Custom Packaging Size and Structure Development
When a standard size or format does not fit your product, send us your technical brief. We will review the fit, dimensions, opening and inserts your packaging needs, and agree the scope with you before work starts.
Example drawing only, not a production dieline.

A Box Built Around the Product

Tap a pin to follow this concept from requirement to result.
Requirement
A small set needs a box that holds each piece apart in transit.
Structure
A rigid box is sized to the set, with dividers cut to fit each piece.
Review
A physical sample is checked with the real product before approval.
Costs, Revisions and Lead Times
Confirmed first
Costs depend on the structure and format. We confirm them with you before work starts.
Agreed in scope
We agree how changes are handled when we confirm your project scope.
Given with scope
Timing depends on the structure and sample stages, so we give it when your scope is confirmed.
Not every structure
If we cannot make what you need, we will tell you plainly. We do not offer certification or lab testing through this service.
Technical FAQs
When do I need this service?
When a standard format or size does not suit your product. If you only need help choosing from existing options, start with Packaging Consultation.
Can you use my existing dieline?
Send it with your brief, and we will review it with your other requirements.
Which files should I send?
Send sketches, photos or dielines in the format you have. For artwork, vector files such as AI, EPS or PDF are best.
Can I test the structure before ordering?
Yes. You can ask for a physical sample, and we confirm its cost with you before it is made.
Do you certify packaging performance?
No. Test the packaging with your product, and confirm any rules that apply in your market.
