Container compression test

The stacking strength ( BCT value - Box compression test) indicates the force that can take up and pay off a package without kinking.

The BCT- value is a measure for the stability of a package and is specified in kN (kilo Newton ). This value depends on the humidity or inherent moisture of the carton and on the material structure ( board, solid board, corrugated board, one or more wavy / -ply, kraft liner, test liner, fluting, fiber length, etc.). You can About the ECT value is approximately the McKee formula calculate the BCT value. To calculate the BCT value, the formula is easiest according to McKee, but also the least accurate. In practice, the BCT value is determined using a batch sizing press.
