Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with annual export value exceeding US$5 million. Our 20mm PET plastic tamper-evident closure, featuring a 0.8mm wall thickness, is specifically engineered for carbonated beverages, delivering reliable sealing and tamper-proof security. Designed to withstand internal pressure while maintaining freshness, this closure is an ideal choice for bottlers seeking both safety and performance.
In the competitive beverage market, packaging integrity is paramount. Our closure combines advanced PET material technology with precision engineering to ensure that every bottle reaches consumers with its original seal intact. The 20mm neck finish is widely compatible with standard glass and PET bottles, making it a versatile solution for your production line.
Key Features & Benefits
- Tamper-Evident Design: The integrated breakable band provides clear visual evidence of opening, enhancing consumer trust and safety.
- High Pressure Resistance: With 0.8mm wall thickness, the closure withstands the internal pressure of carbonated drinks (up to 4 bar depending on bottle design), minimizing leakage risk.
- PET Material: Lightweight, recyclable, and offers excellent barrier properties against gas and moisture, preserving carbonation and flavor.
- Precision Fit: 20mm neck finish (PCO 1881 or similar) ensures a secure seal on standard bottle threads, reducing capping defects.
- Customizable Colors: Available in a wide range of colors to match your brand identity (minimum order quantity applies).
- Consistent Quality: Manufactured under strict quality control in our ISO-compliant facility (certification available upon request).

Each closure undergoes rigorous testing for torque, leakage, and tamper-evident band integrity. Our manufacturing process adheres to food-grade safety standards, ensuring that no harmful substances migrate into the beverage. The 0.8mm wall thickness not only provides strength but also contributes to consistent capping performance on high-speed filling lines.
Why Choose Our Closure for Carbonated Drinks?
Carbonated beverages require a closure that can maintain internal pressure without deformation or leakage. Our PET closure is specifically designed to meet these demands. The combination of thick walls and robust tamper-evident ring ensures that the cap remains intact even under extreme conditions. Additionally, the lightweight nature of PET reduces shipping costs and supports sustainability goals.
We offer flexible packaging options: bulk bags, cartons, or palletized loads. Lead times are typically 15–20 working days after order confirmation. Sample requests are welcome for evaluation.
Frequently Asked Questions
Q1: Is this closure suitable for hot-fill beverages?
This closure is designed for cold-fill carbonated drinks. For hot-fill applications, we recommend consulting our technical team for alternative solutions.
Q2: What is the minimum order quantity (MOQ)?
Our standard MOQ is 100,000 pieces. However, we can accommodate smaller trial orders for qualified buyers.
Q3: Can you print logos or designs on the cap?
Yes, we offer custom printing services (silk screen, hot stamping) upon request. Artwork must be provided in vector format.
Q4: How does the tamper-evident band work?
The band is attached to the cap via small bridges. When the cap is twisted open, the bridges break, leaving the band on the bottle neck as evidence of opening.
Q5: What is the typical shelf life of the closure?
When stored in a cool, dry environment away from direct sunlight, the closure maintains its properties for at least 2 years.
Q6: Do you provide third-party test reports?
Yes, we can provide test reports from accredited laboratories for material composition, pressure resistance, etc., upon request.
Q7: Can the closure be used with glass bottles?
Yes, the 20mm PCO thread is commonly used on both glass and PET bottles. Please confirm your bottle neck finish specifications.
