Products Details
Product Feature
1. Premium Material
This zinc alloy polymer bottle stopper features an innovative composite structure design, with the top made from high-quality zinc alloy material. It undergoes precision casting and multiple polishing processes to achieve the distinctive premium metallic texture characteristic of zinc alloy. The zinc alloy component can be finished with PVD vacuum coating (gold/silver/rose gold), antique patina, or mirror polishing. The stopper body is made from food-grade polymer material, offering excellent chemical stability and elastic memory functionality.
2. Sealing Technology
The product features an ergonomic conical design combined with a precision internal thread structure to achieve three levels of sealing protection: the first level is a high-molecular plug that fits tightly into the bottle opening, and the second level is an internal silicone seal that effectively blocks oxygen penetration, making it particularly suitable for long-term storage of high-end spirits. The zinc alloy counterweight design makes opening and closing smoother and more fluid, and the recessed design at the top makes it easy to operate with one hand.
3. customised services
We offer comprehensive customised solutions: in terms of appearance, we support laser micro-engraving (minimum precision of 0.1 mm), 3D relief embossing, colour transfer printing and other processes; sizes can be adapted to international standards such as 28 mm and 38 mm, or we can develop custom sizes based on bottle samples provided by customers. From design and prototyping to mass production, professional engineers provide technical support throughout the entire process to ensure that every detail is in line with the brand's style.
4. Sustainable Philosophy
This bottle stopper has become the packaging of choice for many luxury alcoholic beverages, particularly high-end products such as spirits and whisky. Its exceptional sealing performance ensures that the liquid remains in optimal condition for up to 20 years of ageing, while its metallic appearance significantly enhances the product's prestige. Whether upgrading existing product lines or developing new categories, this is a strategic packaging solution that can immediately enhance brand value.
