Wholesale Zipper Tape Roll Top Manufacturer
Our continuous zipper tape is produced as a flat coil ready for high‑speed sewing lines. The tape width, thickness, and tensile properties are controlled to within ±0.02 mm and ±2 % respectively, ensuring repeatable tooth engagement and seam strength.
Material Composition
The base fabric is typically 100 % polyester filament with a denier range of 150‑300 d, providing a balance of low elongation and high abrasion resistance. For applications requiring higher flexibility, a nylon‑6,6 blend (70 % polyester / 30 % nylon) is available, offering a 10‑15 % increase in flexibility at the cost of slightly lower UV stability.
- Polyester filament: 150‑300 d, tensile strength ≥ 45 cN/tex
- Nylon‑6,6 filament: 120‑250 d, tensile strength ≥ 38 cN/tex
- Optional cotton‑rich core (10 % cotton) for improved hand feel in apparel
Construction Specifications
Tape is slit to precise widths and wound onto polypropylene cores. The roll top edge is finished with a heat‑set selvedge to prevent fraying during unwinding.
| Parameter | Typical Value | Adjustable Range |
|---|---|---|
| Width (mm) | 20, 25, 30 | 15‑40 mm (custom) |
| Thickness (mm) | 0.18‑0.22 | 0.15‑0.30 mm |
| Core diameter (mm) | 40 | 30‑50 mm |
| Coil length (m) | 100‑200 | 50‑500 m (per customer) |
Performance Characteristics
Measured on conditioned specimens (23 °C, 50 % RH) according to ASTM D5034 for tensile strength and ASTM D3884 for abrasion resistance.
- Tensile strength: 45‑55 cN/tex (polyester), 38‑48 cN/tex (nylon blend)
- Elongation at break: 12‑18 % (polyester), 18‑24 % (nylon blend)
- Abrasion resistance (Martindale): ≥ 20 000 cycles before visible wear
- Temperature tolerance: – 20 °C to + 120 °C (continuous)
Typical Applications
In garment manufacturing, the low‑profile tape reduces bulk at seam lines while providing sufficient lateral strength to resist zipper pull‑out forces exceeding 30 N.
For luggage and travel goods, the tape’s abrasion resistance and UV‑stabilized options maintain integrity after repeated flexing and exposure to sunlight.
Industrial sewn products such as safety harnesses and automotive interior trims benefit from the tape’s temperature stability and consistent tooth engagement, which helps maintain locking force under vibration.
Quality Assurance
Each coil undergoes inline width monitoring with laser gauges (±0.01 mm) and periodic tensile testing on a 200 mm sample length.
- Width variance ≤ ±0.02 mm across the coil
- Tensile strength deviation ≤ ±3 % from target
- Visual inspection for selvedge integrity and coating uniformity
- Batch traceability via bar‑coded labels linking to raw‑material lot numbers
Customization Options
Beyond standard widths and lengths, we can adjust the tape’s surface finish and add functional coatings.
| Option | Description | Typical Impact |
|---|---|---|
| PU coating | Thin polyurethane layer (5‑10 µm) for water repellency | Adds ≈ 0.02 mm thickness, improves water resistance rating to IPX4 |
| UV stabilizer | Hindered amine light stabilizer (HALS) added to polymer melt | Retains ≥ 80 % tensile strength after 500 h UV exposure |
| Color dye | Solution‑dyed polyester for solid shades (Pantone matched) | No effect on mechanical properties; colorfastness ≥ 4 (grey scale) |
| Anti‑static additive | Quaternary ammonium compound (0.5‑1 % wt) | Surface resistivity ≤ 10⁹ Ω/sq |

Frequently Asked Questions
Can the tape width and length be customized?
Yes. Width can be adjusted from 15 mm to 40 mm in 0.5 mm increments, and coil length from 50 m to 500 m based on production capacity.
What information is required for a quotation?
Please provide desired width, length, material (polyester, nylon blend, or custom), any coating or additive, and annual volume estimate.
How is quality inspected?
Each batch is subject to laser width verification, tensile testing on five random samples, and visual selvedge inspection before packaging.
What packaging options are available?
Standard LDPE wrap on pallets; optional corrugated cardboard boxes or reusable plastic totes for clean‑room environments.
How are export shipments protected?
Pallets are strapped with polypropylene bands and corner protectors; a moisture‑barrier liner is added for sea freight.
