Why Double-Layer Reinforced Seam Technology Matters？
In demanding industrial liquid containment scenarios, the seam is the first line of defense. Standard manufacturing often relies on a single weld, which can be a point of failure under high pressure. At Bancy, we produce superior reinforced flexible tanks by re-engineering this vulnerability.
Single welds are susceptible to peel forces and high pressure.
Double-layer technology creates structural redundancy, significantly reducing failure risks.
Precision Through Hybrid Manufacturing
Expert Hot Air Precision
The backbone of our production. Our skilled technicians utilize professional Hot Air Welding tools to create the primary seams. With years of experience, they ensure consistent temperature and pressure control over long distances, creating a flawless base for reinforcement.
Double Layer, Double Security
After the primary weld, we apply a secondary reinforcement strip. This structural upgrade increases tensile strength by 30%, virtually eliminating the risk of seam bursting.
Detail-Oriented HF Precision
For complex geometries like valves and flanges, we use High-Frequency (HF) Welding. This ensures intricate connection points are fused into a solid, leak-proof unit.

How We Test Our Double-Layer Reinforced Seam Technology
Tensile Strength Test
We test weld samples to destruction. Our Double-Weld technology ensures that the parent material will typically fail before the reinforced seam separates.
Air Pressure Test
Before packaging, tanks undergo a rigorous air inflation inspection to verify seam tightness. This crucial step ensures structural integrity and eliminates manufacturing defects prior to shipment.
Puncture & Abrasion
Our industrial-grade TPU/PVC fabrics are rigorously tested against abrasion and sharp objects, ensuring the tank survives rough handling and rocky ground deployment.
