Modern industries demand packaging solutions that combine durability, safety, and precision. At VidePak, we specialize in producing anti-static heavy duty woven bags with load capacities ranging from 500 kg to 2,000 kg, backed by stringent quality control protocols that ensure compliance with global standards. Our 30+ years of expertise, advanced Austrian Starlinger machinery, and commitment to using 100% virgin PP/PE materials position us as a leader in bulk packaging solutions.
1. The Science of Load Capacity in Anti-Static Woven Bags
Heavy duty woven bags are engineered to withstand extreme weights while maintaining structural integrity. At VidePak, our anti-static variants incorporate conductive filaments or coatings to dissipate electrostatic charges—a critical feature for industries handling flammable or sensitive materials like chemicals, fertilizers, or electronic components.
Key Parameters Influencing Load Capacity
- Material Strength: Our bags use high-tenacity polypropylene (PP) yarns with tensile strengths exceeding 5.5 g/denier, ensuring resistance to tearing under stress.
- Weave Density: With 12×12 to 14×14 threads per square inch, our weaving process optimizes balance between flexibility and rigidity.
- Lamination: BOPP lamination enhances load-bearing capacity by 30%, as demonstrated in our tests for 50 kg cement bags subjected to 1.5× overload simulations[citation:42][citation:55].
Case Study: A client in the fertilizer industry reported a 40% reduction in transport damage after switching to VidePak’s laminated woven bags, which sustain loads up to 1,200 kg without seam failure.
2. Rigorous Quality Control: From Raw Materials to Finished Products
Quality begins with raw material inspection. Our PP/PE granules undergo 14+ tests to ensure consistency, safety, and performance.
Quality Assurance for PP Granules (Outer Bag)
| Test Category | Parameters | Industry Standards |
|---|---|---|
| Physical Properties | Melt Flow Index (MFI): 2–4 g/10 min | ASTM D1238 |
| Density: 0.905–0.925 g/cm³ | ISO 1183 | |
| Mechanical Performance | Tensile Strength: ≥35 MPa | ASTM D638 |
| Impact Strength: ≥50 kJ/m² | ISO 179 | |
| Thermal Stability | Heat Deflection Temp: ≥100°C | ASTM D648 |
| Visual Inspection | Color uniformity, no impurities | AQL Level II (ISO 2859-1) |
Additional Tests for PE Liners (Inner Bag)
- Film Impact Resistance: Dart drop tests (ASTM D1709) ensure PE liners withstand ≥500 g impacts without puncture.
- Anti-Static Verification: Surface resistivity ≤10¹² Ω/sq (per IEC 61340-4-1).
VidePak’s Approach: Our in-house lab uses Instron tensile testers and DSC analyzers to validate every batch. For example, a 2024 audit revealed <0.1% defect rates across 10,000+ bags—a testament to our ISO-compliant processes[citation:63][citation:72].
3. VidePak’s Manufacturing Excellence
Founded in 2008 and led by CEO Ray, VidePak operates 100+ circular looms and 30 lamination machines, enabling an annual output of 120 million bags. Our capabilities include:
- Customization: Multi-color printing (up to 8 Pantone shades), UV resistance coatings, and sizes from 25 cm × 40 cm to 110 cm × 220 cm.
- Sustainability: Recyclable PP materials align with EU Packaging Directive 94/62/EC.
Global Reach: With $80 million in annual sales and clients across 50+ countries, we serve industries from agriculture (e.g., FIBC bags for grain) to construction (woven bags for cement).
