The Airstream® family valve bags.

Airsteam and Sheekan are tailored to fine powder filling requirements and high end Air filling machines. A unique de-aeration system significantly improves the air-permeability without affecting the moisture protection function. The air used for filling powdery products is channelled and forms a stream of air which is effectively guided to a high-capacity outlet in the form of a specially designed interrupted longitudinal seam of Airstream bag and a self-closing membrane function located close to the overlap of the back side of the Sheekan Bag.

The air escapes quickly and the filling process is accelerated. As the barrier HDPE film in this construction fully overlaps at least after filling no perforation is needed, it stays completely intact and moisture is effectively kept out. The achieved de-aeration volume also supports a reduction in bag dimensions towards an optimised size for compact shape and cleaner bags.
