Abstract
An energy discharge circuit includes a high-power ultracapacitor 4 for providing pulses of electrical energy to a sealer 8 in an apparatus for sealing a plastic bag 38. The ultracapacitor 4 is charged by a power supply 30 and discharges the stored energy to the sealer 8, thereby enabling the sealing apparatus to seal the plastic bag 38 without the need for a high energy continuous electrical power source.
