Heh! MDF does not have laminations, its compressed fibres.

MDF is pressed in sheets, rather than rolled. The pressure is applied in
one axis and so there are two strong tensile directions and one weak
one. You can (pointlessly) argue the semantics of "laminated" and
whether it means that such a material _must_ be formed by laminating
flat sheets together, but the simple upshot is that MDF has inbuilt
planes of weakness and disassembles into laminations, no matter how they
were formed.
