As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Plastic Tamper Evident Closure Ring with a 22mm bore and 1.2mm thickness. Designed to provide reliable security and product integrity, this ring features high tear strength and UV resistance, making it an ideal choice for industries requiring tamper-proof packaging. Our factory, located in Hengshui, Hebei, China, has exported over US$5 million annually to global markets, including North America, Europe, and Southeast Asia. We combine decades of experience with modern production techniques to deliver consistent quality and performance.
The 22mm bore is precisely engineered to fit standard bottle necks and closures, while the 1.2mm thickness ensures optimal balance between flexibility and durability. The tamper-evident design breaks upon first opening, providing clear visual evidence of tampering. This ring is made from a specially formulated plastic compound that resists UV degradation, maintaining its mechanical properties even under prolonged sunlight exposure. Below are key technical specifications:
| Parameter | Value |
|---|---|
| Bore Diameter | 22 mm ± 0.2 mm |
| Thickness | 1.2 mm ± 0.1 mm |
| Tear Strength | High (tested per ASTM D1004) |
| UV Resistance | >500 hours (accelerated aging) |
| Operating Temperature | -20°C to 60°C |
| Color Options | Transparent, White, Blue, Red, Green (custom colors available) |
Key features and benefits:
- Tamper Evident Design: The ring incorporates a breakable bridge that fractures irreversibly when the cap is first removed, ensuring product integrity from factory to consumer.
- High Tear Strength: Engineered with advanced polymer blends, the ring resists accidental tearing during handling and transportation, reducing the risk of false tamper indications.
- UV Resistant Formulation: Special additives protect the plastic from ultraviolet radiation, preventing embrittlement, discoloration, and loss of mechanical strength over time. Ideal for outdoor storage or sun-exposed products.
- Precision 22mm Bore: Manufactured to tight tolerances, the ring fits securely onto standard 22mm bottle necks, providing a snug, wobble-free fit that enhances tamper evidence.
- 1.2mm Thickness Balance: This thickness provides sufficient rigidity for the tamper-evident mechanism while remaining flexible enough for easy application without cracking.
- Versatile Application: Suitable for use on beverage bottles, pharmaceutical containers, chemical packaging, and other products where tamper protection is required.
- Cost-Effective Security: Compared to metal or complex locking systems, this plastic ring offers a low-cost yet highly effective tamper-evident solution.

Frequently Asked Questions (FAQ)
-
Q: What material is the tamper evident ring made of?
A: Our ring is manufactured from a high-density polyethylene (HDPE) compound, which offers excellent tear strength and UV resistance. The specific formulation can be customized based on your application requirements. -
Q: Can the bore diameter be made larger or smaller than 22mm?
A: Yes, we offer customization options. The 22mm is our standard size, but we can produce rings with bore diameters ranging from 18mm to 30mm. Please provide your exact specifications. -
Q: What is the typical shelf life of the UV resistance?
A: Under normal indoor storage conditions, the UV resistance remains effective for at least 5 years. For outdoor exposure, we recommend conducting accelerated aging tests as per your expected usage; our formulation withstands over 500 hours in a UV chamber without significant degradation. -
Q: How does the tamper evidence work?
A: The ring has a series of thin bridges (usually 2–4) connecting the ring to the cap. When the cap is twisted open, these bridges break, leaving a visible gap that indicates the package has been opened. Once broken, the ring cannot be restored. -
Q: Is the ring food-grade safe?
A: Our standard material is food-grade approved and complies with general food contact regulations. If you require specific certifications (e.g., FDA, EU), we can provide materials that meet those standards upon request. Please note that final compliance depends on the entire packaging system. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, the MOQ is 100,000 pieces. For customized sizes or colors, the MOQ may be higher. We can also negotiate smaller trial orders for new customers. Contact us for details. -
Q: How are the rings packed for shipment?
A: Rings are packaged in bulk in polypropylene bags, then placed in strong export cartons or pallets as per your preference. We can also provide custom packaging with your logo if needed. -
Q: What is the lead time for production?
A: For existing tooling (standard 22mm), lead time is typically 15–20 days after order confirmation. For new molds, please add 30–45 days for tooling development.
