Achieving High Barrier Performance in Coextruded Films

This is a Past Course

Recorded on Jun 27, 2017

Design high barrier multilayer thin film structures with coextrusion for any type of packaging goods without compromising on mechanical properties (strength, stiffness…) and sustainability.

Learn from Thomas Bezigian on how to innovate within limited trials as he shares guidance on barrier film design logic (key requirements to material selection) and shows how to predict coextruded barrier packaging performance from film & resin permeability properties.

Why should you view this course?

End use requirements translate into package design requirements, which in turn becomes your job! To stay competitive, you have to innovate to reach higher barrier performance levels. But with limited amount of trials, it is difficult to break the barriers using existing structures… Join this course and:


  1. Save time reaching optimal barrier properties (OTR, WVTR...) in your novel film structures by understanding the design logic for various kinds of packaged goods

  2. Make the right selection of barrier material by reviewing the various materials available (polyamides, PVdC, EVOH, OPET, OPP...) and how you can make them work together via co-extrusion

  3. Predict the barrier performance of your co-extruded packaging from film & resin permeability properties before real scale trial

Coextrusion of thin film

Who should view this course?

Chemists, Engineers in Research & Development who are interested in improving the way they conduct multilayer extrusion to achieve high barrier properties in their thin layer products.
