Pallets are often stacked with five layers of record boxes. The vendor who is doing the drying might specify another arrangement which could be accommodated. If some boxes are lighter or less than full, they should be on the top layer of the pallet. After a pallet is filled it should be surrounded by hand wrap, which is also known as stretch wrap. This is a thin but strong plastic film that is rolled around the pallet and its contents.
Hand wrap is a safeguard against shifting while the trailer is on the road.
