Would this be possible within a manufacturing setting?

Yes. The nice thing about radio frequency identification is that passive tags can be read through plastic materials. So embedding a tag in a plastic container would actually protect the tag. However, the tags used must be able to survive the injection-molding process. Transponders must use solder that will not melt under high levels of heat, as might exist at a manufacturing site.

We recently published a story about a company called Würth Elektronik embids, which has begun marketing a line of tags designed for physically demanding use cases, including embedding in containers (see Würth Elektronik Manufactures a Tougher Breed of Tag). Other companies, such as William Frick & Co. and Metalcraft also offer tags able to withstand high heat and the injection-molding process.
