FCT (Flat Crush Test) is a test method by which one evaluates the behaviour of cardboard and pasteboard packaging materials under pressure applied to a flat surface. The test machine starts applying pressure on the flat surface of the sample. The pressure starts slowly crushing the sample. The results are reported usually as a value expressing the crush resistance per unit. This information is used to understand the strength and integrity of the packaging when the products are piled or stowed. This is important to evaluate the performance of packaging during transportation or storage.
