Structural decision
Four checks before freezing the structure
Finished dimensions
Record internal and external size, measuring method and acceptable tolerance instead of relying on a photo or nominal size alone.
Tolerance stack-up
Review how material, printing, die cutting, gluing and packed-product variation combine at final assembly.
Stiffness and forming
Evaluate folding, scoring, opening force and load support on the intended structure rather than judging material only by hand feel.
Artwork ownership
Freeze approved copy, logos, legal marks, languages and version responsibility before output; production checks do not replace content approval.
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 packaging sleeve be designed?
Control product or box clearance, seam, opening direction, paper stiffness, artwork wrap and friction through repeated fit trials.
What should be written in the specification?
At minimum, define Finished dimensions, Tolerance stack-up, Stiffness and forming, Artwork ownership, 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.
