No, but i've only seen this once.

Btw, microplastics.

Nah. Also in Germany styrofoam is used for take away by some places. But it really sucks from my perspective. If you put really hot stuff in it (like fries straight from the fryer) it may melt and your fries have plastic shit attached to them and, since it doesn't allow condensate to exit the crispy food will turn soggy really fast. Carton is so much better from every perspective.

Luckily, legislation in the EU is trying to reduce single use plastics.

Fries need to breathe. Cardboard container wrapped in paper, the holes carved on the top to avoid them becoming soggy.
