Folded Aluminium Lids durable design with a refined metallic edge

Folded Aluminium Closures

Introduction
Folded aluminium closures provide a clean and minimalist alternative to traditional rolled-edge designs. They deliver the same level of strength and functionality, with a more understated and modern aesthetic. Frapak and FlexPET leverage over a decade of experience to produce high-quality folded aluminium closures that cater to the demands of contemporary packaging.

Design and Manufacturing Process

Folded aluminium closures feature a straight-edge design, achieved through the following steps:

1. Punching: Aluminium plates are punched to precise specifications to form the closure’s base.
2. Folding: The edges are carefully folded, resulting in a straight, clean finish that stands out for its simplicity.
3. Thread Rolling and Knurling: Threads are rolled into the closure for secure attachment to containers. Knurling can be included for added grip or omitted for a smooth, refined design.

As with rolled closures, folded aluminium closures are finished with a food-safe lacquer to meet regulatory standards for safe use with consumable products.

Key Features and Benefits

• Modern Aesthetic: The straight-edge design offers a contemporary appearance that aligns with current packaging trends.
• Structural Integrity: Despite their minimalistic look, folded edges provide the same level of rigidity as rolled closures, ensuring reliable performance.
• Customisation Options:
• A wide range of colours is available, including dual-colour designs that make the closures stand out.
• Embossing and debossing allow for unique branding elements, such as logos or decorative details.
• Full-colour printing on the aluminium plates enables intricate designs tailored to specific branding requirements.

Applications

Folded aluminium closures are particularly well-suited to packaging in the cosmetics, luxury goods, and high-end food and beverage industries. Their streamlined design and customisation options make them a preferred choice for brands that value both function and style in their packaging solutions.
