The Airstream bag debuts for fine, powdered bulk material as a reported solution for quick de-aeration without perforating the PE barrier/foil. The co. says that air freed in the valved bag during filling forms a stream that's directed to a high-capacity outlet, an interrupted longitudinal seam, and escapes to accelerate the filling process. The co. adds that the Airstream also supports reduction of dimensions toward an optimized size and cleaner bags.
