What is an acid-free box or folder?

Acid-free folders and boxes are storage products intended for long-term storage of books and documents, dedicated to the sector of archiving. They are made of specialist, certified acid-free paperboard and cardboard. This means that their pH value – unlike that of most kinds of ordinary board - is higher than 7.5. Thanks to that, they do not accelerate the degradation process of the archived records and ensure optimal environment for their long-term storage.
