This fully-automatic poly bag inserter (carton liner placer) is designed for lining cartons with polybags by one each. The machine cuts and seals polyethylene film as a bag from a roll stock, inserts it in a formed box, opens and cuffs the bag over the carton top flaps, blows air to extend the bag to fit the internal wall of box better. The box lining machine reduces labor and material costs, is simple to operate and easy to adjust.

This is an ideal machine for bulk box packaging of bread rolls, edible oil and fat, fruit and vegetable, granules and nuts, meat and fish, caps and closures, golfs and other. It will be more efficient and save more labor if this poly bag inserter works with a carton erector because the combination can be an automatic lined carton forming line.
