It is an ideal bulk box packaging line for shortening, margarine, butter or other semi-liquid. 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 erects cartons and seals bottoms, inserts and lines bags in cartons by one each from a roll stock film to form bag-in-box packaging (lined cartons), weigh fills with hot-melt margarine/butter/shortening, vacuumizes and heat-seals the bag tops, seals the box top.

The bag in box line includes a carton erector, a poly bag inserter (box lining machine), a weigh filling machine, a 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.
