Here are some key characteristics of archival paper:
- Acid-free: Archival paper is free from acids, which can cause paper to become brittle and deteriorate over time. Acid-free paper is made using alkaline buffers, which help to neutralize acids and protect the paper from damage.
- Lignin-free: Lignin is a natural compound found in wood pulp that can cause paper to become yellow and brittle over time. Archival paper is made from lignin-free pulp, which helps to prevent this from happening.
- High-quality fibers: Archival paper is made from high-quality cellulose fibers, which are strong and durable. These fibers help to ensure that the paper will last for many years.
- Buffering: Archival paper is often buffered with alkaline materials, such as calcium carbonate, to help neutralize acids and protect the paper from damage.
- Durability: Archival paper is designed to be durable and long-lasting. It can withstand frequent handling and is resistant to tearing and fading.
Archival paper is commonly used for important documents, such as legal contracts, certificates, and historical records. It is also used for artwork, photographs, and other valuable items that need to be preserved for future generations.
It's important to note that archival paper is different from regular printing paper, which is not designed for long-term preservation. Regular printing paper is typically made from wood pulp and contains acids and lignin, which can cause the paper to deteriorate over time.
