Buy Zipper Tape by the Yard Wholesale
Zipper tape forms the continuous fabric base to which interlocking teeth are attached, providing the structural backbone for slide fastener assemblies. When sourced by the yard, it allows manufacturers to cut lengths precisely to match product designs, reducing waste and enabling rapid prototyping or high‑volume production runs.
Technical Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Tape Width | 10 mm – 50 mm (customizable) | Measured edge‑to‑edge; wider tapes used for heavy‑duty applications. |
| Tooth Pitch | 3 mm – 5 mm | Distance between corresponding tooth centers; determines slider compatibility. |
| Base Material | Polyester, Nylon, Cotton‑Blend | Selected for abrasion resistance, UV stability, or flame‑retardancy. |
| Tensile Strength (MD) | ≥ 150 N/25 mm | Measured per ASTM D5034; ensures tape resists pulling forces during slider movement. |
| Temperature Range | -20 °C to +80 °C (standard) | Specialty grades available for -40 °C to +120 °C. |
| Put‑Up Length | Sold by the yard (0.914 m) increments; minimum order 100 yd | Allows precise length selection for cut‑to‑size operations. |
Material Options
- Polyester – low moisture absorption, excellent UV resistance, suitable for outdoor gear and marine applications.
- Nylon 6,6 – high tensile strength, good abrasion resistance, commonly used in automotive interiors and luggage.
- Cotton‑Blend – soft hand feel, breathable, preferred for apparel and medical textiles where skin contact is required.
- Flame‑Retardant Treated – meets UL‑94 V‑0 or similar standards, used in protective clothing and industrial safety equipment.
Typical Applications
In outdoor equipment, zipper tape made from UV‑stabilized polyester maintains closure integrity after prolonged sun exposure, preventing seam failure in tents and backpacks.
Automotive interior trim requires tape with high abrasion resistance; nylon‑based tapes withstand repeated flexing of door panels and seat covers without premature wear.
Medical gowns and sterile packaging benefit from cotton‑blend tapes that can be sterilized via autoclave while retaining softness and low lint generation.
Flame‑retardant tapes are essential in firefighter turnout gear, where the fastener must remain functional after exposure to radiant heat and direct flame contact.
Customization Choices
- Width adjustment from 10 mm to 50 mm in 2 mm increments.
- Tooth profile selection (standard, concealed, waterproof) to match slider type.
- Color matching using Pantone or custom dye lots for brand consistency.
- Edge finishes: sealed, heat‑cut, or ultrasonic to prevent fraying.
- Add‑on treatments: antimicrobial, anti‑static, or water‑repellent coatings.
Quality Control Philosophy
Each production lot undergoes tensile testing on a sample length of tape to verify that the longitudinal strength exceeds the specified minimum, ensuring the tape will not elongate under normal slider load.
Visual inspection under standardized lighting checks for consistent weave density, absence of broken filaments, and uniform edge quality, which directly influences slider alignment and tooth engagement.
Dimensional stability is assessed by measuring width and thickness after exposure to defined humidity and temperature cycles; acceptable variation is limited to ±0.2 mm to guarantee repeatable cut lengths.
Packaging & Shipping
- Tape is wound on reusable plastic cores with inner diameter 25 mm, outer diameter 150 mm.
- Each yard length is marked with a perforated tear tape for easy length identification.
- Palletized shipments use stretch film and corner boards to protect against moisture and mechanical damage during transit.
- Export containers include desiccant packs and are lined with vapor barrier tape when humidity‑sensitive grades are shipped.
Frequently Asked Questions
Yes. Width is adjusted during weaving to match the slider’s tooth width; provide the slider model or tooth pitch for a precise quote.
What information is needed before a quotation?Desired width, material type, length per roll (yard increments), any special treatments (e.g., flame‑retardant, UV‑stabilized), and annual volume.
How is tape quality verified?Through tensile strength testing, dimensional stability checks, and visual inspection per internal standards aligned with ASTM and ISO textile test methods.
What packaging options exist for long‑length orders?Standard cores, custom‑length spools, or bulk‑packed rolls with interleaving sheets to prevent adhesion between layers.
