New gas-tight closure to launch at ProWein

In response to market demands, rolled aluminum closure specialist Closurelogic based in Worms, Germany, has developed a new closure that can withstand bottle pressures of up to 5 bar. This capability makes the new 60mm-long Sparkling Star closure suitable for carbonated beverages. Closurelogic will be presenting its new closure solution for the first time next week at ProWein in Düsseldorf, Hall 13, Stand D30, from 15 to 17 March 2015.

Carbonated beverages represent a particular challenge for closures. During transportation, bottle pressure can rise significantly, especially with temperature variations. A closure suitable for CO2-containing drinks therefore needs to be highly resistant to pressure, in order to ensure maximum safety throughout the transportation chain. At the same time, the closure also needs to be easy to handle, tasteless and, ideally, resealable.

Closurelogic’s new Sparkling Star rolled aluminum closure is said to offer all these characteristics. With a diameter of 30mm and a length of 60mm, Sparkling Star provides optimum sealing properties. It has passed the tests and is ready for launch, the company says.

“Short screw caps have long been established for sparkling wines in small bottles”, explains Marion Requena, sales manager for wine and spirit closures at Closurelogic. “Recently, however, we have received an increasing number of requests for BVS 30x60mm closures for carbonated beverages.”

In response to this demand, Sparkling Star is a 30x60 mm closure with a PVC-free seal capable of withstanding pressures of up to 5 bar. Test runs with a major bottling company have confirmed the closure’s pressure-resistant capability and neutral taste. Meanwhile, the first orders have already been received. In addition to the existing 30x60 LongCap Classic for wines, the service bottler Oberhofer in Edesheim, Germany, now offers the capping of the new Sparkling Star closure for CO2-containing beverages. Thanks to appropriate machine optimization, Oberhofer can even offer both types of closure using the same machine settings.

“Sparkling Star is ideal for this constantly growing market”, says Requena. “Because it can be reclosed, the bottled products continue to fizz freshly, even if the bottle was opened the day before.” In addition, the elegant 60mm closure can be decorated with different designs.

In common with all closurelogic aluminium closures, Sparkling Star is also recyclable after use. The metal is then fully available as a raw material again, without loss of quality.

Closurelogic GmbH was spun off from Closure Systems International (CSI) in 2014. The company has been producing rolled aluminium closures in diameters of 28, 30 and 38 millimeters for 45 years. These are suitable for any kind of still, carbonated and alcoholic beverage and for any variety of disposable and reusable container. Each year, Closurelogic produces over three billion aluminum closures and has total annual sales of around 40 million Euros. Just over half of the company’s revenues are generated by sales outside the German market. Around 200 people are employed at Closurelogic’s headquarters in Worms, Germany. The 37,000 square meter facility includes the production and sales departments, a laboratory, research and development facilities and administration. From this site, Closurelogic supplies more than 50 countries worldwide.
