The global food industry’s demand for safe, durable packaging has made food-grade woven fabric bags indispensable. At VidePak, we’ve spent 17 years perfecting these solutions, combining our team’s 150+ years of collective expertise with Austrian and German engineering precision. This report explores how our materials science, manufacturing rigor, and quality control systems ensure food safety while delivering packaging excellence.
Material Science: The Foundation of Food Safety
1. Virgin Polymer Selection
We exclusively use:
- PP Resins: Dow Chemical 7C50 (FDA 21 CFR 177.1520)
- PE Coatings: ExxonMobil LDPE 132i (EU 10/2011)
- Kraft Papers: Mondi Rotatrim (70–120 gsm, FSC-certified)
Critical Attributes:
- Purity: 0.2% max volatile content (TAPPI T413)
- Consistency: ±0.5% thickness tolerance (ISO 9073-2)
- Stability: 5% max moisture absorption (ASTM D6701)
2. Positive Tolerance Engineering**
Our bags feature:
- Thickness Overages: 5–10% above nominal specifications
- Burst Pressure: 1,200 kPa min (ASTM D3786)
- Seam Strength: 85% of bag body tensile strength
Quality Metrics:
| Parameter | Industry Standard | VidePak Specification |
|---|---|---|
| Thickness Variation | ±2% | ±0.5% |
| Burst Pressure | 800 kPa | 1,200 kPa |
| Seam Efficiency | 60% | 85% |
Manufacturing Excellence: Precision Meets Compliance
1. Equipment Synergy
Our facilities integrate:
- Starlinger viscotec: 16 extrusion lines for FIBC/PP bags
