Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, presents our Plastic Bottle Clasp with Neck Ring — a reliable solution for cosmetic bottle sealing that combines moisture-proof protection and tamper-evident design. With over 25 years of experience in precision manufacturing and an annual export value between US$5 million and US$10 million, we deliver products that meet global standards for quality and safety. This clasp is engineered to preserve product integrity, extend shelf life, and provide visible evidence of any unauthorized opening — essential for cosmetics and personal care brands.
Key Features & Technical Specifications
- Dual-Protection Design: The integrated neck ring and clasp mechanism create a secure seal that prevents moisture ingress and acts as a tamper-evident indicator — once opened, the clasp breaks or leaves a visible mark, ensuring consumer confidence.
- High-Quality Material: Made from food-grade, BPA-free HDPE or PP plastic, the clasp is resistant to chemical corrosion, lightweight, and durable, suitable for various cosmetic formulations including lotions, serums, and sprays.
- Perfect Fit for Standard Bottles: Designed to fit common neck sizes (18mm, 20mm, 24mm, 28mm) with precise tolerances, ensuring a snug and leak-proof closure without the need for additional adhesives.
- Customizable Options: Available in a range of colors (white, black, transparent, or custom Pantone) and can be hot-stamped or pad-printed with your brand logo for professional packaging.
- Easy Assembly: The clasp can be quickly snapped onto the bottle neck manually or with automated capping equipment, reducing production line downtime.

Frequently Asked Questions (FAQ)
-
Q: Can this clasp be used with bottles that have a pump or spray nozzle?
A: Yes, our clasp is designed to fit over the neck of standard cosmetic bottles, including those with pumps or spray heads. The neck ring sits securely below the pump threads, and the clasp seals the area around the neck to prevent moisture ingress. -
Q: Is the clasp reusable after opening?
A: The tamper-evident design is intended for one-time use — once the clasp is broken or removed, it cannot be reapplied securely. This ensures that any tampering is immediately visible. -
Q: Do you offer custom colors and logo printing?
A: Absolutely. We can match any Pantone color and apply custom logos via hot stamping or pad printing. Minimum order quantity for custom printing is 50,000 pieces. -
Q: What is the minimum order quantity for standard colors?
A: For standard colors (white, black, transparent), the MOQ is 10,000 pieces per size. For custom colors, the MOQ is 30,000 pieces. -
Q: How do I know which size fits my bottle?
A: Measure the outer diameter of your bottle neck (the threaded part). Our clasp is available for 18mm, 20mm, 24mm, and 28mm diameters. If you need a different size, please contact us for custom tooling. -
Q: Can you provide samples before bulk order?
A: Yes, we offer free samples (you pay shipping cost) for standard sizes. Custom samples are available with a small tooling fee. Lead time for samples is 3–5 working days. -
Q: Is the material safe for contact with cosmetics?
A: Yes, we use food-grade HDPE or PP that is BPA-free and compliant with FDA and EU regulations for cosmetic packaging. Material certificates can be provided upon request. -
Q: How long is the production lead time for a bulk order?
A: For standard sizes and colors, production takes 15–20 days after order confirmation. For custom sizes or colors, please allow 25–30 days including tooling time.
