In German supermarkets, minced meat is usually sold in a plastic box under what’s described as a “Schutzatmosphere” (protective atmosphere).
It looks like this:
Not visible in this image, the meat is always placed on a sheet of paper. Why is that done? I haven’t found the meat to stick to the plastic more than to the paper, and I can’t think of a reason why the meat would go bad faster without the paper. Also, the plastic boxes usually have a grill-shaped bottom, so the meat would probably not sit in any liquid coming from it.
