Is your business primarily shipping products bought online and not sold in retail stores? If yes, then take a look at how Amazon.com packs its items. I buy personal products from Amazon all the time. They never have more than their smiley face on the packaging. Its just a brown box and the product itself is packaged with regular bubble wrap or actually surrounded by inflated plastic bag like things connected to each other. The thing to note is that there is hardly any branding on the packaging. And I can see why... Unless your product is competing against other packaged products on a retailers shelf, jostling for yoru buyer's attention, why would you need exterior packaging? It will be a good idea, but it will also be worth the analysis to see if it really benefits you. The purchase decision is made on your webiste (right?).
If you are talking about products sold in a retail outlet, then you are right on as far as your quest for marketing on packaging. Wish you luck.
