Acid-free paper is a type of paper made with a neutral pH level, typically between 7 and 8. This means that the paper is neither acidic nor alkaline, making it resistant to deterioration over time. Traditional paper contains lignin, a substance that breaks down as it ages, causing the paper to become yellow, brittle, and fragile. Acid-free paper, however, is lignin-free, ensuring longevity and durability.
The acid-free properties of this paper make it an ideal choice for preserving important documents, such as legal records, historical archives, and photographs. By using acid-free paper, you can protect these valuable materials from the detrimental effects of acidity and ensure their long-term survival.
