Why not?
You don't even necessarily need to put all disclaimers directly on the package. Just put some kind of reference number on there, like an MSDS number, and let users go look up all the packaging information online if necessary.
The manufacturer has this information. They must in order to produce the product. The requirement would be they just have to publish it now when used to wrap food.
How does that not "scale?"
