Can someone please explain what the waxy paper on top of margarine is for? I don't know why it's there. Google doesn't seem to know either.
It doesn't seal the product, so it can't be to protect it from germs. Come to think about it, most tubs arnt even airtight. That seems strange for a good product in this day and age.
Please enlighten me
It keeps the surface from drying out, and the product from sticking to the lid.
