Common questions
What does ECT-48 rating mean for my warehouse operations?
ECT (Edge Crush Test) 48 lbs/inch means each box withstands 48 pounds of crushing force per linear inch of flap. For 40" dimension, this translates to 1,920 lbs total crush strength, ideal for 4 - 5 tier stacking in warehouse racks without dimensional collapse or product damage.
How much freight cost can I save with flat-shipped inventory?
Flat-shipped boxes reduce inbound cube by 85 - 90% versus pre-assembled cartons. A pallet of 50 bundles (500 boxes flat) occupies 12 cubic feet; assembled, that same quantity requires 85+ cubic feet, translating to 40 - 60% LTL freight savings per order.
Are these boxes compatible with automated packing lines?
Yes. Double wall construction and pre-scored flaps integrate directly with pneumatic case erectors and semi-automatic packing equipment running 20 - 50+ boxes per minute. ECT-48 rigidity prevents jams and deformation in high-speed operations.
What's the difference between double wall and single wall for my use case?
Double wall delivers 2 - 3x greater crush strength, puncture resistance, and stacking capacity than single wall. For heavy industrial goods, multi-tier storage, or long-distance shipping, double wall (ECT-48) reduces damage claims and warehouse rework by 35 - 50%, offsetting modest price premium.
