Stacking crush resistance

The stack compression resistance ( BCT value from English box compression test ) indicates the force that a package can absorb and remove without buckling.

The BCT value is therefore a measure of the stability of packaging and is given in kN (kilonewtons). This value depends on the humidity or the intrinsic moisture content of the folded box as well as on the material structure (cardboard, solid board , corrugated cardboard, single or multiwall / -lagig; kraftliner , testliner , fluting, fiber length, etc.). The BCT value can approximately be calculated using the edge crush resistance (ECT value) using the McKee formula. The McKee formula is the simplest for calculating the BCT value, but it is also the least precise. In practice, the BCT value is determined with the help of a stacking press .
