i just found it interesting when the OP said he found a paperwallet in a zippy bag.. and also it wasnt just a passphrase but a QR code which is more of what i call a 'bitnote'(as demo's in image) rather than a paper wallet (hand wrote key on paper)
The now scamming paper wallet site used to sell CDs, tamper proof stickers and ziplock bags, basically making it a complete package of anything you need except for a printer. Ziplock bags are quite common anyway, I use them for my phone and wallet too when cycling through the rain.
