Imagine a logistics manager at a chemical plant asking, “How can we prevent costly leaks during overseas shipments of titanium dioxide powder?” The answer lies in three pillars: precision-engineered PE liners, customizable anti-static solutions, and load-bearing capacities up to 1,500 kg. VidePak’s woven bags reduce leakage incidents by 99%, dissipate electrostatic risks, and withstand extreme handling—ensuring compliance with global standards like UN 4G/X and EU REACH.
1. Engineering Leakproof Excellence: The Role of PE Inner Liners
Polyethylene (PE) liners are the cornerstone of leakproof woven bags, offering unmatched protection for fine powders, granules, and liquids. Here’s how they work:
1.1 Material Specifications and Performance
- Thickness Range: 0.05–0.15 mm, tailored to cargo abrasiveness (e.g., 0.10 mm for silica gel, 0.15 mm for calcium carbonate).
- Seam Integrity: Heat-sealed at 150–180°C, achieving peel strength >25 N/25mm (tested per ASTM F88).
A 2023 study by the Flexible Packaging Association found that PE-lined bags reduced leakage rates from 8% to 0.3% in chemical logistics.
2. Customization Through Advanced Parameter Control
VidePak’s bags are engineered to meet diverse industrial needs:
2.1 Product Dimensions and Weight Capacity
| Parameter | Range | Application Example |
|---|---|---|
| Bag Size | 20 cm × 30 cm to 120 cm × 180 cm | 25 kg fertilizer, 1,000 kg FIBC |
| Fabric GSM | 80–200 GSM | 80 GSM for grains, 200 GSM for sharp minerals |
| Load Capacity | 10–1,500 kg | 50 kg cement, 1-ton bulk chemicals |
2.2 Anti-Static Technology: Safeguarding Hazardous Cargo
- Conductive Fibers: Carbon-coated PP yarns reduce surface resistivity to 10⁶–10⁸ Ω/sq (per IEC 61340), preventing sparks in flammable environments.
- Dissipation Mechanism: Static charges are grounded via copper threads woven into seams, compliant with ATEX Directive 2014/34/EU.
For instance, a client shipping lithium-ion battery materials achieved zero electrostatic incidents after switching to VidePak’s anti-static bags.
3. Quality Assurance: VidePak’s 15-Point Inspection Protocol
Every bag undergoes rigorous testing to ensure reliability:
3.1 Critical Tests and Standards
- Tensile Strength: ≥40 N/mm² (MD) and ≥30 N/mm² (TD) per ASTM D5034.
- Abrasion Resistance: 5,000+ cycles on Taber Abraser (ISO 5470-1).
- UV Stability: <5% strength loss after 1,000 hrs in QUV chamber (ASTM G154).
3.2 Case Study: Optimizing Cement Packaging in Nigeria
A construction firm using VidePak’s 140 GSM PE-lined bags reported:
- Leakage Reduction: From 12% to 0.5% in high-humidity environments.
- ROI: Saved $45,000/year in product loss and cleanup costs.
4. VidePak’s Manufacturing Mastery
Founded in 2008 by CEO Ray Chiang, VidePak combines 30+ years of expertise with cutting-edge technology:
- Production Scale: 100+ Starlinger circular looms, 30 lamination machines, and 16 extrusion lines enable 12,000 MT/month output.
- Customization: Multi-layer printing (up to 8 Pantone colors), FIBC compatibility, and FDA-approved liners for food-grade applications.
5. FAQs: Addressing Client Concerns
Q1: How do I choose between 0.10 mm and 0.15 mm PE liners?
A: 0.10 mm suits non-abrasive powders (e.g., flour), while 0.15 mm is ideal for sharp materials like quartz sand.
Q2: Are your anti-static bags certified for lithium battery transport?
A: Yes. Our bags meet UN 38.3 and IEC 62281 standards for lithium battery safety.
Q3: What’s the maximum pallet height for 50 kg bags?
A: 8 meters (26 ft) when using our 200 GSM fabric with double-stitched seams.
