Good tip! I've seen all sorts of little packets re-used... wrappers from individual teabags, drink mix packets... as you said, sometimes you just have to look around! The paper "footballs" we used to shoot across our school desks make a good little packet also, but not as flat as your bandaid wrapper.
Bandaids here are mostly opened by a 4 year old. Needless to say, their wrappers can't be recycled like this!
