Closure Systems International

Closure Systems International is a global leader in custom plastic and metal closure solutions, notably including aluminum caps for beverage, food & beverage, and personal care products. With decades of experience and recognized innovation in product design and manufacturing, they offer not only caps but also end-to-end technical support and customization for complex packaging challenges.

• Country and City: United States — headquartered in Wood Dale, Illinois (approximate)
• Established Date: 1952 (originally as a small independent closure producer, later expanded globally)
• Key Products: Aluminum screw caps, press-on closures, child-resistant caps, personalized branded closures
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Closure Systems International stands out for its decades of legacy in merging innovation with quality control. Their aluminum cap offerings address both standard and highly customized needs: from tamper-evident designs to brand-rich embossing or printing. For procurement teams, they offer a compelling value proposition—rapid prototyping, material traceability, extensive certification capabilities, and the reassurance of working with a large-scale, U.S.-based supplier.

Given current trends emphasizing supply-chain resilience and domestic sourcing, partnering with CSi can reduce import risks and lead times while maintaining high design flexibility. That said, if your project demands nested integration (design, production, secondary packaging, global shipping coordination), comparing them with a vertically integrated alternative like Packsar may inform your decision-making further.

Crown Holdings, Inc.

Crown Holdings, Inc. is a global leader in metal packaging and closures, known for high-volume production of aluminum and steel components for beverages, food, and specialty markets. Crown combines deep tooling expertise with large-scale stamping and finishing capabilities, making it a frequent choice for brands that require durable, tamper-evident, or highly-branded metal closures.

• Country and City: United States — multiple U.S. manufacturing sites (headquartered in the U.S. with global operations).
• Established Date: Founded in the late 19th century (legacy company with over a century of operations).
• Key Products: Aluminum screw caps, crown corks, specialty metal caps, can ends, aerosol can components.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Crown’s scale and long history make it an excellent option for buyers who need high annual volumes, strong quality systems, and deep R\&D for printing/branding on metal. For procurement teams, Crown offers predictable capacity and global support — useful for brands that require both domestic production and international footprint. However, very small or highly-custom niche projects may face minimums and longer lead times compared with specialized or more flexible suppliers.

Silgan Packaging

Silgan Packaging is a major North American manufacturer of metal and plastic packaging components, including metal closures for food, beverage, and specialty products. The company emphasizes integrated services — tooling, finishing, and supply-chain support — and serves both private label and large brand customers.

• Country and City: United States — multiple U.S. plants and regional service centers.
• Established Date: Corporate group formed in the late 20th century (extensive acquisition history).
• Key Products: Aluminum screw caps, metal closures for food jars, lined lids, tamper-evident solutions.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Silgan is attractive for food and beverage importers who prioritize regulatory compliance (food contact liners, traceability) and multi-site supply reliability. Silgan’s broad manufacturing footprint can reduce transit times within North America; however, buyers should confirm MOQ, lead times for custom embossing/printing, and whether small-batch tooling is feasible for pilot runs.

Bericap (U.S. operations)

Bericap is an international specialist in closures with a strong technical focus on precision closures and sealing systems. Through its U.S. operations and regional plants, Bericap supplies metal and composite closures for beverage, food, chemical, and pharmaceutical markets.

• Country and City: United States — U.S. production and service sites (regional presence).
• Established Date: Global company with decades of closure-industry experience.
• Key Products: Precision screw caps, tamper-evident seals, liner systems, and engineered closures.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Procurement teams often choose Bericap when product performance (seal integrity, regulatory compliance) is mission-critical — for example, products requiring reliable shelf life or chemical compatibility. Bericap’s engineering focus helps when you need technical support (material selection, liner specification), but custom tooling or very small order pilots should be discussed up front to confirm economics.

Guala Closures (U.S. presence)

Guala Closures is a global supplier of caps and closures, with capabilities that include aluminum caps, screw closures, and specialty finishes. They serve wine & spirits, food, cosmetics, and industrial customers and provide high-quality finishing (printing, varnish, embossing).

• Country and City: United States — operates regionally with distribution and manufacturing partnerships.
• Established Date: Global company with long-standing history in closures.
• Key Products: Aluminum capsule closures (wine & spirits), specialty decorative caps, tamper bands.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Guala is particularly well-suited for brands in wine & spirits and premium consumer goods that need attractive, branded aluminum capsules and decorative finishes. If your project is design-forward (high-end visuals, customized embossing), Guala’s finishing capabilities can add brand value. Confirm minimum orders and lead time for bespoke finishes.

Ardagh Group (North America)

Ardagh Group is a major metal and glass packaging producer with North American operations focused on rigid packaging solutions. Ardagh’s strength lies in combining metal forming, coating, and finishing capabilities for durable, branded closures and components.

• Country and City: United States — North American production footprint.
• Established Date: Legacy operations consolidated under broader Ardagh Group (long industrial heritage).
• Key Products: Metal closures, aluminum ends, specialty metal components for beverage and food sectors.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Ardagh is a go-to when supply continuity and integrated metal finishing are priorities. Their metal-forming capacity supports high-run closures and can be attractive for customers looking to scale. As with similar large suppliers, be explicit about sample expectations, lead times for custom artwork, and whether secondary packaging or kitting is provided.

AptarGroup, Inc.

AptarGroup is known for dispensing systems and specialty closures; while better known for plastic dispensers, Aptar also offers metal closures and hybrid solutions for personal care, pharmaceuticals, and specialty food & beverage applications.

• Country and City: United States — multiple U.S. sites and innovation centers.
• Established Date: Long-established engineering company with global reach.
• Key Products: Dispensing closures, specialized metal hybrid closures, precision sealing systems.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Choose Aptar when dispensing performance, dosing accuracy, or child-resistant/medical compatibility matters. Aptar’s engineering and regulatory know-how benefits customers in regulated categories. For simple commodity aluminum caps, it may be more than required; for engineered closures, it’s a strong match.

Ball Corporation (Metal Packaging)

Ball Corporation is a leading manufacturer of metal packaging, primarily known for aluminum beverage cans and metal ends. Ball’s scale in metal forming, coating technology, and global supply chains makes it a major player where high-volume aluminum components are required.

• Country and City: United States — North American manufacturing footprint.
• Established Date: Founded in the 19th century (legacy manufacturing company).
• Key Products: Aluminum cans, can ends, specialty metal packaging components.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: If your product needs high-volume aluminum components (e.g., beverage market), Ball’s manufacturing scale, material expertise, and coatings know-how are compelling. Ball is less focused on small-run, highly-custom decorative screw caps for specialty markets — for that, a niche closure specialist may be a better fit.

Lindal Group (Lindal Valve & Closures)

Lindal Group specializes in valves and closure solutions, particularly for aerosols and pressurized containers. Their technical focus on valve engineering and metal components complements aluminum cap designs where valve integration or precision sealing is required.

• Country and City: United States — regional operations and production partnerships.
• Established Date: Long-standing valve and closure specialist.
• Key Products: Aerosol valves, metal closure systems, precision sealing components.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: Lindal is a fit for customers whose aluminum caps must interface with valves or provide controlled dispensing (aerosols, sprays). For general-purpose screw caps, Lindal may be over-specialized; for engineered closure solutions, their technical support and testing capabilities add value.

TricorBraun (Packaging Solutions & Distribution)

TricorBraun is a leading packaging supplier and distributor in North America that also coordinates production and custom sourcing for closures, including metal caps. They act as a procurement partner, pairing buyers with suitable manufacturers (domestic or international) and handling logistics, quality checks, and value-added services.

• Country and City: United States — headquartered in the U.S. with nationwide coverage.
• Established Date: Established packaging specialist with decades of market presence.
• Key Products: Sourced aluminum caps, closure systems, packaging assemblies, procurement services.
• Company Image: (insert your image here)
• Product Image: (insert your image here)

Review: TricorBraun is effective for buyers who prefer a single point of contact to manage supplier selection, quality assurance, and logistics. They simplify procurement but often act as an intermediary — if your priority is purely domestic manufacturing, confirm which U.S.-based plants will handle production and request direct factory visits or audits if needed.

Conclusion

Sourcing aluminum caps in the United States in 2025 means balancing scale, technical capability, lead time, and cost. Large metal packaging firms (Crown, Ball, Ardagh, Silgan) provide scale and strong quality systems — best for high-volume programs. Specialist closure makers (Bericap, Guala, Lindal) offer technical sealing, finishing, and decorative expertise for premium or regulated products. Distributors and solution providers (TricorBraun, certain Aptar divisions) simplify procurement and value-add services but may not always represent a direct factory relationship.
