⚙️ Production Capacity and Key Figures
The USMD-H45/50 polyethylene film blowing machine is designed specifically for HDPE film production with a stable output of 30–40 kg/hour. It can manufacture film rolls with a maximum width of 600 mm, allowing efficient production for packaging materials. The film thickness can be adjusted between 0.008 mm and 0.08 mm, making the equipment suitable for producing both lightweight packaging film and stronger industrial wrapping material.

🔩 Extrusion Technology and Screw System
The extrusion unit is equipped with a dual screw configuration measuring ϕ45 mm and ϕ50 mm, which improves melting efficiency and maintains a steady polymer flow. The die head size ϕ60 / 80 mm ensures smooth film formation and balanced bubble expansion. The machine operates on an industrial electrical system rated 380V / 50Hz / 3 phase, providing stable energy supply for continuous manufacturing operations.

📏 Machine Structure and Installation Space
The overall equipment dimensions are 4.5 × 2 × 4.3 meters, making it suitable for installation in medium-sized plastic processing workshops. Its vertical film blowing tower design helps maintain consistent air pressure and temperature control. This structural arrangement contributes to uniform film thickness and improved surface smoothness.

🏭 Industrial Production Applications
The USMD-H45/50 system is widely used in plastic film manufacturing factories, packaging material production facilities, and recycling-based processing plants. It is suitable for producing HDPE shopping bag film, packaging liners, courier bag material, protective wrapping film, and lightweight industrial covers.

🧪 Material Processing Stability
Designed exclusively for HDPE polyethylene, the machine ensures stable melting and controlled extrusion flow during operation. The balanced screw configuration allows efficient processing of polymer granules, helping manufacturers maintain consistent film quality throughout long production cycles.

♻️ Operational Advantages and Efficiency
This film extrusion system improves raw material utilization while reducing production waste. The optimized mechanical design ensures stable performance, simplified maintenance procedures, and reliable output quality. As a result, manufacturers can achieve continuous film production suitable for bag making machines and industrial packaging converters.
