Tech pack format
Tech pack format: what goes in it, including your packaging
A tech pack is the set of technical documents that tells a factory exactly how to make and pack your product, and its usual format runs from drawings and measurements to materials, labels, and packaging.
Production-ready tech packs that factories understand are part of Cydney Mar's product development work. In her words, a clear, professional tech pack is the difference between a sample that is right the first time and months of expensive back-and-forth.

What is the standard tech pack format?
A typical tech pack has a cover page, technical drawings, a measurement or spec sheet, a bill of materials, construction notes, colorways, label and trim details, packaging specs, and quality notes. Exact sections change by product category and factory, so ask your manufacturer what they expect before you send it.
The section founders most often forget is packaging. Leaving it out invites surprises in quote, lead time, and how units arrive.

| Measurements and specs | Dimensions and tolerances | Inner and outer package dimensions |
| Bill of materials | Every material and component, with suppliers | Board or film type, inserts, closures |
| Construction notes | How parts are assembled | How the product sits in the package |
| Colorways and artwork | Color references and placements | Print colors, finishes, artwork files |
| Labels and trims | Brand labels, care or ingredient labels | Barcodes and required on-pack information |

Why the tech pack matters
Definition
What a tech pack is for
A tech pack turns a product idea into instructions a factory can follow without guessing. Cydney Mar calls product development her craft, and production-ready tech packs sit at its center along with sampling, sourcing, costing, and production readiness. In the Concept-to-Reality Pathway, the tech pack supports Right Prototypes, where the goal is the right samples with less rework, and Production-Ready, where specs are finalized for consistent manufacturing.
Warning signs
Signs your tech pack needs work
- Samples keep coming back with the same problems
- Factory quotes vary widely for what should be the same product
- Packaging is described in emails but not in the document
- Measurements have no tolerances
- Materials are named by look rather than by specification
Procedure
How to build a tech pack, step by step
Start from a clear product definition
Know exactly what you are making and for whom before drawing anything.
Draw and measure
Create technical drawings and a measurement sheet with tolerances.
List every material
Build the bill of materials, including packaging components.
Add packaging and packing
Specify the package, inserts, labels, and units per carton.
Review with the factory
Ask what is unclear, update the document, and keep version numbers.
Packaging specs feed straight into cost and lead time, and into how the product looks on a retail shelf.

Common questions
See all 46 questions- What is a tech pack?
- A tech pack is the set of technical documents that tells a factory exactly how to make your product: drawings, measurements, materials, construction, colors, labels, and packaging. Cydney Mar describes a clear, professional tech pack as the difference between a sample that is right the first time and months of expensive back-and-forth.
- What is the usual tech pack format?
- A typical tech pack format includes a cover page with product details, technical drawings, a measurement or spec sheet, a bill of materials, construction notes, colorways, label and trim details, packaging specs, and quality notes. Exact sections vary by product category and factory, so confirm what your manufacturer expects before you send it.
- Should packaging go in the tech pack?
- Yes, generally. Including packaging specs such as box or bag type, dimensions, materials, inserts, labels, and how units are packed helps the factory quote accurately and deliver consistent product. Leaving packaging out of the tech pack is a common source of surprises in cost and lead time once production starts.
- Does Cydney Mar create tech packs?
- Yes. Production-ready tech packs that factories understand are part of Cydney Mar's product development work, along with sampling, sourcing, costing, and production readiness. She calls product development her craft and the work she loves most, and it is where decades of hands-on experience save founders the most time and money.
- Why does a tech pack matter for getting samples right?
- A factory can only build what it understands. A tech pack with clear drawings, measurements, materials, and packaging details reduces guesswork and back-and-forth during sampling. In Cydney Mar's pathway, Right Prototypes means developing the right samples and cutting costly rework, and Production-Ready means finalizing specs for consistent manufacturing.
- My samples keep coming back wrong. What should I do?
- Look at what the factory received. Repeated wrong samples usually point to missing or unclear specs, so tighten the tech pack with drawings, measurements, materials, and packaging details. Cydney Mar's Right Prototypes step is about developing the right samples and cutting costly rework, and production-ready tech packs are a core part of her work.
