VidePak’s multiwall paper bags deliver unmatched durability, with load capacities up to 2,000 kg and anti-static properties reducing electrostatic discharge risks by 98%, making them ideal for industries ranging from agriculture to construction. With ISO 9001-certified production processes and 30+ years of expertise, we ensure precision in thickness (0.5–3.0 mm), grammage (150–400 gsm), and custom sizing while maintaining ≤0.5% defect rates.
1. Technical Specifications: Thickness, Grammage, and Dimensions
Multiwall paper bags consist of 2–6 kraft paper layers bonded with adhesives, offering superior strength-to-weight ratios. VidePak’s offerings are engineered to meet diverse industrial demands:
Thickness & Grammage
- Thickness Range: 0.5–3.0 mm (measured via ISO 534 calipers), balancing flexibility and rigidity.
- Grammage: 150–400 gsm (ISO 536), with higher weights for heavy-duty applications like cement or chemicals.
Custom Sizing
| Parameter | Range | Applications |
|---|---|---|
| Bag Width | 30–120 cm | Agricultural produce |
| Bag Height | 50–200 cm | Construction aggregates |
| Valve Size | 40–100 mm | Powdered materials |
For instance, a Chilean copper concentrate supplier reduced spillage by 40% using our 3.0 mm thick, 6-layer bags with reinforced bottom gussets.
2. Anti-Static Mechanisms in Woven Bags
Static electricity poses explosion risks in flammable environments (e.g., coal dust, flour). VidePak integrates conductive materials into PP fabrics to dissipate charges:
- Conductive Yarns: Carbon-infused threads woven every 10th warp/weft strand, achieving surface resistance <10⁹ Ω (IEC 61340-4-4).
- Laminated Coatings: Anti-static PE layers (50–120 microns) block triboelectric charging.
Case Study: A Nigerian fertilizer plant eliminated electrostatic incidents using our anti-static FIBC bulk bags with 6:1 safety factors and grounding straps.
3. Load Capacity and Durability Testing
VidePak’s multiwall bags undergo rigorous stress tests:
| Test | Standard | Performance |
|---|---|---|
| Vertical Load | ASTM D5276 | 2,000 kg without rupture |
| Drop Test | ISTA 3A | 10 drops from 1.2 meters |
| Seam Strength | ISO 13934-1 | ≥80% of fabric strength |
| Moisture Resistance | ISO 2528 | <5 g/m²/24h vapor transmission |
A 2024 audit showed our bags retained 95% of initial strength after 18 months in humid storage, outperforming industry averages by 20%.
4. Customization Capabilities
Printing Precision
- Full-Surface Coverage: 8-color flexographic printing achieves 1440 dpi resolution (Pantone ΔE ≤1.5).
- UV Resistance: Inks retain 90% chromaticity after 1,500 hours (ISO 4892-3).
Structural Adaptations
- Breathable Meshes: Laser-cut vents (2–10 mm) for agricultural produce.
- Reinforced Handles: Polypropylene loops withstand 30 kg loads (EN 13590).
For example, a UAE dates exporter boosted brand visibility using our RAL 3020-red printed bags with QR codes for traceability.
5. FAQs: Addressing Procurement Concerns
Q1: What is the minimum order quantity (MOQ)?
A: MOQ starts at 5,000 units, with volume discounts for orders exceeding 50,000 bags.
Q2: How do you ensure color consistency in large batches?
A: We use X-Rite spectrophotometers and AI-driven feedback loops to maintain ΔE ≤1.5.
Q3: Are bags recyclable?
A: Yes, 100% recyclable per FSC guidelines, with 30% post-consumer recycled content.
Q4: Can bags withstand -20°C temperatures?
A: Yes, elastomer-modified adhesives retain flexibility at -25°C (ISO 4591).
