Corrugated Crush Tester - Paperboard Test Machine Manufacture

CCT – Corrugated Crush Test. A sample is corrugated between heated corrugating rolls. The sample is fixed in a special jig that is adapted to the corrugated shape. The crushing force is applied and measured parallel to the top of the corrugating medium. The CCT value is the maximal force that the sample can withstand before it breaks.

Corrugated fiberboard - Wikipedia

Corrugated fiberboard is a material consisting of a fluted corrugated sheet and one or two flat linerboards. It is made on "flute lamination machines" or "corrugators" and is used in the manufacture of shipping containers and corrugated boxes.. The corrugated medium sheet and the linerboard(s) are made of kraft containerboard, a paperboard material usually over 0.01 inches (0.25 mm) thick.
