Polymers in Packaging - 2 Day Course

Course Number: AP3546
Date: 04/14/2021 - 04/15/2021
Time: 8:00 AM - 4:00 PM
Location: Akron Polymer Training Center, Akron, OH 44325-5404, U.S.A.
Cost: $2,000.00 USD
Online Registration

Course Overview

This two day course will present just enough polymer chemistry to allow the attendees to fully understand how polymers are built, how they are melted, how they are formed and why plastic packages behave the way they do. Along the journey we will cover all the basic plastic molding methods and discuss the common polymers used in packaging applications.
