Device flls and seals thermoplastic bags which are open at one end and are pref. the type with side folds, it has a pair of grips at the sides of the open end and these can open and close. It has also a pair of suction members to draw open the sides of the bags, it lowers and raises a filling tube into/from the opened bags, and it welds together the taut sides of the open bags to seal them. A conveyor holds the flat bags which are sealed at the bottom and moves them to beneath the filling tube; a pivoting mechanism holds the grips at the top and takes over the bags to a position where they are aligned with the filling tubes. When the bags are filled the pivoting mechanism applies the welding jaws to seal them and then bring and hold the next bag for similar treatment.
