Poly Fabric Bags: Engineering Excellence Through Rigorous Testing Protocols

The Moisture Ingress Crisis: How 58% of Product Degradation Occurs During Transit

In an era where 58% of product degradation happens during transportation (Packaging Digest 2024), Poly Fabric Bags have emerged as critical barriers against environmental hazards. At VidePak, we’ve engineered these solutions to achieve 99.4% moisture barrier performance through our proprietary 9-layer defense system. Our 568-strong team, averaging 19 years of packaging engineering experience, operates at the material science frontier, creating poly fabric solutions that exceed ASTM D7709 standards across 27 critical performance metrics.
