Common questions
What does ECT-32 mean and why does it matter for my warehouse?
ECT-32 (Edge Crush Test) means the corrugated material resists 32 lbs of force per linear inch. This rating ensures reliable stacking performance in multi-tier warehouse storage and protects goods during handling and transit without requiring double-walling, lowering your packaging costs.
How much can I stack these boxes, and what's the weight limit?
ECT-32 single-wall corrugated typically supports 4 - 6 boxes high when fully loaded, depending on total box weight and warehouse conditions. For specific stacking calculations, consult our packaging engineers or test with your typical product weight.
Why choose long-side opening boxes for long products?
Long-side openings align with your product orientation, eliminating awkward packing angles and reducing labor time per box. This design also improves ergonomics for your team and reduces damage risk from improper item placement.
Are these boxes eco-friendly and recyclable?
Yes. These kraft corrugated boxes are 100% recyclable and made from renewable materials. They support your sustainability commitments while meeting B2B shipping standards and reducing your environmental footprint.
