A “simple” candy box tweak turned into a six-year redesign—because in packaging, changing a quarter inch can force you to rethink the entire manufacturing line.00:00 Why a ¼-Inch Box Change Took 6 Years (Packaging Equipment)00:17 Charlotte Ashcroft Intro: Mike and Ike + Peeps Packaging00:47 What Is Packaging Engineering? Automation, Materials, Structure01:41 Mike and Ike Box Redesign: What Actually Changed02:52 Designing Packaging Backwards from the Pallet (Pallet Optimization)03:17 Headspace Explained: Damage, Settling, “Half-Empty” Complaints04:26 Hidden Carton Upgrades: Right-Sizing + Tamper-Proof Design07:49 Sustainability Wins: Fewer Trucks + Source Reduction11:38 Mike and Ike vs Peeps: Why “Gooey” Products Need Different Packaging14:02 3 Questions New Candy Brands Must Ask (Equipment, Shelf Life, Distribution)17:44 Shelf Life Testing: Chamber Studies + Packaging Barrier Basics27:20 EPR + SB 54: Recyclable Packaging Regulations + Real-World ImpactIn this episode with Charlotte Ashcroft, we unpack what packaging engineering really means—and why the stuff most designers never see (automation compatibility, headspace, pallet patterns, tamper-proofing, distribution reality) is where the real money, speed, and sustainability wins happen.You’ll learn:• What packaging engineering actually covers (beyond “structure”)• Why automation dictates more design decisions than people realize• The real reason “headspace” exists—and how it affects damage, complaints, and line speed• How engineers design backwards from the pallet (and why it saves trucks/material)• The hidden structural tweaks (glue, flaps, tamper-proofing) that change everything• How regulations like EPR / SB 54 push packaging decisions years in advanceIf you’ve ever thought “it’s just a box”… this one will permanently change how you look at packaging.Connect with Charlotte:LinkedIn:https://www.linkedin.com/in/charlotte-ashcraft/Packaging & Processing Women's Leadership Network:https://www.pmmi.org/womens-leadership-network/homeLarger Events:https://www.packexpoeast.com/https://www.packexpointernational.com/Support our Sponsor, and download your free Packaging Design Guide:https://idpdirect.com/design-guides/Connect with Evelio Mattoshttps://www.linkedin.com/in/eveliomattos/
