Eight-Thread Explosion-Proof Double-Layer Zipper

Extra seam coverage for longer life under repeated heavy use.

The #8 eight-thread model is a medium-heavy profile for frequent opening under load. High-density four-needle eight-thread sewing creates more attachment points between the tape and chain base than the six-thread construction. Dual-layer, dual-track polyester coil teeth share pressure during bag expansion, stacking, and repeated transport, while the flexible chain remains suitable for washing and cyclic reuse.

Key Features

  • Four-needle eight-thread high-density stitching
  • Larger seam area with more stress points
  • Dual-layer dual-track explosion-proof structure
  • Stable performance after multiple industrial washes
