We offer you for every common bag material (PE, LDPE, EVOH, aluminium- and paper coated) the matching closing technology. Depending on your requirements, we provide executions with impulse sealing or ATEX approved heat-sealing. As an alternative to the thermal systems we provide you also an half-automatic crimp automat.
