The problem with using transparent packaging is that it is often brittle and degrades over a period in sunlight (or any kind of daylight). It would be disappointing to build it in and then discover after a year or so that it has gone yellow or fogged. I think some of it is intended to be biodegradable these days. I have tried using the boxes to store stuff in but usually find that they splinter after a year or so.
Some of the plastic packaging is more durable but I'm not sure how you tell this from the more fragile stuff.
