[Harry Potter] Is plastic used in the Wizarding World? Do magical people even know what it is and what it can do?

Plastic has always struck me as a muggle material -- either because magical folk don't know how to synthesise it and/or they don't want to use it. However, does it exist in the Wizarding World? Do magical folk have an alternative to plastic?

Hardly seems like a necessary invention when they can mold metal and wood (and rat) into any shape or mechanical part they need.

Wizards would probably have come across it in their dealings with muggles (however brief.), and would be able to recreate it if the need ever came up. 

Maybe shoe lace aglets. The rat ones are generally too loud when stepped on.
