How open-mouth bag fillers work

Automated open-mouth baggers are designed to fill and seal pre-made open-mouth bags quickly and efficiently.

Product is weighed via a net or gross weight scale and fed into a bag. The bag moves through a sealing station, after which it can go be further processed or palletized.
