The blue/grey paper is acid-free and buffered with 3% calcium carbonate. Because it is moderately porous, it allows the frame package to breathe. It cuts cleanly and is easy to handle.

• Available in rolls: 12”x72”, 16”x72”, 20”x72” and 24”x72”
• Backing a frame with a paper barrier keeps out dust and other pollutants while allowing the artwork to breathe
• Archival quality frame backing paper avoids the possibility of acids leaching into the matting or artwork
