In the liquor packaging system, aluminum bottle caps are not only a core component ensuring the sealing and flavor stability of the wine, but also the primary carrier of brand visual presentation. Their material quality directly determines production efficiency, product compliance, and the end-consumer experience. As a professional manufacturer specializing in aluminum exports, Haomei Aluminum offers a full range of aluminum sheets specifically designed for liquor bottle caps to meet the diverse production needs of global wine customers. With precise material formulations, stable processing performance, and a comprehensive compliance system, these aluminium sheets are suitable for various liquor packaging scenarios.

Material selection that aligns with the bottle cap manufacturing process is the core foundation of product adaptability. Our aluminum sheets for liquor bottle caps are primarily selected from 8011 and 3105 alloys, covering mainstream industry application needs:

8011 aluminum-iron-silicon alloy, available in H14 and H16 tempers, combines moderate strength with excellent ductility, suitable for deep drawing of most temper-evident caps for liquor and ROPP caps for wine;

3105 alloy offers higher structural strength and deformation resistance, specifically designed for pressure-resistant bottle caps for beer, champagne, and other carbonated beverages.

Product thickness covers the mainstream range of 0.18-0.25mm, with thickness tolerance strictly controlled within ±0.005mm. Width can be customized according to customer stamping equipment. All dimensional indicators comply with the YS/T 91-2009 industry standard, compatible with various high-speed cap-making production lines worldwide.

To meet the high-speed stamping requirements of liquor bottle cap production, we optimize the composition and control the graded annealing process to consistently maintain the yield within 2%. Deep drawing results in crack-free and wrinkle-free deep-drawing with high edge neatness, significantly reducing stamping waste and making it suitable for automated production lines producing hundreds of pieces per minute. Regarding safety requirements for wine contact, the aluminum closure sheet for wine bottle caps feature a food-grade coating system with adhesion reaching level 0 in the cross-cut test. It is resistant to long-term immersion in alcohol and weak acids without peeling, and aluminum ion migration meets US FDA and EU DGCCRF standards for food contact materials, eliminating the risk of liquor contamination at the source. Simultaneously, the plate undergoes precision bending and straightening, resulting in a smooth surface free of pinholes and oil stains, perfectly adaptable to various surface treatments such as roller coating, hot stamping, and embossing, accurately reproducing brand logo details.

Haomei Aluminum's core export advantage lies in its end-to-end guarantee for global wine customers. We have established a full-process quality traceability system, controlling the tensile strength deviation of products within the same batch to within 5%, with batch consistency far exceeding the industry average, ensuring long-term production stability for our customers. For export needs, we can provide a full set of multilingual testing reports and compliance certification documents to help clients quickly gain access to local markets. We also support small-batch customization, adjusting alloy conditions, coating formulations, and dimensions according to the client's bottle cap structure, with stable and controllable delivery cycles.

Currently, Haomei Aluminum's aluminum sheets for liquor bottle caps are widely used in all categories of alcoholic beverage packaging, including anti-theft caps for baijiu, roll-on caps for wine, crown caps for beer, screw caps for spirits, and combination caps for health tonics. Our products are exported to dozens of countries and regions in Europe, Southeast Asia, and North America, making us a stable supplier for many international alcoholic beverage brands and packaging companies. We always focus on material technology, continuously optimizing product performance to provide reliable aluminum solutions for the global alcoholic beverage packaging industry.
