Overview[ edit ] Paper made from wood-based pulp that has not had its lignin removed turns yellow, becomes brittle, and deteriorates over time. During production, acid-free paper may be treated with a mild base usually calcium or magnesium bicarbonate to neutralize the natural acids occurring in wood pulpand it may also be buffered to prevent the formation of additional acids as may develop from the application of sizing. The bicarbonate is added in excess, to supply the paper with an alkaline reserve to provide protection from further attack by acids remaining in the paper or supplied by the environment e. PCC reacts with acids, and therefore requires the pulp to be chemically neutral or alkaline.
Which is Best for Your Collection? Please Note - We now sell our Acid Free Tissue Paper under our other seller name - AcidFreeTissuePaper After visiting many different websites that sell buffered and nonbuffered Acid Free tissue, I found so much conflicting information, and sometimes totally inaccurate information, that I went straight to the historic conservation experts.
Acid Free means that the tissue is free of acids that will cause it to deteriorate over time and damage the other items that it touches.
Our Acid free tissue is archival quality and is NOT the same as gift grade tissue paper or packing tissue paper. The buffering counteracts the effects within the material or in the environment, providing long term protection.
Unbuffered or Nonbuffered lacks the buffering reserve to prevent future acidity. It is used with materials that are sensitive to a higher pH level. The scale ranges fromwith 7 being neutral. Do NOT use colored tissue as the dye can bleed onto and ruin your collections!
Pests - Many collections, as well as the tissue paper itself, can attract moths, silverfish and other little pests which love to feast on your prized collections!
For years I have stored my own personal collections with high quality French Provence lavender sachets, which not only smell heavenly, but as an added bonus they are safe and natural insect repellents.
An occasional squeeze will renew the fragrance, and they last for years! Even living in Florida, I have never once had a problem with these little uninvited pests.Target Cartwheel, a whole new spin on coupons.
