Crazy About Packaging: Conversations with the C.A.P. Pack · 2026-08-11 · 47 min
In this episode of Crazy About Packaging, the C.A.P. Pack - Natalie, Mike, and Jonathan - break down what high barrier food packaging actually does and why the right structure looks different for every product. From yogurt and coffee pods to ground beef and salsa, every food has its own needs for oxygen, moisture, light, sealing, and shelf life. This episode looks at how packaging teams balance those needs with cost and recyclability - without losing sight of the package’s most important job: protecting the product. Tune in to explore: What “barrier” actually means in food packaging and what it protects against Why barrier needs can vary so much between different foods and filling processes How materials like polypropylene, PET, polystyrene, and polyethylene handle oxygen and moisture Why barrier and shelf life aren’t the same thing - and how testing helps determine the right structure How added barrier layers can affect recyclability and why simpler isn’t always better If you're working toward longer shelf life, fewer materials, or more recyclable food packaging, this episode shows why those goals have to start with the product and its specific needs.
