POLYSTAR has installed over 300 sets of its twin-head blown film machines globally, notably in leading T-shirt bag makers' factories. The twin-head design offers an economical solution, delivering higher output and faster return on investment compared to machines with internal bubble cooling systems. This design accommodates a larger extruder (e.g., 65mm or 75mm) for smaller film widths (300-700mm), proving effective for T-shirt bag makers seeking higher output at a lower cost. With dual die heads dispersing high extrusion output, it achieves greater production capacity for narrow film rolls. Polystar customizes these machines with varying screw diameters (55mm-75mm) and film widths (400mm-1000mm) on each winder, allowing seamless switching between HDPE and LDPE production. Special screw design ensures stable output for both materials, with bimetallic treatment enabling processing of recycled material. Siemens/ABB energy-saving motors reduce energy consumption up to 5%. Over 200 sets of these machines are operational in 15+ Latin American
