Paper and plastic packaging are marvelously complex. The paper is light weight, but sturdy, often in the form of corrugated cardboard, which needs a good glue to function - already we have multiple ingenious engineering feats that need factory scale production. To print things we need inks and printing mechanisms which is a whole other branch of technology. And then we often add plastic coatings or wrappers to that, giving it some weatherproofing or additional solidity.

When you look at what's happened to fashion, what we've done lately - you know, since the 40's or so, when the tech really started to get going - is mostly to come up with fancy plastic bags to wear over ourselves. But those are building on millennia of textiles and weaving, even so.
