High-Transparency Greenhouse Film Blowing Machine (3–5 Layers PO Film)
Agricultural Film Production
Co-extrusion blown film extrusion line with integrated coating and drying systems for producing PO films with ≥92% transparency and long-term anti-fogging
Raw material handling unit
Includes a material mixer for precise formula proportioning, automatic feeding system, and a material dryer for high-moisture raw materials.
Extrusion unit
Equipped with 3–5 single-screw extruders (screw diameter 45–65 mm, suitable for PO materials) and a multi-layer co-extrusion die head with flow channels designed for greenhouse films
Forming unit
Blown film air ring with ±1°C temperature control precision to ensure uniform film thickness, together with a stable cooling and shaping system
Anti-fog functional unit
Corona treater (surface tension ≥40 dyn/cm to improve coating adhesion), anti-fog coating tank with circulation and precise spray coating control, and a constant-temperature drying oven (60–85°C) to ensure even and reliable coating film formation
Rewinding unit
Automatic rewinder with tension control to prevent deformation, supporting rewinding speeds of 3–18 m/min with frequency control to match extrusion speed
Control system
PLC control cabinet and touchscreen operation panel capable of storing 10 greenhouse film production recipes, plus a fault alarm and protection system
