Production Workflow: From Raw Materials to Finished Goods

1. Raw Material Preparation

• Kraft Paper: 120-180gsm (bleached/unbleached, FSC® C123456).
• PP Granules: Virgin resin (ExxonMobil, 0.8 MFR).
• Adhesives: Water-based polyurethane (1.2g/m² coating).

Quality Control:

• Paper Testing: 3,000-cycle burst strength (TAPPI T807).
• Resin Analysis: 0.2% moisture content (Karl Fischer titration).

2. Extrusion & Lamination

• Starlinger viscos® V-1200: 5-layer co-extrusion (450kg/hr).
• W&H MIRAFLEX Press: 600m/min lamination speed.
• Tension Control: ±0.5N dynamic adjustment.

Quality Control:

• Adhesion Test: 4N/cm peel strength (ASTM D903).
• Thickness Gauge: ±2μm tolerance (ISO 9001:2015).

3. Woven Fabric Formation

• Circular Looms: 108 units (Starlinger RX 8.0).
• Weave Density: 9×9 to 14×14 threads/inch.
• Tensile Strength: 45 MPa (MD) / 40 MPa (TD).

Quality Control:

• Fabric Inspection: 100% defect detection (Cognex In-Sight).
• UV Stability: 1,200-hour QUV resistance (ASTM G154).

4. Printing & Finishing

• Flexo Printing: 8-color HD (KBA-Rapida 106, 600lpi).
• Coating: Matte/glossy aqueous finishes.
• Cutting: Ultrasonic precision (±0.5mm tolerance).

Quality Control:

• Color Matching: ΔE ≤1.5 (Pantone® system).
• Seal Integrity: 48-hour heat aging (ISO 11607).
