#8 Airtight Zipper

Custom Your Zipper
Choose how the zipper reaches your production line — as finished zippers cut to your inner length, or as chain by the meter for your own cutting and splicing plan.

TZFinished ( TZ )
Cut to your requested inner length, ends sealed, ready to sew in.
MZChain by meter ( MZ )
Continuous chain supplied by the meter; the end-slot stays blank in the code.
The protective layer is laminated onto the woven tape. Single-face keeps one side film-free; double-face is the heavy-duty choice for abrasion and repeated wash-downs.
SSingle-face coated ( S )
One face coated; lighter and more flexible.
DDouble-face coated ( D )
Both faces coated for maximum abrasion life.
Two choices: TPU as the default, or PVC for specific cost and welding specifications. Tell us your welding process and we will match the right one.

TPUTPU
Default choice: weldable, elastic, low-temperature stable.
PVCPVC
Alternative for specific cost or solvent-weld specifications.
Industrial-grade sliders matched to gauge and duty; logo printing or custom injection pullers available for brand identity.
⚠ Z Auto-lock: NOT available for airtight zippers — garment zippers only; final specs to be verified with engineering.
Black is the default: matte, gloss or matte-gloss finish. Colored zippers are dyed to your Pantone. Color-woven needs no dyeing at all — the colored yarn is woven straight into the tape, so the pattern survives abrasion.
KBlack ( default )
Matte / gloss / matte-gloss film finish — stocked, fastest lead time.

CColored ( dyed to Pantone )
Tape dyed to your Pantone number for brand matching.
WColor-woven ( no dyeing )
Colored yarn woven straight into the tape — the pattern survives abrasion, no dye batch needed.
