Common questions
What does ECT-32 mean and why does it matter for my operation?
ECT (Edge Crush Test) of 32 lbf/in indicates the corrugated can resist 32 pounds of force per linear inch, standard for single-wall boxes. This rating ensures reliable stacking performance in typical warehouse environments without over-specifying heavier (more expensive) ECT-44 material, directly improving your cost per unit shipped.
How many different box heights can I create from a single SKU?
The MD644 features multiple pre-scored fold lines in the side panels, allowing you to collapse the box to 2", 3", or 4" heights. This single SKU replaces the need to stock separate 6x4x2, 6x4x3, and 6x4x4 boxes, reducing your carton inventory by up to 66% while maintaining right-sized shipping.
Will these boxes work with my current carton sizer equipment?
No carton sizer is needed, the pre-scored construction allows manual folding to your desired height in seconds. This eliminates capital investment and labor time, particularly valuable for smaller facilities or operations with variable shipment sizes.
How do multi-depth boxes reduce my parcel shipping costs?
Parcel carriers charge based on the larger of actual weight or dimensional weight. By folding these boxes to the minimum height needed for your product, you reduce the dimensional weight calculation, often lowering per-package postage by 10-25% compared to oversized standard boxes.
