Volatile organic acids

Much research has been done about emission of volatile acids from
wood products used in display-cases. However, a large quantity of
objects aren't stored in display cases but in cardboard boxes. In
museum practice, for these cardboard boxes practically all types of
paper products are used, from corrugated board to buffered acid free
pure cellulose board. There is general agreement that paper material
used in direct contact with art objects should be non-acid, but I
ignore any research about acid vapours in cardboard boxes. Can boxes
out of corrugated board be supposed to contain much higher amounts
of acid vapours than buffered board, or would it be sufficient to
use lignin-free cardboard? Has there been any serious research on
this matter? Any comments are welcome.
