Team penalized for dumping fries on field in Potato Bowl No, rust is a form of oxidation which happens to iron specifically.
Plastics can corrode via acid (depending on the type of polymer and acid) and even more analogous to rust on iron for plastic is UV radiation (the stuff in sunlight) this radiation can cause the polymeric molecules to break and this weakens the plastic. Polymers are long chain like molecules that tangle together, when non-polymeric additives are added to the mix the resulting product is a plastic.
Not all types of plastic react the same to UV just as not all metals have the same degree of vulnerability to oxidation. If you are more curious because of a specific item you have, you would need to identify the type of plastic and go from there.
