PolyOne decided on Pack Expo 2015 as the perfect platform to premiere its low-migration aluminium cap liner technology based on its new GLS Versaflex PKG 4190 TPE.

This advanced solution helps preserve the taste and aroma of sensitive beverages by allowing lower processing temperatures than those used with traditional TPEs. This new material also delivers high seal integrity for extended shelf life and excellent pressure retention of carbonated beverages. Applications include cap liners for roll-on (RO) and roll-on pilfer proof (ROPP) aluminium closures.
Charles Page, Global Marketing Director at PolyOne GLS Thermoplastic Elastomers, said: "As beverage makers develop distinctive new beverages to compete in a dynamic and changing market, they also need sophisticated packaging solutions to maintain product quality, increase brand equity, and enhance customer satisfaction.
"We specifically engineered our Versaflex PKG 4190 low-migration TPEs to preserve the quality of even the most delicate beverages, provide good seal integrity, and allow easy removal of the cap."
As an extension of GLS compression-moulded cap liner technology, this non-PVC Versaflex PKG is formulated for aluminium caps used for sealing glass, polyethylene terephthalate (PET), or aluminium containers. The materials deliver excellent seal integrity even when processed under ambient or high-temperature pasteurised and hot-fill conditions. In addition to minimising volatiles that can affect the taste of sensitive aqueous, acidic and low-alcohol beverages, its lower processing temperature also helps save energy and expand manufacturing flexibility.
The new Versaflex PKG material comes as a granular material that is compliant with EU 10/2011 and FDA 177.1210 food contact regulations. It is available globally in white or translucent grades. The translucent grade allows for promotional laser coding on the cap liner.
