The principal raw materials going into the pro-
duction of paperboard are Southern kraft (for cor-
rugated Containers) and high grade reclaimed paper,
or "paper stock" as the trade refers to it. Naturally
there are many other additives such as sizing, clay
coating, wet strength chemicals, dyes and, of course,
printing ink.
Until recent years, most kraft came from Scandi-
navia but today practically all of it comes from a string
of modern mills scattercd over the South and West
Coast, many of them costing more than ten million
collecting and sorting agencies. The degree to which
this sorting is carried out is illustrated by the fact that
during the war the OPA listed ceiling prices and
definitions for 32 different grades of paperstock.
EARLY DEVELOPMENT
The history of paperboard is a venerable one even
though its great growth has been in the past half
Century. The earliest books, hundreds of years ago,
were bound in thick Covers made by pasting many
sheets of paper together by hand hence the term
"pasteboard." (These are now made in one Operation
on a "wet machine" and are referred to as "binders
board"). But for the next few centuries growth was
very slow. The big impetus which came about fifty
years ago was probably due to the phenomenon of

dollars exclusive of attendant woodlands. At any
given moment there are several new mills under
construction in these areas and others are in the
planning stage.
RECLAIMED PAPER
Paper stock comes primarily from metropolitan
waste paper collection. Tremendous sorting rooms
divide the mixture into different grades which are
compressed into large bales and sold to the paper
board mills. Some of these mills operate their own

package merchandising. Smaller homes and fam-
ihes, national advertising and the desire for sanitary,
branded products have put nearly all of our neces-
sities into packages, many made of paperboard.
These, in turn, are shippcd in fibre Containers rather
than in heavy wooden boxes and barreis.
Then came the super-market era with 110 clerk to
push one brand over another. Fhis provided a ficld
day for the folding box and other types of shelf
packages and the paperboard industry was quick to
realize the implications. The package had to seil itself
and this has been accomplished by a beautiful ex-
