Common questions
What does ECT-32 mean and how does it compare to other ratings?
ECT (Edge Crush Test) 32 means the box withstands 32 lbs of force per linear inch before crushing. This is the industry standard for single-wall corrugated; it's suitable for most B2B shipping but lighter than ECT-44 double-wall alternatives used for heavy or fragile items.
How much warehouse space do flat-packed boxes save versus pre-assembled?
Flat-packed corrugated boxes occupy approximately 80% less cube space than pre-assembled boxes, translating to significant storage savings for high-volume operations. A pallet of 900 flat boxes typically occupies 4-5 linear feet of racking versus 15+ feet for the same quantity pre-assembled.
Is this box size optimized for standard pallet configurations?
Yes. The 28 x 18" footprint is designed for 40 x 48" standard pallet compatibility, allowing 10-12 boxes per layer with minimal overhang. This maximizes stacking density and reduces freight spend per unit shipped.
Can these boxes handle multi-zone shipping in temperature-variable environments?
ECT-32 kraft corrugated performs reliably across standard indoor warehouse conditions (55-75°F, 35-65% RH). For temperature-sensitive items or outdoor storage, we recommend ECT-44 double-wall or specialty moisture-barrier options.
