The other day I looked at a common 6-pack and took notice, for once, of the cardboard crate which protected my precious cargo. “How was it made?” I asked. So apart it came! Check this out.
So it’s not the coolest thing ever, but you have to admit this is pretty neat. That whole 6-pack carton was folded up from one piece of cardboard; and (regarding the evenly spaced glue lines) it was probably glued and folded in an automated machine producing multiple finished cartons per second.
Some dude had to figure out how to fold this carton constrained to use print and glue on only one side of the raw stock, make it so a machine could automate all the glue and fold operations, and do it all while wasting minimal cardboard. Here’s to you Mr. Packaging Engineer dude!
