and is perfect for storing photographs and clothing sensitive to a higher pH level. Just cut and layer between your photos or digital images to protect them from acid migration and abrasion.
Made from acid-free, buffered tissue with a smooth surface for superior protection
250 foot roll
Note: Unbuffered tissue is pH neutral, and works well for storing most items including photographs and documents. Buffered tissue has an alkaline composition achieved by adding calcium carbonate. Buffered tissue will also work for photos but if you are preserving textiles, it is better to use buffered tissue for natural plant derived fibers and un-buffered tissue for animal fibers.
