Food packaging: New liners for wine
Available globally, the Tri-Seal Tri-Vin laminated aluminum foil/foam barrier liner is engineered for roll-on pilfer-proof (ROPP) wine closures. It supports the aging of wine and promotes drinkability while cutting costs and protecting the environment. (Tri-Seal is a division of Tekni-Plex, Inc.)
Tin/Saran barrier liners are more commonly used for ROPP wine applications, but the new liner is a cheaper, environmentally friendly option that can easily replace them. Permeation tests were conducted by an independent laboratory to compare the performance of the laminated aluminum foil/foam barrier liner with that of alternate materials currently in use. In addition, the Australian Wine Research Institute carried out sensory organoleptic testing on the Tri-Vin liner.
“We invested significant resources to develop a cost-effective wine liner with the performance characteristics of tin/Saran liners, while preserving the wine’s aroma and taste,” explains David Andrulonis, vice president and general manager of Tekni-Plex.
The Tri-Vin liner performs in the oxygen sensitivity range that allows wine makers to cost-effectively maintain the drinkability window for consumers, according to Andrulonis. In addition, since the structure is halogen and chlorine free, the aluminum foil/foam combination is environmentally desirable.
Tri-Seal has been developing extrusion and lamination technologies, as well as sealing applications, for food and beverage packaging for more than 50 years. It manufactures liners in a variety of materials, ranging from nine-layer coextrusions and laminations to a one-piece induction seal.
