Common questions
What weight can these boxes safely hold?
ECT-32 single-wall construction safely handles products up to approximately 35 lbs, depending on internal packing method and stacking height. For heavier items or multi-box stacking scenarios, consider ECT-44 double-wall boxes.
How does ECT-32 compare to other corrugated grades?
ECT-32 delivers standard industrial performance for typical B2B shipments and e-commerce orders. It's lighter and more economical than ECT-44 (double-wall) but rated higher than ECT-26, making it the efficiency sweet spot for mid-weight applications.
What's the pallet stacking advantage of the 12129 size?
This compact footprint fits up to 48 assembled boxes per pallet layer, maximizing your pallet utilization while staying within standard 4840" dimensions. You'll reduce freight cost per unit shipped and lower your storage footprint.
Are these boxes recyclable and sustainable?
Yes. 100% recyclable kraft corrugated material supports corporate sustainability initiatives and appeals to eco-conscious customers. No plastic, no coatings, pure cardboard ready for standard curbside or commercial recycling programs.
