Erect-Line-Fill-Seals. This bag in box forming filling and sealing line is designed for packaging nuts or granules with liner bags in boxes. Erect cartons and seal bottoms to form boxes, insert and line open-top bags in cartons, fill nuts or granules, heat-seal bags and seal box top, all automatically. 

The bag in box packaging line includes a carton erector, a carton lining machine (lining bags in erected cartons by one each), a filling machine, a liner bag sealer, a carton sealer and conveyors. The cartons can be sealed with tape or hot melt glue. 

This carton lining machine inserts a poly bag in a box from a roll stock film, open and cuff the bag over the carton flaps, blow air to expand the bag to fit the internal wall of carton better. The machine reduces labor and material costs, is simple to operate and easy to adjust. High efficiency and labor saving. 

The liner bag sealer uncuffs the bag off the carton flaps, then fold it inwards from sides, vacuumize the bag (optional), heat-seal the bag top and then fold it in the carton.
