Hi,I need a stand up pouch bag machine with gusset and zipper (doy pack) for roll film production. I don't need the filler unit as the empty bags are transported to another production site (no need for stainless). The required three sizes are 160*270, 200*280 and 250*340/240*350 that need to be made on the same machine. Speed is 40 to 60 /min. please send me a quote for the equipment to thank you.
