#8GS-SZ8-FB-PET-DC-8#
Grooved Eight-Thread Explosion-Proof Zipper
A shielded track keeps every seam aligned through harsh handling.
The #8 grooved eight-thread model is designed for large logistics bags, trolley cases, and industrial fabric packaging. An integrated groove in the tape positions the eight stitching lines and separates them from direct slider friction. Four-needle eight-thread sewing and dual-layer, dual-track polyester coil teeth improve seam alignment, flatness, and load distribution through repeated handling and cleaning.
Key Features
- ✓Integrated groove protects stitching from wear
- ✓Eight-thread edge lock prevents tearing
- ✓Double-layer teeth resist burst and chain separation
