As a leading manufacturer with over 26 years of experience (since 1998), Anping County Boli Hardware Wiremesh Products Factory is proud to introduce our PP Plastic Bottle Clasp with Neck Ring – a precision injection-molded component designed for reliable bottle closure and handling. This 28mm diameter clasp, weighing only 2.5g, combines lightweight efficiency with robust performance, making it an ideal choice for packaging in the beverage, cosmetic, and chemical industries. Our product is engineered to meet the demands of global markets, with annual exports reaching US$5–10 million across North America, Europe, Southeast Asia, and beyond. We prioritize quality and consistency, ensuring every clasp delivers a secure fit and long-lasting durability.
The 28mm neck ring design allows for seamless integration with standard bottle necks, providing a tight grip that prevents leakage or accidental opening. Unlike traditional metal or rubber clasps, our PP version offers excellent chemical resistance, low moisture absorption, and is fully recyclable. The injection molding process ensures precise dimensions and a smooth surface finish, reducing friction during assembly and enhancing user experience. Whether you need a tamper-evident seal, a carrying handle, or a simple locking mechanism, this clasp can be customized to suit your specific requirements. We offer a wide range of color options and can tailor the design to match your branding or functional needs.
Key Features & Technical Benefits:
- High-Quality Polypropylene (PP) Material: Lightweight (2.5g) yet strong, with excellent impact resistance and fatigue life. Suitable for repeated use without cracking.
- Precision 28mm Diameter: Engineered to fit standard bottle necks (28mm nominal diameter) with a tolerance of ±0.1mm, ensuring a snug and secure fit.
- Injection Molded for Consistency: Each clasp is produced under strict quality control, with uniform thickness and no flash or burrs. This reduces assembly downtime and improves production efficiency.
- Versatile Neck Ring Design: The integrated neck ring acts as a locking mechanism, preventing the clasp from sliding off. It can also serve as a carrying loop or tamper-evident feature.
- Customizable Colors & Finishes: Available in standard white, transparent, or any Pantone color. UV-resistant and food-grade options are available upon request.
- Eco-Friendly & Recyclable: PP is a widely recyclable plastic, supporting sustainable packaging initiatives.
- Application Flexibility: Ideal for water bottles, juice containers, cosmetic bottles, household chemicals, and industrial packaging.

Our PP Plastic Bottle Clasp offers significant advantages over alternative solutions. Compared to metal springs or rubber bands, it provides a more consistent clamping force, is resistant to corrosion, and does not rust. The lightweight design reduces shipping costs and minimizes the overall weight of the final product. Additionally, the injection molding process allows for intricate features such as finger grips, vent holes, or tamper-evident tongues to be incorporated directly into the mold, eliminating secondary operations. This translates to faster production cycles and lower total cost of ownership for our clients.
