Key Features

  • Dual-Screw AB Co-Extrusion System
    Independently driven screws for A and B layers allow flexible layering of materials, such as combining virgin and recycled film or adjusting optical and mechanical properties across layers.

  • Wide Material Compatibility
    Supports HDPE, LDPE, LLDPE, and EVA, offering excellent adaptability for producing different film grades, thicknesses, and end-use applications.

  • High-Efficiency Output with Low Energy Consumption
    Designed to deliver high production capacity (up to 180 kg/h) while maintaining reduced energy usage, ensuring lower production cost per unit.

  • Precision Screw and Barrel Design
    Specially engineered screw geometry promotes uniform plasticization and consistent material mixing, resulting in smooth film surfaces and stable thickness control.

  • Durable Gearbox System
    Equipped with a high-performance gearbox featuring enforced lubrication and integrated oil cooling to ensure smooth operation, even under heavy loads and long production cycles.

  • Adjustable Nip Roll Mechanism
    The vertical nip rolls can be adjusted in height, providing better control over film tension, take-up speed, and bubble stability during extrusion.


Performance Advantages

  • Stable and continuous production for both mono- and multi-application films

  • Reduced material waste through accurate control of film thickness and width

  • Flexible film layering options help meet various market requirements (e.g. optical clarity, strength, or cost-effectiveness)

  • Easy maintenance and long equipment lifespan due to reliable mechanical and thermal design

  • Compatible with modern downstream equipment (e.g. corona treaters, winders, and bag-making lines)


Application Areas

This two-screw blown film machine is suitable for producing a wide range of plastic films used in:

  • Food packaging (bread bags, frozen food film, produce wrap)

  • Industrial and retail carrier bags

  • Agricultural films (mulch film, tunnel film)

  • Lamination base film for flexible packaging

  • General-purpose wrapping or protective films
