Silver is a very soft metal so a few hours in the mill should be enough time to remove any silver present on the plastic mylars.
You would have a big mess and very little silver recovered, if any at all. The first mistake would be shredding them.
What I meant to add is that when using shredders, mills and other devices that causes friction WILL make the mylar/plastic melt and stick to each other and you'll have trapped silver in the melted plastic.
I've been there and done that! It will not work.
