Heavy-duty corrugated boxes
Double-wall and higher ECT options for heavier SKUs.
Overview
Stack and crush first.
Heavy-duty corrugated is for weight, stacking, and longer supply chains. Longae helps specify wall construction and board grade against your load and drop profile, then coordinates sampling and production partners. Not every SKU needs BC—we size strength to the job.

Quick answers
Do I always need double-wall?
No—only when weight and stack justify it. We propose the lightest board that meets the brief.
Can you print on heavy board?
Yes, within method limits; graphics quality varies by flute and press.
Export flat-pack?
Yes—KD packs are standard; note assembly if needed.
