Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 million, serving markets across North America, South America, Europe, Asia, and more. Our Bottle Neck Ring with PTFE Coating is engineered to deliver superior sealing performance, food safety, and durability in demanding industrial applications. With a precise 0.8mm thickness, 18mm width, and 200°C heat resistance, this product is ideal for beverage, pharmaceutical, and chemical bottle packaging where hygiene and reliability are critical.
The PTFE (polytetrafluoroethylene) coating offers exceptional non-stick properties, chemical inertness, and low friction, ensuring the ring releases cleanly from the bottle neck without contamination. Our manufacturing process uses high-grade steel as the base material, followed by a uniform PTFE coating that meets food-grade standards. This combination results in a robust, corrosion-resistant seal that maintains its integrity even under repeated thermal cycles.
