Our direct heat sealers (also known as constant heat sealers) are best suited to seal thicker material such as coated aluminum foil, Kraft paper, cellophane, mylar, or coated PP.  Please note that with the exception of our KF-150PS and band sealers, our direct heat sealers cannot seal polyethylene.  Depending on the model of the sealer, material up to 16" wide and 20 mil thick can be sealed.  We offer two types of seal designs:  meshed or serrated.  Seal widths vary from 10mm to 15mm wide.  Our direct heat sealers are equipped with a thermostat or an electronic temperature controller to accurately controls the temperature. Both jaws are heated simultaneously resulting in better heat penetration to seal thicker materials. 

Easy to operate.  Set the temperature on the temperature controller depending on the material to be sealed.  Once correct settings have been reached, press down on the foot pedal and release.
