board is made largely of recycled paper and most
commonly comprises three components: an outer and
inner “liner”, (the flat, surface components), and
a “corrugating medium”, the “fluting”, which is
glued between the liners It is this sandwich-type
construction that gives corrugated board its excellent
rigidity and structural strength as well as its
unique cushioning characteristics.
Over the decades,
corrugated board has evolved and developed to provide
a wide range of products for different applications.
Standard and non-standard categories of corrugated
board are based on the type of flute, whether coarse,
fine or extra fine and the number of fluted walls
whether single, double or triple layered.
For the purpose
of 3-D modeling, options include
single wall – and double
wall corrugated board, each of which can be made
in a variety of weights and thicknesses.
The standard range
includes the coarse ‘A’ and ‘C’ flute, fine ‘B’
and extra fine ‘E’ and ‘F’ flutes. The ‘B’ flute
is the most widely used. It is very robust (difficult
to crush) and has good compression strength. The
‘C’ flute is larger with greater compression strength
but offers less crush resistance and requires more
face corrugated board
is manufactured in standard widths ranging from
56” to 36”. It is easily transported in rolls.
Its ability to withstand compression (an important
factor for the stability of a 3-D model) is determined
by the quality and thickness of the liner and the
corrugating medium. For 3-D modeling, the liner
and the corrugating medium should be at least 185
g/m2 and 150 g/m2 respectively.
The best solution is to request a specially manufactured
corrugated board making use of a liner (175 - 185
g/m2) and a kraft liner (175 –185 g/m2).
of corrugated board (an important dimension in respect
of scaling 3-D models) is conventionally measured
as detailed in the Table below.
If transport is
not a constraint, you may wish to consider procuring
single or double wall corrugated board, making sure
that you get the best possible quality in terms
of strengths as discussed above.
Provided you order
a minimum quantity, depending on the goodwill of
the manufacturer, corrugated board sheets can be
cut to the desired size ahead of the modeling exercise.
In this case,
the size of the board should possibly match that
of the base table and the base map.
and double-wall corrugated boards are classified
as detailed in the Table below and offer additional
resistance to compression.
The choice between
the various media will depend on their availability
or readiness of manufacturers to produce them according
to the desired specifications and to the transport
facilities available to you to haul the material
to where the model will be assembled. Rolls of board
are easier to transport, as they can easily fit
into the back of a pick up. Large carton board sheets
are necessarily placed on the roof of a vehicle
or in a truck you may want to get for the purpose.
