Form · Finished / Chain

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.

TZ Finished ( TZ )

TZFinished ( TZ )

Cut to your requested inner length, ends sealed, ready to sew in.

MZ Chain by meter ( MZ )

MZChain by meter ( MZ )

Continuous chain supplied by the meter; the end-slot stays blank in the code.

Coating Method

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.

S Single-face coated ( S )

SSingle-face coated ( S )

One face coated; lighter and more flexible.

D Double-face coated ( D )

DDouble-face coated ( D )

Both faces coated for maximum abrasion life.

Material

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.

TPU TPU

TPUTPU

Default choice: weldable, elastic, low-temperature stable.

PVC PVC

PVCPVC

Alternative for specific cost or solvent-weld specifications.

Slider

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.

Color

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.

K Black ( default )
