Looking at the pictures, that's what I'd call them.

'Timber packs' gets a reasonable number of Ghits and the photos show much the same type of bundle.

"All sections are available in full sized imported packs (about 4m3) or in smaller, loose metre runs as required. " quote from http://www.snowstimber.com/joinery-quality-softwood/

"Visitors to the iWood website are now able to buy bundles of pre-cut timber - known as 'Packs' - available in the leading species such as European Oak, American Cherry, Sycamore and European Beech."

One New Zealand website referred to timber packets but that term seems to be limited to that country.

We used to call them bundles at the sawmill I worked in. They are the flat sawn (i.e. plain sawn, as opposed to quarter sawn or rift sawn) boards (flitches) from a log, stacked in the order they were positioned in the log before sawing, with spacers between them to allow drying, and bundled with steel ties.

can't find anything shorter

constructing the log model. - The central axis of each log in
the sample is located by marking the center of both ends of the log
(fig. I) Boards are then sawed parallel to the Y axis. Using the central
axis as a reference, each board surface is identified by the Z-axis location
it held before sawing. Similarly, the board width is identified by Y-axis
values and the board length by X-axis values.
Defects in each board are grouped into classes that depend upon the
products being considered. Each class includes those defects that would
cause rejection of the piece for a particular use. For examp!e, if the yield
of parts for pallets, flooring, or dimension stock is to be determined, then
three classes of defects can be used. When the yield of pallet parts is being
computed, program DEFECT will ignore the flooring and dimension
classes of defects.
Program DEFECT provides for reassembly of the boards into their
original log form. Because board outline and defect location have been
converted to numerical data, they are "visible" to the computer; therefore,
the reassembled log can be considered a "glass log."
