Low thickness flat PP foils Extruders

Air Knife System for PP Foil Production

• Functionality:
  • The air knife system generates a laminar air flow directed at the molten polymer as it exits the extrusion flat die.
  • This controlled air stream pushes the extruded material uniformly against the calender roller, ensuring:
    • Consistent contact with the roller surface
    • Stable processing conditions
    • Improved surface finish of the foil
• Purpose and Benefits:
  • Guarantees the production of uniform, high-quality PP foils
  • Enables the achievement of very low and consistent thicknesses
  • Enhances the dimensional stability and optical properties of the foil
  • Reduces the occurrence of air bubbles, thickness variations, and surface defects
• Post-Processing Capabilities:
  • The resulting PP foil can be laminated for various specialized applications, such as:
    • Food packaging (for improved barrier properties)
    • Medical and pharmaceutical packaging
    • Decorative films
    • Printed multilayer structures
