Mini Film Blowing Machine New Type


Its extruder, cylinder and screw rods are made of quality alloy steel that have been nitrized and processed in a precision way. Hence it is sound in hardness, durable in corrosion resistance. The specially-designed screw is of sound quality in plasticizing, which helps increase the production capacity. It is applied to blowing the plastic films lik high density polytene (HDPE) and Biodegradable . It is widely applied to producing the packing bags for foodstuff, clothing, rubbish bag and vest ones.
