Kraft Paper Woven Bags: Merging Strength and Sustainability Through Advanced Lamination

How Kraft Paper and PP Woven Fabrics Become One

The creation of Kraft Paper Woven Bags involves a meticulous three-stage process that fuses natural fiber aesthetics with polypropylene durability:

1. Surface Preparation: Building the Perfect Bond

  • Paper Treatment: Corona discharge units elevate surface energy to 2.5-3.0 dyne/cm
  • PP Film Extrusion: Starlinger PEX 1200 lines produce 20μm sealant layers
  • Priming: Water-based polyurethane coatings ensure 3-5g/m² adhesion

2. Lamination: The Heat and Pressure Dance

  • Temperature Control: Precision-engineered 85-95°C extrusion coating
  • Pressure Application: TÜV SÜD-certified 4-6kg/cm² nip rolls
  • Speed Management: 150-180 meters/minute line synchronization

3. Finishing: The Final Quality Seal

  • Curing: 48-hour climate-controlled conditioning (23°C/50% RH)
  • Testing: 180° peel strength exceeding 3.5N/cm (ASTM D903)
  • Inspection: AI-powered vision systems detect 0.2mm defects
