The BEL 451 is a semi-automatic poly bag inserter / case former & pack station with bottom only case taping. It is designed for manual bulk filling lines where a poly bag liner is required to be inserted into the case before filling. The operator positions the case on the vacuum plenum with the minor flaps folded, places the liner in the case and cuffs it over the open top flaps.

The vacuum then draws the bag fully into the case leaving no voids in the box corners. The case is then moved forward into the conveyor where tape is automatically applied to seal the bottom flaps closed. The lined case is then ready to be filled.

The BEL 451 semi-automatic poly bag inserter / case former is a cost effective, clean approach to providing bulk filling lines with a ready, on demand supply of lined cases while improving operating efficiencies and ergonomic safety.
