Dear Migros

Is it not possible to make these white-green paper bags with the perforated plastic window only from paper without a plastic window? Firstly because plastic should generally be avoided wherever possible and here it is possible, secondly because all the "sauce" from my mini pizzas, for example, seeps out of this perforated plastic window and thus messes up my other purchases or my hands every time. I know what I'm putting in the bag, so I don't need a window to see what's inside. You can also print the Migros logo on the white paper edge.
