Leakproof Woven Bags: Multi-Layered Co-Extrusion Technology for Superior Protection

How We Achieved Zero Leakage Using 5-Layer PP/PE Co-Extrusion

Leakproof woven bags aren’t just containers—they’re your cargo’s impermeable shield. At VidePak, we’ve engineered a 5-layer co-extrusion system that blocks 100% of moisture ingress while maintaining 1,500kg load capacity. The secret? Combining Starlinger’s circular looms with AI-driven layer optimization. Let’s explore how we’re redefining moisture protection.
