Offering a 12 inch sealing size, the 300 Standard impulse heat sealer closes plastic bags and pouches made of PE, PP and laminated films. It has an orange base with a black sealing strip, a cream hinged arm with a black knob handle, a knob at one end and a power cord with a three-pin plug. Operation is manual: the arm is pressed down over the bag mouth to heat-seal the pouch closed.
