Troubleshooting Low Output in Blown Film Extrusion

Expert solutions for improving blown film productivity through die head, extruder, and cooling system optimization

Low output

Blown film productivity is mainly influenced by the die head, extruder, and cooling effect. Here are common checks and actions:

Too High Pressure of Die Head?
Check for screen changer blockage. Consider using a higher MI polymer, increasing the die size or gap size, or raising the extrusion temperature.

Is the Bubble Stable?
Refer to the Solution of Unstable Bubble above for guidance on stabilizing the bubble.

What About the Extruder Motor?
Replace a malfunctioning motor, increase the extruder temperature, or use a higher MI polymer to improve performance.
