Closures designed to open. Engineered to perform.
Tethered caps made to fit. Ready for every market.
ALPLA’s tethered closures are now a standardised solution to deliver reliable performance on the shelf, in the hand and across every shipment. From intuitive opening to precision fit, our caps are trusted by global brands for their durability, ease of use and reliable supply. The caps are tailored to meet the packaging demands of today’s largest consumer industries – beverages, food, and milk and dairy. Tethered caps are an EU-regulatory must-have and a packaging essential.
Reliable and efficient by design
Switching to tethered caps would not disrupt your production. ALPLA closures require minimal adjustments, helping you maintain high productivity and long-term cost efficiency.
Our integrated development teams – from R & D and Operations to Sales & Marketing – work with you throughout the project life cycle. With a closure portfolio that covers > 90% of the market volume for ISBT and Cetie needs, we provide robust, tested solutions aligned with ISBT and Cetie standards.
Compliant with EU Single-Use Plastics Directive
