Not sure what it is called but its kind of similar to grease proof paper but you can sort of see through the wrapper - Sandwiches that is, and there is our own personalized sticker with the contents on the front.
Wraps/baguettes are heat sealed in clear plastic with cardboard backing.
Bagels use the same as sandwiches with cardboard as well.
We could have used ribbon, plastic boxes and all sorts but that increases the price.
Oh and with the green issues everyone at work wants simple packages now!
