The eight sections a bag factory reads before it can quote accurately and cut a pattern — and the gaps that most often slow a quote down.
A bag tech pack is the specification file a factory builds your bag from: dimensioned flat sketches, a bill of materials, a hardware list, construction callouts, Pantone colours, vector logo artwork with placement, and packaging instructions. A complete one lets a factory quote accurately and make a matched sample in about 1–2 weeks without guesswork. Every project here starts from something that already exists — a style on our shelf, a product on the market, a sample in hand, or a tech pack — so while your tech pack is still in progress, any of the other three gets your quote moving now.
| Section | What to include | Why the factory needs it |
|---|---|---|
| Flat sketches | Front, back, both sides, bottom, top and interior views, true to scale, plus an exploded view for layered parts | The pattern room cuts from these |
| Measurements | Overall height, width and depth in cm; every pocket; strap length and width; logo position — each with a tolerance | Dimensions drive fabric consumption and price |
| Bill of materials | Shell fabric (fibre, denier, coating — e.g. 600D polyester with PU coating), lining, foam and board thickness, webbing width | Materials are the largest cost driver |
| Hardware & trims | Zipper size and type for each opening (#5, #8, #10), sliders and pullers, buckles, D-rings, cord, labels | Hardware decides durability and is what buyers feel first |
| Construction | Seam types, edge binding or piping, bartacks at strap anchors, padding locations, stitches per inch | Construction sets the number of sewing operations — and the labour cost |
| Colours | A Pantone reference for each component: body, trim, lining, webbing, zipper tape | Colour matching needs a reference, not a description |
| Logo & labels | Vector artwork (AI, PDF or SVG), the method for each logo, its size and exact position | Decides the branding cost and the mockup |
| Packaging | Polybag, hangtag, barcode or FNSKU labels, pieces per carton | Changes landed cost and freight volume |
Fabric choices explained in 600D vs 900D; hardware and trim upgrades in component upgrades; logo methods in logo customization.
"A front pocket" can be 15 cm or 30 cm, and the price moves with it. Size every pocket.
Zipper size and type change both cost and durability. Name them for each opening.
We can redraw a JPG, but vector files go straight into the mockup and save a round of approvals.
The same bag is specified differently at USD 6 than at USD 14. The target price tells us which materials to quote.
A shelf style code with your changes, a photo of a style already on the market, or a physical sample gives our pattern room the same thing a tech pack does: a bag that already exists in some form. Many of our OEM projects start that way — see private label backpacks, OEM vs ODM, or all 229 ready-made styles.
The specification file a factory builds your bag from: flat sketches with dimensions, a bill of materials, a hardware list, construction details, Pantone colours, logo artwork and packaging instructions.
A PDF for the full pack, plus vector logo files (AI, PDF or SVG). A spreadsheet works well for the bill of materials.
Not necessarily. A style code from our shelf with your changes, a photo of a style on the market, or a physical sample work as starting points too. A complete tech pack is the most precise input.
Typically 1-2 weeks to make the matched sample, plus 3-7 days courier. It costs USD 30-300 by size and complexity and is refunded on the bulk order.
Commonly #5 for small pockets, #8 for main compartments on daypacks and #10 for heavy-duty or large openings. Name the size and type for every opening.
Add your quantity, target price and brand website — we reply with a quote and a sample plan within one to two working days.
