Clemson University offers both undergrad and graduate degrees in Packaging Science. For those of you designers interested to learn more about packaging, but who don't want to go back to school, I've just learned that Clemson has licensed their curriculum out to The Packaging School, an online learning venture.
The Packaging School offers certificate tracks, but you can also take courses a la carte, for edification's sake. I looked at what courses they offer in the design space, and they're as follows:
This is a fundamentals course, created by structural package designer Jane Scates because she couldn't find anyone else offering a discrete course on how to design for corrugated. If you already have an ID degree, some of this might remind you of sophomore year, but Scates goes a bit deeper:
"Platen: hard anvil diecutting, platen: soft anvil diecutting, cylinder-rotary hard anvil diecutting, cylinder-rotary soft anvil diecutting, rotary pressure cutting, and rotary crush cutting. Within these lessons we will cover the setup, processes, tools, and types of cutting required for each diecutting technology. We will then get into the converting process—covering cutting, creasing, scoring, perforating-serrated cutting, embossing, and debossing. We will conclude this course with an interactive lesson on the 'sins' of diecutting—key variable converting failure characteristics."
