Edge Crush Test
The Edge Crush Test (ECT) The Edge Crush Test, or ECT, is a newer test developed to look specifically at how much force a corrugated material can withstand on its edges without crushing. Instead of applying force to the face of the corrugated material, as the Mullen Burst Test does, ECT applies force to the edge.
What does 200lb test mean?
bursting strength
200 lb. test refers to bursting strength, while 32 ECT refers to stacking strength. Boxes that meet 200 lb. test boxes are made with heavier paper and have 50% greater bursting strength than 32 ECT boxes. Greater bursting strength means fewer crushed and damaged boxes during shipping.
What is something stronger than cardboard?
A team of engineers from the University of Pennsylvania has created a new material called nanocardboard that is the ultrathin equivalent of corrugated paper cardboard.
