My question would be are you sure you got it all and if not what harm would it cause, possibly get caught in one of the oil passages and plug it, that certainly wouldn't be a good thing. Talk about losing sleep!
What chances would it have of passing thru to the oil pan and draining out.
Not much you can do about it now except drive the [censored] thing and hope whatever, if anything, burns off.
I might consider running a strong solvent based flush like a Berryman's before a D&F in hopes that the solvents go to work on *any* plastic/cellophane that made it's way into the engine. Very good chance none did but you can't say for sure...so I think I'd err on the side of caution. Then keep a close eye on the oil pressure this next oci.
