Due to its excellent stretchability, stable performance, and smooth surface, 3105 aluminum alloy is highly suitable for manufacturing wine bottle caps and other packaging materials. In addition, 3105 aluminum alloy provides excellent sealing properties and tensile strength, offering great protection to the wine inside the bottle. Furthermore, this alloy is environmentally friendly, recyclable, and meets the sustainable development requirements of the modern packaging industry.

3105 Aluminum Coil Characteristics

3105 aluminum coil has good rust resistance, excellent conductivity (up to 41%), and is highly plastic in its annealed state. It retains good plasticity during semi-cold working, but its plasticity decreases as cold work hardens it. It also has excellent corrosion resistance, good weldability, and average machinability.

Typical 3105 Aluminum Alloy Specifications

3105 Aluminum Sealing Caps for Wine: Features

1.Corrosion Resistance
3105 aluminum alloy offers exceptional corrosion resistance in humid and fluctuating temperatures, especially under the influence of acids and moisture. This ensures that the cap will not degrade or affect the wine’s quality.

2.Lightweight and Durable
While 3105 aluminum alloy is lightweight, it is also tough and durable, ensuring a secure seal while reducing the overall weight of the bottle, which is important for transportation and handling. It helps preserve the freshness and flavor of the wine.

3.Ease of Manufacture and Customization
The high workability of 3105 aluminum alloy allows manufacturers to easily shape and mold it into precise, aesthetically pleasing bottle caps. It also supports embossing, branding, and other customization options, making it ideal for premium wine packaging.

4.Sustainability
Aluminum is one of the most recyclable materials available, and using 3105 aluminum alloy for bottle caps enhances sustainability efforts. It meets the growing consumer demand for eco-friendly packaging.

5.Non-Reactivity
3105 aluminum alloy does not react with the wine, ensuring that the taste or aroma of the wine remains unchanged. It is perfect for preserving the integrity of high-quality red wines.

Advantages Over Traditional Plastic Bottle Caps

Compared to traditional plastic bottle caps, aluminum alloy bottle cap materials offer better sealing, with no leaks. When paired with an aluminum foil PE liner, the oxygen permeability is reduced, and water permeability is minimized. Additionally, 3105 aluminum alloy allows for extensive printing, multi-color designs, and embossing on the sides, offering more design space and excellent color saturation. The high gloss finish provides a premium look. Moreover, it is cost-effective, food-safe, and recyclable, making aluminum anti-theft bottle cap material an advantageous choice for anti-counterfeit packaging.
