I received a cbj from a WL but is was covered by a very thin plastic sheet ( that look like a small plastic bag)


I google and found out that this might be called a dental dam but dental dam is more like a square sheet of paper but what the WL used is more like a plastic bag shape.

Any bro know what is this plastic?

Assuming that it is a dam, is it an effective protection? Or same risk as a bbbj??

Thanks for any advice
