Aluminum Screw Cap PP 18, Black — Screw Closure for Miniature Bottles

The Aluminum Screw Cap PP 18, Black is a screw closure for miniature and spirit bottles, featuring a foam polyethylene seal for low-pressure applications and manual capping.

• Aluminum screw closure PP 18
• Foam polyethylene sealing insert
• Designed for spirit bottle closures
• For manual capping, pressure <1 bar
• Packaged 100 pcs per pack for fillers

Secure sealing with a foam insert

The closure uses a foam polyethylene insert that creates a reliable seal even with slight variations in bottle finish. The design maintains tight closure at internal pressures below 1 bar, reducing leak risks during storage and transport.

Compact aluminum design for small bottles

A slim aluminum outer shell offers a sturdy grip and consistent torque during manual capping. The compact form suits miniature bottles and preserves shelf presentation while enabling fast, repeatable application.

Suited for spirit closures and low-pressure use

Made for spirit applications, the screw closure meets the specific demands of spirit filling where internal pressures remain low. Manual closing is supported, allowing simple integration into small-batch production workflows.

Packaging tailored to professional fillers

Delivered in packs of 100 pcs, the packaging supports efficient handling for small and medium production runs. VPE levels are arranged for commercial fillers, and larger quantities are available on pallet for high-volume orders.

Material composition and recyclability

The closure combines a PP 18 threaded interface with an aluminum outer, yielding robust performance and a neat black finish. Recycling classification is noted as 90: C/ALU, reflecting mixed metal-plastic construction.

Kernfeatures

PP 18 threaded interface

The standardized PP 18 thread ensures compatibility with matching bottle necks. Tight fit and predictable engagement reduce rejects during manual capping.

Foam polyethylene sealing insert

The foam insert compensates for minor seat imperfections. This increases sealing reliability without requiring torque-controlled machinery.

Low-pressure rating for spirit applications

Rated for internal pressures below 1 bar, the closure is suitable for spirit bottles and similar low-pressure contents where a secure seal is essential.

Industrial packaging and pallet options

Supplied in practical packs of 100 pcs, the packaging supports logistics for professional fillers. Larger palletized volumes are available for bulk requirements.
