Blown Film Machine

Blow Film Machine is an industrial equipment that melts plastic particles by heating and blows them into thin films, widely used in packaging, agriculture, construction and other fields. Its core processes include extrusion plasticization, blow molding, and cooling shaping, ultimately forming thin film products with specific thickness and properties.

High Efficiency & Quality

Max speed up to 80m/min for efficient single- or multi-layer film production; films feature smooth finish, high strength, and durability for diverse uses.

Advanced Heating & Stability

Automatic temperature control saves energy, meets environmental standards, and ensures consistent film quality.

Precision Transmission & Strength

Equipped with frequency-conversion haul-off and winding for precise, uniform output; spiral-core head ensures full plasticization and stronger film.

Wide Compatibility & Flexibility

Supports HDPE, LDPE, and LLDPE. Produces films from 0.006–0.08mm thick, adapting to various applications with strong production flexibility.

How does your Blown Film Machine ensure film quality (thickness uniformity, strength)?

A: Our machines use 3 key technologies:

  • Servo motor control: Precise speed regulation for consistent thickness (±1-3% tolerance)
  • Auto-air ring: Adjusts cooling air flow to prevent film bubble instability
  • PLC control system: Stores 100+ production recipes for repeatable qualityCompared to competitors, our film has 15% higher transverse strength and 10% better thickness uniformity.  Contact us view third-party test data for verification.

How to choose the right Blown Film Machine model for my production needs?

A: Focus on 4 key factors:

  1. Film width: Match the machine’s maximum width to your target product (e.g., 1000mm machine for 800mm films)
  2. Material type: Standard models for PE; special screws for biodegradable materials
  3. Production volume: Calculate monthly 需求 (kg) and choose a machine with 10-20% extra capacity
  4. Energy efficiency: Industrial models have inverter motors (30% energy savings vs. standard motors) Take our 2-minute assessment for personalized model recommendations.

What raw materials are compatible with your Blown Film Machine?

A: The machine works with:

  • Virgin granules: LDPE, LLDPE, HDPE (MFI 0.5-10 g/10min)
  • Recycled materials: Up to 30-50% recycled PE granules (depending on purity)
  • Additives: Color masterbatches, anti-UV agents, anti-blocking agents (mixed in advance)
  • Special materials: Biodegradable resin blends (requires screw modification).We recommend material moisture content <0.05%—follow our raw material drying guide to avoid film defects.

What is the production capacity of your Blown Film Machine?

A: Capacity depends on model and film specifications:

  • Small lab-scale model: 50-150 kg/day (film width 300-600mm)
