Valve cutter VALVOCUT

100% SAFE, 100% DUST-FREE

Patented and in use all over the world: our Valvocut system welds and cuts off vacuum bags safely and with zero dust emission by means of ultrasound. The cutting parameters are automatically adjustable, and even at high capacities, no cooling is required. Thus, both bags and the system itself are immediately usable in further applications.
