U-Channel AeroSeal™ Airtight Zipper
Engineered for Seamless Integration with Inflatable and Welded Structures.
The U-Channel Aeroseal™ is a specialized airtight zipper designed to offer both seamless integration and superior functionality in flexible applications such as bags and inflatable structures.
Its unique U-channel design makes it exceptionally adaptable around curves and corners, allowing for a smoother, more fluid motion and significantly reducing the risk of snagging or jamming. By providing a closer, more flexible fit without sacrificing airtight integrity, this zipper ensures both high performance and enhanced user convenience.
Key Feature
Integrated Weldable Flange
Wide TPU U-channel flanges allow for easy and strong HF/RF welding, creating a superior bond compared to sewing.
Monolithic Seal
Eliminates needle holes from stitching, which are potential points of leakage, resulting in a truly continuous and reliable hermetic seal.
Robust IPX7 Airtight Core
Built around our proven Standard Aeroseal™ zipper chain, guaranteeing high performance against pressure and water ingress.
Enhanced Structural Integrity
The wide welded area distributes stress more evenly across the material, increasing the overall durability of the final product.
