Expert Insights & FAQ

The extruder screw diameter determines the output capacity (kg/hr), while the die head diameter and Blow-Up Ratio (BUR) determine the film's layflat width. To spec a machine, you should define your target width and thickness first, then work backward to determine the required output and screw size. How do I spec the right extruder size for my target film width?

Extruder size is determined by output demand: a 55mm screw delivers 80–120 kg/hr, while a 90mm screw reaches 300–400 kg/hr. Always spec the machine by working backward from your target layflat width and film thickness. film-blowing-machine-extruder-calculation

By upgrading to servo drive systems (saving 28-34% on haul-offs), implementing OEE monitoring, and optimizing IBC cooling systems, manufacturers can significantly reduce energy draw per kg of film. Energy saving blown film tips
