1. Product Introduction
In the competitive landscape of plastic packaging, performance and reliability are the keys to profitability. The monolayer blown film machine by E-shion Machine is a precision-engineered solution designed for processing HDPE, LDPE, and LLDPE resins. This high-performance monolayer blown film extrusion machine is widely utilized for manufacturing liquid packaging, industrial liners, garment bags, and high-strength garbage bags.
By integrating advanced alloy components with intelligent control systems, we provide a machine that delivers consistent film thickness and high clarity while minimizing energy consumption. For a full view of our manufacturing capabilities, you can also visit our Made-in-China Showroom.
2. Core Technical Advantages
Superior Extrusion with 30:1 L/D Ratio
The heart of any extrusion line is the screw and barrel. We utilize high-quality 38CrMoAlA alloy steel, which undergoes a specialized nitrogen treatment and precision grinding process.
- Optimum Hardness: This ensures the screw is highly resistant to wear and corrosion, even when processing recycled materials.
- Superior Plasticizing: Our 30:1 L/D (Length-to-Diameter) ratio allows for a longer melt path. This ensures that the plastic granules are perfectly homogenized, eliminating “fish eyes” and ensuring the film has superior tensile strength and a smooth finish.
Precision PID+SCR Temperature Control
Thermal stability is critical for film quality. Our machines are equipped with digital PID temperature controllers paired with SCR (Silicon Controlled Rectifier) power modules.
- Stable Thermal Management: Unlike traditional contactors, the SCR system provides a steady flow of power to the heaters, maintaining a precise temperature curve. This prevents polymer degradation and reduces energy costs by up to 20%.
Direct-Connection Gearbox Design
Efficiency begins with the drive system. E-shion’s monolayer blown film extrusion machine features a high-torque, direct-connection gearbox.
- Mechanical Efficiency: By eliminating the energy loss associated with belt-driven systems, this direct-drive design ensures stable torque output, lower noise levels, and reduced vibration during high-speed operation.
Advanced Auxiliary & Winding Unit
- Double-Rolling & Double-Cutting: Our coiling unit is designed for high-volume production, allowing for seamless roll changes without stopping the line.
- Torque Motor Tension Control: Every roll is wound with consistent tension, ensuring flat, wrinkle-free film that is ready for secondary printing or bag-making processes.
- Gusset Device: Included as a standard feature, allowing you to produce side-folded films for T-shirt bags and grocery bags immediately.
3. Diverse Applications
Our machinery serves as the backbone for various plastic production sectors. The films produced are ideal for:
- Retail Packaging: T-shirt bags, vest bags, and laundry bags.
- Industrial Protection: Mattress covers, furniture wrapping, and textile liners.
- Sanitation: Heavy-duty garbage bags and medical waste bags.
- Food Industry: High-clarity liners and liquid packaging films.

5. Maintenance and Long-Term Reliability
To ensure your monolayer blown film machine runs at peak performance for years, we recommend:
- System Purging: Regularly clean the screw when switching between HDPE and LDPE to prevent carbonized residue.
- Lubrication Management: Check the gearbox oil levels monthly to maintain smooth power transmission.
- Heater Inspection: Periodically verify the SCR modules to ensure all heating zones are functioning accurately.
