CSI unveils new lightweight 28mm closure

Closure supplier in the US, Closure Systems International (CSI) has unveiled its new Xtra-Lok mini ‘S’ 28mm closure for the short-height carbonated soft drink bottle. The closure features a lightweight design that delivers enhanced packaging cost and sustainability, good CO2 performance and improved impact resistance.

CSI Carbonated Soft Drinks global marketing manager Clint Rush said the total material savings in the improved mini S design is over 10%, when compared to the first generation short-height closure design.

"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," Rush added.

"Bottlers can quickly adopt the new lightweight closure with minimal adjustments," Rush concluded.

The Xtra-Lok mini S has been engineered to work for packages ranging in size from 250ml up to 3l in volume and provides advantages including consumer-preferred ease of opening, secure tamper evidence, and good impact performance. It includes CSI’s rugged XT liner as well as bead behind the wing tamper band for maximum package security.
