⚙️ Key Production Specifications
The USMD-H2-65 dual-layer polyethylene film blowing machine is designed for efficient HDPE film manufacturing with a maximum extrusion capacity of 70 kg/hour. The system produces two film rolls simultaneously with a width of 600 × 2 mm, enabling high productivity in industrial environments. The adjustable film thickness range of 0.008 mm to 0.08 mm allows manufacturers to produce both ultra-thin packaging film and stronger protective plastic layers.

🔩 Advanced Extrusion Mechanism
This equipment is equipped with an extrusion screw diameter of ϕ65 mm, which enhances polymer melting efficiency and improves material flow stability. The extrusion die configuration ϕ50/60 × 2 ensures symmetrical film formation on both sides. The machine operates using an industrial electrical supply of 380V / 50Hz / 3 phase, ensuring reliable and stable performance during continuous operation.

📏 Industrial Structure and Equipment Size
The machine has an overall dimension of 5.5 × 3.4 × 4.3 meters, making it suitable for installation in modern production facilities. Its engineered frame provides structural durability and stable performance during long working cycles. The film blowing structure supports consistent air pressure and temperature distribution, ensuring uniform film texture and controlled thickness.

🏭 Industrial Application Areas
The USMD-H2-65 system is widely used in packaging material production plants, plastic processing factories, and industrial film manufacturing facilities. It is ideal for producing HDPE shopping bag film, courier packaging rolls, industrial wrapping film, garbage bag film, and agricultural plastic covering materials. The double-roll production capability improves manufacturing efficiency for companies requiring large-scale film output.

♻️ Operational Stability and Production Benefits
This extrusion line is optimized to maximize raw material efficiency while maintaining consistent product quality. The balanced mechanical configuration ensures smooth polymer distribution and stable film formation. As a result, manufacturers can achieve reliable film rolls suitable for bag-making machines, packaging converters, and large-scale plastic processing operations.
