Overcappers are specialized packaging machines designed to securely apply external caps onto containers that already have an initial seal, such as plugs or pumps. These machines are versatile and can handle a variety of container shapes and cap types, making them suitable for a wide range of products including cosmetics, household cleaners, and personal care items like hairspray. The process ensures that the final product is tamper-evident, maintains product integrity, and extends shelf life by adding an additional layer of protection against external contaminants. Overcappers are essential in industries where product safety and consumer convenience are paramount.

Typical products and applications include:

• Hairsprays and body mists: Capped with protective overcaps to cover pump or aerosol actuators
• Household cleaning sprays: Overcapped to prevent accidental dispensing during shipping
• Cosmetic bottles (e.g., foundations, serums): Finished with decorative or protective caps for shelf appeal
• Food oils and condiments: Overcapped after inner seals or spouts to maintain cleanliness and freshness
• Pharmaceutical or OTC products: Secondary caps applied to ensure tamper evidence and regulatory compliance

Additional Considerations:

• Enhances tamper resistance and product presentation: Provides an extra layer of security and a polished appearance
• Compatible with various cap and container styles: Works with snap-on, press-on, or threaded overcaps
• Available in semi-automatic or fully automatic formats: Suitable for both small-scale operations and high-speed lines
• Improves shipping and shelf stability: Overcaps help protect dispensing components from damage or leakage
• Integrates with upstream filling and sealing systems: Easily added to complete packaging lines for streamlined operations
