I don't know if it is considered foil packed, rather pouched. Because the container really isn't foil and I'd think burning it would be pretty awful. Pack it in and pack it out, but it's better than trying to bring in a can and with the actual products they come out better than they do out of a can anyway.

Chuck if that were a strict rule I think many of us would be in trouble. I use zip lock baggies for just about everything, and most container's are not reusable or burnable. I think as long as it's not glass or a can your doing just fine.
