What’s the difference between BCT (Box Compression Test) and ECT (Edge Crush Test)?
Date: January 6, 2026Views: 2116
ECT measures the linerboard’s crushing strength perpendicular to the flutes (a material property). BCT measures the finished box’s overall stacking strength (a performance property). While related, BCT is the definitive test for predicting real-world warehouse performance. ECT is used in box strength estimation formulas like McKee.
