Achieving High Barrier Performance in Coextruded Films

This is a Past Course

Recorded on Jul 8, 2020

Reach higher barrier performance levels in your multilayer thin films with coextrusion for any type of packaging goods without compromising on mechanical properties (strength, stiffness…) and sustainability.

Thomas Bezigian will share how to innovate barrier film design logic (including material selection, prediction of coextruded barrier film performance…) within limited trials to save time reaching optimal barrier performance.

Why should you view this course?

When trying to improve barrier properties of the coextruded films, there are several parameters to consider. For instance, the environmental conditions, manufacturing technique to be used, should the end-product be recyclable/sustainable?

But, due to lack of method, you spend a lot of time in trials. You need to be quick to stay competitive. Understand the design logic & break the barriers! 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.
