Morphology

corrugated + cardboard

The meaning 'stiff, strong cardboard with fluted ridges' is directly and transparently derived from combining 'corrugated' (textured with parallel ridges) with 'cardboard' (stiff paper material). This adjective+noun composition follows standard English modification patterns and is cross-linguistically common, so a B1 learner who knows both constituents will readily understand the MWE.

Etymology

Corrugated cardboard comes from how it is made: corrugated means a wavy middle layer and cardboard is the flat paper on each side, so the material is like a paper 'sandwich' with waves inside. Those waves make the board stiff and create small air pockets that absorb knocks, so the material is 'strong' and 'protects' items in boxes.
