When Packaging Failures Threaten Bottom Lines
Material engineers confront three critical challenges in bulk logistics:
- Product Waste: 17% of powdered goods lost through fabric pores
- Regulatory Penalties: 23% of shipments rejected for UN certification gaps
- Contamination Costs: $4.2B annual global expenditure on cargo cleanup
VidePak’s leakproof woven bags address these challenges through:
- 16 Starlinger RV 13i Extruders: Processing 1,800 tons/month of virgin PP
- 8 W&H MIRAFLEX II Presses: Delivering 8-color prints with 0.05mm registration
- 120+ Circular Looms: Weaving 55-180g/m² fabrics with ±0.1mm tolerance
Certification Highlights:
- ISO 22000:2018: Food safety management certification
- TÜV SÜD: Leakproof performance verification (Report #VN-25-342)
- ASTM D7759: Top-lift test compliance
Customization Engine: From Concept to Commercialization
Our 6-axis customization system delivers tailored containment solutions:

3. Seam Engineering
- Stitch Density: 8-12 stitches/inch (ISO 4916)
- Thread Strength: 45-60 N (ASTM D2256)
- Heat Sealing: 2-5mm widths with 95% bond rates
4. Testing Protocols
- Drop Test: 1.2m (ASTM D5276)
- Leak Test: 50kPa pressure (ISO 11504)
- UV Exposure: 1000 hours (ASTM G154)
QC Note: “Our hydrostatic pressure tester rejects 0.8% of seams through AI-driven acoustic emission detection.”
