glassine paper
A supercalendered paper manufactured principally
from chemical wood pulps which have been beaten to
secure a high degree of stock hydration. Glassine
paper is grease resistant, has a high resistance
to the passage of air, and is almost impervious to
the passage of water vapor. It is also smooth and
transparent, or semi-transparent. It is made in
white and various colors, and may also be made
opaque by the addition of fillers. Basis weights
range from 12 to 90 pounds (24 X 36�),
with the ordinary range being from 15 to 40
pounds. Glassine tape, which is the paper backed,
with a water-soluble adhesive, is sometimes used
to repair torn book leaves, although it will
eventually turn yellow and may damage the paper.
It is also used in lieu of cellulose acetate in
theSUNDEX PROCESS
of lamination. (17 ,
