The Pure-Twist range of closures is developed for long-life products and aseptic filling. They are applied by a mandrel applicator before filling or by a post applicator after filling.
Pure-Twist closures include a tamper evident band to indicate when the pack has been opened or tampered with. They are fully reclosable. The closures are applied to the carton by hot air or ultrasonic welding. A half cut maintains the barrier properties of the carton until it is opened. The cutter of the closure pierces the last layer of the carton, and the half cut opens. This breaks the board seal.
