Weight Limits: For shipment that is not palletized end-to-end, each container should weigh less than 25 pounds, because boxes may be tossed about by shipping personnel. Heavier boxes are more likely to be damaged. 100 pieces of 6x8 (inches) per box are a good starting point.
There should be a minimum of 1½ inches of packaging material on EACH SIDE of the container. Full length and width of foam boards are preferred to cardboards. As cardboards are harder, they may damage the PCB's edge if the container is bumped against a hard object.
Packaging materials on sides must be overlapped to protect the PCB's corners.
The contents must be packed tightly as such that they will not shift. This is very important. Loosely packed shipment causes more content damage.
Below are some good visual examples:
