Rag mat
board
"Rag"
is a papermaker's term dating back to the 15th century when cotton
rags and trimmings were the principal raw materials used for papermaking.
The term continues to be used to describe papers and boards made
of 100% cotton fibre pulp.
Regular
mat board
This is made from
wood pulp, which is buffered (pH balanced) during manufacture.
The core and back of the board are acid-free, but not the surface
paper. Rag mat board is made from cotton. The core, backing and
surface paper are acid-free. Rag mat boards come in 2 thickness
- 2 ply and 4 ply. 4 ply is roughly the same thickness as regular
mat board.
