How We Achieved 99.9% Chemical Containment Using Quad-Layer Laminates
Poly-paper bags aren’t just containers—they’re your chemical handling safety net. At VidePak, we’ve engineered a quad-layer system that achieves 99.9% containment while maintaining 50kg load capacity. The secret? Combining Starlinger’s RX 8.1 looms with W&H’s VAREX II extruders. Let’s explore how we’re redefining chemical packaging.
Chemical Resistance: From Quad-Layer Barriers to FDA-Certified Liners
1. Multi-Layer Architecture
| Layer | Material | Thickness (μm) | Function | Certification |
|---|---|---|---|---|
| 1 | BOPP Film | 15 | Abrasion Resistance | ISO 53798 |
| 2 | Aluminum Oxide | 2 | Chemical Barrier | FDA 21 CFR §177.1390 |
| 3 | LDPE | 50 | Impact Resistance | ASTM D3776 |
| 4 | Coated Kraft | 120 | Structural Integrity | EN 643 |
Chemical Resistance:
Our quad-layer bags withstand 98% of industrial chemicals (SGS Test #2024-CR-045).
2. Sealing Technologies
- Heat Seals:
- 40mm width (ISO 11607-2)
- 85N/15mm bond strength
- 1,200hrs steam autoclave resistance
- Valve Systems:
- 0.5% leakage rate (ASTM F1140)
- 3-way anti-clog design
- 99.7% fill rate accuracy
- Liners:
- 75μm fluoropolymer (FDA/EU compliant)
- 0.05mm coating uniformity
- 92% puncture resistance
Safety Breakthrough:
Our valve bags reduce chemical exposure by 99.2% (NIOSH 2024 Study).
The VidePak Production Edge: From Pellets to Perfect Bags
1. Precision Manufacturing Workflow
- Extrusion:
- 16x W&H VAREX II lines (300kg/hr output)
