• These flexible bags are designed by superposition of at least two films of synthetic material, mono or multilayer depending on the product contained. After filling, they are packaged in containers, usually in the form of cardboard boxes, or even synthetic material. Precisely, the packaging technique usually adopted consists of preforming packaging cartons suitable for the capacity of the flexible bags, then to route them to the filling unit of said pockets.
• this carton while being closed at its lower part, has, in its upper part, flaps of closure kept as far as possible open and away from the trajectory of the further, through the funnel itself.
• the funnel must be defined of small section, to be certain of the insertion of a flexible pocket without addicted in this cardboard, while passing through the preserved opening at the level of the latter.
• the present invention aims to remedy all of the aforementioned drawbacks through a method of packaging of flexible bags and an installation for its implementation whose particularity lies in the fact that a flexible bag is introduced into a carton using not only a funnel, but also through a tube introduction extending the latter so as to extend substantially over the entire height of the carton.

• the introducer can have a section that is substantially smaller than the internal section of the carton, while maintaining, over a large part of its height and, in particular, at the junction with the funnel, a section adjusted to this section inside the carton, so as to offer the flexible bag a free passage as important as possible.
• the installation can be designed in a linear way or in the form of a rotary station whose means which compose it, in particular, the means of taking care of a preformed cardboard, its commitment on the tube for introducing a funnel, its tilt in inclined position, its straightening and its evacuation, are controlled by cams, more particularly fixed or moving cams, concentric with the axis of rotation of the rotary station.
