Xtra-Lok mini ‘S’ 28mm closure

US-based Closure Systems International (CSI) has unveiled its new Xtra-Lok mini ‘S’ 28mm closure for short-height carbonated soft drink bottles.

The lightweight closure incorporates the company’s rugged XT liner and bead behind the wing tamper band for package security, and delivers enhanced packaging cost and sustainability, CO2 performance and improved impact resistance, according to the company.

CSI carbonated soft drinks global marketing manager Clint Rush said that the mini S design delivers total material savings of over 10% when compared to the first generation of 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. Bottlers can quickly adopt the new lightweight closure with minimal adjustments," Rush added.

The material savings on a typical truckload order are expected to be over 4,000lbs of plastic, which can reduce the carbon footprint and the use of plastic in the packaging.

According to the company, the Xtra-Lok mini S has been designed to work for packages in sizes ranging from 250ml up to 3l in volume.

The closure is also said to provide consumer advantages such as ease of opening, secure tamper-evidence and better impact performance.

CSI, which is a part of Reynolds Packaging Division, an operating division of The Rank Group, serves major sectors including carbonated soft drinks, bottled water, juices, isotonics, teas, adult beverages, dairy, foods and automotive fluids.
