From Wikipedia:
Acid-free paper is paper that has a neutral or basic pH (7 or slightly greater). It can be made from any cellulose fiber as long as the active acid pulp is eliminated during processing. It is also lignin and sulfur free. Acid-free paper addresses the problem of preserving documents for long periods.
