⚙️ Primary Production Parameters
The USMD-HM45 mini polyethylene film blowing unit is engineered for compact plastic film manufacturing. It produces film with a maximum width of 500 mm and supports thickness ranges of 0.008–0.08 mm (HDPE) and 0.02–0.10 mm (LDPE). The extrusion capacity reaches 70 kg/hour for HDPE and 40 kg/hour for LDPE, providing flexible performance for different polymer grades.

🔩 Extrusion System Configuration
This machine integrates a precision extrusion screw with a diameter of ϕ45 mm, ensuring consistent polymer melting and stable material flow. The extrusion die size ϕ60 mm allows accurate shaping of the film bubble. The equipment operates on 380V / 50Hz / 3-phase electrical supply, enabling steady industrial operation and reliable thermal control during long working cycles.

📏 Compact Industrial Design
With an installation footprint of only 1.45 × 2.28 × 3.2 meters, the USMD-HM45 is considered a space-efficient solution for facilities with limited production areas. The vertical film blowing tower ensures stable air circulation and balanced tension across the film surface, improving uniformity and product consistency.

🏭 Material Compatibility
The equipment supports multiple polyethylene materials including HDPE, LDPE, and LLDPE. This versatility allows manufacturers to switch production depending on packaging requirements. The system can process different resin formulations while maintaining stable extrusion flow and uniform film formation.

📦 Industrial Usage Sectors
The machine is widely utilized in packaging production plants, plastic processing workshops, recycling-based film manufacturers, and small industrial converting facilities. It is suitable for producing shopping bag film, packaging liners, courier bag rolls, protective wrapping film, and agricultural plastic sheets.

♻️ Operational Benefits and Productivity
The USMD-HM45 provides efficient raw material utilization while maintaining controlled extrusion stability. Its compact mechanical arrangement simplifies installation and reduces maintenance complexity. As a result, manufacturers can achieve continuous film production, predictable thickness control, and dependable output performance in daily industrial operation.
