Aluminum Screw Caps for Wine And Spirits
Aluminum screw caps are a modern, sustainable, and versatile sealing option suitable for a variety of products including wine, spirits, and oil. They excel in maintaining product integrity, offering stylish custom designs, and ensuring consistency across different production batches.
What Are Aluminum Screw Caps?
Aluminum screw caps are metal closures that are screwed onto the necks of wine and spirit bottles. They typically include a tamper-evident band and a liner to ensure a proper seal. These caps are a modern alternative to corks and traditional closures, offering convenience, resealability, and aesthetic appeal.
Materials and Processes of Aluminum Screw Caps
- Core Material: Primarily made from 8011 aluminum alloy (especially H14 temper hot-rolled aluminum foil), which offers good ductility, strength, and corrosion resistance, suitable for bottle mouth sealing requirements.
- Structural Design: The cap includes a synthetic liner (such as PVDC material) that ensures a complete seal, while some designs allow for micro-permeability to balance the aging needs of the liquid.
- Surface Craftsmanship: Supports intricate embossing and digital printing for customized designs, enhancing brand recognition and visual appeal.
Popular Sizes of Aluminum Screw Caps for Wine and Spirits
- Various Sizes: Common diameters range from 28 to 60 millimeters, with varying lengths, suitable for wine, spirits, oils, and other liquids.
- For example, 30×60 mm is typical for spirits, while 28×44 mm is common for wine, accommodating bottles from 50 ml to 4.5 liters.

Convenience and Functionality: Easily opened without a corkscrew and can be resealed to preserve unfinished wine. Prevents issues such as cork expansion or leakage caused by temperature fluctuations. Environmental and Economic Benefits: Aluminum is 100% recyclable, aligning with sustainable development trends. Controlled production costs make it suitable for large-scale applications. User-Friendly: Easy to open and reseal; stable performance with a lower failure rate than corks. Customizable Design: Available in various colors, surface treatments, embossing, and printing techniques (offset printing, screen printing, digital printing, hot stamping, embossing)—ideal for brand promotion and premium consumption. Tamper-Evident: Many products come with detachable tamper-evident bands that indicate whether the bottle has been opened.
