Multilayer coextrusion line LF series

11-layerblown filmplastic film

Description
Multilayer co-extrusion blown film lines for industrial film production, available in 2 to 11 layers. Models include LF-250, LF-400, LF-600, LF-700, LF-800 and LF-1000. Extruder screw diameters range from 12.5 mm (conical) up to 60 mm. Pancake-type dies developed with Compuplast consultant John Perdikulas ensure precise layer distribution. Lines produce large lay-flat widths and can be equipped with optional modules for process control, cooling and winding.

Key features

• Layer range: 2 to 11 layers
• Extruder sizes: 12.5 mm (conical) to 60 mm
• Pancake-type die design (Compuplast consultant)
• Optional duplex high-efficiency air cooling ring
• Oscillating nip-roll for uniform roll formation
• Control options: digital panels to full computerization
• Single- or multi-station wind-ups
• Computerized gravimetric hopper feeding for precise layer ratio control
• Tower options with motorized height adjustment (model dependent)
