Checklist
Product and distribution inputs to collect
- Flute and board build-up
- Protection requirement
- Distribution test
- Logistics volume
- Target quantity and SKU allocation
- Approval sample and decision owner
- Required date and Mainland China delivery point
- Change and repeat-order record
Structural decision
Four checks before freezing the structure
Flute and board build-up
Specify flute profile, liner combination, total thickness and direction; nominal flute letters alone do not define performance.
Protection requirement
Translate fragility, weight, edges, movement and distribution hazards into cushioning, retention and closure decisions.
Distribution test
Select drop height, orientation, sequence, packed weight and acceptance criteria from the real handling route.
Logistics volume
Calculate packed cubic volume and chargeable weight from the final carton plan, not from unpacked product dimensions.
Execution method
Four actions from RFQ to production
Measure the packed product
Use production-representative product dimensions, weight and fragile areas.
Prototype the structure
Test fit, opening, closing, assembly and packing before visual artwork is final.
Test the distribution route
Include stacking, handling, e-commerce or retail conditions that the pack will face.
Release the matched dieline
Link the final geometry, material and approved physical sample as one standard.
FAQ
Questions buyers often ask
How should a corrugated mailer box be designed?
Design from product restraint, board build-up, locking tabs, packing speed, opening experience, drop route and dimensional weight.
What should be written in the specification?
At minimum, define Flute and board build-up, Protection requirement, Distribution test, Logistics volume, then link quantity, sample, timing, inspection and the approved revision.
Is a physical sample needed?
A decision involving structure, material, colour, finish, assembly or use performance normally needs a physical sample matched to that question; a screen proof cannot approve everything.
Can the previous standard be reused for a repeat order?
Reuse a controlled standard only when files, material, structure, supply chain and use conditions remain unchanged. Record every change and decide whether resampling or reapproval is required.
