Guala Closures, a global leader in specialty beverage closures, has launched its innovative No Glue Systems (NGS) concept. This cutting-edge range of stopper technologies is aimed at eliminating adhesives while enhancing performance, sustainability, and product integrity within the food and drink packaging industry.
Traditionally, T-bar stoppers are secured using chemical adhesives that attach cork shanks to the head. However, environmental factors such as thermal shocks and fluctuating conditions can lead to detachment, jeopardizing product integrity and diminishing the consumer experience.
Guala Closures’ No Glue Systems effectively address this persistent issue through advanced engineering techniques, including co-injection moulding, ultrasonic welding, and mechanical interlock designs. These innovative methods forge a secure and durable bond between the cork and head—eliminating the need for adhesives.
The outcome is a closure that guarantees reliable performance under various climates and production conditions. This not only protects product quality but also preserves brand reputation and boosts consumer satisfaction.
With No Glue Systems, Guala Closures equips spirits producers globally with a solution that fortifies product integrity, adheres to environmental commitments, and elevates the consumer experience.
“Our No Glue Systems represent a significant step forward in closure technology,” stated Piero Cavigliasso, Group Chief Product Development & Innovation Officer at Guala Closures. “By removing adhesives, we not only tackle a technical challenge within the industry but also provide a more sustainable, reliable, and premium industrial-ready solution that enhances the consumer experience”.
Central to No Glue Systems is Sughera, a patented micro-agglomerated cork material developed by Labrenta, a leader in luxury closures acquired by Guala Closures in 2022.
Sughera seamlessly merges the natural aesthetics of cork with the technical advantages of elastomeric polymers. With up to 60% recycled cork content by volume, Sughera significantly minimizes environmental impact compared to traditional virgin polymers, while ensuring premium performance and appearance.
Complying fully with ESG and circular design principles, Sughera offers impressive dimensional stability and oxygen permeability akin to natural cork. This makes it an excellent choice for premium spirits closures, delivering both sustainability and high-end appeal.
No Glue Systems are available now on an industrial scale for immediate production at Guala Closures’ facilities, representing a key advancement in food and drink sustainable packaging.
