Blown Film Cylinder Filters are specialized filtration devices designed specifically for the blown film extrusion process. These precision-engineered cylindrical screen assemblies fit within the die head of blown film extrusion lines, providing critical filtration that ensures exceptional film quality, consistency, and clarity. At SUNON Wire Cloth, we manufacture high-performance blown film cylinders custom-designed to match your exact equipment specifications and process requirements.
Unlike flat extruder screens, blown film cylinders feature a cylindrical construction that creates a radial flow pattern, distributing polymer melt evenly around the circumference of the die. This design enables consistent filtration across the entire melt stream, preventing variations in film thickness, optical properties, and mechanical strength.
