EXTRUSION BLOWN FILM LINES
Solutions for blown films surface treatment
IEEC’s RFI Corona Treatment System is a perfect solution to all problems related to surface treatment for blown films. The rigid mechanical structure ensures absolute uniform air gap across the web width, ensuring perfect treatment levels at all times. The system is available in segmented as well as fixed type electrode structure.
Technical advantages include:
- Web widths up p 3000mm
- Line speeds up to 200mpm
- Single or double sided treatment
- Corona Treater Rollers covered with high dielectric grade silicone sleeves
- Electrodes coated with corrosion resistant chemical
- Aluminium segments in widths of 3mm or 10mm
- Electrode head fabricated out of stainless steel
- Pneumatically actuated treating heads for easy threading of the films.
- 1dler rollers at film entry & exit to ensure wrap angle of film with treater roller
