- Aluminum cap liners with low-migration TPE
- High seal integrity under high-temperature pasteurized and hot-fill conditions
- Application: cap liners for roll-on (RO) & roll-on pilfer proof (ROPP) aluminum closures
At Pack Expo 2015, PolyOne unveiled a low-migration aluminum cap liner technology based on its new GLS Versaflex PKG 4190 thermoplastic elastomer (TPE). This solution helps preserve the taste and aroma of sensitive beverages by allowing lower processing temperatures than those used with traditional TPEs.
Applications include cap liners for roll-on (RO) and roll-on pilfer proof (ROPP) aluminum closures
This new material also delivers high seal integrity for extended shelf life and very good pressure retention of carbonated beverages. Applications include cap liners for roll-on (RO) and roll-on pilfer proof (ROPP) aluminum closures.
High seal integrity under high-temperature pasteurized and hot-fill conditions
As an extension of GLS compression-molded cap liner technology, this non-PVC Versaflex PKG is formulated for aluminum caps used for sealing glass, polyethylene terephthalate (PET), or aluminum containers. The materials deliver very good seal integrity even when processed under ambient or high-temperature pasteurized and hot-fill conditions. In addition to minimizing 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. The translucent grade allows for promotional laser coding on the cap liner.
