- Q: What is the benefit of a UN-certified box for liquids?
- A: A UN-certified box (e.g., 4G Fibreboard) has been tested to withstand specific drop heights and stacking loads with the inner liquid container, providing legally recognized security.
- Q: How is HVLD testing performed on the bags?
- A: HVLD (High Voltage Leak Detection) passes a high voltage electrical charge over the surface of a filled bag. Any pinhole or micro-leak creates a conduction path, which is automatically detected, ensuring ultimate seal integrity.
Structural Components
- Primary Liner: Heavy-gauge co-extruded film with double seams.
- Fitment Seal: Welded gland with secondary heat seal or gasket.
- Secondary Barrier: Inner liner or casing of absorption material.
- Outer Casing: UN-rated double or triple wall corrugated box with internal cushioning.
Material & Assembly Process
Materials: Chemical-resistant Nylon/EVOH/PE laminates, High Strength Adhesives, and UN-Grade Fiberboard. Process: Automated bag forming using **dual sealing bars** to create redundant seams, followed by in-line pressure testing.
