When I covered some Loctite foam with plastic wrap from my kitchen I could remove it the next morning. But when I waited a day ... Not so much. That is my only experience. I had spritzed the foam with water before covering it and smoothing the foam under the plastic.

After a full cure it should be stuck there forever. Trick is to give it time to fully cure. And like is mentioned, it cures with moisture/humidity.
Lots of YouTube people use expanding foam in a can on plastics and don't have much issue after the full cure.
