I suspect this landed here due to the abundance of search results linked to APUG for "silver+coated+paper+plate" all very photographic related terms used in combination quite ofetn. In reality, "silver coated paper plate" as a phrase has nothing to do with our interests, though it has provided an interesting channel of thought! Understanding search engines and how they work might better benefit the OP in their quest of healthy living using man made materials...
