Our Multi-Layer QC Workflow
Present your production-stage inspections in a step-by-step chart for clarity:
| Stage | Inspection Focus | Why It Matters |
|---|---|---|
| 1. Incoming Material Check | Fabric, zippers, buckles, lining, webbing | Avoids production delays and material mismatches |
| 2. Sample Testing & Client Approval | Structure, stitching, logo placement | Ensures prototype meets branding and functionality expectations |
| 3. Pre-Production QC | Small-batch run to validate machinery & team readiness | Prevents mass errors from scaling issues |
| 4. In-Line Production Checks | Stitching tension, measurement accuracy, logo application | Early defect detection during sewing and assembly |
| 5. Final Product QC | 100% or AQL sampling — includes dimension check, logo review, seam stress, zipper pull test | Guarantees that final bags match the signed sample |
| 6. Pre-Packing Inspection | Packaging specs, barcoding, FBA label accuracy | Ensures retail compliance and proper shipping condition |
In-House Testing Capabilities
We maintain a dedicated area in our factory for key testing procedures:
Fabric strength testing (tear and tensile resistance)
Waterproof or fireproof validation
Colorfastness testing (to light, rub, and wash)
Zipper pull cycle testing (open/close repetition)
Handle & strap load-bearing test (stress point validation)
Logo adhesion test (screen print, heat transfer, embroidery durability)
Barcode and label scan test for retail logistics
Measurement & Tolerance Control
All bag components are measured with precision tools
Stitch count, panel alignment, pocket position, and zipper placement follow CAD standards
Tolerances allowed within ±5mm unless otherwise specified
Weight and volume checks for cooler bags, dry bags, and tool bags
We strictly follow your technical packs or approved samples.
QC Documentation & Traceability
Every order is backed with real-time QC records, including:
Product QC checklist (per style)
In-line and final inspection reports
Material lot tracking
Photo and video confirmation before shipping
QR-coded internal tracking per order

Packaging Quality Control
We know packaging matters — especially for retail and e-commerce.
Standard export cartons with strength tested (3-5 layer)
Custom inner packing (OPP, PE, Kraft, zipper pouches, tissue wrap)
Logo-printed polybags and hang tags (optional)
FBA-compliant labeling, barcode accuracy, SKU matching
