Structural Concept Design
Hand-sketched concepts and 3D CAD modeling to validate your packaging idea before investing in tooling or samples.
Dieline & Technical Drawing
Production-ready dieline files in AI, PDF, or DXF format — pre-checked for printability and manufacturing tolerance.
Physical Prototyping
Handcrafted white samples and full print-ready prototypes delivered in 3–5 working days for fit-testing and photography.
Tested for Transit
ISTA 2A and ASTM D4169 compliant structural solutions engineered to survive real-world courier and freight conditions.
Insert & Tray Engineering
Custom foam die-cuts, paper pulp molded trays, and cardboard inserts designed to secure your product and enhance unboxing.
Structure Meets Strategy
Engineering Packaging That Works as Hard as Your Product
Great packaging isn’t just about looks — it’s about physics, logistics, and brand perception working together. Our structural design team combines 20+ years of factory experience with advanced CAD modeling to engineer solutions that perform at every stage of the supply chain.
Whether you need a retail-ready shelf display, an e-commerce mailer built for 3-foot drop tests, or a luxury rigid box with magnetic closure, we design to your exact specs — and back every design with physical prototyping.
Reduce product damage by up to 40%
Cut material costs with right-sizing analysis
3–5 day structural sample turnaround
ISTA & ASTM drop-test compliance ready

From Concept Sketch to Production-Ready Dieline
Our end-to-end structural service covers every phase: conceptual sketching, 3D CAD modeling, physical prototyping, material selection, and final dieline delivery ready for print production. No back-and-forth with third-party designers — everything happens under one roof.
We specialize in complex structures including auto-lock bottoms, tear-strip mailers, multi-compartment inserts, and custom foam cut-outs engineered to your product’s exact form factor.
