How to Prepare a Tech Pack for Custom Bag Manufacturing
A practical checklist for brands preparing bag dimensions, materials, construction details, hardware, branding, packaging, and sample requirements.
A clear tech pack helps a bag factory understand your design, prepare a more accurate sample, and identify open questions before production. It does not need to be visually complicated, but it should make the product requirements easy to review.
- Start with the product overview
Include the bag type, intended market, target customer, expected use, and reference images. State whether the project is a new design, a modification of an existing style, or development from a physical sample.
- Provide dimensions and construction views
List the finished width, height, and depth, together with strap lengths, handle drop, pocket sizes, and important internal measurements. Front, back, side, top, bottom, and interior views help the factory understand the complete structure.
- Specify materials clearly
Identify whether the main material should be genuine leather, PU leather, microfiber leather, textile, or a combination. Add preferred texture, color references, lining material, reinforcement needs, edge finishing, and any performance expectations. If the final material is not decided, explain the price level and market position so suitable options can be discussed.
- Detail hardware and components
Show the required zippers, sliders, buckles, clasps, magnetic closures, feet, rings, chains, and other metal parts. Include finish colors such as light gold, antique brass, gunmetal, or silver. Mark any custom molds or engraved parts separately because they can affect development time and cost.
- Explain branding requirements
Indicate the position, size, color, and method for each logo. Common options include metal logos, embossed or debossed leather, screen printing, woven labels, lining prints, zipper pull logos, and packaging marks. Vector artwork is normally more useful than a low-resolution image.
- Add stitching and workmanship notes
Specify visible stitch color, stitch distance, edge paint color, piping, quilting, reinforcement points, seam construction, and any areas that require special attention. Close-up reference images are useful when a written note could be interpreted in different ways.
- Define packaging expectations
List dust bags, tissue, shape support, polybags, hangtags, labels, barcode stickers, cartons, and any retailer-specific packaging requirements. Packaging should be discussed before the production quotation because it affects materials, labor, and shipping volume.
- State sampling and approval needs
Explain which sample stage is required and who will approve materials, colors, hardware, logos, and final construction. Keep a written record of approved changes so the production version matches the confirmed sample.
- Separate confirmed requirements from open questions
Mark each point as confirmed, preferred, or open for factory recommendation. This makes communication faster and prevents an undecided detail from being treated as final.
- Share commercial context without inventing specifications
Provide the target market, estimated order range, required delivery window, testing or compliance needs, and target price positioning when available. The factory can then evaluate suitable materials and construction methods. Final MOQ, pricing, and lead time should be confirmed after reviewing the complete design and sample requirements.
A useful tech pack reduces repeated questions, but product development is still collaborative. Joycan Bag supports OEM and ODM projects in genuine leather, PU leather, and microfiber leather, from material discussion and sampling through production, inspection, packaging, and delivery coordination. Send your design, reference sample, or existing specifications to begin the review.
