Course Overview

This two-day program provides a broad overview of blown film extrusion, including materials, hardware, and processing methods. Hands-on sessions on a laboratory blown film line are included. Upon completion of this seminar, attendees will be able to:

  • describe how all parts of an extrusion line interact with plastic material to affect final product performance and quality
  • identify various polymer materials used to produce blown film and discuss important film properties
  • discuss in detail the hardware specific to blown film processing, including screws and dies
  • describe how bubble geometry creates the molecular structure that influences film properties
  • troubleshoot both extruder and film problems

This course includes a copy of Dr. Kirk Cantor’s book, Blown Film Extrusion, An Introduction – 3rd Edition by Kirk Cantor (Hanser Publication).
