CSI Unveils New Lightweight Closure for Soft Drink Bottles

Critical closure performance criteria on which Xtra-Lok mini S excels include superior CO2 retention, consumer-preferred ease of opening, secure tamper evidence, and robust impact performance.

15 Jun 2012 --- Closure Systems International’s new Xtra-Lok mini ‘S’ 28mm closure for the short-height carbonated soft drink bottle finish features a best-in-class lightweight design that delivers improved packaging cost and sustainability, superior CO2 performance, and enhanced impact resistance. “Compared to the first generation short-height closure design, the total material savings in the improved mini S design is over 10 percent,” explained Clint Rush, CSI Global Marketing Manager for Carbonated Soft Drinks. “Virtually all areas of the closure were very carefully evaluated, and select areas were re-engineered to yield substantial material reductions - with no sacrifice in performance. On a typical truckload order, the material savings will amount to over 4000 pounds of plastic. This translates to a reduced carbon footprint and significantly less plastic in the packaging. On the volume scale that bottling customers use annually, this second generation closure delivers impressive environmental and economic sustainability improvements,” said Rush.

Critical closure performance criteria on which Xtra-Lok mini S excels include superior CO2 retention, consumer-preferred ease of opening, secure tamper evidence, and robust impact performance. “While delivering weight savings, the new mini S closure design meets or exceeds the first generation closure performance in all respects,” Rush stated. The mini S closure includes CSI’s rugged and reliable XT liner, as CO2 retention throughout the supply chain provides important competitive advantage for bottlers and protects brand taste and freshness for consumers. “The closure offers several knurl pattern options to deliver improved consumer ergonomics, by being easier to open and close, along with providing the highest safety,” highlights Rush. The mini S cap also incorporates CSI’s patented bead behind the wing tamper band for maximum package security.
