During high-speed PP (polypropylene) and PE (polyethylene) film production, friction and contact between the film and rollers can generate significant electrostatic charges. These charges attract airborne dust, cause film sticking and winding problems, and may increase the risk of electrostatic discharge in certain production environments.
KESD Ionizing Air Bars provide effective static elimination for PP and PE film production lines by delivering balanced positive and negative ions to the charged film surface. This helps neutralize static electricity, reduce dust attraction and improve process stability in film extrusion, slitting and rewinding applications.
Static electricity is a common challenge in plastic film manufacturing, especially during continuous, high-speed processing.
Typical problems include:
Dust Attraction: Electrostatic charges attract airborne particles, affecting film cleanliness and surface quality.
Film Sticking: Static attraction causes film layers to cling together, making handling and separation more difficult.
Uneven Winding: Electrostatic forces can interfere with film separation and winding, affecting roll consistency.
Production Interruptions: Static-related handling issues may reduce production efficiency and increase the need for cleaning.
Electrostatic Safety Risks: In environments containing flammable vapors or combustible dust, electrostatic discharge may present an ignition hazard.
Effective static control for plastic film production helps reduce these issues and supports more stable manufacturing processes.
KESD Ionizing Air Bars are designed for continuous static elimination on moving film surfaces.
Installed at an appropriate distance above or beside the film web, the ionizing air bar generates positive and negative ions that travel toward the charged material. These ions neutralize the electrostatic charge, helping reduce the film's residual static electricity.
Key benefits include:
Fast Static Neutralization: Helps reduce electrostatic charge on continuously moving PP and PE films.
Wide-Area Coverage: Treats a broad section of the film web, depending on bar length and installation conditions.
Non-Contact Operation: Eliminates static without direct contact with the film surface.
Production-Line Integration: Can be installed at suitable locations along extrusion, slitting and rewinding lines.
Improved Film Cleanliness: Helps minimize electrostatic dust attraction and supports cleaner film handling.
Actual performance depends on the ionizing bar model, operating distance, film speed, environmental conditions and installation configuration.
During film extrusion and downstream cooling, the film may accumulate static as it passes over rollers and other contact surfaces. An ionizing air bar installed at a suitable downstream position helps neutralize surface charges before subsequent processing.
Slitting creates new film edges and involves repeated contact and separation between film layers. Static elimination near the slitting or web-handling section helps reduce dust attraction and film adhesion during processing.
During rewinding, electrostatic charges can cause film layers to cling together and interfere with smooth roll handling. Installing an ionizing air bar near the rewinding section helps reduce static buildup and supports more consistent winding operations.
