Achieving High Barrier Performance in Coextruded Films

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

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.
