A material spill avoiding dispenser system , comprising: a dispenser which dispenses dispenser material; an end film sealer and cutter means comprising at least one crosscut/cross-seal resistance wire mechanism for forming a seal in the film and, optionally, for forming a cut in the film, at a formation location; and a material spill prevention system characterized in that the material spill prevention system includes: a bag feedthrough monitoring system configured to monitor a feedthrough of bags in the dispenser system , said bags being configured to receive dispenser material from said dispenser, wherein said bag feedthrough monitoring system includes: a control unit in communication with at least one material spill prevention sub-system; and a sensor system in communication with said control unit, said sensor system positioned downstream of end film sealer and cutter means , said sensor being configured to detect whether a cut and/or sealed edge section of a bag being fed through the dispensing system timely travels from a first point at the formation location to a second point downstream of the formation location, said sensor system being in communication with said control unit such that if sensor detection of the bag edge seal or cut does not occur within a time period, said control unit communicates with the at least one material spill prevention sub-system to initiate a dispenser shutdown sequence. a dispenser which dispenses dispenser material; an end film sealer and cutter means comprising at least one crosscut/cross-seal resistance wire mechanism for forming a seal in the film and, optionally, for forming a cut in the film, at a formation location; and a material spill prevention system characterized in that the material spill prevention system includes: a bag feedthrough monitoring system configured to monitor a feedthrough of bags in the dispenser system , said bags being configured to receive dispenser material from said dispenser, wherein said bag feedthrough monitoring system includes: a control unit in communication with at least one material spill prevention sub-system; and a sensor system in communication with said control unit, said sensor system positioned downstream of end film sealer and cutter means , said sensor being configured to detect whether a cut and/or sealed edge section of a bag being fed through the dispensing system timely travels from a first point at the formation location to a second point downstream of the formation location, said sensor system being in communication with said control unit such that if sensor detection of the bag edge seal or cut does not occur within a time period, said control unit communicates with the at least one material spill prevention sub-system to initiate a dispenser shutdown sequence. a control unit in communication with at least one material spill prevention sub-system; and a sensor system in communication with said control unit, said sensor system positioned downstream of end film sealer and cutter means , said sensor being configured to detect whether a cut and/or sealed edge section of a bag being fed through the dispensing system timely travels from a first point at the formation location to a second point downstream of the formation location, said sensor system being in communication with said control unit such that if sensor detection of the bag edge seal or cut does not occur within a time period, said control unit communicates with the at least one material spill prevention sub-system to initiate a dispenser shutdown sequence. <EOS>
