Common questions
What ECT rating does this box have and what does that mean for my products?
ECT-32 (Edge Crush Test 32 lbs/in) single-wall corrugated provides reliable stacking and compression strength for shipments up to 2-3 units high on standard pallets. This rating handles typical e-commerce parcels and light-to-medium density items; heavier products may require ECT-44 or double-wall alternatives.
How many boxes fit on a pallet, and what's the freight efficiency?
A standard pallet accommodates approximately 1,200-1,400 assembled 4x4x4" boxes depending on stacking height. The compact cube geometry maximizes utilization and reduces LTL dimensional surcharges compared to rectangular boxes, improving your per-unit freight economics.
Can these boxes handle oddly shaped products or fragile items?
Yes, the cube design accommodates cylindrical, round, and irregular shapes effectively. For fragile items, pair these boxes with void-fill materials like crinkle paper or air pillows; ECT-32 alone provides structural support but not shock absorption.
Are these boxes compostable or recyclable in standard programs?
Kraft corrugated is 100% recyclable through standard curbside and industrial recycling programs. The boxes contain no plastic or coatings, making them ideal for sustainability-conscious shippers and supporting your circular economy commitments.
