The global packaging industry’s embrace of Custom Woven Bags underscores their unique ability to deliver tailored strength, print precision, and environmental resistance. At VidePak, we’ve spent 17 years refining these solutions, merging our team’s 150+ years of collective expertise with Austrian/German engineering precision. This report explores material science breakthroughs, rigorous quality control protocols, and the technical edge delivered through our fine filament technology.
Fine Filament Innovation: The Anatomy of Performance
1. Material Specifications
Our woven fabrics utilize virgin polypropylene (PP) resins meeting exacting standards:
- Melt Flow Index (MFI): 2–6 g/10min (ASTM D1238) – critical for consistent extrusion
- Tensile Modulus: 1.8 GPa (ISO 527) – ensures structural integrity under load
- Elongation: 25–35% (ASTM D638) – balances flexibility with puncture resistance
Filament Diameter Ranges:
| Application | Denier (g/9000m) | Tex (g/1000m) | Twist (TPM) |
|---|---|---|---|
| Agricultural Bags | 800–1,200 | 90–135 | 300–400 |
| Industrial Packaging | 1,400–1,800 | 155–200 | 200–300 |
| Retail Carriers | 600–900 | 65–100 | 400–500 |
