The gas or vapor is driven to move from an area of high concentration to an area of low concentration. This video shows a simplified explanation of how water vapor transmission rate tests are conducted. • To ensure packaged products or packaging materials will provide the desired product shelf life, protection and safety – it is critical to understand the gas permeation rates through both the barrier materials and the final finished package, and select packaging materials and designs that can meet your shelf life needs. • In practical applications, the transmission rate (TR), is the most common way to report the “flux” of gas moving through a polymer. The transmission rates for oxygen (OTR), water vapor (WVTR) and carbon dioxide CO2 (CO2TR) can be measured by permeation instruments with different sensor technologies. For packaging films, permeation rates are typically reported as: cc/m2day for OTR and CO2TR and g/ m2day for WVTR. • From gas transmission rate analyses, it is possible to determine how long it will take for a bottled soda pop product to go flat (even without opening the product), the time it takes a protective atmosphere to reach ambient conditions, and ultimately, whether your packaging is providing the gas permeation protection that is desired. • Gas permeation analysis can also be used to monitor the quality of raw packaging materials as it goes from film through conversion to the final packaged product. Often, even small material changes can cause significant changes in gas permeation rates – with a large consequence to the atmosphere that a product experiences during its packaged lifetime. Gas permeation analysis for quality control in the packaging materials, converters and food beverage industries are some of the largest uses of permeation analysis equipment today. • Introduction 0:00 • Permeation Basics 0:12 • Purpose of Barrier Packaging 0:55 • Permeation Mechanism 3:48 • What Does It Look Like? 4:56 • Permeant/Polymer Relationship 6:02 • Solubility 9:11 • Oxygen Solubility Within Polymers 10:29 • Diffusion 12:08 • Permeability 13:56 • Temperature Impact Upon Permeation 14:35 • Multi-Temperature Studies 15:33 • OTR Bottle Testing 20.9% (Room Air) vs. 100% O 17:18 • Example of Using Permeation Units 21:09 • Relative Humidity 23:43 • Factors That Influence Permeation Time 25:44 • Effect of the Chemical Substituents On the Polymer Backbone 27:38 • Material Thickness 28:10 • Multiple Layers 29:57 • How To Test Films 30:40 • What conditions will it be exposed to? 31:55 • How Are You Going To Get It There? 33:12 • How Do You Test Packages? 34:14 • Example: Testing of Small Pouches 34:51 • Testing Packages 35:15 • Closing: 36:10 • Visit our website https://www.ametekmocon.com for more information and resources. • © AMETEK MOCON 2019 YouTube Videos, Educational Webinars and Webinar Slides by AMETEK MOCON are licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.
