When Sustainability Meets Strength: The New Packaging Paradigm
Sewn open mouth PP bags are quietly revolutionizing global supply chains. At VidePak, we’ve spent 17 years perfecting these bags to carry 50–100 kg loads while being 100% recyclable—a rare combo in an industry where 68% of packaging ends up in landfills. Our secret? A $58 million automation ecosystem that weaves, prints, and seals 1.5 million bags monthly with defect rates below 0.3%.
Customization: The Anatomy of a Tailored Solution
1. Valve Engineering: Precision for Powders, Pellets, and Beyond
- Spouted Valves: Adjustable 50–150 mm diameters for cement discharge control.
- Pinch-Bottom Design: 98% dust containment verified by ASTM D7490 testing.
Client ROI Story:
When a UAE cement producer struggled with 22% material waste, we engineered anti-clogging valves with 12-micron LDPE liners. Result? Zero cement hardening in 50°C desert conditions and $420,000 annual savings.
2. Handle Innovation: Where Ergonomics Meets Endurance
- Die-Cut Grips: 50 kg load capacity with 200 N tensile strength (ISO 2813).
- Reinforced Zones: 300% tear resistance via double-stitched PP webbing.
Engineering Insight:
Our Starlinger HD1200 looms integrate handles during weaving—a process that slashes labor costs by 45% compared to traditional post-production attachments.
3. Shape Shifting: From Conical to Custom
- Tapered Bags: 45° angles for 20% better pallet density.
- Modular Designs: Convertible between 25 kg sacks and 1-ton bulk containers.
Testing Edge:
- Drop Resistance: Survives 1.8-meter falls with <5% deformation (ISO 2248).

Equipment Excellence: The Starlinger and W&H Advantage
VidePak’s machinery park isn’t just advanced—it’s strategically lethal:
1. Starlinger viscotec Extruders
- Line Speed: 400 meters/minute—faster than a cheetah’s top sprint.
- Energy Savings: 45% lower consumption via regenerative braking.
- Accuracy: 0.3mm thickness control via laser gauges.
Fun Fact: These extruders produce 2.4-meter-wide films with ±1% thickness tolerance—critical for flawless multi-panel prints.
2. W&H FlexoPrinting Lines
- Resolution: 180 lines/inch—sharp enough to print a human hair’s width.
- Color Magic: 10-color system with Pantone matching (ΔE <0.5).
- Changeover Speed: <8 minutes via servo-driven unwinders.
VidePak Innovation:
Our AI-driven color calibration reduces setup waste by 60% compared to manual methods.
3. Starlinger HD1200 Looms
- RPM: 1,300 cycles/minute with 0.2% defect rate.
- Automation: Self-optimizing mode adjusts weave density based on humidity sensors.
- Output: 1.5 million bags/month per line.
Engineering Insight:
These looms’ “zero-defect” mode uses 12 cameras to inspect every millimeter of fabric—a feature that reduced customer complaints by 75%.
Application Matrix: Industry-Specific Solutions
| Sector | Recommended Bag Type | Key Features | Compliance Standards |
|---|---|---|---|
| Agriculture | UV-Stabilized Open Mouth Bags | 18-month outdoor durability | ISO 8191 (lightfastness) |
