If your primary concern is crushed boxes nd stacking problems, consider specifying in terms of ECT. If it's a containment strength .Through certain testing methods such as the Edge Crush Test (ECT) and the Burst Strength Test, also known as the Mullen Burst Test, it is possible for companies to foresee these contingencies and design protective packaging according to their needs. In this context, it is common to face the dilemma between Edge Crush Test vs. Burst Strength.
Although both the Mullen Burst Test and the Edge Crush Test, which are of great significance in gauging the strength of corrugated materials, they do not measure the same properties. The ECT determines a material’s resistance to edge or edgewise compression, which is vital in determining how well boxes can endure stacking and shipping pressures. ECT is often looked at by customers who are concerned about the max weight a box can stand during pallet shipments or warehouse stacking. The most common and universal boxes used today are 32 ECT. The Mullen Test measures the bursting strength or the force required to burst a hole through the corrugated material. This measurement is calculated . The Edge Crush Test, which was developed in the 1990’s, measures the stacking strength of corrugated board – how much top to bottom pressure a box can withstand before crushing. Boxes conforming to the Edge Crush Test standard are identified as 32ECT, 44 ECT, etc. Again, the higher the number, the stronger the corrugated box.
