SIG Combibloc combiCap lightweight screw cap

With the screw cap combiCap, SIG Combibloc has expanded its product range by adding a screw cap that weighs just 1.85 g. The closure can be applied to carton packs using existing closure applicators with a minor adjustment.

Based on a process developed by SIG Combibloc, holes of the correct size are punched in the raw carton board before it is laminated. Once the product has been filled into the carton pack, the screw cap is applied to the over-coated hole. The closure can then be easily opened by the consumer with a single twist, as the cardboard layer has already been removed and only the thin aluminium and polyethylene layers need to be pierced.

The closure consists of a flange with integrated cutting ring and a screw cap. The tamper evidence feature on the original seal is broken with an audible click. To reclose, the cap is screwed back on, ensuring the carton pack remains leak proof.
