The D.S.E Soret WT Series is a series of foot-type impulse sealer with double sealing mechanism that functions through being controlled by foot, thus allowing the hands to freely feed the machine. Furthermore, this machine generally produces heat from upper and lower jaws to guarantee a quality sealing given any type of materials -- even the thickest ones.
In addition, this machine has a sealing width of 5mm / 10mm as well as a sealing length of 300 - 750 mm depending upon the model.
