Foam Core - Is a type of board that is comprised of a solid paper surface with an inner polystyrene core.

Card Board - Is a type of board that is comprised of paper surface reinforced with a meshed paper design.

I've stated weak or sturdy for cardboard because the majority of cardboard that is used to package items will collapse along it's grain.  There are some cardboards that are really rigid but are only seen on large items and products of great value.
