Guala Closures Unveils MAGNEX Cap for Spirits Security

Guala Closures, a leading provider of speciality beverage and pharmaceutical closure solutions, has developed MAGNEX, a closure for premium spirits made from electromagnetic forming (EMF) technology.

The process applies high-velocity magnetic pulses to form aluminium directly around a mould, producing complex geometries, micro-engravings and three-dimensional textures that cannot be reproduced through conventional aluminium forming technologies.

‘Most anti-counterfeiting measures fight on the same technological ground as the counterfeiters. EMF changes that equation. The geometries and textures we achieve with MAGNEX are physically impossible to reproduce through standard embossing or metallisation, which means the design itself becomes part of the protection mechanism,’ commented Andrea Tassisto, Group Industrial & Technical Director at Guala Closures.

The closure combines an EMF-formed aluminium outer shell – a sustainable and recyclable material – with an inner component that can also be produced using recycled plastics, reducing the use of virgin resources.

Beyond its distinctive appearance, MAGNEX is designed to address one of the most persistent forms of fraud affecting premium spirits: bottle refilling. Empty bottles of high-value whiskies, cognacs and other premium brands are frequently collected and refilled with lower value products before being resold as genuine.
