The preferred choice for books, maps and documents, alkaline paper is usually used where aging resistance is preferred.
Non-acid paper that has a high degree of permenance.
Paper using calcium carbonate as the filler and a synthetic material, compatible with the alkaline process, as a sizing agent. This process increases the longevity, bulk brightness, opacity and printing characteristics of the paper without added cost.
Paper formed in an acid-free process; long lasting, does not yellow with age. Because of environmental concerns, many papers are now alkaline based.
Permanent paper (PH 7.5 to 8.2)
Paper made with a synthetic alkaline size, and alkaline filler like calcium carbonate, which gives the paper over four times the life (200 years) of acid-sized papers (40-50 years).
A paper made with synthetic alkaline sizing and an alkaline filler such as calcium carbonate which gives the paper more than four times the life (more than 200 years) of acid-sized papers.
Permanent papers (PH of 7.5 - 8.2).
Paper manufactured under alkaline conditions (acid free), using additives, caustic fillers like calcium carbonate and neutral size. The anti-aging properties in alkaline paper make it a logical choice for documents where permanence is essential.
