pulpboard
A type of BINDER'S
BOARD produced either in a single web, a

machine, that is, a twin-wire board. Pulpboard
quality depends on the furnish used, which may be
mechanical or chemical wood pulp, or a combination
thereof. It differs fromPASTEBOARD in that
the pulpboard is made directly from the pulp,
whereas pasteboard is built up from thinner sheets
of paper or board laminated together. Pulpboard is
the principal board used in library and edition
