onion skin
A durable lightweight paper that is thin and
usually nearly transparent—so called because
of its resemblance to the dry outer skin of an
onion. It is used for making duplicate copies of
typewritten material, permanent records where low
bulk is important, and for airmail correspondence.
It is produced entirely from cotton fibers,
bleached chemical wood pulps, or combinations of
these. The fibers of the paper are long and the
paper is sized with rosin, starch or glue; it is
usually supercalendered or plated to a high
finish, or is given a cockle finish. Basis weights
range from 7 to 10 pounds (17 x 22). See
