First in a new generation of direct injection moulded closures for gable-top cartons Convenience is key in consumers’ choice between carton packages. They accept nothing less today than packages that are safe, easy to use, and with an inherent attractiveness that brings a smile to both consumers and producers. The latest Tetra Pak offering to meet this demand is the Delta Opening System: a new generation of integrated direct injection moulded openings on Tetra Rex gable-top cartons, for chilled liquid foods. Delta TwistCap, the first member of this new closure generation, made its debut in field tests at the TINE dairy in Bergen, Norway during December 2004. Now Tetra Pak has launched DeltaTwistCap commercially. The Delta Unit, required to apply the DeltaTwistCap, is available as an option on new Tetra Rex TR/7 Series II gable-top filling machines, and as a retrofit to existing TR/7 machines already installed. Machines equipped with the new closure will fill at the standard TR/7 speed of 6000 packages/hour (100/minute).
