Single Screw Film Blowing Machine

CHENQI's MONO HDPE/LDPE Single Screw Film Blowing Machine is suitable for producing plastic films such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), and linear low-density polyethylene (LLDPE). Widely used in the plastic packaging industry, such as garbage bags, shopping bags, and agricultural cover films. The barrel and screw of the extruder are made of high-quality composite steel through nitriding and precision machining, with the best hardness and corrosion resistance. The auxiliary equipment is equipped with a flat workbench, making operation more convenient.

Film Width:
100-1200 mm
Film thickness:
HDPE: 0.009-0.15 mm
LDPE: 0.02-0.15 mm
Max. extrusion output:
HDPE: 40-70 kg/h
LDPE: 50-100 kg/h

High‑Efficiency Extrusion System: The screw and barrel are made of 38CrMoAl alloy steel, with nitriding treatment + precision grinding for wear and corrosion resistance. The 32:1 L/D ratio ensures uniform mixing and plasticization, with stable melt temperature, large extrusion volume and low energy consumption.
High‑Speed Stable Production: Output 40–70kg/h (HDPE) and 50–100kg/h (LDPE). Equipped with dual stabilizing rings, automatic air ring and closed‑loop tension control for stable bubbles, thickness accuracy ±0.001mm, no vibration and few film breaks at high speed.
Precision Die Head & Cooling: Center‑feed spiral die head with polished and chrome‑plated flow channel for uniform discharge. Dual‑air‑port cooling ring + high‑power centrifugal fan provides high cooling efficiency, resulting in high transparency, good gloss and no wrinkles for high‑speed printing/bag making.
Intelligent Automation: PLC + touchscreen with automatic temperature control (±1℃), auto meter counting, auto stop on web break, closed‑loop tension. Friction double winder + torque motor ensures neat winding and easy roll change. Optional on‑line thickness gauge + edge trim recycling saves labor and reduces waste.
Wide Material Compatibility: Suitable for HDPE/LDPE/LLDPE, producing 100–1200mm fold width, 0.009–0.15mm thickness films. HDPE for ultra‑thin high‑strength films; LDPE for thick high‑toughness products.
Durable & Easy Maintenance: Variable‑frequency main motor saves 20%+ energy. Gearbox with forced lubrication + oil cooler ensures long‑term stability. Hard‑anodized and dynamically balanced guide rollers ensure smooth, low‑noise operation with low maintenance costs.
