two head film blowing machine with one extruder,one gear box,with two die head or two mould,can produce two roll film at same time.
The process of Two Die Head Blown Film Extrusion utilizes a single screw and barrel with dual molds. The extruder’s cylinder and screw are made from high-quality alloy steel through nitration and precision finishing methods to ensure superior hardness and resistance to corrosion. This machine setup, which comprises two heads on a single extruder, is designed to boost production capacity, lower energy consumption, minimize labor expenses, and reduce required workspace. It is primarily employed for producing Low-density polyethylene (LDPE) and high-density polyethylene (HDPE) plastic films, used in creating a variety of vest bags and flat-rim bags commonly found in the food, garment, and textile packaging sectors, among others.
