Zusammenfassung:	Exemplary embodiments of the present disclosure can provide a foam-in-bag device. The device can include a dispenser unit configured for dispensing a fluid foam-precursor into a web of film material for making foam-in-bag packaging material, a fluid supply conduit connected to the dispenser unit for delivering the foam-precursor to the dispenser unit, a valve connected to the dispenser outlet and that is actuatable between: an open condition allowing flow of the foam-precursor so as to permit the dispensing of the foam precursor, and a closed condition preventing flow of the-foam precursor so as to prevent the dispensing of the foam precursor. The device can further include a power-loss protection mechanism configured to direct auxiliary power to actuate the valve to the closed condition upon a loss of incoming power.
