kraft paper
A paper produced by a modified sulfate process,
and employing only wood pulp. It is a relatively
coarse paper and is known especially for its
strength. Kraft paper is usually manufactured on a
Fourdrinier machine and is generally given a
regular machine finished or machine-glazed
surface. It can be watermarked, striped, or
calendered, and has an acceptable surface for
printing. Its natural unbleached color is brown,
but it can be produced in lighter shades of brown,
cream tints, and white, by the use of
semi-bleached or fully bleached sulfate pulps.
Kraft paper is generally made in basis weights
from 25 to 60 pounds (24 X 36�) but it is
also made in weights ranging from 18 to 200
pounds. (17 , 1 , 323 )
