Guala Closures presents the evolved version of Alusnap with tamper-evident features

Guala Closures has presented the latest evolution of Alusnap, one of the company’s leading premium closure ranges.

For many years, Alusnap has been successfully adopted by premium spirits brands worldwide, thanks to the combination of aluminium’s aesthetic elegance and reliable mechanical protection. Today, as counterfeiting techniques continue to develop and become more sophisticated, anti-counterfeiting systems are evolving accordingly.

Anti-counterfeiting technologies

The enhanced version of Alusnap brings greater opportunities for premium differentiation through advanced embossing and debossing technologies, together with new tamper-evident solutions designed to further strengthen consumer confidence and brand protection.

Current industry estimates indicate that between 25% and 40% of the spirits consumed globally could be counterfeit or produced through illicit practices. This widespread phenomenon damages brand value, compromises consumer safety and undermines trust in premium products.

“Being a leader in security solutions for premium spirits does not simply mean having been the first to invent a particular technology: it means constantly monitoring the evolution of counterfeiting, understanding how sophisticated the threats are becoming and evolving our solutions accordingly. That is exactly what we are doing with ALUSNAP: we start from what works, adapting and continuously refining it to address new challenges”, commented Andrea Lodetti, CEO of Guala Closures.

The new features

Today, Alusnap combines its tried-and-tested structure with an expanded portfolio of premium features dedicated to design and security:

• Established anti-refill technology: thanks to Guala Closures’ original double-glass-ball anti-refill valve system, which offers reliable, long-lasting protection against illicit refilling.
• Anti-extraction system: an integrated hook design firmly locks the pourer onto the bottle neck, resisting forced extraction and helping to preserve product integrity.
• Enhanced tamper evidence: the range can now integrate Indicator, an additional, highly visible tamper-evident element that immediately alerts consumers if the closure has previously been opened.
• Controlled premium pouring: the pourer, designed to ensure smooth and consistent performance, improves pouring quality while reducing dripping and product waste.
• Advanced premium aesthetics: the aluminium shell now offers greater customisation possibilities through sophisticated raised and recessed processing (embossing and debossing) and new surface textures. These premium finishes not only enhance the product’s shelf appeal, but also increase the technical complexity that counterfeiters must overcome to reproduce the closure.

Produced through Guala Closures’ global network of plants – including facilities in Italy, Ukraine, India and Bulgaria – Alusnap offers premium brands a secure, durable closure solution available worldwide.
