Tekni-Plex, Inc. has engineered a new laminated aluminium foil-foam barrier liner, available globally, to deliver performance, cost and environmental attributes for roll-on pilfer-proof (ROPP) wine closures.
Tri-Vin liners from Tekni-Plex’s Tri-Seal division deliver performance attributes that support wine aging and drinkability, the firm said. The aluminium foil-foam lamination has been engineered to replace tin and Saran barrier liners commonly used for ROPP wine applications.
Permeation tests have been conducted by an independent laboratory comparing alternate materials currently in use. In addition, sensory organoleptic testing has been carried out by the Australian Wine Research Institute, Tekni-Plex added.
Tekni-Plex vice president and general manager David Andrulonis said: “We invested significant resources to develop a cost-effective wine liner with the performance characteristics of tin/Saran liners, while preserving aroma and taste. We designed the Tri-Vin liner to perform in the correct oxygen sensitivity range, allowing wine makers to cost-effectively maintain the drinkability window for consumers. Additionally, the structure is halogen and chlorine free, which is environmentally desirable.”
