Why does a film badge have a plastic case and not a metal case?

The film has a dried silver emulsion on it which can be scratched and scraped if exposed to everyday handling. The plastic case is just there to hold the film in place and protect it from being scratched. The emulsion is on the reverse side, closest to your body, so nothing can touch it while it's in the case.

Once again, the metallic film will probably be aluminum, because it is cheap, easily melted for the coating process, and can take colours and dies for decoration.
