Valve Bags: Engineering Storage Excellence Through Material Science

The Hidden Costs of Poor Storage Practices

Logistics professionals often grapple with three critical storage challenges:

  • Material Fatigue: 22% of valve bags degrade prematurely in warehouses
  • Collapsing Risks: 18% of storage incidents involve unstable pallet configurations
  • Compliance Penalties: $120,000 average fine for non-conforming packaging

VidePak’s valve bags tackle these issues through:

  • 16 Starlinger RV 13i Extruders: Processing 1,800 tons/month of virgin PP with 0.2mm precision
  • 8 W&H MIRAFLEX II Presses: Delivering 8-color prints at 1,200 bags/hour throughput
  • 120+ Circular Looms: Weaving 55-180g/m² fabrics with ±0.1mm dimensional consistency

Certification Highlights:

  • TÜV SÜD: Stacking Stability Verification (Report #VN-25-472)
  • ISO 22000:2018: Food Safety Management Certification
  • FSC® Certification: Chain of Custody #C154678 for Responsible Sourcing
