The Heavy Duty Industrial Plastic Blown Film Machines are robust production systems designed for high-volume manufacturing of polyethylene (PE) films in packaging, construction, and agricultural sectors.

|---|---|
Engineered for 24/7 operation, these machines feature a sturdy steel structure, high-output extruders, and advanced cooling systems to produce films with uniform thickness and mechanical properties at scale.
Massive Production Capacity
High-Output Extruders: Double-screw extruders (120-200mm diameter) with deep-flight screws, processing 1,000-2,500 kg/h of PE resin (LDPE/LLDPE/HDPE blends).
Large Bubble Diameter: Die heads (300-1,200mm diameter) support film widths up to 6,000mm, ideal for wide-format applications like tarpaulins and industrial liners.
Durable Construction
Heavy-Gauge Steel Frame: Stress-relieved welded steel structure (15-20mm thickness) with anti-vibration mounts, ensuring stability at maximum output.
Corrosion Resistance: Chrome-plated rollers and stainless steel contact parts for processing corrosive additives (e.g., masterbatch with metal oxides).
Efficient Cooling System
Dual Air Ring Technology: Inner/outer air rings (1,200-2,400mm diameter) with variable speed blowers, reducing cooling time by 20% and improving film clarity.
Water-Cooled Condenser (Optional): For high-humidity environments, maintaining consistent bubble stability and thickness control.
User-Friendly Operation
Touchscreen Interface: Centralized control of extrusion temperature (±2°C), blower pressure, and winding tension (0-50 N/m).
Quick Die Change System: Hydraulic lifting mechanism reduces die maintenance downtime to <60 minutes, enhancing productivity.
Packaging: Production of garbage bags, shopping bags, and heavy-duty industrial sacks (80-200 micron thickness).
Construction: Manufacturing polyethylene sheeting for waterproofing, vapor barriers, and concrete curing.
Agriculture: Large-scale production of silage films, mulch films, and crop covers with UV-stabilized formulations.
Reliability for 24/7 Operation: Redundant lubrication systems and thermal overload protection ensure minimal downtime (MTBF >10,000 hours).
Energy Saving Design: Frequency converters on all motors and heat-insulated barrels reduce energy consumption by 15% compared to older models.
Localized Service Support: Regional warehouses stock critical spare parts (e.g., heaters, bearings) for same-day delivery in major industrial zones.
