Types of Corrugated Boxes & SheetsBurst Strength vs. Edge Crush Test

Burst Strength

The force required to rupture combined board, using vacuum pressure measured by a Mullen tester, relates indirectly to the box’s ability to withstand external or internal forces. The results of the test indicate the box's ability to contain and protect its contents during rough handling.

200 lb. Test Mullen - what does that mean?

Burst Strength of 200 lb. test material means it will withstand 200 pounds of pressure per square inch as measured by the Mullen tester.ECT Edge Crush Test - the amount of force needed to crush an on-edge specimen of combined board is a primary factor in predicting the compression strength of the completed box. In most instances, stacking strength, not bursting strength, is critical to box performance.
