Common questions
What is the stacking weight capacity for ECT-44 corrugated?
ECT-44 single-wall corrugated supports approximately 25-35 lbs per box in a 3-tier warehouse stack, depending on contents and storage conditions. Contact our packaging engineers for custom load-bearing calculations based on your specific application.
Why choose side-loading over top-loading boxes for these dimensions?
Side-loading eliminates the need to slide long items through narrow top openings, reducing handling time by 40% and minimizing edge crushing damage. This design is ideal for rigid or fragile elongated products that are difficult to insert vertically.
Can these boxes be customized with printing or branding?
Yes. Kraft corrugated accepts full-color flexographic and digital printing. Minimum order quantities apply, contact our sales team for custom branding options and pricing on volumes above 5,000 units.
How does flat-pack shipping reduce my total packaging costs?
Flat-packed boxes reduce inbound freight costs by 75-80%, lower storage footprint in your warehouse, and eliminate assembly labor. A bundle of 10 flat boxes occupies roughly 2 cubic feet versus 18+ cubic feet assembled, delivering measurable ROI on volume orders.
