Common questions
What is ECT-32 and why does it matter for my shipping needs?
ECT-32 (Edge Crush Test 32 lbs/inch) is the industry standard for single-wall corrugated. It provides reliable stacking strength for typical warehouse environments, handling multiple boxes stacked during storage and transit without compression failure, reducing damage claims and customer returns.
How many boxes fit on a standard pallet with this 30x12x4 size?
A standard 48 x 40" pallet typically accommodates 40-50 assembled boxes per layer (3-4 layers high = 120-200 boxes per pallet). Flat bundles of 25 maximize pallet utilization with minimal vertical space, enabling higher inventory density and faster order fulfillment cycles.
Can I mix these boxes with my existing automation equipment?
Yes. The 30 x 12 x 4" dimensions are compatible with standard box erecting, taping, and labeling equipment used in most mid-size fulfillment centers. Confirm your equipment's maximum box length specification (30 inches).
Are these boxes environmentally compliant and recyclable?
Fully recyclable Kraft corrugated meets EPA and industry standards for sustainable packaging. 100% post-consumer fiber content available; confirm with your Packrift account manager for certified eco-friendly options.
