Unlike plain folding cartons, corrugated shipping boxes are built with a fluted inner layer sandwiched between two flat linerboards, creating a structure that absorbs impact and resists compression. This makes them the default packaging choice across parcel logistics, e-commerce fulfilment, and general freight. Flute selection matters: single-flute grades such as A or C handle lighter goods, while double-flute combinations like BC are specified for heavier or stackable shipments. Linerboard grade further determines performance — kraft liner outperforms test liner in burst and edge-crush tests. Corrugated boxes should not be confused with solid fibreboard cartons, which lack the fluted core and serve different load profiles.
