Blown Film Extrusion - 2 Day Course

Course Number: AP3536
Date: 05/18/2020 - 05/19/2020
Time: 8:00 AM - 4:00 PM
Location: Akron Polymer Training Center, Akron, OH 44325-5404, U.S.A.
Cost: $1,000.00 USD
Online Registration
CEU's: 1.6
Instructor: Dr. Kirk Cantor

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).


Instructor Biography:

kirk-cantorKirk Cantor is a Professor of Plastics and Polymer Engineering Technology at Pennsylvania College of Technology in Williamsport, Pennsylvania, where he has taught since 1990. He obtained an MS and a Ph.D. in Polymer Science from The Pennsylvania State University, both in polymer extrusion related topics. Previously, he earned a BS in Aerospace Engineering from University of Maryland and worked for five years at NASA in the engineering of high-altitude polyethylene balloons. For the past several years, he has been actively involved in extrusion research and training and has developed many computer-based instructional products for the plastics industry. He is the author of the book “Blown Film Extrusion” from Hanser Publishers.
