SPIFR #3 Plastic Fire Retardant Closed-End Zipper

Focused on bulk procurement needs in light industry and commercial service scenarios, this Size 3 plastic flame-retardant closed-end zipper centers on "lab-grade safety + bulk compatibility". With a stable and durable closed-end structure, it balances cost and performance, becoming a cost-effective supporting component for commercial workwear and bulk bedding.

Safety Compliance Backed by Testing (Core Procurement Guarantee)

• Flame Retardancy: No ignition or molten dripping, 0-second after-flame time, complying with "non-flammable/non-melting" commercial flame-retardant standards.
• Structural Integrity: No cracking of the closed-end bottom box or tooth detachment; the zipper retains 100% functionality, withstanding frequent opening/closing in bulk use.
• Damage Control: Char length is only 3mm (far below the industry threshold of ≤100mm), resulting in extremely low product loss rate and reducing hidden costs of bulk procurement.

Core Commercial Advantages of Closed-End Structure

• Bulk Production Compatibility:
  • Workwear: Suitable for catering chain uniforms, cleaning company protective jackets, and mall service staff attire. The stable closed-end structure resists damage after daily wear, removal, and washing, reducing the frequency of corporate workwear replacement.
  • Bedding: Fits hotel flame-retardant bedding (pillowcases, duvet covers), nursing home care bedding, and hospital accompanying bed sheets. The closed-end design prevents accidental zipper slipping during use, enhancing user experience.
  • Commercial Equipment: Compatible with commercial cleaning tool bags, hotel linen storage bags, and catering industry material bags. The sealed closed-end structure protects internal items from dust and stains.

Durability and Compatibility in Commercial Scenarios

• Reinforced Material Design: Teeth made of high-strength engineering plastic with anti-aging additives, resisting embrittlement and breakage during long-term use. 
• Adaptability to Harsh Environments: Resistant to moisture and regular detergent corrosion, maintaining flame-retardant performance and structural stability after repeated washing in hotel laundries and industrial cleaning workshops. No metal components—rust-free and oxidation-free, suitable for long-term use in humid environments.

Risk Mitigation and Value Empowerment for Buyers

• Compliance Guarantee: Test report copies are available per batch, supporting third-party re-inspection by buyers to ensure product compliance with commercial safety audit requirements, avoiding order losses due to non-compliant safety.
• Brand Endorsement: Test reports can be displayed on commercial product pages to strengthen the buyer’s "safe and professional" brand image, enhancing end-customer trust.
• After-Sales Support: 1-year quality guarantee with free replacement for non-human zipper failures. A professional technical team provides sewing guidance to solve compatibility issues in bulk production.
