A note from Guardhouse:

Guardhouse backer boards are acid-free.

They are made from high-quality 24-point solid bleached sulfate (SBS) and are coated and buffered on one side with a 3% calcium carbonate buffer, which neutralizes acids and ensures the boards are pH neutral and safe for archival storage. This makes them suitable for long-term preservation of collectibles like comic books, preventing them from yellowing or degrading over time.

The boards are also independently lab tested and certified as acid-free to meet archival standards.
