Different cap colors can be selected to coordinate with bottle colors, labels and overall brand design.

Available in 18/410, 20/410, 24/410 and 28/410

Choosing the correct neck finish is an important part of bottle and closure sourcing. This aluminum screw cap is available in four neck specifications: 18/410 aluminum cap, 20/410 aluminum cap, 24/410 aluminum cap and 28/410 aluminum cap.

The availability of multiple neck sizes makes it easier for brands to develop a coordinated packaging range using similar closure styles across different bottles. For example, smaller neck sizes may be selected for compact bottle formats, while larger neck finishes can be considered for larger packaging configurations, depending on the bottle design and product requirements.

If you are unsure which neck finish is required, provide your bottle specifications or bottle samples to UNALILIA PACKAGING. Our team can assist with bottle and closure matching for your packaging project.

Gold, Silver and Black Aluminum Caps

Color plays an important role in packaging design. This aluminum screw cap is available in three versatile colors: gold, silver and black. Each option provides a different visual direction for product packaging.

• Gold Aluminum Cap: Suitable for packaging designs that require a decorative or premium-looking metallic accent.
• Silver Aluminum Cap: Offers a clean metallic appearance that can coordinate with a wide variety of bottle and label designs.
• Black Aluminum Cap: Provides a modern and minimalist appearance suitable for many contemporary packaging concepts.

These colors can be paired with clear, frosted, white, black, amber or other compatible bottle designs. Packaging buyers can select a color according to their brand identity, product positioning and overall packaging concept.

Aluminum Material for a Distinctive Packaging Appearance

Compared with a standard plastic closure, an aluminum bottle cap provides a recognizable metallic appearance. This makes aluminum closures particularly useful for brands that want to introduce metal elements into their packaging design.

The simple screw cap format also makes the closure suitable for a wide range of bottle styles. Depending on the project, aluminum caps can be incorporated into minimalist, modern, professional or premium packaging concepts.

Because packaging requirements vary between products, the final cap selection should take into account the bottle neck specification, bottle material, product formulation, filling process and intended application. Testing with the actual bottle and formulation is recommended before bulk production.

Applications for Aluminum Screw Caps

Our aluminum bottle caps can be considered for a variety of packaging applications. Typical projects may include:

• Cosmetic packaging
• Beauty product packaging
• Skin care packaging
• Personal care packaging
• Hair care packaging
• Fragrance and aroma packaging
• Body care packaging
• Other compatible bottle packaging applications

The appropriate application depends on the complete packaging configuration and product formulation. For commercial projects, we recommend confirming the compatibility of the cap, bottle and final formulation before mass production.

Matching Aluminum Caps with Your Bottles

A cap should not be selected based on diameter or appearance alone. The bottle neck and closure specifications need to match correctly. Our aluminum screw caps are offered in 18/410, 20/410, 24/410 and 28/410 options to accommodate different compatible bottle neck finishes.

UNALILIA PACKAGING also supplies bottles and other packaging components, making it possible for customers to source both bottles and closures for a complete packaging project. If you already have a bottle design, send us the neck specification and project requirements. If you need both the bottle and cap, our team can recommend suitable combinations from our packaging range.
