These tend to provide better protection against damage from external forces (such as dropping, kicking or punctures) than boxes with an equivalent ECT rating. A box with a Mullen Test rating of 200# is equivalent to 32 ECT in terms of stacking strength, but will have a bursting strength about 60% greater than the ECT box. This will not matter if your primary concern is stacking and palletizing, but can

This will help you create a stable base with a lower center of gravity. It also helps you avoid crushing any lighter, less-dense goods. Tip 2: Up to the edge, not over. For maximum stability and pallet density, arrange your boxes in a way that brings them as close to the edges of your pallet as possible without hanging over. Bringing your boxes to the edge makes strapping goods down easier and more stable. It also ensures you’re using as much pallet
