Fully-automatic Bag in Box Line for Packaging Semi-Liquids Like Margarine Shortening

The finished product is a spoutless bag in box, different from a standard bag-in-box which is with a spout and fitment. The line cuts and seals film as a bag from a roll stock, inserts it in an erected carton, opens and cuffs the bag over the carton top flaps, blows air to extend the bag to fit the internal wall of box better.

This bag in box line is designed for packaging semi-liquids like margarine, butter, cream and even wax in bulk with spoutless bags in boxes. This bag in box filling and packaging line includes a carton erector, a poly bag inserter (carton lining machine), a filling machine, a liner bag sealer, a carton sealer and conveyors. The cartons can be sealed with tape or hot melt glue.

This poly bag inserter feeds film from a roll stock, cuts and seals to form a bag, inserts the bag in an erected carton, opens and cuffs the bag over the carton top flaps, blows air to extend the bag to fit the internal wall of carton better. The bag inserting machine reduces labor and material costs, is simple to operate and easy to adjust. High efficiency and labor saving.

The bag sealer uncuffs the bag off the carton top flaps, then folds it inwards from sides, vacuumizes the bag (optional), heat-seals the bag top and then flattens it in the carton.
