Rolled Aluminium Closures

Introduction
Rolled aluminium closures are a premium packaging solution that combines durability with an appealing appearance. With over a decade of experience, Frapak and FlexPET supply high-quality aluminium closures, designed to meet the needs of a wide range of industries. These closures are crafted to provide practical functionality alongside opportunities for detailed customisation.

Design and Manufacturing Process

Rolled aluminium closures are defined by their rounded edge, which is achieved through a precise production process:

1. Punching: Aluminium plates are punched into shape using precision equipment to ensure consistent quality.
2. Rolling and Knurling: The edges are rolled to create a rounded, polished finish that adds structural strength. Knurling is often applied to the top surface to make the closures easier to grip and operate.
3. Thread Rolling: Threads are rolled into the aluminium to provide a secure and reliable fit with the container.

All closures are coated with a food-safe lacquer to guarantee safety for applications involving direct contact with consumables.

Key Features and Benefits

• Strength and Durability: The rolled edge provides additional structural rigidity, ensuring the closures maintain their shape and functionality during use.
• Attractive Finish: The rounded design contributes to the overall aesthetics of the closure, making it suitable for packaging that prioritises presentation.
