Container compression test

The box compression test specifies the strength which can take up a packaging without bending.

The BCT value is a measure of the stability of a packaging and is specified in kN (Kilonewton). This value is depending on the air humidity or the moisture of the folding box as well as from the material construction (cardboard, paperboard, corrugated board; single- or multilayer; craftliner, testliner, fluting, fiber length, etc.). By using the ECT value one can calculate with the so-called McKee-formula the BCT value approximately. Using the McKee-formular it is the easiest way to calculat the BCT value, but also unmost exact. In practice the BCT value is determined with the help of a compression press.
