Cosmetic packaging concept embodies complex technologies

31-Aug-07

The latest luxury cosmetics packaging concept developed by RPC Beauté has highlighted its expertise in complex project management and technologies. The design, which incorporates a vial, collar and cap- uses various technologies, including bi-injection, overmoulding, sonic welding and the recently developed technique of partial electroplating. Innovations include partial electroplating of a bi-material collar to achieve a combined translucent-metallic finish. The gloss vial is injected in copolyester and features a strong geometric shape despite large wall thickness variations. The surface is hot stamped with the Lancôme logo before being overprinted with a clear tampo print to enhance scuff resistance. To achieve the metallic-looking collar, the neck is bi-injection moulded from two different polymers and submitted to a partial electroplating process, which creates translucency and a metallic finish on the same part, with a quality of execution that no other technique can match. The cap is manufactured from an insert, moulded in a high resistance compound, which is then plated and finally overmoulded with Surlyn®.
