Structural Design

CAD, dielines, and prototypes built around real production needs

Netpak’s packaging engineers develop folding carton structures that fit the product, board grade, filling method, glue pattern, retail presentation, and production constraints. The goal is not only to create a dieline, but to create a structure that folds, protects, displays, and converts reliably.

From initial CAD dieline to blank prototype, Netpak helps validate structure before production. That reduces avoidable artwork changes, tooling risk, assembly issues, and print-production delays.

  • 1CAD dielines tailored for accurate folding carton production.
  • 2Physical blank prototypes for structure, fit, and pack-out validation.
  • 3Structural design optimized for durability, display, packing speed, and cost control.
Custom die-cut insert and folding carton prototype for structural validation
Physical prototypes and inserts help validate product fit, pack-out, protection, and assembly before artwork is treated as final.
Prepress colour management and print file preparation for folding cartons
Colour verification, file preparation, print constraints, finishing zones, and plate readiness should be resolved before the project reaches press.
Prepress Expertise

File prep, colour control, and CTP plates managed before press

Netpak handles the technical prepress work that determines whether packaging files print cleanly. The team checks file setup, production requirements, colour expectations, print constraints, dieline alignment, finishing effects, and regulatory layout needs before the run moves forward.

In-house CTP plate production keeps the process faster and more controlled. It also reduces avoidable handoffs between design approval, prepress correction, and press readiness.

  • 2Colour verification to keep packaging aligned with brand standards.
  • 3In-house CTP plate production for faster, more controlled print readiness.

Why Netpak

Strong structural foundations for cleaner production results

Netpak is a full-service North American folding carton partner, connecting structural design, prepress, printing, finishing, warehousing, and logistics in one production workflow.

Structure and prepress that reduce production friction

The best carton programs solve design, structure, board, file setup, proofing, colour, and tooling questions before production begins.

  • ✓Engineering-led dielines: structures are developed around the product, board, filling line, display requirements, and converting behavior.
  • ✓Prototype validation: blank samples help confirm fit, folds, panels, closures, pack-out, and retail presentation before production.
  • ✓Prepress discipline: files, colour, dieline alignment, finishing zones, and regulatory needs are checked before plates are made.
  • ✓Production continuity: CTP plate production, printing, finishing, warehousing, and logistics stay connected through one supplier workflow.

Workflow Overview

Structure and prepress steps before production

A controlled workflow keeps CAD, prototype validation, file preparation, colour verification, and plate production aligned before the carton moves to press.

Structure & Prepress Workflow Overview

StageWhat We DoWhy It Matters
1 CAD & Dieline
Develop an accurate structural dieline using CAD.Ensures fit, folding accuracy, panel control, board optimization, and production alignment.
2 Prototype
Build a blank prototype for validation.Confirms structure in real space before tooling, artwork release, or production commitment.
3 File Preparation
Prepare print-ready files that respect design intent and production constraints.Avoids print errors, dieline mismatch, missing bleed, finishing conflicts, and file rework.
4 Colour Verification
Confirm print colour matches brand and production expectations.Supports accurate, consistent colour results across cartons, SKUs, and production runs.
5 CTP Plate Production
Produce plates in-house for printing.Speeds timeline, improves control, and keeps press readiness connected to approved files.
Service Capabilities

What Netpak reviews before a carton reaches production

Structure and prepress decisions determine whether a carton runs cleanly. Netpak reviews the practical details that affect folding, gluing, printing, finishing, compliance, and supply timing.

Dieline accuracy

Panel geometry, score layout, glue flaps, bleed, closures, and fold behavior are reviewed before production files are finalized.

Prototype validation

Blank prototypes help confirm product fit, assembly, closure behavior, pack-out, shelf presentation, and structural tolerance.

Colour management

Colour targets, proof expectations, board surface, ink behavior, varnish, and finishing effects are considered together.

File preparation

Prepress checks help catch missing assets, incorrect file setup, dieline conflicts, barcode issues, and production risk before plates.

Regulatory layout support

Food, pharma, health and beauty, and retail programs often require stricter hierarchy, symbol placement, warning panels, or bilingual layout control.

Plate readiness

In-house CTP plate production keeps approved file preparation connected to press scheduling and final output control.

Frequently Asked Questions

Common structural and prepress questions

Answers to common questions about CAD dielines, prototypes, existing files, prepress specs, colour proofing, multi-SKU programs, regulated categories, and shipping.

Can Netpak create the CAD dieline for my product?

Yes. Netpak’s packaging engineers can build production-ready CAD dielines from product dimensions, packaging requirements, or a physical sample. The dieline can account for folds, glue flaps, board choice, tolerances, product fit, and efficient converting.

What do you need to start a structural design?

Helpful inputs include product dimensions, product weight, pack-out method, current packaging samples, target board, closure preference, retail display requirements, regulatory needs, shipping path, and launch timing.

Will I receive a prototype before production?

Yes, prototypes can be produced to validate form, fit, folding behavior, assembly, product protection, and display performance before production proceeds.

Can you work from my existing dieline?

Yes. Netpak can review an existing dieline for production readiness, board fit, glue areas, panel geometry, finishing zones, artwork alignment, and conversion risk.

What file specs should I use for prepress?

Send production artwork with linked or embedded assets, proper bleed, dieline layer separation, fonts outlined or packaged, correct colour setup, barcode requirements, and any finishing layers clearly identified. Netpak can confirm project-specific file requirements before release.

Do you manage colour and proofs?

Yes. Netpak supports colour verification and production review so the final carton is aligned with approved artwork, substrate behavior, ink performance, and brand expectations.

Can you handle multiple SKUs in one run?

Often, yes. This depends on SKU count, artwork variation, board selection, print strategy, finishing needs, run size, and changeover requirements.

Do you support food, health and beauty, and pharma requirements?

Yes. Netpak supports regulated and retail-facing categories where packaging must account for material controls, layout discipline, colour consistency, traceability, and buyer expectations.

Where do you ship?

Netpak supports North American folding carton programs, including Canadian and U.S. customers that need production, warehousing, staged delivery, or multi-location shipping.
