New aseptic beverage carton screw cap debuts in Europe

The first commercial user of a new three-piece screw cap mechanism for aseptic beverage cartons has been introduced in Germany by Milchwerke Thüringen GmbH, a subsidiary of the Humana Milchunion group.

The company is using the closures for its Osterland-brand long-life full-cream milk, long-life low-fat milk, and long-life skimmed milk.

SIG Combibloc’s “combiSwift,” closure consists of a flange with an integrated cutting ring and cap. A pouring/drinking hole is prepunched into the raw carton material before it’s overcoated with aluminum and polyethylene. After the carton is filled, the closure is applied to the overcoated hole. As a result, consumers can open the cap with a single twist as the cutting ring easily and precisely severs the thin aluminum and PE layers to expose the clean, prepunched pouring/drinking hole.
