I'm baking cookies but don't have cookies sheets, what can I use instead?
I don't know where you got your data and what areas of can use you are covering but I do know that a lot of things that used to be in steel cans are now being packaged in plastic, plasticized cardboard and in some cases glass.
Stretch aluminum foil on the oven rack, an spray a little pam on it
The cans are getting smaller? Perhaps the manufacturers want to make more money by making the cans hold less.
