cellulose film
A transparent film produced from cellulose fibers
by a process that involves steeping, shredding,
and converting the fibers into a viscose solution,
or cellulose xanthate, which is subsequently
extruded to convert it into a film. It is made in
a limited range of thicknesses, between 0.00085
and 0.0016 inch, and, when rendered moisture
resistant, may be used to seal documents, book
leaves, etc., for protection. It is a fairly
flexible film of considerable strength. (81 )
