Common questions
What is ECT-32 and how does it impact stacking capacity?
ECT (Edge Crush Test) of 32 lbs/in measures the box's vertical load strength. ECT-32 safely handles 4-5 box stacks in typical warehouse conditions, ideal for mid-weight products up to 30 lbs per box while maintaining compliance with freight carrier stacking standards.
How much storage space do flat-packed boxes save compared to pre-assembled?
Flat-packed corrugated boxes reduce storage footprint by approximately 60-70% and lower inbound freight costs by 45-50%. A standard pallet of 1,000 flat boxes occupies the space equivalent of only 150-200 assembled boxes, directly improving warehouse productivity.
Are these boxes suitable for food-grade shipping?
Yes. Our 42x11x6" kraft corrugated boxes meet FDA food-contact standards and are ideal for bakery items, frozen foods, restaurant supplies, and catering distribution. Kraft material provides natural moisture resistance without chemical coatings.
What dimensions and weight limits should I consider for freight optimization?
At 42" length, these boxes optimize standard pallet layouts (two boxes per row = 84" across a 40" pallet with minimal overhang). Recommended product weight: 15-30 lbs per box to balance protection, stacking stability, and carrier freight classification savings.
