In the intricate world of industrial packaging, Kraft paper laminated woven bags represent the pinnacle of engineered solutions. At VidePak, we’ve spent nearly two decades refining this technology, blending Austrian precision with German engineering to deliver packaging that withstands the world’s harshest logistics environments. This isn’t just about combining materials—it’s about creating systems that protect, perform, and enhance brand equity.
The Manufacturing Symphony: Starlinger & W&H Equipment in Action
1. Extrusion Excellence: W&H’s Molecular Control
Our 16 W&H extrusion lines operate with surgical precision:
- Resin Conditioning: Cryogenic grinding ensures 99.8% particle uniformity
- Die Design: Patented spiral mandrels eliminate melt fractures
- Cooling Innovation: 25°C ±1°C water baths for defect-free crystallization
These systems achieve:
- Tape Thickness Control: ±0.015mm via laser micrometers
- MFI Consistency: 2.8 g/10min ±0.2 (ASTM D1238)
- Energy Efficiency: 18% below industry average consumption
2. Weaving Mastery: W&H Circular Looms
The heart of our operation lies in 100+ W&H looms featuring:
- Positive Let-Off (PLO) System: Maintains ±1 warp/inch density
- Real-Time Defect Detection: 4K cameras repair irregularities at 800m/min
- Servo-Driven Tension Control: 0.3% elongation tolerance
Client Impact:
A South African fertilizer manufacturer reduced weaving defects by 92% after switching to VidePak bags, cutting rework costs by $180,000 annually.
3. Lamination Artistry: Starlinger’s viscotec Technology
Our 30 Starlinger viscotec units execute a three-stage lamination process:
- Adhesive Application: 4.5 g/m² ±0.15 coating weight
- Infrared Drying: 85°C surface temperature control
- Tension Equalization: 0.5% elongation matching between layers
This results in:
- Bond Strength: 4.2 N/15mm (ASTM D903)
- Delamination Resistance: 99.2% after 72h condensation testing
- OTR Performance: <4.5 cc/m²/day (Mocon OP-Test)
4. Printing Precision: 8-Color Gravure Mastery
Our rotary presses combine:
- Laser-Engraved Cylinders: 1,000-line screens for Pantone® accuracy
- UV-LED Curing: Instant polymerization at 600m/min
- Color Consistency: ΔE <1.5 across 10,000m rolls
Certification:
- G7 Master Certification: Color management excellence
- FDA Compliance: Direct food contact approval
Equipment Comparison: Starlinger vs. W&H – Engineering Philosophies
| Metric | Starlinger Lamination | W&H Weaving |
|---|---|---|
| Precision | ±0.15g adhesive control | ±1 warp/inch density |
| Uptime | 98.2% (2024 OEE) | 97.5% (2024 OEE) |
| Maintenance | Self-diagnosing bearings | Predictive analytics |
| Power Consumption | 0.45 kWh/kg | 0.52 kWh/kg |
Why This Matters to You
- Consistency: <0.3% variation in burst strength across batches
- Throughput: 12 million bags/month per production line
- Sustainability: 22% lower carbon footprint vs. Asian competitors
