The sealing jaw system (100) comprising: a first sealing unit (110) and a second, opposite, sealing unit (120), each sealing unit (110, 120) comprising: an upper shaft (111) and a lower shaft (112) driven by associated motors (180a, 180b) and having a pair of drive pulleys (115a) and three pairs of freely rotatable pulleys (115b) coaxially arranged with the shaft (111, 112); two pairs of drive bands (130a, 130b) and two pairs of driven bands (131a, 131b). Each sealing jaw unit has a sealing jaw (105a, 105b) and a coupling member (113a, 113b), and each pair of driven bands (131a, 131b) are driven by a pair of drive bands (130a, 130b) of the opposite one of the first and second sealing units (110, 120) via a coupling action between a coupling member (113a) of the pair of driven bands (131a) and a coupling member (113b) of the pair of drive band.
