Innovative Technologies Help "Make a Statement"

DuPont is developing new technologies aimed at helping producers of leading cosmetic and personal care products

True to its slogan of "Make a Statement", DuPont is developing new technologies aimed at helping producers of leading cosmetic and personal care products give their brands a unique look and feel. These include the second generation of the company's electroluminescent technology for illuminated Point of Sale (POS) displays and cosmetic packaging concepts; and the use of sublimation printing for differentiated and attractive nomadic perfume delivery systems.

Light up your packaging with electroluminescence

Electroluminescent technology is based upon the use of conducting, insulating and luminescent 

 'Nomadic' perfume packaging 
  

In this 'nomadic' perfume package, a glass container is protected by a casing made of tough, transparent Surlyn® resin, further enhanced by an interchangeable, two-part outer shell made of DuPont™ Crastin® PBT polyester resin or DuPont™ Delrin® acetal resin. The molded outer casing can be decorated with sublimated dyes or fibers for brand aesthetic appeal. (Click on image to download

inks, developed by DuPont, which are suitable for manufacturing printed electroluminescent lamps. The printed circuitry is shielded by a tough, transparent outer-layer of DuPont™ Surlyn® resin.

In a further advancement of this technology, all of the electronic components have been further miniaturized, encompassing the integration of the driver into the printed electroluminescent film. This facilitates its incorporation in secondary packaging for cosmetic and personal care products. A demonstration of the progress made by DuPont in terms of this technology is the presentation of a prototype compact case at Luxe Pack 2006, made in cooperation with the UK company Toly Products Ltd and Seribase in France, in which a thin electroluminescent strip has been integrated to illuminate the brand name.

Sublimation printing

A second source of differentiation in packaging is offered by DuPont's adoption of sublimation printing on the casing of 'nomadic' perfume delivery systems. Representing a growing market segment, 'nomadic' is the term given to cosmetic and perfume products often carried in handbags or luggage, where the risk of accidental spraying or damage is greater.

In a response to this demand, DuPont had previously developed a glass/resin hybrid packaging concept, whereby the glass container for the fragrance is protected by a secondary casing made of tough, transparent Surlyn® resin. This has now been further enhanced to incorporate an interchangeable, two-part outer shell made of DuPont™ Crastin® PBT polyester resin or DuPont™ Delrin® acetal resin, which can be decorated with different colors and patterns by means of dye sublimation.

The process developed by DuPont uses a patented dye-carrier which adheres smoothly onto curved parts and complex geometries without wrinkling, producing high-precision patterns. Sublimated dyes, or fibres for a fabric effect, can penetrate into the material to a depth of between 0.2 and 0.3 mm, making the decoration highly resistant to wear, scratches and abrasion. The ability to incorporate sophisticated multi-color images, photographs or patterns onto the functional packaging of perfume and cosmetic products permits greater aesthetic appeal and brand differentiation.
