# Mingzhe FIBC factory and quality control

## Six in-house steps

1. **Yarn drawing** — Virgin PP resin is extruded into film and slit into flat tape yarn on our own drawing lines. Using only new material here is what keeps the fabric strength consistent.
2. **Winding** — The tape yarn is wound onto bobbins on take-up machines, ready to load onto loom creels and webbing looms.
3. **Circular weaving** — Circular looms weave the yarn into tubular PP fabric, the body of every bag. Double-warp fabric is woven for bags that need a stronger body.
4. **Webbing (lifting loops)** — Webbing looms weave the belts used for lifting loops and reinforcement straps. Widened, thickened straps are the foundation of a bag’s load-bearing strength.
5. **Coating** — Fabric for waterproof and moisture-resistant bags is coated (laminated) on our coating line. Uncoated fabric is used where the product needs to breathe.
6. **Cutting & sewing** — Fabric is cut in the cutting workshop and sewn into bags with lifting loops, spouts and anti-leak strips. Lock-edge seams and double stitching keep seams from opening or skipping.
