A Three Layer Blown Film Plant is a co-extrusion film line with three extruders feeding a three-layer die (ABA/ABC configuration). It produces multilayer polyethylene (PE) films with enhanced barrier, strength, and performance compared to single layer lines.
Extruders
Number: 3 extruders (A/B/C) for co-extrusion.
Screw diameter: typically 45 mm 120 mm (customizable).
L/D Ratio: approx. 28:1 32:1.
Barrel & screw: nitrided / bi-metallic for wear resistance with grooved feed.
Heating Zones: multiple PID controlled heating zones on each extruder.
Drive System
AC motor drives with variable frequency drives (VFD) for speed control.
Gearbox: helical type with built-in bearings.
3-Layer Co-extrusion Die: Spiral or ABC type for uniform melt blending.
Die diameter: typically 150 mm 300 mm or as per width requirement.
Air Cooling Ring: Dual-lip or IBC (Internal Bubble Cooling) preferred for uniform thickness and stable bubble.
Auxiliary heat exchanger & blower included.
Output Capacity
Typical range: 50 kg/h 650 kg/h, depending on extruder size and configuration.
Film Properties
Thickness range: 10 300 m (most commonly 20 150 m).
Layflat width: 200 mm 2700 mm+ depending on model and die size.
Gauge control: 5 % (typical) using auto thickness measurement systems.
Haul-off units: Adjustable speed haul-off with oscillating platform optional for gauge randomization.
Winder: Surface or pneumatic rewinder, single/dual station.
Options: centre slitting, side trimming, web aligning.
PLC Touchscreen control system for monitoring and adjustments.
Optional features include:
Gravimetric dosing system (for precise resin feed).
Auto thickness & width measurement.
Recipe storage and supervisory control panel.
Primary Polymers: LDPE, LLDPE, HDPE, metallocene resins.
Others: EVA, biodegradable compounds, compound blends.
Power: 3-phase 380415 V supply.
Compressed air: 6-8 bar for blowers/control valves.
Cooling water/air: for cooling tower / chillers.
Corona treater for improved printability.
Gravimetric dosing & blending for precise melt composition.
IBC system for superior bubble cooling and film properties.
Auto winding & thickness control systems.
