Private label manufacturing

Custom Bag Manufacturing Tailored to Your Brand

From a sketch or tech pack to retail-ready cartons under your label: twelve stages, each with what you send, what we do and what you receive. This is the exact process every Senszx private-label order follows - shown with photos from our own floor.

  • 12 documented stages
  • Free tech pack
  • 10 branding methods
  • MOQ 100 / 20-day bulk

From Design to Sample

What you get

Your brand on every touchpoint - not just a printed logo

Private label at Senszx means the bag, its lining, hardware, labels, hang tag, polybag and carton all carry your identity, and the whole chain is built in one factory so nothing is lost between suppliers.

Pattern designer at Senszx

Design ownership

Your tech pack, or one we build for you free, stays yours. Files on an access-controlled server, NDA before we open anything.

Senszx sewing lines

One roof, one standard

Cutting, printing, embroidery, sewing, QC and packing in one building. No subcontractors means one sealed sample governs everything.

Rigid gift box packaging

Retail-ready out of the carton

Hang tags, barcodes, polybags, gift boxes and carton marks to your spec - goods go straight to shelf or FBA.

The process, stage by stage

Twelve stages from brief to re-order

Every stage lists what we need from you, what happens inside the factory and what you receive at the end. Typical timing for a first order is shown; re-orders start at stage 6.

  1. Senszx sales engineer reviewing a buyer brief with fabric swatches01

    Brief & feasibility

    Day 0-1

    A sales engineer reads your sketch, reference photo or tech pack and checks it against what our lines can build at your target price. We flag anything that will not work before you spend time on it.

    You send / decide

    • Bag type, quantity per colour, destination market
    • Reference photos or tech pack; a target price if you have one
    • Logo artwork (vector) and where it goes

    We do

    • Feasibility check: fabric, construction, hardware, compliance
    • Open-question list - only what changes the quote
    • Rough price band at 100 / 500 / 1,000 pcs

    Output: Written feasibility note and price band within 12 hours

  2. CAD pattern room at Senszx bag factory02

    Design & tech pack

    Day 1-3

    If you have a full tech pack we digitise it; if you have a sketch we build the tech pack for you at no charge: flats, dimensions, bill of materials, construction notes, logo placement and packing spec. ODM projects get photoreal renderings in your colours.

    You send / decide

    • Approve or mark up renderings and flats
    • Confirm dimensions (carry-on limit? laptop size?)

    We do

    • 2D flats front / back / side / interior
    • BOM with fabric articles, zipper sizes, hardware finishes
    • Renderings in up to 3 colourways (ODM)

    Output: Tech pack v1 - the document every later stage is checked against

  3. Polyester colour swatch book used for Pantone lab dips03

    Materials & lab dips

    Day 3-6

    We pull fabric from stock or dye to your Pantone, source hardware in a matched finish and cut swatches. Every fabric article is tested for weight, coating and colour fastness before it is approved for your sample.

    You send / decide

    • Pick fabric option (we propose 2-3 at different price points)
    • Approve lab dip against your Pantone reference

    We do

    • Lab dip within 3 days; strike-off of your logo on the real fabric
    • Hardware card: slider, pull, buckle, ring in your finish
    • Incoming fabric test: GSM, coating, rubbing fastness

    Output: Approved swatch + hardware card, sealed for bulk

  4. Sample sewing station in the Senszx pattern room04

    Pattern & first sample

    Day 6-10

    The pattern maker cuts the digitised pattern on our CNC plotter and a sample sewer builds the bag on production machines with production materials - so the sample is what bulk will be, not a hand-made showpiece.

    You send / decide

    • Review photos first (day 8-9), then the physical sample
    • Send numbered revision notes against the photos

    We do

    • Production-grade sample in 3-5 working days
    • Photo set: front, back, side, interior, every logo, on a scale
    • Courier by DHL/FedEx; unlimited revision rounds

    Output: Sample v1 in your hands ~10 days after brief

    From Design to Sample

  5. Sample room materials table at Senszx05

    Revision & sign-off

    Day 10-16

    Most projects approve on the first or second sample. We seal the approved sample on the QC floor as the bulk inspection standard and issue the pro-forma invoice with lead time written in.

    You send / decide

    • Written approval of sample + tech pack v2
    • 30% deposit by T/T (or L/C for larger orders)

    We do

    • Sealed reference sample and hardware card
    • Pro-forma with MOQ, price, lead time, Incoterm, payment terms
    • Fabric and hardware purchase orders placed same day

    Output: Signed PI; 20-day production clock starts

  6. Senszx sewing workshop06

    Pre-production meeting

    Day 17

    Line leader, cutting supervisor, QC lead and your sales engineer walk the sealed sample operation by operation: sequence, jigs, stitch density, bartack positions, tolerance on every dimension. Problems are solved here, on one bag, not on a thousand.

    You send / decide

    • Nothing - but you receive the meeting notes

    We do

    • Operation sheet for the line
    • Jigs for print placement and PALS spacing
    • First-piece approval plan

    Output: Operation sheet and pilot-run plan

  7. CNC cutter cutting backpack panels from the approved CAD file07

    Cutting, printing, embroidery

    Day 17-20

    Panels are CNC-cut from the same file as the sample. Logos go on flat panels before sewing - screen print, heat transfer, embroidery, sublimation - so placement is exact and prints never distort over a seam.

    You send / decide

    • Approve first-piece photos of print/embroidery

    We do

    • CNC cutting; bundles ticketed per style and size
    • In-house printing and 6 embroidery heads
    • First-piece check against strike-off

    Output: Cut and branded panel bundles released to sewing

    Backpack Front Panel Production

  8. Backpack sewing line at Senszx08

    Sewing & assembly

    Day 20-32

    One style per line. Sub-assemblies - padded back panel, straps, organiser panel, laptop sleeve - are sewn first and checked, then the body comes together. In-line QC pulls every 200th bag against the sealed sample.

    You send / decide

    • Optional: live video of your line on WhatsApp

    We do

    • Line-balanced production, 8-12 min per bag
    • In-line QC every 200 pcs: stitch density, bartacks, zipper run, logo
    • Daily output report on request

    Output: Finished bags flowing to QC at the agreed daily rate

  9. 100% final inspection line at Senszx09

    Final inspection

    Day 32-35

    Every bag is opened, every zipper run, every logo and dimension checked against the sealed sample. Then an AQL 2.5 audit on a random sample produces the photo report you receive before paying the balance.

    You send / decide

    • Review inspection report; book third-party inspection if you wish
    • 70% balance against report + B/L copy

    We do

    • 100% inspection + AQL 2.5 audit
    • Photo report: defects found, corrected, measurements
    • Needle-detector pass on children's bags

    Output: Inspection report and release for packing

Private-label manufacturing FAQ

What is the difference between private label and OEM?
In bag manufacturing they overlap. Private label means the finished bag carries your brand; OEM means we make it to your design. Most private-label orders are OEM. If you do not have a design, ODM (we design, you brand) is also private label.
Do I need a tech pack to start?
No. A sketch, a photo of a bag you like, or a competitor sample is enough; we build the tech pack for you free of charge during stage 2. If you do have one, we digitise it and flag anything that will not work at your price.
How long from first message to goods shipped?
Typically 5-6 weeks for a first order: 10 days to a sample in your hands, a few days for your review, 20 days production, 1-2 days loading. Re-orders skip sampling and ship in 20 days.
What is the MOQ and can I mix colours?
100 pieces per style. Colours can be split within a style (e.g. 50 black + 50 navy) at a small surcharge for the extra lab dip. Mixed styles combine on one PI and ship in one container.
Which logo method should I choose?
Screen print for 1-4 colour logos at the lowest cost; embroidery for a premium, durable look; heat transfer for photographic artwork; woven label inside every bag; metal plate or debossed patch for business and fashion lines. Most bags use two or three methods together - we propose a combination in the quote.
Can you match my brand Pantone exactly?
Yes. We dye fabric, webbing, binding and zipper tape to your Pantone and send a lab dip for approval before bulk. Stock colours (60+ on 600D polyester) are available at any quantity without a dye lot.
Do you provide retail-ready packaging?
Yes. Hang tags, barcodes, polybags with warning text, dust bags, gift boxes, inner boxes and printed cartons. For Amazon FBA we apply FNSKU labels and follow the polybag and carton rules so goods check in without repacking.
How do you protect my design?
We sign your NDA or provide ours before opening files. Files are kept on an access-controlled server, moulds and screens are stored per customer, and we do not show or sell customer designs to other buyers.
What if the bulk does not match the sample?
It is inspected against the sealed sample before you pay the balance. Confirmed defects are repaired, replaced or credited - stated on every pro-forma invoice. Sample-to-bulk drift is prevented by sewing samples on production machines with production materials.
Can I visit or audit the factory?
Yes - in person in Baigou (90 minutes from Beijing), by live video tour on WhatsApp within 48 hours, or through SGS/BV/TUV/Intertek at any stage at your cost.
What certifications and tests do you provide?
BSCI, ISO 9001, ISO 14001, ISO 45001 and CE at factory level. Product tests (REACH, CPSIA, Prop 65, azo dyes, phthalates) arranged through third-party labs per order; reports travel with the shipping documents.
Do you offer payment terms?
First orders: 30% deposit, 70% against inspection report and B/L copy. L/C at sight for orders above USD 50,000. Repeat customers with a 12-month history may qualify for terms on the balance.
