The body of a plastic bottle is typically electroplated by first applying a conductive layer to the surface. This can be done using a vacuum metallization process, where a metal coating is evaporated and deposited onto the plastic surface.
Once the conductive layer is in place, the plastic bottle is immersed into an electroplating solution that contains metal ions . A current is then applied to the solution, causing the metal ions to be attracted to the conductive surface of the plastic bottle. The metal ions then deposit onto the surface, forming a thin metallic layer that adheres to the plastic substrate.
